Feltiline contains Feltiella acarisuga, some midges that prey on spider mites. They consume all stages of mites: adults, nymphs and eggs. As soon as they hatch, the larvae will explore the plant to look for mites, whatever their stage. Feltiline larvae are among the most effective predators of spider mites: they are very active and one larva can consume 30 mites or 80 mite eggs per day.
Feltiline adult females will seek out mite breeding grounds to lay their eggs nearby. Their excellent prospecting capacity makes them a very efficient solution for use on mite outbreaks. Adults are not predatory; they only need water and sugar (honeydew) to live. The presence of these foods in sufficient quantities extends their lifespan and their fertility which can reach 100 eggs per female.
Feltiline is preferentially used in situations where there are a lot of prey, and is to be used as part of a program presenting solutions for fundamental control of mites (including the use of predatory mites).
Feltiline can be used in a wide range of conditions: active from 18°C, it can also be used in spring or autumn. It is also active in dark conditions, at dusk and at sunrise. It will be preferable to use Feltiline in conditions of sufficient humidity (80%).
They need more than 12 hours of light and real dusk to complete their life cycle.
