[Determination of parasitism status of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) on greenhouse and field grown cultural plants in Balcali (Adana)]
Turkish Journal of Entomology 30 (2), 113-121
Abstract: In this study population development of Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) and apparent parasitism by aphelinid parasitoids were determined on greenhouse-grown tomato (Lycopersicon esculentum Miller) in 2004, eggplant (Solanum melongena L.) and cucumber (Cucumis satlvus L.) in 2005 and on field-grown melon (Cucumis melo L.), in 2004-2005 in Balcali (Adana).
Eretmocerus mundus Mercet and Encarsia lutea (Masi) (Hymenoptera: Aphelinidae) were found to be important parasitoids of B. tabaci on all surveyed plants. The weekly percent parasitism rates of Er. mundus varied between 49.7 and 76.7 %, but the highest was found on cucumber plants. These values varied between 5.1 and 25.9 % for En. lutea. Therefore, Er. mundus was found to be more effective than En. lutea on all examined plants. Total percent parasitism rates of B. tabaci on tomato, eggplant and cucumber were found to be 93.2, 83.4 and 64.0 % respectively, during the growing season in the greenhouse. These values were 58.0 and 67.6 % on field-grown melon for the first and second year, respectively. B. tabaci populations on tomato and eggplant reached high levels whereas on cucumber and melon were always low and never reached levels that cause economic loses. As a conclusion both parasitoids were found promising candidate on biological control of B. tabaci.
