Abstract

The results revealed that peak activity of Plutella xylostella, Myzus persicae, Crocidolomia pavonana, and Spodoptera litura was recorded during 49th, 51st, 52nd and 1st SMW, respectively. The maximum population of natural enemies like Coccinella transversalis, Diaeretiella rapae, and Ischiodon scutellaris was observed during the 51st SMW. The weather parameters had a significant influence on Plutella xylostella, Crocidolomia pavonana, Spodoptera litura, Coccinella transversalis, and Diaeretiella rapae populations. However, there was no significant effect observed on the population of Myzus persicae and Ischiodon scutellaris.
