Abstract

An experiment on Life parameters of cabbage butterfly Pieris brassicae L. on ten cauliflower genotypes i.e, Snow mystique, White magic, Sydney,White corona, Local, Snow grece, Clima, 5340, Snow crown and AX-2034 was conducted at Entomology section ARI Tarnab Peshawar under field condition. P. brassicae eggs were marked on cauliflower genotype and caged the whole plant in 2x2 sq feet iron cage. The results from the ten cauliflower genotypes showed that minimum period of larval development was observed on Clima (35 days), maximum larval mortality was (80%) on AX-2034, and weight of pupa was higher (0.45 g) on Snow mystique ,minimum pupal period was recorded on White magic (20.67days), Pupal mortality was (100%)  on White corona, 5340 and AX-2034 and  Female to male sex ratio was highest of 1:5 on Snow crown and White magic . Wing span of both female and male was highest on Snow grece i.e  71.20 mm and 66.64 mm respectively. These results might provide useful basic information for screening of resistant genotype of cauliflower against  P. brassicae under field conditions.
