Abstract
In agriculture the Bacillus thuringensis as insecticidal toxins have been used for insect pest management
for decades. The specific molecular interaction between the toxin and the insect midgut receptors makes
the Bt a popular choice for pest control. This specificity of the action of Bt toxins reduce the concern of
adverse effect on the non-target species, a concern which remains with the chemical insecticides since
centuries. Different class of toxins are produced by Bt and to maximise the effect the diferent toxins are
often combined which makes the Bt expression in then transgenic more effective. Although, the Bt is
very effective, but there are concerns over the resistance development by insects species and also the
narrow spectrum of activities of individual toxins. Gene flow, cross- resistance and hazards to the
environment are of major concern in developed countries. Research is in progress to improve the toxicity
of the Bt-toxins so as to control the resiatnce development. Therefore the aim of present revive is to
explain the genetic engineering of the plants for insect control, disadvantages and strategies for the
continuous research, development and improvement of Bt and non-Bt resistance products to tackle the
insect pests problems without any harmful impact on the environment.
