We produce tryhohrammas (T. evanescence Westwood), parasitizing eggs of Lepidoptera insects. Type deemed identical Trichogramma maidis Pintureau and Voegele, and T. brassicae. Trichogramma is the most widely used in the world of biological control agents and used in the fight against about 200 species of butterflies.

Wasps are delivered as pupae parasite eggs in contaminated media Sitotroga cerealella, in packs of five million individuals and 100,000 individuals. At the request of customers to allow to change the packaging of the product comfortable volumes.

Our product according to GOST 5016: 2008 quality meets Class I and includes the following indicators:

Seven important points of Trichogramma

How does the trichogramma work?

Females seek appropriate Trichogramma eggs of insects and butterflies lay their eggs in them. As a result, the egg’s parasite Trichogramma larva revived and eats the eggs of media content. Further, the larva to pupa inside exchange an empty shell egg carrier. In small carriers eggs larva develops one rider, but there may be several larger eggs.

Eggs out of the infected adults Trichogramma, not larvae media. Thus, damage to crops is reduced, but rarely completely eliminated. Different sources indicate different levels of parasitism, from 40% to 80%. In some cases indicated a higher percentage, but in the field of this parasitism may occur due to natural populations parasit’s eating eggs.

What does the trichogramma do?

Eviction Trichogramma (Trichogramma) will reduce the total damage caused by lepidopteran insect pests. The exact extent of the reduction will depend on many different factors, including the type of target pest of initial population and others.

Entomophagy is used on a wide range of agricultural (cereal, technical, vegetable) and decorative flower crops in the open field and greenhouse.

When and where do we use the product?

Use Trichogramma on any cultures where lepidopteran insect pests have caused significant damage to leaves, fruits, flowers or stems. You must remember that pests with biological differences in reproduction (various dates, places and methods clutches of eggs).

Correct timing is essential for success. Lines of Trichogramma not attack the larvae, pupae and adult butterflies, although usually the presence of adult pests means that there lay their eggs. It should use monitoring devices to identify times when adults are active on culture. To monitor butterflies are many traps and pheromone lures intended for this purpose. An alternative species active at night, is the use of conventional traps.

In cases when the particular culture can develop several generations of pests, conduct evictions as early as possible early in the season when pests’ population is low. Eviction parasites at this time will provide a significant reduction in the total populations of the target pests.

When the trichogramma should not be used?

Do not use Trichogramma, when the level of damage Lepidoptery is high: immediate reduction of damage will not be provided because trichogramma fall upon larvae. There may be some reduction in the next generations of the pest, but for a relatively small reduction will require a very large number entomophagy. You should not use the product in cases where there is published information that the target pest is not appropriate carrier for Trichogramma evanescens.

How to apply the trichogramma?

The most effective manual method is considered settling in Trichogramma revival condition. Use small aircraft on a large area.

Standards evictions also vary widely depending on the culture, and is, an estimated 50 000 - 250 000 thousand individuals for 1 ha.

Compatibility with chemicals

Types of Trichogramma sensitives to pyrethroids and other insecticides. Drugs that kill the eggs of lepidopteran insects - carriers will inevitably lead to a decrease in population resulting from the death of the parasites eggs containing larvae of the parasite, but Trichogramma pupae can survive.

Beware of counterfeits

Unfortunately, in recent times the market offer increased product unknown quality and manufacturers. Note the use of dubious terms "laboratory trichogramma", "hardened", "trichogramma double, triple distillation" and so on.

The only indicator of product quality is GOST compliance №5016: 2008. With the intent to buy Trichogramma, Choose and provide samples for research in specialized laboratories.
