Host plant resistance as a method of insect pest control in the context of IPM has a great potential than any other method of pest suppression. The use of insect resistant cultivars improves the efficiency of other pest management practices, including the synthetic insecticides. In some cases, it is the only practical and effective method […]

The insects are exposed to the toxin proteins in transgenic crops throughout the feeding cycle and season, and as a result, the insect populations are under continuous selection pressure. As the toxins are expressed in all parts of the plant, there is a serious threat of rapid development of resistance in insect pests. Toxin production […]
Bases of Plant Resistance to Insect Pests | Pest Management
Article shared by :
A number of plant characteristics are known to render the cultivars less suitable or unsuitable for feeding, oviposition and development of insect pests. Broadly, these characteristics can be classified into two categories, i.e., biophysical and biochemical. 1. Biophysical Bases: The plant resistance is controlled by several morphological factors like remote factors, e.g., colour, shape, size, […]
