Abstract

Cucumber is a creeper vine vegetable. It belongs to the Cucurbitaceae family that bears cucumiform fruits, which are used as vegetables. There are three main varieties i.e., slicing, pickling, and burpless or seedless. This study was conducted at Millan Agro Seed, Agricultural Research Farm, Tandojam to observe the efficacy of various insecticides against insect pests of cucumber i.e., Bemisia tabaci (Gennadius) and Aphis gossypii (Glover) in greenhouse at different days intervals. The maximum reduction in B. tabaci population was recorded as 96.36% by Imidacloprid and Dimethoate, respectively; followed by Acetamiprid (91.95%), Bifenthrin (91.76%), and Cypermethrin (60.73%) at 7 DAS. Similarly, the population of A. gossypii was reduced to 98.46% by Dimethoate followed by Acetamiprid (94.66%), Bifenthrin (91.76%), Imidacloprid (91.67%), and Cypermethrin (41.76%) on the same day (7 DAS), respectively. The ANOVA indicates a significant difference (P<0.05) between various insecticides and day intervals. However, LSD showed a non-significant (P<0.05) difference between Imidacloprid and Dimethoate against B. tabaci and Imidacloprid and Bifenthrin against A. gossypii, respectively. It is concluded that the high population reduction of B. tabaci was observed after the application of Imidacloprid and Dimethoate insecticides at 7 DAS. Therefore, Acetamiprid and Bifenthrin insecticides were also displayed a significant reduction against the whitefly population. Similarly, the maximum reduction % of A. gossypii was showed after the spray of Dimethoate insecticide followed by Acetamiprid, Bifenthrin, and Imidacloprid insecticides on 7 DAS, respectively. The lowest reduction of B. tabaci and A. gossypii was seen on Cypermethrin insecticide on the same day.
