Phytoseiulus persimilis – Predatory mite
Mite-E ™ is known to be useful in both greenhouse and outdoor crops, such as rose, orchid, bean, capsicum and strawberry as part of an integrated pest management programme.
Not 100% compatible with Mite-A™, which is a more generalist predator, be careful not to apply high concentrations of Mite-A™ with Mite-E™ applications.
Delivery *Important Information*
For best results, release Mite-E when spider mite populations are still low. Monitoring is essential.
If spider mites are present in "hot spots" or in larger numbers, treatments of 20-50 mites per m2 may be necessary to bring the pest levels down more quickly.
Mite-E™ is a small highly active predatory mite, orange to bright red in appearance. Adult females are 0.5-0.6 mm long.
Adult female Mite-E™ lays her eggs amongst colonies of two-spotted spider mites.
Both nymph and adult predatory mites actively search for their prey and will feed voraciously on all stages of spider mite from eggs through to adults.
Under optimal conditions (20°C and 65% RH) Mite-E™ has the potential to devour up to five adult spider mites and twenty eggs and larvae per day, thus reducing two spotted spider mite populations over several weeks.
Mite-E™ is almost entirely dependent on two spotted spider mite as a source of food; once all prey has been consumed they will go out in search of a new food supply. If no food is found, the mites may become cannibalistic.
Under optimal conditions , Mite-E™ has a substantially faster life cycle than two spotted spider mite. The sex ratio of adult Mite-E™is four females to each male, and females are capable of laying up to 60 eggs in their life time. These factors contribute to the success of Mite-E™ as a predator.
Mite-E™ is not considered harmful to humans and animals, and no environmental impacts are expected.
Favoured conditions for Mite-E™ are temperatures above 20 °C for a time during the day and a relative humidity of 65%.
Mite-E™ will consume two spotted spider mites and reproduce at temperatures and humidity that are not ideal, but at a slower rate.
Mite-E™ is supplied in units of 500 or 1000 adult mites in Vermiculite.
Each unit has a small quantity of two spotted spider mites as a food source during transit.
Mite-E™ is dispatched via courier and should reach you within 1 to 2 days.
After 2-4 weeks, following the release of Mite-E™, you should be able to see signs of the predator working.
Two spotted spider mites that have been eaten change from pale green to brown and appear shrivelled. Use a 10x hand lens to check, as live and dead mites can appear similar to the naked eye.
Before introducing Mite-E™ into your crop please check residual chemical affects and ensure you know chemical compatibilities of products that may be applied.
