The whitefly, Bemisia tabaci is a key insect pest in Solanum vegetables such as tomato, chili, pepper and eggplant. Improper and overuse of insecticides often result in outbreak of whitefly infestation, and in turn bring the plant virus and honeydew associated quality problems (Fig. 1).

During the last crop season in Gao’an, Jiangxi province of China, the EUCLID partner ZJU used the combining methods of 60-mesh insect-proof net, yellow sticky trap, rotation of pesticides, and natural enemy, Encarsia formosa for the control of B. tabaci in chili (Figs. 2-3). A successful reduction of insecticides usage up to 50% was obtained.
