Here is the answer,
Insects are responsible for two major kinds of damage to growing crops. First is direct injury done to the plantby the feeding insect, which eats leaves or burrows in stems, fruit, or roots. There are hundreds of pestspecies of this type, both in larvae and adults, among orthopterans, homopterans, heteropterans, coleopterans, lepidopterans, and dipterans. The second type is indirect damage in which the insect itself does little or no harm but transmits a bacterial, viral, or fungal infection into a crop. Examples include the viral diseases of sugar beets and potatoes, carried from plant to plant by aphids.

Answer:
Crop damage is a major hazard to be treated and is regularly faced by farmers.
One of the major reason for the crop damage is leaf feeding insects.
These insects feed on the leaf lamina and make holes on the leaf such that the percentage of chloroplast and chlorophyll decreases hence the plant cannot perform photosynthesis show the occurrence or availability of food for plant decreases due to a decrease in photosynthesis and gradually yield of Crop decreases.
