The purpose of the current research is treatment of cotton seeds with appropriate pesticides and foliar application with plant compounds in a way that be effective in control of first-season sap sucking pests in cotton fields. This experiment was designed to study the effect of several treatments including: 1-seed treatment with Thiamethoxam (Cruiser®), 2-seed treatment with Thiodicarb (Larvin®), 3-seed treatment with Imidacloprid (Gaucho®), 4-foliar application of insecticidal soap containing coconut oil (Palizin®), 5-foliar application of botanical insecticide containing pepper extract (Tondexir®), 6-foliar application of imidacloprid (Confidor®), and 7-control for control of first-season sap sucking pests in cotton fields. This research was carried out in a randomized complete block design with five replications at Darab Agricultural Research Station during two years (2020 and 2021). Seed treatments with Larvin® and Gaucho® were applied only in the second year of experiment. The results of the first year of the experiment showed that the cotton seed treatment with Cruser® kept the cotton seedlings free from the cotton aphid (Aphis gossypii Glover) until one month after the sowing date compared to other treatments that were applied as foliar spraying. The results of statistical analysis 41 days after sowing date showed that the most effective control method of onion thrips (Thrips tabaci Lindeman) is seed treatment with Cruiser®. The results of the second year of the experiment showed that Cruzer®, Larvin®, and Gaucho®, which were impregnated with cotton seeds, caused a significant decrease in the population density of cotton whitefly nymph [Bemisia tabaci (Gennadius)] until the end of the sampling period (41 days after sowing date). Foliar spraying of seedlings with herbal compounds (Palizin® and Tondexir®) in both years initially had a significant effect on reducing the population of aphids and whiteflies, but with increase of the time, their effect was less than other treatments. Based on the results of the present research, seed treatment with Cruzer® not only offers more control against cotton seedling sucking pests (onion thrips, cotton aphid and cotton whitefly), but also can be a better option in terms of economy, user's health and environmental effects.

The white peach scale, Pseudaulacaspis pentagona, is one of the most important pests of stone fruit trees in the northern provinces of Iran. The efficacy of several synthetic and biorational insecticides was investigated on white peach scale in a peach orchard in Shirang-E-Olya village of Kamalan district in Aliabad-E-Katoul city. The study was conducted in a randomized complete block design with 9 treatments and four replications in the peach orchard. Treatments in this experiment include: Pyriproxyfen (EC10%) at the rate of 1 and 2 ml/L, Chlorpyrifos (EC 40.8%) at the rate of 4 and 8 ml/L, Thiacloprid (OD 24%) at the rate of 0.6 and 1.2 ml/L, Spirotetramate (SC 100) at the rate of 1 and 2 ml/L, Flupyradifurone (SL 20%) at the rate of 1 and 2 ml/L, Palizin (SL) at the rate of 3 and 1.5 ml/L, Tondexir (EC) at the rate of 4 and 8 ml/L, Citral (EC) at the rate of 1 and 2 ml/L and control. Sampling was performed 1 day before spraying, and then the first and second generation of this pest after spraying. Data were analyzed by Glm method and means were compared by Duncan multiple range test using SAS software. Spirotetramate (1 ml/L) had the highest efficacy percentage among the insecticides used on the first generation of this pest. For the second generation also, the highest efficacy was observed by Spirotetramate (1ml/L) and Chlorpyrifos (4 ml/L). Among the bio-insecticides, 1.5 ml/L of Palizin and 8 ml/L of Tondexir were highly effective, too. Although chemical insecticide such as Chlorpyrifos showed good results, the new insecticide Spirotetramate had the same or better efficacy than Chlorpyrifos. Therefore this insecticide can be a suitable substituted for chlorpyrifos. Biorational insecticides also had good effect in eliminating white peach scale and can be used as biocompatible insecticide.

Melon aphid Aphis gossypii is one of the economic pests of melon that has a high adaptability to various environmental conditions, including salinity. In this study, the lethal and sub-lethal (LD10) effects of Palizin soap insecticide (0, 450, 696, 1078, 1669, 2583 and 4000 ppm) were investigated on A. gossypii reared on melon seedlings under salinity stress (0, 20, 40 and 60 mM) in a Factorial experiment based on completely random design in growth chamber (25 ± 1°C, %70 ± 5 RH and 16L/8D h photoperiod). Bioassay was performed based on leaf deep bioassay method. The LD50 values after 24 hours were estimated as 1378, 1036, 860 and 749 ppm for treatments, respectively. An inverse relationship was observed between the toxicity of Palizin and increase in salinity. To determine the effect of LD10 of Palizin on aphids, biological parameters of insect fertility in each salinity treatment were determined based on the age-stage, two-sex life table theory. The nymphs had longer development duration in treated aphids than aphids that grew under similar salinity conditions, but adult insects had a shorter longevity and less fecundity. The average of intrinsic rate of increase varied from 0.31 to 0.17 ♀/♀/days-1 and the average of generation time varied from 11.16 to 12.65 days between 0 and 60 mM salinity treatments. Based on the results, Palizin insecticide with salinity stress can be recommended for successful integrated management of aphid on melon under salinity stress conditions.

Canola is an important oilseed crop in the world. Cabbage aphid, Brevicoryne brassicae is one of the most important pests of canola crop in Iran. In this study, the effect of chemical control of cabbage aphid was investigated in autumn and spring on Hyola 401 cultivar. For this purpose, spring and autumn sprayings with imidacloprid and pirimicarb at 1/1000 concentrations and insecticidal soap at 2.5% concentration were assessed using a randomized complete block design. The experiments were conducted during two growing seasons, 2011 and 2012 in Qazvin province. The results showed that, both autumn and spring spraying is necessary for pest control. Autumn and spring sprayings with imidacloprid caused 99.5 ± 0.4%, 94.5 ± 2.4% and 95.4.1 ± 1.0% mortality in 2011 and 99.1 ± 0.5, 86.9 ± 2.7 and 93.1 ± 5.5% mortality in 2012, three, seven and 15 days after treatment, respectively. Highest yield achieved at imidacloprid treatment and was 3533.00 kg/ ha. If not controlled, the damage would be 66.18, 69.35 and 78.0% at spring, autumn and spring-autumn treated plots.

The orange pulvinaria scale, Pulvinaria aurantii Ckll. is the most important scale of citrus in the northern Iran. The lethal effects of chlorpyrifos, pyripropoxyfen, acetamiprid and palazin, alone and in combination with emulsifying oil, were evaluated on first-instar nymphs of P. aurantii. The experiment was conducted under natural condition in a randomized complete block design with 3 replications and 10 treatments, and treatments effect was compared 1, 7, 14 and 21 days after spraying. Moreover, the effect of these insecticides was investigated on duration of immature stages and female longevity of Cryptolaemus montrouzieri Mulsant. The activity of some detoxification enzymes (alpha-esterase, beta-esterase and glutathion-S-transferase) in third instar larvae was evaluated. The experiments on the ladybird were conducted under laboratory conditions at 26±1ºC, 75±5% RH and a photoperiod of 14:10 (L:D) h. The treatments with acetamiprid + oil, pyripropoxyfen + oil, chlorpyrifos + oil and palazin + oil had the highest mortality on first nymphal instar of the scale. The longest incubation period of C. montrouzieri was in chlorpyrifos treatment (8.13 days), and the shortest was in control (4.80 days). Moreover, among treatments the female longevity of C. montrouzieri was the longest in control (96.60 days), and shortest in chlorpyrifos treatment (53.50 days). Chlorpyriphos and acetamipirid caused the highest reduction in alpha-esterase and glutathion-S-transferase activities of the third larval instar of C. montrouzieri, respectively. Also, palizin had less negative effect on the activity of beta-esterase in comparison with other tested insecticides. The results of this study indicated that among tested compounds, palizin in combination with the oil is a suitable compound to control of the orange pulvinaria scale.

 Fig mite, Eotetranychus hirsti Baker & Pritchard (Acari: Tetranychidae), is one of the most important pests of fig trees in Iran and most parts of the world. This pest causes the leaves to fall and reduce the quantity and quality of the product. Several different insecticides have been used to control this mite. Due to the consumption of fresh fig and in order to produce healthy crops and to develop non-chemical pesticides, the application of coconut botanical soap (Palizin® SL70%), red pepper extract (Tondexir® EC85%), and propargite (Omite®, EC57%,) were tested in the fields of Bardaskan region, during 2015-2016. The botanical insecticides (1500 & 2000 ppm concentrations), propargite acaricide (2000 ppm) and water were sprayed over the whole canopy during July to August. Samplings were carried out one day before and 3, 7, 14, 21 and 28 days after spraying. At each sampling time, the total number of egg, larvae and active stages (nymph and imago) of fig mite on 4 leaves per tree were counted. Treatments were compared based on mortality rate and efficacy percentage. Data was analyzed based on a completely block randomized design using SAS software. Mean comparison was done using Tukey's test. The results of this study showed that there was a significant difference between all treatments and different times, on all developmental stages of fig mite. Based on the field studies, the application of botanical components, including the red pepper extract, compared with the propargite acaricide, caused a further decrease in the population of fig mites. The highest mortality rates for eggs, larvae and active stages (nymph and imago) of fig mite were observed in red pepper extract and coconut botanical soap treatments, and the lowest mortality rates was recorded in control treatment. The mean efficacy percentage of red pepper extract (2000 ppm) treatment for eggs, larvae and active stages (nymph and imago) were 97.9, 95.1, 92.2 in 3 days, 98.7, 94.2, 93.5 in 7 days, 96.0, 88.9, 89.3 in 14 days, 98.8, 93.7, 92.8 in 21 days and 97.1, 96.8 and 92.7 in 28 days after spraying, respectively. Also, the mean efficacy percentage of coconut botanical soap (2000 ppm) treatment for egg, larvae and active stages (nymph and imago) were 88.9, 89.2, 87.0 in 3 days, 89.2, 87.7, 86.3 in 7 days, 87.1, 86.0, 87.6 in 14 days, 86.6, 83.5, 83.4 in 21 days and 87.5, 87.6 and 90.9 in 28 days after spraying, respectively. Therefore, red pepper extract (Tondexir®) spraying with 2000 ppm concentration, over the whole canopy of figs trees, were effective in decreasing fig mite damage.

  Alfalfa (Medicagosativa L.) is a high-quality forage crop widely grown throughout the world. This plant is attacked by a wide range of pests.Alfalfa weevil, Hyperapostica(Gyllenhal) (Coleoptera:Curculionidae), is a pest of concern in alfalfa on the globe. This introduced pest is most problematic in the early season, causing defoliation and reduced yield and quality. Both adults and larvae feed on alfalfa, but the larvae cause the majority of the damage to terminals, foliage, and new crown shoots. This pest has many natural enemies. Among the beneficial insects, the green lacewing, Chrysoperlacarnea (Stephens) (Neuroptera: Chrysopidae), has received special attention since its larvae are important natural enemies of alfalfa weevil. The control of H. postica was done by chemical pesticides .There is now overwhelming evidence that some of these chemicals do pose a potential risk to humans and other life forms and unwanted side effects to the environment. Palizin (Coconut soap) is a natural compound based coconut extract. In the current research work, the effect of this compound on the adult of H. postica and egg and 1st instars larvae of C. carnea was investigated under laboratory and field conditions. postica: H. postica larvae were collected from alfalfa fields in Miandoab using sweep nets in July 2016 and taken to the laboratory. Larvae were placed in plastic dishes (5 × 10 × 20 cm), fed by alfalfa foliage, and held at 25 ± 2 °C, 75±5% RH to complete their growth and convert to adults. The adults were used for all tests. C. carnea adults were collected from alfalfa field at the Miandoab region, taken to the laboratory for identification of species and reared in the laboratory. Clear plastic cylinder containers (with 15 cm diameter × 25 cm height), which were covered with a mesh cloth were used for rearing. A thin layer of food source (mixture of yeast 50%, water 25% and honey 25%) was smeared to a plastic tape which was inserted into the plastic container. Water was provided for the adults through a wet sponge placed on the mesh cloth. To harvest the eggs, the adults were transferred to fresh containers every day. The eggs were laid on a colored paper which was attached to the interior wall of the cage. The eggs hatched after 3 days and the first larvae were used for bioassay. First, primary experiments were performed to determine the minimum and maximum concentrations. Afterward, seven concentrations and also control were considered. Concentrations used for Palizin were 400, 543, 737, 1000, 1357, 1842 and 2500 ppm and for Fenvalerate were 200, 265, 353, 468, 622, 827 and 1200 ppm. Adult were kept at 4 °C to be inactive. Then, 15 adults were release on the petri plate (with 9cm diameter and 1.5 cm height). Using spray potter tower, 500 microliter of each concentration was sprayed on the petri and the dishes were placed in a growth incubator at 25±2˚C, 65±5% RH. To evaluate the recommended concentrations (2500 ppm Palizin and 1000 ppm Fenvalerate), an experiment was conducted in a randomized complete block with three treatments and five replications under field conditions. The number of H. postica (adults and larvae) and C. carnea (larvae) was counted day before and 3, 7, 14 and 21 days after treatment. Statistical analyses: The mortality results were analyzed using SPSS data processing software. Significant differences among the groups were determined using the unpaired Duncan-test in 5 % level of significance.The percentage of population reduction in the treatments was corrected in relation to the control (water) by Henderson and Tilton’s formula under field condition. Insecticides may be a good option if other options have not sufficiently controlled alfalfa weevil. Several com mercially available products are labeled for control of alfalfa weevil. Although effective, their repeated usagehas disrupted natural biological control systems and led to resurgence of this pest, resulted in the development of resistance and had undesirable effects on no target organisms. In order to prevent resistance, effective chemical control of the pest requires new insecticides with novel modes of action. In laboratory condition, the LC50 values of Palizin and Fenvalerate on H. postica were 601.72 and 321.87 ppm 24 h after treatment, respectively. Toxicity of Fenvalerate for egg and 1st instars larvae of C. carnea was higher than Palizin. The LC50 values of this insecticide were 563.02 and 178.46 ppm and the LC50 values of Palizin were 1664 and 1663 ppm. The results of field trial showed that Palizinhas a longer persistency effect. According to IOBC standards, Palizin and Fenvalerate were categorized as slightly toxic and very toxic to C. carnea, respectively. The plant pesticide used in this research caused the high mortality on the adults of H. posticawith proper persistency. In addition, its toxicity is less than Fenvalerate to C. Carnea and can be applied as an effective alternative to chemical insecticides in alfalfa fields.

Two-spotted spider mite, Tetranychus urticae Koch is one of the most important polyphagous pests because of severe damage, high population growth rates and ability of making resistance to pesticides. In this research, contact toxicity of concentrations of Sirinol, Tondexir and their combination, and also repellency effect of Palizin were studied in order to find a proper substitute for synthetic acaricide and to omit their pollutant effects on the environment. The experiments were performed at 25±2 C, %60±5 relative humidity and 16:8 (L:D) on adult females by leaf dipping method. Sirinol at 5700 ppm and Tondexir at 5300 ppm concentrations created the highest mortality. LC50 and LC90 values of Sirinol and Tondexir were, 1775.908, 16772.6 and 2130.914, 11975.205 ppm in 24 hours and 463.228, 5985.136 and 907.931, 6052.447 ppm in 48 hours, respectively. Combined application of Sirinol and Tondexir (LC25) caused %66.66 mortality at 24 hours which was higher than mortality caused by their separate application. Palizin was ineffective at 250 ppm concentration, but at 500, 1000, 2000 and 4000 ppm showed repellency activity. According to these results, the combinations of tondexir and sirinol and repellency effect of palizin was high and can be suggested in the integrated pest management programs of this mite.

Gerbera is attacked by a large number of pests, one of the most important of which is greenhouse whitefly (Trialeurodes vaporariorum Westwood). Currently, it is controlled by chemical and large amounts of money are used to import insecticides to control this pest annually. In current research, the effect of Palizin and Imidacloprid in T. vaporariorum control in commercial gerbera greenhouses was compared. The experiment was performed in a commercial greenhouse in Pakdasht, Tehran. The same size and none flower gerbera pots were selected for further analysis. Before and after the experiment, the number of nymphs and adults were estimated. Selected factors were included: the pesticide in two levels, pesticide dose in three levels (0.5, 1 and 1.5), application time in three levels (hours 8, 12 and 16) and replications in a month in three levels (2, 4 and 6). Data was analyzed using Design Expert 10 software with RSM (Response Surface Method) method. Based on the result, the mortality percentage of whitefly adults during the use of Confidor is significantly higher than Palizin. Also the only significant factor was the pesticide type, and other factors will not make any significant changes in the response.

The crapemyrtle aphid, Tinocallis kahawaluokalani Kirkaldy, is an important pest of ornamental woody plant, Lagerstroemia spp. causes premature drop of leaves and decline of summer flowering and reduces the commercial market. Effect of botanical insecticide, Palizinat the recommended concentrations of 1500, 2000 and 2500 ppm evaluated on aphidand its predator, Harmonia axyridis Pallas.Experiment was done on aphids by two methods leaf dipping and spraying and then the numbers of dead aphids were recorded at 24 after treatment. The results showed that spraying method was more effective than other method and caused 86.6%, 90% and 95% mortality at 1500, 2000 and 2500 ppm of Palizin, respectively. By dipping eggs of coccinellid in insecticide solutions the lowest eggs hatching percent (50%) and the longest developmental period (19 days) were observed at 2500 ppm of Palizin. Eggs hatching percent and developmental period were slightly affected by 1500 ppm of Palizin in comparison with the control. By topical application of Palizin on the fourth instar larvae, the survival of larvae and pupal developmental period were not significantly affected. However, the highest survival of treated fourth instar larvae (96.9%) than control (100%) was observed at 1500 ppm of Palizin. According to the results, Palizin at 1500 ppm had remarkable mortality on aphids without affecting many of tested characteristics of H. axyridis. So, Palizin at 1500 ppm can be used for integrated pest management in integration with H. axyridis to control of T. kahawaluokalani.

The harmful plant mites not only feed on crops, but also have irreversible damage to humans. The synthetic pesticides can be replaced with natural products for pest control. The agricultural products, health and hygienic of humans can be treated with harmful caused by the mites (Wooley, 1988). The citrus red mite (CRM) Panonychus citri (McGregor) (Acarina: Tetranychidae) is one of the most important herbivorous pests in citrus growth area. For the first time, this pest was reported from Mazandaran province in 1940. The nymph and adult of these pests create identified small, silver and gray spot on leaves and fruits. As a result of feeding, contamination can cause necrosis of leaves, loses of young leaves and reduce the plant freshness. The synthetic of pesticides has been used for controlling of this pest for a long time. The application of non-normative methods for control of the mites can cause pest outbreaks and destroy the natural enemies of the pest. This pest has been resistant to a wide range of pesticides such as; Dicofol, Hexythiazox, Abamectin and Pyrothroids in field conditions. In recent decays, the organic agriculture has been grown dramatically. Lio (2003) has reported that at least 30 countries produce organic citrus fruit. So, for growing organic citrus in Iran, it also suggested to use the low impact pesticides to the environment and the human health. In this research, the comparison toxicity of three botanical pesticides Tondexir (red pepper extract), Sirinol (garlic extract), Palizin (eucalyptus extract) with two common chemical pesticides (Hexythiazox and Fenpyroximate) and common mineral oil has been investigated against adult and protonymph of citrus red mite P.citri.
The citrus red mite (CRM) has been collected from infected trees from citrus orchard and brought into the lab; after that, the adult and nymphs were separated. The citrus red mite has been reared on citrus leaves in growth chambers with constant condition (25 ±2oC, 16:8 L/D and 60% RH conditions). The primary test has been done to identify the maximum and minimum concentration. For bioassay experiments, the citrus leaves were washed and cleaned with distilled water and prepared in 20 mm diameter leaf disc. The bioassay was carried out using leaf dip methods with different concentration of the following pesticides after primary experiment: Mineral oils (2000, 2828, 4000, 5657 and 8000 ppm), Tondexir (1000, 1368, 1871, 2559 and 3500 ppm), Sirinol (750, 1102, 1620, 2381 and 3500 ppm), Palizin (2000, 2378, 2828, 3364 and 4000 ppm), Hexythiazox (250, 370, 548, 811 and 1200 ppm) and Fenpyroximate (500, 679, 922, 1252 and 1700 ppm). The mortality was recorded at 24, 48 and 72 h after-treatments. All experiments were conducted with three replications. The statistical analyses were performed by SPSS version16.0 software.
The Probit analysis was shown that the LC50 value of the mineral oils on protunymph and adult of citrus red mite were 1743.6 and 1898 ppm, the LC50 value of the Tondexir were1305.9 and 1549 ppm, the LC50 value of the Sirinol were 666.1 and 693.9 ppm, the LC50 value of the Palizin were 2206 and 1969.2 ppm and the LC50 value of the Hexythiazox were 223.6 and 227.3 ppm at 72 h post-treatments, respectively consequently and the probit analysis was revealed that the LC50 value of the Fenpyroximate on protonymph and adult of citrus red mite were 480 and 439.3 ppm at 72 h post-treatments, respectively. Consistent with our result, the acaricide, Hexythiazox had higher toxicity on adult and protonymph of CRM in comparison to the other pesticides. Among three botanical pesticides, Sirinol has the highest toxicity. Due to the low risk of three botanical pesticides, they should be considered in IPM program.
The data analysis of this research was shown that among different compounds, the highest and lowest toxicity on adult and protonymph were obtained with Hexythiazox and Plazin consequently respectively. By comparison the LC50 values, the protonymph was more susceptible than adult. With regards of being low risk and natural products of the botanical pesticides and mineral oils for humans, it is better to use these products to control red mites.

One of the common methods for controlling of greenhouse whitefly Trialeurodes vaporariorum in tomato greenhouses is use of chemical and botanical insecticides. To evaluate the effects of these insecticides on adult female of predatory bug Macrolophus caliginosus these research was carried out using botanical insecticides (Sirinol, Palizin and Tondexir) and chemical insecticide (Imidacloprid) in 0, 0.5, 0.9, 1/8 and 3 ml/l in three methods; glassy tubes in laboratory, pot and greenhouse experiments on tomato plant. There were significant differences between treatments, doses and interaction of doses and treatments. The mortality was increased with increasing the doses. 48 hours after spraying, highest and the least mortality was caused by Imidichloprid (3 ml/l.) with 100% and Palizin (0.5 ml/l.) with 23.8 % mortality, respectively. In pot method, the highest mortality of predatory bug was caused by Imidichloprid (3, 1.8 ml/l.) with 97.23 and 94.34%, and the least mortality was caused by Palizin (0.5 and 0.9 ml/l.) with 20.17 and 21.14 %. Imidichloprid (3, 1.8 ml/l.) had the highest mortality with 94.46 and 92.66 % and Palizin (0.5 and 0.9 ml/l.) had the least mortality with 17.5 and 18 % on predatory bugs in greenhouse condition. In all three methods, there were significant difference between Imidichloprid (all doses) and the other botanical insecticides. These results show that the botanical insecticides could be used as natural products in IPM programs to protect the natural enemies.

The effect of three botanical insecticides (sirinol, palizin and tondexir) and one chemical insecticide (imidacloprid) on Trialeurodes vaporariorum has been investigated in laborarory and greenhouse conditions.The four insecticides were used with different doses of 0.5, 0.9, 1.8 and 3 ml/lit respectively. The leaf-dip assay for nymph and glass tube assay for adult were used. Also the effect of these insecticide on tomato plants in green house was studied. There were significant differences among used insecticides and interaction between doses and insecticides on all nymphal stages and adults of the greenhouse whitefly (GW). The mortality rate increases with increasing doses and decreases with increasing nymphal age. There were not significant differences among different doses of Imidicloprid and Tondexir (3 ml/l) on the first, second and third instar nymph of GW in leaf-dip assay. The imidicloprid (3 ml/l) had the highest mortality on fourth instar nymph of GW and was categorized in separate group. Also in pot experiment the highest mortality in all of nymphal instars was for Imidicloprid 3 ml/l, however the tondexir 3ml/l had similar affect on second instar nymph. The highest mortality in adults (with no significant differences) occurred using Imidicloprid was obtained with Imidicloprid (3 ml/l), Tondexir (3 ml/l), Palizin (3 ml/l), Imidicloprid (1.8 ml/l) and Sirinol (3 ml/l) with 98.03, 96.07, 96.07, 96.07 and 94.11 % mortality respectively.

To alleviate insect pest problems in storage, synthetic pesticides are recommended, but their use may create toxicity to non-target organisms, development of resistance and residues in treated products. Under such circumstances the need for research to find a safe, convenient, durable and economically logical method is necessary. The application of repellents could be considered as a new control method in storage. In this study the repellency effect of Coconut soap (Palizin®) was assayed on Tribolium castaneum (Herbst) and Lasioderma serricorne (F.). Adults and larvae of T. castaneum and L. serricorne exposed to 0, 0.5, 1, 5 and 10% concentration of Coconut soap (Palizin®) (botanical compound) using three techniques such as: filter papers, Y- shape Busvine tube and leaky glass bioassays. In each of three methods, the maximum repellency effect of Coconut soap (Palizin®) was in concentration of 10%, and, the quantities were equal to 78.87, 74.27 and 56.93% for adults of T. castaneum and 72.70%, 85.86% and 45.60% for L. serricorne in Petri-dish, Y- shape Busvine tube and leaky glass techniques respectively.
