Trichogrammes against the box borer
The trichogramma (Trichogramma sp.) Is a small insect measuring nearly 1 mm. This small parasitoid wasp specializes in the parasitism of butterfly eggs.
After mating, the female actively searches for eggs of moths to lay her eggs inside them. It is able to detect the smell of eggs or even the smell of ringworm scales of clothes.
Once the parasitic ringworm is hatched, the trichogramma larva grows there and feeds on the future developing larva. A new adult (trichogram) will emerge from the egg after 2 weeks. When there are no more clothes mites, trichogramms disappear naturally from the environment.
A textile moth infestation can be a difficult problem to solve. In the city, the source of the problem may be outside the dwelling, in an apartment on the outskirts, in the walls of the building (strongly linked to the presence of rodents), in the cornices where birds’ nests are found, etc. .
To be able to resolve the situation, trichogram cards must be applied to the source of the problem. When there is a constant intake of new adults, due to a problem of isolation or infestation on the periphery, the trichogrammes can not settle the situation definitively.
For several years, Anatis Bioprotection has been distributing trichogramma kits to eradicate ringworm populations in apartments, homes, pet stores, stores and warehouses across Canada.
This alien-like lifestyle is found in other insects, too. There are flies, moths, and beetles that are parasitoids, making their living by exploiting other insects. Parasitoid insects are useful to humans — we release them to sting the caterpillars and other pests that attack our beloved crops. This complicated system of insects inside insects, like Russian nesting dolls, is further complicated by the bacteria that live inside the “insects that live inside insects” (say that three times fast). As I mentioned previously, my favorite partner to Trichogramma is the bacterium Wolbachia.
Wolbachia is particularly intriguing because it lives inside of 40-60% of all insect species, as well as other arthropods (like spiders and scorpions) and even some nematodes (small worm-like animals). Insects alone represent more than half of earth’s biodiversity. if you need more info just visit this site trichogramme.
