NY229 - Evaluation of Indigenous Biological Control Agents for Thrips and Broad Mite on Ornamentals

This 1992-95 study confirmed indigenous predacious mites may attack many local and introduced pest species of ornamentals. It recommends the predators discovered in the study and code-named species A, B and C for commercial-in-confidence reasons, be further investigated. The study also suggests the Verticillium lecanii fungal disease associated with Broadmite and aphids may be developed into a potential biological control method. It recommends trials be conducted to determine whether indigenous predators are starting to evolve resistance to pesticides.
