Abstract

This study on the insect pests of bottle gourd Lagenaria siceraria grown in polyhouse revealed the incidence of whitefly Trialeurodes vaporariorum and melon aphid Aphis gossipii from 26th to 38th standard week (SW). The peaks in incidence were observed in 34th SW (T. vaporariorum- 12.99 ± 1.18/ leaf and A. gossypii- 52.5 ± 9.60/ leaf. The incidence of these exhibited a positive correlation with temperature and a negative one with relative humidity. When insecticides were evaluated against these in polyhouse, after two sprays, imidacloprid 17.8SL (0.45 ml) was superior. Imidacloprid 17.8SL (0.3 ml) and dimethoate 30EC (1 ml) provided efficient control.
