Insects which destroy crops include aphids, white flies, termites, rice weevils, mealy bugs and many other kinds. The consequences of this destruction are very serious, and include the introduction of diseases to the crops.
The categories destructive insects fall under include boring, piercing and sucking, and biting and chewing insects. Examples of boring insects include termites, crickets and beetles. Piercing and sucking insects include aphids and capsids. Biting and chewing insects include the bean beetle and rice wheevils. Many of these insects have strong mandibles and/or mouth parts. Insects can make the crops more susceptible to diseases. They also cause the cost of production to rise when farmers have to pay for pest control. Employing at least two methods of pest control is the most cost-effective way to get rid of them.
