Perspectives of non-phytoseiid predators for the biological control of plant pests

摘要: Non-phytoseiid mites of potential importance in the biocontrol plant pests include a dozen families. The host constitutes universe which and predators interact; thus growth pattern, leaf structure various available nutrients may affect control mites. role infochemicals prey finding by non-phytoseiids probably differs among Prey size be important success when predaceous feed on insect pests. Interactions between phytoseiids members other families hinder or complement pest control. Little is known effects plant-protection chemicals non-phytoseiid predators, but they appear to quite variable. Current research onHemisarcoptes, parasite armored scale insects, reviewed, including successful introduction into New Zealand. Active mite slicing shields deutonymph interactions with its vector-beetle are aspects predator's effectiveness. Further should include: collecting (with emphasis tropics subtropics), describing testing additional species against more pests; assaying pesticide effects; studying different families, especially uncultivated plants; trying nematodes, diseases weeds.
