| Abstract: |
| Grape leafhopper, Arboridia kermanshah Dlabola (Hemiptera: Cicadellidae), is one of the most important pests of grapes, Vitis vinifera L., in Iran. Adults and nymphs are located behind the grape leaves and suck the cell contents of the mesophilic tissues. High population density of the pest usually causes economic damage. Application of pesticides to control this pest usually has unwanted and harmful effects on the environment, natural enemies and other useful animals. A survey was initiated to collect and identify parasitoid and predators of A. kermanshah in vineyards of Kermanshah region during two seasons of 2017-2018. Samples of infested leaves were collected weekly from vineyards. The insects and mites were studied via stereomicroscope in entomology laboratory of agricultural college in Razi University. Collected mites were clarified and mounted on slides containing Hoyer’s medium before identification. The leafhopper eggs in leaf tissues were marked. Then each infested egg on leaf tissue was transferred to petri dishes with wet cotton and kept in a germinator at 25°C and 60% RH, (14L: 10D) to allow parasitoids emergence. Petri dishes were monitored daily. Meanwhile, samples of predators were collected as feeding on the nymphs of the pest. Preliminary results proved that predatory mite, Anystis baccarum (Linnaeus, 1758) (Trombidiformes: Anystidae), and a lacewing larvae,Chrysoperla sp. (Neuroptera: Chrysopidae), fed on different nymphal stagrs of grape leafhopper. Moreover, parasitoid reared from leafhopper eggs were idenfied as Anagrus atomus (Linnaeus, 1767) (Hymenoptera: Mymaridae), Gonatocerus thyrides Debauche, 1948 (Hymenoptera: Mymaridae), Oligosita pallida Kryger, 1919 (Hymenoptera: Trichogrammatidae), Trichogramma sp. (Hymenoptera: Trichogrammatidae). Considering the importance of predators and parasitoids in reducing the number of grape leafhopper population, further efforts are needed to identify these biological agents in the future. Conservation of the biological agents can be considered as a safe and secure way to reduce leafhopper’s damages in vineyards. All identifications were managed by 3rd and 4th authors of the present study and samples were deposited in the insect collection of Razi University. |
