Tricho PRO5 Trichogramma evanescence
Cardboard tube 0.5 l (100 g);
Cardboard tube 1 l (250 g).
Attention! A special container and a refrigerant are used to transport trichogoramma, which maintains the temperature to create optimal storage conditions for the product.
It controls a wide range of Lepidoptera pests, including very effective against the armyworm complex, including Agrotis segetum, Helicoverpa armigera, and Pieris brassicae. In orchards, brown trichogramma is used as an entomophage to control Cydia pomonella, as well as leafworms. Trichogramma evanescens is extremely effective in controlling the corn borer (Ostrinia nubilalis).
A wide range of vegetables, grain and fruit and berry crops in protected and open ground.
Application is carried out at dusk (at sunset or early in the morning), both in protected (greenhouses, hotbeds) and in open ground. Application must be carried out evenly over the entire protected area. To ensure quality control for each generation of the pest, it is necessary to carry out from 2 to 4 releases of the entomophage, adhering to the interval between them of 5-7 days. And if a trichogram of different ages is used, then 2-3 releases are needed with an interval of 10-12 days.
The release rate of Trichogramma ranges from 40-200 thousand individuals per hectare. Usually, the introduction of an entomophage occurs based on the following standards:
Vegetable crops: 80-100 thousand individuals per 1 ha;
Corn: 200-400 thousand per 1 ha;
Fruit: 80 thousand individuals per 10 trees.
These figures are general, to understand the required eviction rate for your specific crop and pest, contact the technologists of the ECOCULTURE company.

Trichogramma evanescens – brown trichogramma, also known as "cow". This is a small (0.3-0.5 mm long) parasitic wasp that infects the eggs of many pests in protected and open ground. Females lay eggs in Lepidoptera eggs, while injecting a specific substance that blocks the development of the Lepidoptera embryo. All development of the wasp takes place inside the host egg, the contents of which feed on the larva. Thus, the wasp destroys the pest already at the egg stage.
Adult Trichogrammas feed on nectar. One female destroys up to 300 eggs of pests during her life, while the number of females in the population can reach 90%. At an optimum temperature of 25-30°C, one generation of the entomophage develops in 10-13 days. Imago wasps live 7-14 days. A significant advantage of the use of Trichogramma is the low species specificity of the wasp and the high results of pest control with preventive use. Due to the peculiarities of its life cycle, Trichogramma is effectively used in the control of many types of crop pests.
Trichogramma finds its victims by capturing a specific chemical - benzyl cyanide, which plays the role of "antiaphrodisiac" in some butterflies. This compound comes from the fertilized female and reduces her attractiveness to males. After mating, the male marks the female with benzyl cyanide and this increases the chances of his offspring to survive, since the probability of fertilization of this female by "competitors" is reduced. Trichogramma females are able to trap this substance, follow the scent of the female and lay their eggs in the fresh eggs of the pest.
