The first DBM resistance was reported on dichlorodiphenyltrichloroethane (DDT), from then it has developed resistance to other insecticides. Its ability to build resistance to almost every insecticide introduced is a great concern to the agriculture world, owing mainly to its short life cycle, continuous host availability and its genetic elasticity. Numerous resistance mechanisms displayed by DBM to counterattack effect of insecticides, either behaviorally, physiology or by biochemical. This paper is focused on diamondback moth (DBM) resistance to insecticides, its biochemical mechanism and the potential to become cross resistance to other insecticides. We highlighted the biochemical reactions in DBM resistance and emphasized on enzymes responsible to the resistance. The information on the mechanism could provide valuable information to other researchers in designing a rapid and sensitive biochemical assay in detecting DBM resistance to many insecticides that has yet to be discovered. The potential of DBM to develop cross resistance to other insecticides is also stressed since the issue is always co- related with biochemical resistance mechanisms. Keywords: Biochemical resistance mechanisms; diamondback moth; resistance. ------------------------------------------------------------------------ * Corresponding author.
