Impact of Various Brassica species on The Developmental Response of Pieris brassicae (Linnaeus) (Lepidoptera: Pieridae), Its Extent of Damage, And Report of Its Biocontrol Agent In District Rajouri of Pir Panjal Region of Himalaya

Cole crops are globally consumed as vegetables and important sources of our dietary requirements, but they infested by an array pests, specifically the large white butterfly, Pieris brassicae (L). It is a critical global pest cruciferous vegetable crops. We investigated consequences diverse on fitness P. under laboratory conditions in 2021-22, to survive, develop, reproduce conditions, extent damage, report biocontrol agent, Cotesia glomerata Under effect radish (Raphanus sativus), cabbage (Brassica oleracea var. capitata), cauliflower botrytis) health were assessed studying survival time, total development mortality. Development time from hatching eggs adult emergence was longest (32.6±0.84 days) shortest (25.0±1.41 days). In addition, higher percentage (96%), lower larval death, yield adults indicated fact being most appropriate food for brassicae. Life tables dominant tools analyzing comprehending various aspects insect population's growth, survival, reproduction. Furthermore, crop loss function population information losses would serve guide research programmes improvement. The resistance certain insecticides methods used manage this products general required extensive including biocontrol. endoparasitoids C. (L) agent against district Rajouri which first record area which, therefore, warrants essentiality having compact management plan that can relieve dependency destructive chemical control methods.
