Aphids suck sap from plants, weakening them and spreading diseases. These tiny insects reproduce rapidly, forming large colonies that can quickly damage various crops.

Stem borers, such as the corn borer, burrow into plant stems and roots. This weakens the plants and makes them susceptible to disease, drastically reducing crop productivity.

Caterpillars chew through leaves and stems, particularly those of moths and butterflies. They can defoliate entire plants, severely reducing crop yields and quality.

Beetles, like the Colorado potato beetle, consume leaves and stems of various crops. They are highly resistant to pesticides, making them difficult to control and manage.

Swarms of locusts can devastate crops, consuming their own weight in food daily. They travel in vast numbers, leaving fields barren and causing widespread food shortages.

Fly maggots, such as the cabbage maggot, burrow into roots and stems, causing plants to wilt and die. Their feeding habits can ruin entire fields of crops.

Moth larvae, like the armyworm, feed on a variety of crops, often stripping plants of leaves overnight. Their rapid spread and high reproductive rate make them formidable pests.

Thrips damage plants by sucking their sap and spreading viruses. They cause leaves to become deformed and discoloured, severely impacting crop growth and yield.

Weevils infest stored grains and seeds, reducing their quality and causing significant economic losses. They bore into the grains, making them unusable for consumption or planting.

Whiteflies feed on plant sap and excrete honeydew, leading to sooty mould growth. They also transmit plant viruses, causing extensive damage to various crops.
