Feltiella acarisuga is a tiny gall-midge that feeds on two-spotted spider mites and various other species of spider mites. We recommend Feltiella be used with P. persimilis when spider mite infestations are severe to rapidly knock back the pest mites. Commonly used on tomatoes, cucumbers, sweet peppers, other greenhouse crops and field strawberry crops, Feltiella works best on plants that have hairy stems. Of particular interest to greenhouse growers is that they have been shown to work quite effectively in situations where other mite predators have been ineffective by themselves.

Optimal Conditions: 68° - 81°F, ≈80% RH

Appearance & Life Cycle: The entire life cycle is about 15 days. Adults are about 2 mm long, pinkish-brown, and have long legs. They do not prey on spider mites, but drink water and nectar. The female adult gall-midges actively search for spider mite colonies and deposit eggs next to them for about 5 days. Eggs laid are 0.1 x 0.25 mm in size and are shiny and translucent. They hatch in 2 days. The larvae that hatch from the eggs are 0.2- 2 mm in length and are orange-brown. They feed on all stages of the spider mite for 4-6 days, depending on the temperature, humidity, and abundance of spider mites. Larvae pupate inside a white cocoon, usually on the underside of leaves along the veins. It takes 4-6 days to produce an adult.

Release Rates: Some crops, including tomatoes & other highly resinous crops, require higher release rates.
