Detailed explanation-1: -Generally, insect pests attack the plants in three ways: (i) they cut the root, stem, and leaf, (ii) they suck the cell sap from various parts of the plant, and (iii) they bore into stem and fruits. They thus affect the health of the crop and reduce yields.
Detailed explanation-2: -They act as predators and devour pests including greenflies and caterpillars. Wasps are good pollinators as well. Many flies act as pollinators too. Their larval stages are parasitoids of eggs and larva of other insects helping to keep the host species under control.
Detailed explanation-3: -(a) Loss of photosynthetic tissues; in extreme cases defoliation may result. (b) Destruction of buds and shoots. (c) Destruction of flowers, fruits and seeds. (d) Boring and tunnelling of stems; interruption of sap flow and physical weakening of the stem; stem breakage may result.
Detailed explanation-4: -An insect is a small animal that has six legs. Most insects have wings. Ants, flies, butterflies, and beetles are all insects.
