Tricho-Fruits® is a biological control product used to protect trees and shrubs in gardens, urban parks, residential courtyard and small orchards. Inside the card, there are trichogramma pupae in host eggs, a tiny moth egg parasite wasp of the species Trichogramma minutum.
Trichogramma wasp is tiny and less than 1 mm. After mating, the female is actively searching for moth and butterfly eggs such as Codling moth (Cydia pomonella), obliquebanded leafroller (Choristoneura roseceana), Leafroller (Platynota sp.) and several other defoliating species. She lays her eggs inside these. As the larva develops, it consumes the contents. A new generation emerges after 2 weeks.
The species Trichogramma minutum has been specifically selected for maximum results in suppressing moth and butterfly (Lepidoptera) eggs in fruit trees. Usually, the introduction of the Tricho-Fruits® begins with flowering. The optimum conditions of use are when the ambient temperature is above 15 ° C. Generally, 5 releases per season are usually required for good pest control. Apply new card on the tree to be protected every 7 days.
