Abstract
Management of Insect Pest Resistance of Transgenic Plant. Bahagiawati. Genetic
engineering with Bt genes is a powerful technology for protecting crops against insect pests. Crop cultivars carrying Bt genes, however, have some weaknesses, as many other insect control technologies, i.e. insect can evolve resistance to the genes, thereby eliminating their effectiveness. Insect pests have evolved resistance to all classes of widely used insecticides, including Bt products that were applied as sprays and to numerous crop varieties produced through conventional breeding program. The insect adaptation to resistant cultivars results in substantial costs to society, such as crop failures, environmental damages, and loss of useful products. For these reasons, there is a need to develop technologies that can manage problems on the insect pest resistances. This paper presents some cases where insect pests adapted to pesticides, resistant cultivars, and Bt-sprays. In addition, the mechanism of resistance and the inheritance of resistant genes in the insects are discussed. Some research strategies and implementation programs are also proposed and discussed in this paper.
