Abstract
A set of experiments was carried out to investigate the population dynamics of important insect pests that infest capsicum, bottle gourd and cucumber. Results revealed that aphid (Aphis gossypii Glover), whitefly (Bemisia tabaci Genn.) and leafhopper (Amrasca biguttula), and commenced the activity during the second and third week of October and November. The mean thrips peak population find in the second and third week of October in chilly (6.90) whereas third week for bottle gourd as well as cucumber (8.88 and 9.67 respectively). The average white fly density maximum is seen between the second of October in chilly, bottle gourd and cucumber (6.19, 8.88 and 9.67 respectively). Leaf hopper population also heigh in second week of October (5.02, 5.76 and 5.65) for chilly, bottle gourd and cucumber.
