Pests Of Stored Feed And Their Control

Gbogbo ọrọ náà

A poultry keeper in Sokoto opens a sack of maize bran two months after buying it and finds the feed clumped together with silk webbing, small moths flying up as she loosens the mouth of the sack, and a corner of the sack gnawed clean through overnight. The bran she paid good money for is now partly dust, partly moth silk, partly rat droppings. Every farmer who stores feed for even a few weeks meets these same three enemies: weevils, rodents and moths, and every one of them can be beaten with methods a WAEC candidate is expected to know by name.

In this lesson you will learn to recognise each pest from the damage it leaves behind, so that a torn sack, a bored grain and a web of silk each point straight to their culprit. You will then learn the non-chemical and chemical methods used to control them, and the precautions that keep a chemical treatment safe for the animals that eventually eat the feed and the person who applies it.

  1. Identify common pests of stored animal feed
  2. Explain the damage caused by pests to stored feed
  3. State the methods of controlling pests of stored feed
  4. Explain the precautions taken when applying chemical control methods
  5. Distinguish between chemical and non-chemical methods of pest control

Akọmọ Ojú-ẹkọ

Feed is usually the single largest cost of keeping livestock, often more than half of it. Feed that is bought, transported and paid for, then left in a store for weeks before it is fed out, is under constant attack from three kinds of pests. Left unchecked, a bag of maize can lose a fifth of its weight to insects alone, and a bag gnawed open by rats can be finished within days. A farmer who cannot name the pest cannot choose the right control, and a farmer who chooses the wrong control can do more harm than the pest itself, for example by feeding animals grain still carrying a poison meant to kill rats. This topic teaches both halves of that skill together.
