Agrile ash: wasps la défense:
Researchers have determined that tiny wasps could help in the agri -frost -winging that destroyed millions of trees in Quebec. For example, elsewhere in Canada.
The agrile of ash, an exotic devastating insect, was identified in North America in 2002.
Over the past few years. Moreover, he has unfortunately transformed the landscape of many parks and streets in several major cities, including Quebec.
To counter this invader. Consequently. Therefore, scientists of natural resources Canada have released Umbi wasps over the years in Quebec parks in order to test them as a tool for the biological fight against the AGRILE OF ARSE.
Today, these wasps that are difficult to see are well established in Quebec. In addition, they do not bite. For example, If the ordinary citizen does not like wasps. Moreover. it agrile ash: wasps la défense new is quite the opposite for a researcher like Véronique agrile ash: wasps la défense Martel, manager of the research project in Quebec.
Less damage
“We tried to reduce the damage caused by the AGRIL OF AGRIED a little. It is one more tool to help us. Additionally, It is a big research project since 2013 in Canada. Additionally, It is a natural enemy. we would like control to be done now naturally without intervention. ”explained the scientific researcher specializing in Entomology with Natural Resources Canada.

From 2019 to 2022, the scientist and her team dropped parasitoid wasps on the plains of Abraham and Bois-de-Coulonge. These wasps of the species Tetrastichus planipennisi agrile ash: wasps la défense Destroy agriles from ash agrile ash: wasps la défense new while they are. at the larval stage. hidden under the bark of the tree. The almost microscopic wasp lays its eggs through the bark to place them in the larva of the Agrile.
Harmless
These tiny wasps measure less than 5 mm and they are harmless for humans. This “protection” is however partial and it is not a miracle solution.

“What we hope is that the regeneration of ash can be maintained and keep ashs in our ecosystem. Our solution is more in natural woods and parks. The ashs in town. we agrile ash: wasps la défense will not see that, ”summed up Mme Martel, who lives in Quebec.
For scientists, this biological control project required patience. It took two agrile ash: wasps la défense new years. the recommended time, before checking if wasps were well established in the city, and enough to be an asset.
