Beneficial insects are an important tool to help combat insecticide resistance

Beneficial insects play a vital biological control role in many cropping systems and assist in keeping pest populations in check. Beneficial insects can be encouraged by better targeting and reducing insecticide applications, as well as providing alternate food sources and refuge habitat on farms. This guide is designed to assist growers identify some of the most commonly observed beneficial insects found across the southern grain cropping regions and provide information on each groups biology, pests attacked, and the toxicity of common chemical actives.
