Time specific threshold in activity of Coccinella septempunctata in mustard field
The parasitoids and predators are generally free-living in their adult stages and visit the crop at specific time in a day.Therefore, avoiding chemical application in this duration reduces the chances of direct exposure of natural enemies to the pesticides. The present work demonstrates the timed peaks in Coccinella septempunctata captures under field condition. The threshold in captures was noticed in morning and evening hours while least number of individuals were noticed during mid day on the mustard crop.
