Cabbage (Brassicae oleracea var. capitata Linn.) is one of the most important and extensively cultivated vegetable crop because of its nutritional and economical values for producers and consumer point of view, respectively. The crop is prone for infestation by a number of insect pests consisting sucking and defoliating insects starting from germination to harvesting stage of the crop. In India, the diamond back moth, Plutella xylostella Linneaus and cabbage butterfly, Pieris brassicae Linneaus are the major Lepidopterous pests of cabbage. Adjusting planting dates can sometimes help to avoid certain insect infestations and reduce the need for chemical control. Planting dates influence the crop performance due to changed biotic and abiotic factors. The time of planting of cabbage, which is a season bound crop, has profound effect on the incidence of diamond back moth and cabbage butterfly. Several insecticides have been recommended through ages to avert pest damage, but some broad-spectrum synthetic organic insecticides and biopesticides are effective for the control of these two Lepidopterous pests.
