The large white butterfly, Pieris brassicae (L.) is an important pest of both vegetable and oilseed Brassica crops. The present pest management methods rely largely on the use of synthetic chemical pesticides posing serious health hazards in additionto environment pollution. Host plant resistance is an important alternate pest management strategy. However, development of an insect resistant cultivar requires the identification of resistant source. In this study, we have attempted to evaluate some wild crucifers both under field and laboratory conditions. Atotal of 14 wild crucifers from six species along with two cultivated varieties from two species were evaluated. Based on the two years of field screening and laboratory evaluation, it was found that eight genotypes from four species namely Sinapis alba: CN-33054, Diplotaxis muralis: WS-09-72, D. tenuifolia: WS-09-78, WS-09-81, Brassica tournifortir. WS-09-71, ATC-94485, ATC-94725 and ATC-94777 were promising as these exhibited significant adverse effect on the biology of the pest.
