به منظور بررسی تاثیر تراکم علف هرز و میزان کود فسفر بر ویژگی های رشدی و نحوه تخصیص ماده خشک در گیاه زراعی گلرنگ و علف هرز خردل وحشی، آزمایشی بصورت کرت های خرد شده درقالب طرح پایه بلوک های کامل تصادفی با سه تکرار در مزرعه تحقیقاتی دانشگاه بیرجند در سال زراعی 99-98 اجرا شد. فاکتورهای آزمایش شامل سطوح کود فسفر (چهار سطح صفر، 25، 50 و 75 کیلوگرم فسفر خالص در هکتار) به عنوان عامل اصلی و تراکم خردل وحشی (چهار سطح صفر، 14، 28 و 56 بوته در متر مربع) به عنوان عامل فرعی در نظر گرفته شد. نتایج مقایسات میانگین نشان داد بیشترین میزان وزن خشک برگ گلرنگ با 48/35 گرم در متر مربع در 165 روز بعد از سبز شدن در تیمار شاهد (عدم وجود خردل وحشی) بدست آمد و کمترین میزان وزن خشک برگ نیز با 23/28 گرم از تیمار تراکم 28 بوته خردل وحشی حاصل گردید. بیشترین مقدار شاخص سطح برگ کل گیاه گلرنگ معادل 67/1 در 210 روز پس از سبز شدن از تیمار 25 کیلوگرم در هکتار مصرف فسفر حاصل گردید و کمترین میزان این شاخص نیز برابر با 19/1 از تیمار 50 کیلوگرم مصرف فسفر به دست آمد. همچنین بیشترین شاخص سطح برگ بوته خردل وحشی در 165 روز بعد از کشت (63/0) در تراکم 56 بوته خردل وحشی در متر مربع بوده و کمترین میزان این شاخص در این مرحله (26/0) از تراکم 14 بوته حاصل شده است. به صورت کلی مشاهده شد که ارتفاع گیاه و شاخص سطح برگ در گیاه خردل وحشی در شرایط تراکم بالاتر در همه ی مراحل رشد بیشترین مقدار بوده که نشان دهنده ی رقابت پذیری علف هرز می باشد. هرچه تراکم علف هرز بالاتر رفته ارتفاع گیاه زراعی بیشتر شده است، اما این افزایش تراکم علف هرز منجر به کاهش شاخص سطح برگ گیاه زراعی گردیده است.

Therefore, achieving any success in increasing the amount of production and supplying as many of these products as possible to meet the domestic needs of the country is considered a valuable and great success. Safflower, with the scientific name Carthamus tinctorius L., is an annual long-day plant from the chicory family. Wild mustard (Sinapis arvensis L.), which is also called Brassica kaber in some literatures, is one of the most important weeds belonging to the Brassicaceae family. Competition can perhaps be considered the most important biological interference factor effective in determining crops productivity.Effective management of weeds in agricultural systems is very decisive. Extensive and repeated use of herbicides has led to the emergence of resistant weed biotypes, which has often increased the cost of control. It has also caused some concerns about the negative environmental effects of herbicides. When the competition is for light, the competitive ability of the species is first determined by the morphological traits. The response of crop height to weed competition is related to the density and intensity of competition and the type of weeds and can be positive or negative.
Materials and MethodsAn split plots experiment based on randomized complete block design with three replication was carried out in the Research Farm of University of Birjand during the 2018-2019 cropping year. The treatments include four level of phosphorus fertilizer (0, 25, 50 and 75 kg P 2O5 ha-1) as the main plot and the four wild mustard densities (0, 7, 14 and 28 pl m-2) as subplots. Plant growth characteristics were measured from 150 to 210 days after planting (DAP) in five stages at 15-day intervals. Also, at the harvest maturity, the yield and yield components of the crop were determined.
Results and DiscussionAccording to the results, the highest (35.48 g m-2) and lowest (28.23 g m-2) safflower leaf dry weights were obtained from control (no-mustard) and 28 pl m-2 mustard densities at 165 DAP, respectively. The highest (1.67) and lowest (1.19) leaf area index of safflower were achieved at 210 DAP using 25 and 50 kg P 2O5 ha-1, respectively. Based on these results, it can be concluded that the most effective level of phosphorus on the improvement of safflower growth traits (e.g. leaf area and dry weight and stem dry weight) and its competitive ability was 25 kg P2O5 ha-1, although the its effects were not significant for many traits, and as phosphorus levels increased, the competition shifted more in favor of wild mustard. In accordance with these results, and probably due to luxury consumption by weeds, it has been observed that when weed density is high, adding fertilizer leads to superiority of weed growth over crop (Blackshaw et al., 2008). Also, the highest leaf area index of mustard (0.63) was obtained at a density of 56 mustard pl m-2 at 165 DAP and the lowest one of (0.26) was observed at a density of 14 pl m-2 at the same time. It was also observed that the height and leaf area index of wild mustard were the highest in all measuring stages at higher weed densities, indicating the competitiveness of the weed. The increase in weed density had a negative impact on the safflower, although insignificant in many cases, which could be the result of the competitive effect of mustard for resources such as radiation and nutrients (Wright et al., 1999).
ConclusionIn general, the increase in weed density had a positive effect on the yield and its components in wild mustard and a negative effect on the safflower, and under these condition, the application of more than 25 kg P2O5 ha-1 does not have a positive effect on the crop. Thus, it seems that the revision in weed management and the use of fertilizer as an agronomic strategy can be effective in reducing the crop losses caused by the presence of high densities of weeds (Clements et al., 2014).

Here, we present a catalogue of all mesostigmatid mites (except Phytoseiidae) reported from Iran. The catalogue lists 616 species belonging to 183 genera and 51 families. Considering the number of genera and species of phytoseiid mites, which is stated to be 15 and 105, respectively, the number of mesostigmatid mite genera and species in Iran reaches 198 and 721, respectively. The suborder Monogynaspida Camin & Gorirossi is more specious than Trigynaspida Camin & Gorirossi, and the latter is more specious than the Sejida Kramer. Oplitis inopina (Hull, 1923) is recognized as the earliest recorded description of mesostigmatid mites from Iran in over a century. The family Laelapidae, described and recorded from Iran, has the highest number of genera (26) and species (162), followed by Phytoseiidae (15 genera and 105 species) and Ascidae (10 genera and 49 species). The most specious genera are Gaeolaelaps Evans & Till (30 species), Laelaspis Berlese (21 species), and Macrocheles Latreille (19 species). The highest number of described species from Iran belongs to Gaeolalelaps (Laelapidae) with 15 species. No description has been done for the following reported families of monogynaspid mites from Iran: Ameroseiidae, Haemogamasidae, Macronyssidae, Dermanyssidae, Spinturnysidae, Rhinonyssidae, Varroidae, Parholaspididae, Otopheidomenidae, Podocinidae, Halolaelapidae, Veigaiidae, Epicriidae, Microgyniidae, Dithinozerconidae, Polyaspididae, Trachytidae, Metagynuridae, Trachyuropodidae, Cillibidae, Dinychidae, Urodinychidae, and Urodiaspididae. For Trigynaspida (except Diplogyniidae) and Sejida (except Sejidae), no species have been described from Iran. It is worth mentioning that the superfamily Anictequoidea, family Messoracaridae, and genus Messoracarus Silvestri are reported for the first time in Iran. Based on the published information for each species, information about geographical distribution, taxonomic literature, and host or habitat is included. Defects in the previous checklists have been corrected, and the classification of the known species has been updated.

In recent years, the research on the Iranian Chrysididae has been extremely prolific, thanks to the efforts of different teams. After the first checklist published by Rosa et al. (2013), more than one hundred taxa of cuckoo wasps have been recorded as new for Iran, including nine taxa described as new for science. Moreover, major modifications impacted the taxonomy of the family with two genera revaluated (Chrysellampus Semenov-Tian-Shanskij, 1932 and Colpopyga Semenov-Tian-Shanskij, 1954), Pseudochrysis Semenow, 1891 reintroduced for Pseudospinolia Linsenmaier, 1951; the description of the genus Morphochrysis Rosa & Pavesi, 2023 and several taxonomical changes to species level which were published and that deeply changed the first checklist, namely. As a consequence of all these fragmented changes, we propose a new, updated checklist of the Iranian species, to summarize all the new findings published in the last years. We describe eleven new species for science, Chrysis amerii Rosa & Farhad, sp. nov., C. chamrosh Rosa, sp. nov., C. crenulata Rosa, sp. nov., C. edentata Rosa & Baiocchi, sp. nov., C. peri Rosa & Baiocchi, sp. nov. and C. titanica Rosa, sp. nov. (succincta group), C. mediasignata Rosa, sp. nov. (leachii group), C. heimi Rosa, sp. nov. (maculicornis group), C. simurgh Rosa, sp. nov. (subsinuata group), Chrysura filidichroa Rosa, sp. nov. (dichroa group) and Hedychridium personatum Rosa, sp. nov. with its own new species-group. We report twenty-six new records of Chrysidinae for Iran: Chrysidea disclusa (Linsenmaier, 1959); Chrysis afghanica Linsenmaier, 1968; C. cylindrica Eversmann, 1858; C. echidna Semenov-Tian-Shanskij, 1967; C. grohmanni bolivari Mercet, 1902; C. klio Balthasar, 1953; C. laetula Semenov-Tian-Shanskij & Nikol'skaya, 1954; C. leuconoe Semenov-Tian-Shanskij, 1967; C. maracandensis Radoszkowski, 1877; C. mirabilis Radoszkovsky, 1877; C. mossulensis Abeille de Perrin-du Buysson, 1887; C. pseudobrevitarsis Linsenmaier, 1951; C. robertsi Rosa, 2020; C. rutilans Olivier, 1791; C. turcomana Semenov-Tian-Shanskij & Nikol'skaya, 1954; Chrysura laodamia laodamia (du Buysson, 1900); Euchroeus pellucidus (Radoszkowski, 1877); Hedychridium bytinskii Linsenmaier, 1959; H. mochii Strumia, 1994; H. plagiatum (Mocsáry, 1883); Hedychrum concinnum (Mocsáry, 1909); H. semicyaneum Mocsáry, 1889; Spinolia stchurovskyi (Radoszkowski, 1877); Spintharina extrema (Semenov-Tian-Shanskij & Nikol’skaya, 1954), and S. houskai (Balthasar, 1953). The current number of known taxa has therefore increased from 185 (179 species and 6 subspecies) to 315 (306 species + 9 subspecies). Hedychrum persicum Mocsáry, 1914 stat. nov. is upgraded to species rank. Chrysis chrysophora Semenow, 1892 and Hedychrum cyaneum Brullé, 1846 are considered nomina dubia and the latter as incertae sedis. Chrysis dawahi Strumia, 2012 is considered nomen nudum. The majority of chrysidid species in Iran (77.64%) are found exclusively in the Western Palearctic region. Among these, 21% are restricted to the Western Palaearctic. A thorough discussion is also provided on unreliable and doubtful species records.

An updated checklist of the hoverflies including distribution and seasonal occurence data of known species in Nepal is presented. The list is based on all available published literature on taxonomy, biodiversity, ecology, and biological aspects of the syrphid fauna of Nepal up to 2023. A total of 205 species from three subfamilies and 63 genera are known to occur in Nepal. Among the three subfamilies, Eristalinae shares maximum species (111 species, 54%), followed by Syrphinae (90 species, 44%), and Microdontinae (four species, 2%). is presented. Among these, 48 (23%) species are recorded in Nepal only. The distribution of known hoverfly species in the country is not uniform, with the Bagmati (82 species) and Koshi (75 species) provinces having the greatest number of species, while the Madhesh (four species) and Lumbini (one species) provinces having the lowest records. The highest number of species are recorded in May (51 species), followed by July (50 species) and June (48 species). Winter season records are relatively low, and distribution data are still incomplete for some sites. Based on the present review, comprehensive and systematic sampling across the entire country is necessary for further exploration of Nepal's hoverfly fauna.

In this research, a total of 19 aphid species belonging to 12 genera were collected on 20 host plant species. Furthermore, 33 associations between aphid species and host plants were recognized, of which six are new for Iran. Among the examined specimens, an Ovatus species collected on Mentha longifolia showed a complete range of intermediate biometric data of O. mentharius (van der Goot, 1913) and O. archangelskajae Kadyrbekov, 2008. In view of the biometric data from samples of Iran, we conclude that O. archangelskajae is a geographical variant of O. mentharius, therefore we consider it as a synonym for O. mentharius and redescribe O. mentharius as its morphological entities are extended. In this paper, the distribution of the aphid species in different parts of Iran is also presented and six new occurrences are reported for Fars and Kerman provinces. An identification key to the apterous viviparous female aphids living on Lamiaceae in Iran is provided.

سپردار زردشرقی مرکبات Aonidiella orientalis یکی از مهم ترین آفات مرکبات در جنوب کرمان است. پژوهش حاضر در زمینه نوسانات جمعیت و پراکنش فضایی این آفت در جنوب کرمان انجام شد. نمونه برداری از برگ، میوه و شاخه و روی پوره سن یک و حشرات کامل انجام گردید و شاخص های پراکنش تیلور، آیوائو، موریستا و Id، تغییرات نسبی RV و تعداد نمونه مطلوب محاسبه شدند. طبق نتایج، فعالیت این آفت از اواخر اسفند آغاز شده است. اوج جمعیت آفت در اواسط فروردین، اواسط اردیبهشت و اواخر شهریور ماه ثبت شد. پراکنش فضایی پوره سن یک بر اساس شاخص های تیلور و آیوائو در روش نمونه برداری از برگ و میوه، تصادفی تعیین شد. برای حشرات کامل طبق شاخص تیلور و آیوائو در نمونه برداری از برگ و میوه تجمعی بود. همچنین پراکنش براساس شاخص تیلور و آیوائو برای پوره سن یک و حشره کامل روی شاخه یکنواخت و تصادفی به ترتیب بود. مقادیر R2 در شاخص آیوائو نسبت به تیلور بالاتر بود و لذا از ضرایب شاخص آیوائو برای تعیین نوع توزیع فضایی و تعداد نمونه مناسب استفاده شد. تعداد نمونه مناسب برای پوره سن یک در روش های نمونه برداری از برگ، میوه و شاخه با دقت 25/0 به ترتیب 61/24، 29/24 و 2/19 محاسبه گردید. در هر سه روش نمونه برداری مقدار تغییرات نسبی RV برای پوره سن یک نزدیک 25 و برای حشره کامل نزدیک 10 محاسبه شد. براساس نتایج کلی در برنامه های مدیریت آفت می توان نمونه برداری را روی مرحله پوره سن یک و برای مطالعات اکولوژیک روی حشره کامل انجام داد.کلید واژگان: آفات مرکبات, نوسانات جمعیت, روش های نمونه برداری, پراکنشAonidiella orientalis is one of the most important citrus pests in the south of Kerman. Population fluctuations and spatial distribution of A. orientalis were studied in the south of Kerman Sampling was done from stages of nymphs (1st instar) and adults on leaves, fruits, and brunches during 2020-2022. The parameters of Taylor’s, Iwao, Morista, and Id power law, RV, and number of optimum samples (at two precision levels of 0.1 and 0.25) were calculated. Results showed that the pest activity started in mid-March and increased gradually, depending on weather conditions. The peak of population happened in mid-April, mid-May, and late September. The spatial distribution of 1st instar nymphs on leaves and fruits was random based on the Taylor and Iwao index, (b= 0.918 and 0.989 respectively) and it was Aggregative for adults (b= 1.8, 1.5 respectively). Moreover, both nymphs (1st instar) and adults had uniform and random distribution in the sampling of branches (b= 0.56-0.71) respectively according to the Taylor and Iwao index. As R2 values of the Iwao index were higher than Taylor, 's therefore, Iwao index was used for estimating the spatial distribution and appropriate samples. The number of optimum samples for nymphs (1st instar) on leaf, fruit, and branch sampling methods were estimated as 24.61, 24.29, and 19.2, respectively with 0.25 accuracy. In three sampling methods, RV was close to 25 and 10 for nymphs (1st instar) and adults respectively. Overall, in pest management programs sampling can be done on nymphs and for ecological studies on adults.Keywords: Citrus Pest, Population Changes, Sampling Method, Distribution

کرم قوزه گلرنک، Heliothis peltigera (Denis & Schiffermüller)، یکی از آفات کشاورزی شناخته شده در دنیا و ایران است که به برخی از گیاهان مهم اقتصادی خسارت وارد می کند. در این تحقیق به کمک نرم افزارهای MaxEnt، R و ArcGIS، مناطق مناسب برای انتشار بالقوه این آفت در ایران بر مبنای متغیرهای اقلیمی و داده های مربوط به حضور گونه پیش بینی و مهم ترین عوامل اقلیمی تاثیرگذار مورد بررسی قرار گرفتند. نتایج نشان داد که دو استان گیلان و مازندران، بیشتر نواحی استان بوشهر، جنوب استان هرمزگان و غرب استانهای آذربایجان غربی، کردستان و کرمانشاه مناسب ترین شرایط را برای استقرار این گونه دارند. علاوه براین، عواملی چون بارش در مرطوب ترین سه ماه سال (bio16)، سرعت متوسط باد در شهریور ماه (wind8) و اردیبهشت ماه (wind5)، و نسبت میانگین دمای روز به محدوده دمای سالیانه (bio3)، بیشترین تاثیر را در انتشار گونه ها دارند. بدیهی است، پیش بینی توزیع این آفت در مناطقی که میزبان های اصلی آن در آن جا سطح کشت بالایی دارند، می تواند در توسعه استراتژی های کنترلی آفت حایز اهمیت باشد.

In this paper, suitable areas for the potential distribution of this species in Iran were predicted using MaxEnt model, R package and ArcGIS based on its occurrence data and the bioclimatic factors. Moreover, the important climatic factors affecting their potential distribution were investigated. Based on the results of this study, the most suitable areas for this species are Gilan and Mazandaran Provinces. Additionally, most parts of the Bushehr Province and southern parts of the Hormozgan Province as well as western parts of the West Azarbaijan, Kordestan and Kermanshah Provinces have suitable conditions compared with the other areas. The main environmental variables contributing their distribution were precipitation of the wettest quarter (bio16), average wind speed in August (wind8) and May (wind5), and isothermality (bio2/bio7) (bio3). Predicting the distribution of this pest in the areas with high cultivation of its main hosts, can be important in the development of pest control strategies, obviously.

This paper is a part of a long-term study on the Noctuidae fauna of Kerman province. Here we report the newly identified species, which were collected mostly in the South of this province during the years 2015 and 2016. Totally, here we report 30 Noctuidae taxa from 13 genera and six subfamilies namely: Acronictinae (five taxa), Amphipyrinae (three taxa), Heliothinae (two taxa), Condicinae (two taxa), Bryophilinae (six taxa) and Noctuinae (12 taxa). Among these reports there are 12 new provincial records from Kerman. Amphipyra kitti Gaal-Haszler, Lödl, Ronkay, Ronkay & Varga, is recorded here as a new species for the fauna of Iran. Material examined is listed together with provincial distribution for each taxon. Wing pattern and male and female genitalia structures of A. kitti illustrated here. The female genitalia of this species describe here for the first time. According to this data, we concluded that despite the vast area of Kerman province, its fauna has been less explored compared to some of its neighboring provinces. We suggest to explore especially higher altitudes of this province.
