Predatory arthropods are important in cotton IPM programs and planting a diverse range of crops may increase the on farm bio-diversity of predators. In some growing regions, it is common for large-scale cotton monoculture to be planted. Mixed cropping is likely to increase the bio-diversity and abundance of predators which may assist in increasing the natural control of pests. It is Important that the potential number of predators produced in different crop habitats is known. Specific crops can then be planted to enhance the numbers of key predatory species. Knowledge of the types of predators produced from different crops is important because some predator species are more significant natural enemies of pests than others. The research presented here provides information on the numbers and types of predators harbouring in a range of crops on a Darling Downs dryland cotton farm.
