بررسی کارایی سه نوع از تله های چسبی زرد رنگ در کاهش جمعیت پسیل پسته و ارزیابی امکان کاربرد آنها در روشهای تلفیقی در باغها پسته

Common pistachio psyllid (Agonoscena pistaciae Bur. & Lau.) is one of The most important pest on pistachio in Iran. Gardeners used to applied chemical method for controlling this pest. In this study using of yellow sticky traps on pistachio trees to reduce population of this pest was studied. This study contains of two basic surveys in Rfsanjan and a survey in Damgban. In the first survey the effects of yellow sticky traps on pest population was studied. And in the second survey the possibility of using of those traps near spraying chemical poisons in an integrated program were evaluated and comprised with control treatment and only trapping method. In Those surveys 4 treatments of yellow sticky traps contains 4, 8, 12 yellow card (10 x 20 cm) on each tree, yellow bands (5 cm width) alongside the rows and control (no trapping) were applied. Statistical comparisons in first survey showed that the control treatment significantly has the highest and "12 card" treatment, has the lowest infection to psylla nymph and other treatments were in the medium group. The population of psylla egg on "12 card" and "8 card" treatments were lower than other treatments. Therefore "12 card" treatment caused the highest reduction of the number of nymph and egg on pistachio leaves and "8 card" treatment was in the second step. Statistical comparisonS between 2 controlling methods in second survey were shown that there is a significant difference between those 2 methods. The results showed that the population of pest on trees with integrated method is very lower than it on only trapping method. it seems that this reduction of pest population is because of spraying in that area. Comparisons among treatments in the orchards where integrated method was applied showed that they are same in the nymph population. But the number of egg psyllid in. "4 card" treatment has higher than control and trapping treatments. Those results showed that trapping after spraying has not more effect to reduce pest population in comprise of only spraying. The results in Dmghan survey were shown that although sooner trapping in late winter in comprised of early spring, caused significantly more reductiDn of pest population but this reduction is not high. Therefore it is better that we start trapping in late winter and it is possible to start from late winter to early spring. The results showed that beside adult. pistachio psyllid some insects like Dipteras, lace wings, wasps, beetles, grasshoppers and other insect might stick on the traps.
