Description of practice

Biological pest control is a method of controlling pests (such as insects, mites, weeds and plant diseases) using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.

Examples of how to use biological pest control Further information
(see Note below)

AMP76 01

Importation of natural predators

A pest’s natural enemies (e.g. beetles or larvae) are introduced to a new locale. It is important to note that this kind of introduction may have additional consequences.

AMP76 02

Improve habitat for native fauna

Pests can be controlled and combatted by improving the habitat for fauna, thus attracting native predators, parasites or herbivores. Active management is required to (re-) establish and maintain the native fauna.

AMP76 03

Inductive augmentation

Natural predators (e.g. ladybirds) of a particular pest (e.g. aphids) are released to augment the predator population in an area.

AMP76 04


Hoverflies (syrphids) are used as a biological pest control. In their larval stage hoverflies are capable of consuming vast amounts of small-soft-bodied insects daily.

AMP76 05

Green lacewings

After they have hatched, the larvae of Green lacewings are distributed by sprinkling. They feed on aphids, small worms, eggs, mites and thrips.

Beneficial nematodes

Beneficial nematodes (such as the Heterorhabditis bacteriophora) are applied to control different beetle larvae in the soil. The nematodes use the larvae as hosts, killing them in the process.

AMP76 07

Push-Pull integrated pest management

In an area affected by stemborer moths, maize is intercropped with a repellent “push” plant (e.g. desmodium). The plot is surrounded by an “pull” plant (e.g. napier grass), attractive to the moths but which secretes a sticky substance trapping their larvae.
