List 10 agricultural pest in Nigeria

Insect pests are one of the main causes of loss of crop production in Nigeria and so pest management is very important all around the world.

The agricultural sector in Nigeria is one of the booming sectors in the country. This sector accounts for about 24% of the country’s gross domestic profit and it provides the country with enough income.

Agriculture is one of the leading sectors, so anything there is a drop in the production of crops, it is felt all around the country.

As individuals, it would be best to be educated on the kind of pests that affect agriculture in Nigeria and the kind of crops they infect. 

One of the major problems agricultural farmers face in Nigeria is dealing with pests and diseases. The country loses about 50% of its total crop production to the cost of damage by pests. 

The Nigerian government has proceeded to take plant health seriously because the source of the country’s food is in serious danger.

Also, the remaining yield that was not damaged by pests completely loses its quality and this also leads to an increase in food prices. 

What are agricultural pests?

Plants are constantly under attack. They face threats ranging from microscopic fungi and bacteria, small herbivores, like aphids, caterpillars, and grasshoppers, up to large herbivores, like tortoises, koalas, and elephants.

All are looking to devour plants to access the plentiful nutrients and water in their leaves, stems, fruits, and seeds.

But plants are ready with a whole series of internal and external defenses that make them a much less appealing meal, or even a deadly one.

But what are these pests?

What are crop pests

Any organism that is known to cause damage to animals, agricultural plants, people, and their goods economically can be referred to as a pest.

These organisms can be either a plant or an animal. Both crops in the shop and in the field are attacked by them. Direct damage or disease introduction may occur to crops as a result.

There are various types of crop pests; these crop pests can cause defoliation and necrosis of the leaf tissue if not managed.

Good ways to control crop pests

There are a number of good ways to control crop pests, ranging from cultural methods to chemical treatments. How does a natural ecosystem control agricultural pests? Here are some of the most common methods:

  • Crop rotation: As pests frequently have a predisposition for particular plants, this entails planting various crops in a single field each year.
  • Biological control: To manage pest populations, this strategy makes use of organic predators, parasites, or diseases. For example, ladybugs can be released to control aphids.
  • Chemical control: This involves using pesticides to kill or repel pests. However, this should be used carefully as it can harm beneficial insects, and can also lead to pesticide resistance.
  • Physical barriers: This is the use of physical barriers like nets or fences to prevent pests from accessing crops.
  • Integrated Pest Management (IPM): In a coordinated and sustainable manner, this holistic strategy incorporates several pest control techniques.

Ultimately, the most effective pest control methods will depend on the specific pest and the crop being grown. It’s important to consult with agricultural experts to determine the best approach for a given situation.

Beetles are one pest that is very common on Nigerian farmlands and they cause considerable damage to farm crops.

They cause damage to crops by chewing holes into plant parts. Beetles feed and lay eggs on crops and then keep feeding.

It can be gotten rid of by poisoning grains and leaving them in wait for the rate or setting traps around the farmland. 

Crops they attack – Wheat, sorghum, rice, groundnut, tuber crops, etc. 


Termites are tiny insects that travel in a pack and live in colonies like ants. They are silent insects and can feed on crops and woods without being detected. 

Some species of termite help to improve soil fertility and crop yield, but other forms cause major losses in farmlands. 

Crops they attack – Palm, camphor tree, cotton, sugarcane, millet, etc.
