Habitat management to enhance biological control in cultivated crops is an increasingly common method of pest control in both annual and perennial cropping systems. Examples of this approach include use of windbreaks or hedge rows to prompt build-up of natural enemies around crop edges, planting of insectary seed mixes as cover crops in perennial crops, or management of natural ground cover (e.g., via mowing frequency, strip mowing, or selective herbicide use) to enhance build-up of natural enemies.
The following species are the most common predatory mites in Polish mushroom houses, in which Agaricus bisporus is cultivated: Arctoseius semiscissus, A. cetratus, Dendrolaelaps fallax (Kropczyfiska-Linkiewicz 1984), and Parasitus sp. (Lewandowski, unpubl.). Species composition of mite predators of mushroom houses with oyster mushroom (Pleurotus ostreatus) is not known yet. Predatory mites are obviously of the most interest in mushroom pest control in the organic mushroom houses.
The consumer demand for organic produce is increasing. In order for growers to be able to meet this demand, effective non-chemical tools need to be available for pest management. In BC in particular there is an increase in the production of organic cole crops, hence an urgent need to develop organic integrated pest management (IPM) systems that emphasize biological, cultural and other non-chemical methods (for insect and disease management).
The objective of this study was to examine the use of rove beetles, Aleochara spp., for the biological control of root maggots, Delia spp. in organic cole crops. We were interested in manipulating Aleochara numbers by either conservation strategies or by augmentative releases of mass-reared Aleochara bilineata.

Determing habitat requirements for natural enemies of farm pests

Maintaining a healthy population of beneficial insects that serve as natural enemies to crop pests is an important component of pest management for organic farmers. To do so, we must understand the habitat requirements of these insects.
