Natural enemies

Beneficial organisms in agricultural systems include natural enemies, pollinators and nutrient cyclers. Natural enemies play an important role in suppressing populations of many key pest species in grain crops.

Being able to identify the suite of natural enemies that are active in your crops is the first step in integrating them into your management decisions. The preservation of natural enemies, through the judicious and selective use of insecticides, is central to harnessing the contribution that they make to suppressing pest populations and, consequently, minimising crop loss.

This guide provides a snapshot of key natural enemies of pests commonly encountered in grain crops in the northern region. The photographs and identification information are designed to assist growers to include natural enemies in their day to day crop monitoring.
