SYNERGISTIC ACTION OF SEED OILS ON THE TOXICITY OF INSECTICIDES TO Plutella xylostella (L.) (LEPIDOPTERA : YPONOMEUTIDAE)

G. V. SUNEEL KUMAR, V. T. SANNAVEERAPPANAVAR

Abstract


Diamondback moth (DBM), Plutella  xylostella (L.) (Lepidoptera : Yponomeutidae) is  the most destructive pest of crucifers, especially  cabbage and cauliflower. The pest is considered  to be a major constraint in the quality production  of cabbage and cauliflower in heavily infested  areas. Commercial considerations, however, have  compelled the cultivators to go for frequent  applications of “cocktails” of insecticides to get  blemish free heads, which fetch premium price in  the market. This practice of indiscriminate misuse  of insecticides has resulted in the development of  insecticide resistance in DBM in several vegetable  growing areas (Saxena et, al., 1989; Chawla and  Joia, i992).
