abstract
A survey was conducted to assess the diversity of different natural enemies. Insect specimens were collected from different ecosystems of Jorhat district during 2017- 2018. Collections of various natural enemies were made from various ecosystems and a total of 50 surveys were conducted during the study period. The study reveals that the area under the survey has natural enemies belonging to 8 orders, 16 families, 32 genera, and 40 species and their ecological roles span from predator to parasitoids. The order Coleopteran was dominant with (11 species) occupying the maximum number of species where Hymenopteran order with (10 species), followed by Araneae with (9 species), Odonata with (7 species), Diptera with (1 species), Lepidoptera with (1 species) and Mantodea with (1 species) counts only a few during the study. The presence of different natural enemies indicated that it has a good potential source for better cultivation and therefore required to study about the efficiency of some important predators and parasitoids.
