ability to survive in the soil for many years and are very difficult to control ( Bost, 2006 ; Bost et al., 2013 ). Biological control agents (BCAs) can be helpful in decreasing the soil inoculum potential of soilborne pathogens and therefore improve soil

inhabit the underside of leaves, they can go undetected until populations are already causing damage. Therefore, growers traditionally rely on preventative applications of miticides to avoid TSM problems. Biological control offers an alternative for
edible crops (24%) and non-edible crops (13.5%). In a separate study, consumers were willing to spend up to $485 annually for the protection of eucalyptus species in the landscape with biological control pest management practices from the eucalyptus snout
In recent years, the tomato russet mite (TRM) [Aculops lycopersici (Acarina: Eriophyidae)] has become one of the more important pests of greenhouse tomatoes in northeastern North America. As a first step toward developing a biological control strategy for the TRM, our objective has been to test the potential of already commercialized mite predators. In laboratory experiments, voracity of Chrysopa carnea (Neuroptera: Chrysopidae), Phytoseiulus persimilis (Acarina: Phytoseiidae), and Amblyseius cucumeris (Acarina: Phytoseiidae) was determined for egg, immature, and adult stages of the TRM. The first two predator species did not prey on TRM, whereas A. cucumeris fed on each of the life stages of the eriophyid mite. Further experiments showed that A. cucumeris was able to develop and reproduce when feeding on TRM. Implication of these results for controlling TRM in greenhouses is discussed with respect to predator specificity and prey suitability.
