Dried figs have suffered significant damage in the last decade due to the activity of African fig fly (Zaprionus indianus). In this research, it has been tried to study different attractants for use in traps for mass trapping and non-chemical control of this pest. The experiment was conducted as a factorial experiment in a randomized complete block design with ten treatments and in three replications in one of the infected rainfed fig gardens of Kazeroon. Experimental treatments included four liquid adsorbent compounds including pure apple cider vinegar, hydrolysis protein 3%, pomegranate sauce 3% and fig juice 50% in two forms of solution and gel (using superabsorbent powder (polyacrylamide)) and two solid attracting, mashed banana fruit with yeast powder and banana slice with yeast powder and superabsorbent powder (Polyacrylamide) were used. The results showed that there were significant differences between the various treatments at less than 1%. The combination of crushed banana fruit with yeast powder with an average weekly attracting of 87.44 had the highest attraction of African fig flies and was alone in one group. After this combination, banana slice with yeast and superabsorbent, pomegranate sauce 3% with super absorbent (gel form) and pure apple cider vinegar with an average weekly absorption of 76, 50 and 42.31 per week of African fig flies compared to other compounds attractants were more efficient. The results also showed that the use of superabsorbent powder with liquid attracting compounds can increase shelf life of traps and reduce the cost of trapping.

Management of the olive fruit fly using environmentally friendly methods includes strategies based on lure and kill and/or mass-trapping to reduce the damage to fruits. The purpose of this study was to evaluate the efficiency of some attractive materials to lure and capture olive fruit fly. Four trials and eight replications were conducted in an olive grove in Roudbar, Iran in 2016 and 2017. The treatments were: 1) yellow sticky trap, 2) yellow sticky trap + Pheromone, 3) Mcphail + Protein hydrolyzate, 4) Mcphail + Propylene vanilla based solution. Traps were visited weekly and the data were analyzed using SAS software. The results of the first year (2016) showed that treatment 4 with other treatments had a significant difference in terms of attracting male and female insects, and treatment 1 had the highest non-target insects attracted with an average of 38.8 ± 25.8. In the second year, treatment 2, total male and females and male insects captured were significantly different with other treatments, but non-target insects with an average of 68.55 ± 7.23 and treatment 1 with a mean of 77. 58± 9.16 were at the same statistical level and treatment 4 with an average of 0.96 ± 0.27 had the highest incidence of female insects. Treatment 4 had the highest mean in attracting female insects and the lowest number of non-target insects in the two years of study. This trend was the same in two years of study in terms of mean number of insects captured per week in different treatments. As a whole, it had no adverse effects on the bio-diversity of olive groves and lowest price in comparison with other treatments. It can be concluded that this treatment along with pheromone traps can be used in monitoring and control of the pest.

The African fig fly has been reported from Iran in 2009. The use of chemical insecticides has several environmental limits therefor the efficiency of some attractants has been evaluated for trapping of this insect in Iran. A field experiment was conducted in Completely Randomized Factorial Design with four replicates to determine the best attractant for trapping and the best height for installing traps on trees in Shiraz city, in 2009. The first factor was attractants including: Solution of pomegranate sauce 3 % (3% pomegranate sauce%water), Solution of hydrolyzed plant protein 3% (3% hydrolyzed plant protein %water) and Ceratrap. The second factor was height for installing traps on trees including: 75, 150 and 225cm. Results revealed significant differences among the attractants and height for installing traps in all weeks except 13th week and also the interaction effect between them. The evaluation showed that the best attractant for capture was solution of pomegranate sauce 3 % with significant difference from the others. Evolution about the best height for installing traps showed that 150 cm height for installing traps was better than the others. So traps with solution of pomegranate sauce 3 % that installs on trees at a height of 150 cm could have an important role to decrease the population of this pest and it is an approach in order to non-chemical control.

The Mediterranean fruit fly is a quarantine pest which was seen in Fars province, Iran in 2008. Pomegranate is one of the hosts of this pest in the late season, Two different methods, including trapping and bait spraying, were used in order to evaluate populalim suppression in shiraz in 2011 and 2012. Through trapping method, three attractants includeing Trimedlure, Biolure, Femilure, were investigated separately in a Tephri traps with three replications, in this way, the average number of infected fruits (with control) and also the number of trapped Mediterranean fruit flies (without control) were bait spraying method,Two types of hydrolyzed proteinin and smell bal were used the south side of the trees, In bouiting method, two types of hydrolyzed protein, Bioceboand Smelltol were sprayed mixed with 0.002 concewtratin of malathion on trunks and one meter width of south part of the tree crown Trimedlure and biolure had the same effect on number of infected fruits, but more effective than the control and Femilure. Howerer, the number offlies couptured was higher in Bcolure. In baiting method, no significant difference was observed among the treatments , howeres the place on the trees was significantly different .Number of infected fruits was less in one meter width spraying on the crown.
