Trichogramma can be applied to all types of plants and crops. However, it’s crucial to understand that Trichogramma (tiny wasps measuring up to 0.3 mm) works against the eggs of pests. Identifying the pest species is essential to determine the appropriate Trichogramma type or a mix of types, along with the correct proportions. Therefore, knowing the specific pest you are targeting is critical for effective application.

Once you receive a Trichogramma container for manual colonization, it is recommended to apply it immediately, as it contains eggs of a living organism.

If immediate use is not possible, it can be stored for up to 48 hours in a regular household refrigerator at a temperature of 4-8°C. Trichogramma is safe for all other products in the fridge and poses no risk to human health.

It can last longer under these conditions, but its effectiveness may decrease.

No, the container is not to be opened! It contains trichogramma eggs, which must be protected from touching, as from intrusion by other insects or organisms. After the trichogramma hatches from the egg, it exits through openings in the cardboard box and begins to search for pest eggs.

It depends on the pests. Usually, treatments are done several times, every 10 to 20 days. Each manual colonization package contains detailed instructions based on the specific pest being targeted.

No, trichogramma is completely harmless and is not dangerous to human or pet health. It is a microscopic wasp, up to 0.3 mm in size, that feeds only on pest eggs. If there is no food, it cannot survive. Therefore, after performing its natural functions, it dies. 

Trichogramma cannot bite, sting, injure, or cause any harm, as it is microscopic and has no interest in humans or animals.

No! Trichogramma is a microscopic wasp and physically cannot, nor is it in its nature, to confront bees. On the contrary, trials are currently being conducted to prove that trichogramma can help control mites in bees. 

 

When agricultural areas around bee colonies are treated with natural bioagents like trichogramma, biodiversity and the natural balance of soils and plants in the region are preserved.

Unlike the use of chemicals that destroy both harmful and beneficial insects, Trichogramma only feeds on the eggs of certain pests, such as moths, butterflies, and noctuids. This targeted approach helps preserve beneficial insects and biodiversity.

We understand that by using Trichogramma in more agricultural fields, we contribute to the preservation of biodiversity, including protecting the lives of some of the most beneficial insects to humanity – bees.

The colonization with Trichogramma begins immediately after the pest flight is detected. It works on the eggs of the pests. Once the flight starts and is confirmed, the reproduction of the pests begins. This is the moment when Trichogramma can find food (the eggs of the pests) and start working.

Yes, watering is possible when using Trichogramma. Despite its tiny size, it can find shelter during watering, rain, or adverse weather conditions. Once the conditions become optimal for its survival, it will activate and begin its work.

Trichogramma can be applied no less than 5 days AFTER treatment with a plant protection product. It should never be used together with chemical treatments, as they destroy both pests and beneficial insects.

Trichogramma is active within a temperature range of 17 to 26°C. Outside of this range, it hides and waits for favorable conditions to become active again.

Depending on whether it is outdoors or in a greenhouse, as well as the method of colonization, our recommendations are:

  • When using manual colonization containers outdoors, in a field or garden, between 20 boxes per hectare are placed, depending on plant density and height.
  • In greenhouses, depending on plant height, 20 boxes per decare are placed.
  • For manual colonization with capsules, the norm is 20 capsules per decare.
  • For drone colonization with capsules, the norm is 10 capsules per decare.

Yes, there is a recommended scheme, but it is important to note that each specific location has its unique characteristics that the farmer must consider.

When using containers for manual colonization, maintain a distance of 2 to 6 meters (depending on plant height and planting density). If plants are in rows, place the containers in a staggered arrangement on adjacent rows. The Boxes (containers) have a hanger. Containers should be hung no lower than 10 cm from the ground, typically at the first branching. 

Trichogramma exists in nature, but its population density in the wild is insufficient to naturally have a positive impact on pest control. That is why we cultivate these beneficial insects in a laboratory environment on a large scale.

Trichogramma, like all living creatures, has its own life cycle: egg, larva, pupa, adult trichogramma, and so on.

For survival and reproduction, Trichogramma needs food. It feeds exclusively on the eggs of harmful insects—moths, butterflies, night moths, and over 400 species of economically significant pests. Without food, it cannot exist, and its life cycle ends. If it lacks the necessary conditions for feeding, reproduction, and development, its life cycle lasts only 3 to 4 days.

It is never too late to treat with trichogramma!

Different pests from the Lepidoptera order have different flight and egg-laying periods, with multiple generations. Even if you miss the monitoring and initial flight detection, treatment with trichogramma always guarantees much better plant protection and suppresses pest populations.

However, the more accurately you determine the start of the pest flight, the better you will protect your crops, and the harvest will be of better quality and in larger quantities.

Due to its microscopic size (0.3-0.7 mm), trichogramma cannot fly more than 10 meters. However, it is a living organism that moves, so it is possible that it will travel and protect the plants of your neighbor. It is important to point out – the more areas treated with trichogramma in a region, the lower the pest pressure for all farmers!

It is scientifically proven that representatives of the Lepidoptera order can travel 50-100 km in one day under favorable atmospheric conditions using air currents.

Here’s an interesting fact: The record is 1,500 km in 36 hours from Mississippi to Canada by Spodoptera frugiperda.

There is no issue with applying fungicides while treating with Trichogramma. Our formulas are specifically designed (and this is truly the case) to ensure a continuous emergence of Trichogramma daily throughout the application period (10 to 12 days, as stated on the packaging for each product). Even if the fungicide affects the newly emerged Trichogramma, new ones will continue to hatch the following day.
