Zoology - Strategies for Enhancement in Food Production Question with Solution | TestHub

Insect and pest infestation are one of the major causes of large-scale destruction of crop plants and its produce. Crops plants show insect resistance which can be due to morphological, biochemical or physiological characteristics. Hairy leaves in several plants are associated with resistance to insect pests, e.g, resistance to jassids in cotton and cereal leaf beetle in wheat. In wheat, solid stems lead to non preference by the stem sawfly and smooth leaved and nectar-less cotton varieties do not attract bollworms.
