Insect resistant crop plants form the core component of Integrated Pest Management (IPM) due to their ability reduce losses and associated insecticide costs in addition protecting environment. In this review, various types resistance being cited, mechanisms causal factors responsible with examples were discussed. Traits resistance, genetics inheritance patterns listed. Several sources including...

Insect pests are the major cause of damage to commercially important agricultural crops. The continuous application of synthetic pesticides resulted in severe insect resistance by plants. This causes irreversible damage to the environment. Bacillus thuringiensis (Bt) emerged as a valuable biological alternative in pest control. However, insect resistance against Bt has been reported in many cas...

Introduction Resistance is a natural phenomenon, a result of evolution and adaptation to environment. When a pest population is exposed to a pest management tool, whether chemical, biological, or cultural, the individuals in that population that are genetically predisposed to overcome the management tool are more likely to survive and pass their genes on to the next generation. Over multiple ge...

Utilization of native insect resistance genes can be an important component for managing insects in soybean [Glycine max (L.) Merr.]. A major quantitative trait locus (QTL-M) for insect resistance from PI 229358, controlling antibiosis and antixenosis, was previously identified on linkage group (LG) M and was found to increase the effectiveness of a Bacillus thuringiensis (Bt) transgene in soyb...

BACKGROUND The spread of insect-resistance transgenes from genetically engineered (GE) rice to its coexisting weedy rice (O. sativa f. spontanea) populations via gene flow creates a major concern for commercial GE rice cultivation. Transgene flow to weedy rice seems unavoidable. Therefore, characterization of potential fitness effect brought by the transgenes is essential to assess environmenta...

The past ten years have seen the elucidation of the molecular basis of insect resistance to many chemical insecticides. Target genes, mostly in the nervous system, have been identified and cloned from Drosophila melanogaster and resistance-associated mutations have been examined in a range of pest insects. More recently, with the advent of annotated insect genomes, resistance mediated by comple...

Pathogens are thought to exert strong selection on their hosts leading to increased host resistance. Bacillus thuringiensis kurstaki (Bkt) is a ubiquitous entomopathogen that has become the mainstay of nonchemical control of Lepidopteran pests and thus, the potential exists for the evolution of resistance in targeted host insects. We have studied the expression of Btk resistance in the cabbage ...
