FLEP Can Help Forest Owners Address Sirex Woodwasp Concerns

摘要

Sirex noctilio, a European Woodwasp, is an invasive insect that has been discovered this year in at least 18 central and western New York counties. Sirex Woodwasp infests various species of pines which generally results in tree mortality. Unhealthy, stressed trees growing in overcrowded conditions are much more prone to infestation, damage and mortality. The female Woodwasp chooses unhealthy pines, injecting a toxic mucous and symbiotic fungus, when laying their eggs. The fungus and toxins working together can kill trees in a short period of time, creating a suitable environment for larval development.
