Abstract

:Trapping efficiency of seven different colored sticky traps (Green, Fluorescent yellow, Orange, Pink, Red, White and Yellow) was evaluated in some Solanaceae plants, tomatoes (Lycopersicon esculentum, eggplant (Solanum melongena) and sweet pepper (Capsicum spp.) crops, for whitefly (Bemisia argentifolii), leafminers (Liriomyza trifolii, thrips (Thrips tabaci) in Riyadh, Saudi Arabia. The traps were placed at four different heights (0.5, 1.0, 1.5 and 2.0 m above the ground). The experiment was laid out in a Completely Randomized Block Design (CRBD) with four replications during Autumn 2001, Spring and Autumn 2002. Significantly high insect populations were trapped on fluorescent yellow, yellow and green colored sticky traps. No significant differences were witnessed between mean number of various insects caught on sticky traps placed at different heights but more insects were trapped at 0.5-1.5m.
