Trichogram strains against boxwood moth

Trichogram strains against boxwood moth

Relax, there is today an effective biological solution, the trichogrammes. These are tiny wasps that destroy the eggs of the mites.

The use of trichograms against the moth of textile or ringworm ( Tineola bisselliella ) in Canada is relatively new and often raises many questions! In this article, we present this biological control method and answer the most frequently asked questions.

The textile moth, also called ringworm of the garment, is a small butterfly of the species Tineola bisselliella . The larva of this species can only complete its life cycle by feeding on animal fibers such as wool, hair and feathers.

The female prefers to lay eggs in dark and quiet corners, close to animal materials (eg wardrobe, storage room, chest, attic, etc.). The whitish eggs measure 0.5 mm and are very difficult to observe in the tissues. At birth, the small larva is about 1 mm.

When temperatures are 25 to 30 Celsius, the larva completes its cycle in 2 months. At the end of its larval stage, it measures nearly 10mm. With the animal material she feeds on, she will make a small cocoon in the shape of a tube.

The adult emerges after 1 to 2 weeks. He has atrophied mouthparts and is therefore unable to feed himself. At room temperature, the butterfly can live up to 14 days. Once mated, the female will be able to lay up to 250 eggs during her lifetime.

The presence of rodents may favor the proliferation of ringworm of clothing. The use of poison to reduce populations may cause another additional problem: a mouse killed with a poisoned bait may break down in an inaccessible location (walls, ceilings, etc.) and become a ringworm reproduction of clothing. The larvae of these will feed on the hairs, one of the last vestiges of the mouse.

It is possible to apply diatomaceous earth, a powder made up of multiple small fossilized skeletons of algae that pierces and kills larvae, in cracks near walls, skirting boards and other openings in walls. This will prevent and intercept the migration of live larvae to your home.if you need more info just visit this site diagnostic capillaire

Trichogramma are widely used in Europe where they are one of the main solutions against food and textile mites. Moreover, the Natural History Museum in London, struggling with infestations of moths in their collections, recently chose the trichogrammes to overcome.
