Abstract: The diamondback moth (DBM), Plutella xylostella (L.) (Lep., Plutellidae), is one of the most destructive insect pests crucifers worldwide. It was first crop reported to be resistant DDT and now in many crucifer‐producing regions it has shown significant resistance almost every insecticide applied field including biopesticides such as crystal toxins from Bacillus thuringiensis spinosyns Saccharopolyspora spinosa . In certain parts world, economical production become impossible because its insecticides resulting control failure. A coordinated management program needs implemented with involvement pesticide industry, local regulatory authorities, scientists farmers. judicious use chemicals conjunction other measures (e.g. biological agents, varieties, proper fertilization rates) best way manage DBM cruciferous crops. Introduction glucosinolate‐sulphatase inhibitors plant‐incorporated‐products or sprayable material may also lead a novel pest strategy.
