The efficacy of some traps in attracting and capturing olive fruit fly, Bacterocera oleae (Diptera: Tephritidae) and non-target insects in Roudbar region of Iran

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.
