“Feltiella acarisuga are tiny midges that feed on two spotted spider mites. These predatory midges are effective destroyers of spider mites and a very promising biological control for tomatoes, cucumbers, sweet peppers, other greenhouse crops and field strawberry crops where spider mite infestations are a problem. Feltiella work best on crops which have hairy stems. Of particular interest to greenhouse growers they have been shown to work quite effectively on tomatoes on which P. persimilis have been ineffective. Feltiella is sold in release units of 250 which can be hung in the crop and opened for quick release. Shipping Included in Price Orders placed by Tuesday are shipped the following Monday or Tuesday.”

“An excellent general predator for control of spider mites on roses and vegetable crops in greenhouses. This predator can also help suppress cyclamen mite in strawberry fields and broad mite in greenhouses. It tolerates higher temperatures and lower humidities than P. persimilis. Preferred food: Two-spotted spider mites and many others. Predators will consume egg, nymph and adult stages of pest mites. Neoseiulus californicus is an oblong, tiny predatory mite that feeds on a variety of prey. Use on crops including: cucumbers, tomatoes, strawberries, tropical foliage plants, and greenhouse roses. Use in gardens, fields, orchards and greenhouses. Shipment, biology and release: Use these beneficial mites when temperatures are between 60-80 degrees F. and there is a minimum of 60% humidity. These predatory mites consume their prey at a more leisurely pace (one adult or a few eggs per day), and can survive longer under starvation conditions. Release rates: Use 50 adults per 9 sq. ft. of”

“Use these predators in addition to spider mite predators (predatory mites) when spider mite populations are especially high. Spider-mite destroyers are very efficient locators of spider mite colonies in greenhouse and field crops. Actually tiny ladybugs, spider-mite destroyers earn their keep by eating more than 40 mites per day as adults. Use these predators in addition to spider-mite predators (predatory mites) when spider-mite populations are especially high. Spider-mite destroyers eat all stages of spider-mites, and find new infestation sites on their own by flying. Life cycle Egg to adult takes about 18 days at 70°F with a total lifespan of perhaps 9 weeks. As adults, female spider-mite destroyers lay up to 15 eggs per day.100 spider-mite destroyers is enough to get a colony of them started in an average home greenhouse, as they’ll breed from there. Spider-mite destroyers are too new to have established preferred temperature ranges, but they’re known to survive temperature”
