Some biological characteristics of eggs contaminated by licensed drugs for sunn pest (Eurygaster integriceps Put. Het.: Scutelleridae) and some biological characteristics of Trissolcus semistriatus Nees (Hym.:Scelionidae)

In this study, Sunnpest, Eurygaster spp. (Heteroptera: Scutelleridae) which is widely used for synthetic pyrethroit insecticides Cypermethrin, Alpha-cypermethrin, Lambda-cyhalothrin and Deltamethrin effective substances in the formulations of insecticides EC formulation of Trissolcus semistriatus Nees (Hymenoptera: Scelionidae) was investigated. As a result of application of these insecticides by spraying and dipping method before and after parasites on sunflower eggs, the effects of egg parasitoid on adult growth and biological activities were determined in 2019. As a result of the study, the effect of insecticides used in the control of the sunflower and the contaminated Sunnpest eggs on the survival (%9-31) and parasitic strength (%7-29) of T. semistriatus adults %0-30 was classified as harmless or less harmful in the N class value. Insecticides were classified as moderately harmful with an M class value of %50-76 effect on pre-adult T. semistriatus. The parasitoids in the parasitic Sunnpest eggs applied by insecticide spraying and dipping were found to continue to develop in both conditions. Deaths from parasitoids are thought to occur as a result of contact with the eggshell while hatching.
