Definition of Pests

Pests are organisms that carry disease or cause damage to other organisms. Pests may be plants or animals. Plant pests are usually called weeds. Pests are very important to man because of their detrimental effects to humans and other organisms of concern to man e.g. agriculture or livestock production.

Crop pests are those that affect agricultural produce important to man, e.g. insects, birds etc. Livestock pests attack livestock useful to man e.g. Mites, Lice, Tapeworms.

Pests usually decrease the quantity and quality of agricultural production, especially when present in large numbers.

Crop-Destroying Weevils

Weevils are among the most destructive of pests that attack agricultural crops. Adult weevils lay their eggs in stalks or seeds of crops such as cotton, wheat, rice, and alfalfa. As larvae, weevils then feed on these plant tissues, extensively damaging the plant in the process.
