An insect pest can simply be defined as any insect capable of causing damage to crop plant.
It is important to state that we have other organisms that aren't insects (insect pests) but are also capable of causing damage to crop plants. Such organisms include:
Our classification of insect pest will be based on their mode of feeding. These group of insect pests will include:
A major characteristic of the biting and chewing insect pest is the possession of mouth-parts such as a strong mandible and maxillae.
The image below shows the mouth parts of a biting and chewing insect:
Note: The mandibles and maxilla of insect pests are used for biting and chewing plant parts.
Examples of biting and chewing insects include grasshoppers, termites, army worms, locust, beetles, leaf worms and so on.
Piercing and sucking insects possess a strong mouth part called proboscis.
The proboscis is a tiny and elongated mouth-part which enables certain insects to pierce through plants in order to suck the liquid substances from their tissues.
The image below shows the proboscis of a piercing and sucking insect:
Examples of piercing and sucking insects include aphids, cotton strainers, butterflies, mealy-bugs and white flies.
Boring insects will bore or make holes into crop plants. They end up destroying the tissues of plants, fruits and seeds through this process.
Examples of boring insects are stem borers, bean beetles and weevils.
Below are some of the economic importance or effects of insect pest in crop production:
