Sirex woodwasp: biology, ecology and management

Abstract

Sirex woodwasp (Sirex noctilio F.) is an aggressive nonnative woodwasp that kills pine trees. In the southern hemisphere, it has caused up to 80 percent mortality in unthinned, overstocked pine plantations. In its native range of Europe, northern Asia, and the northern tip of Africa, sirex attacks mainly pines (e.g., Pinus sylvestris, P. nigra, P. pinaster), but it is rarely a pest (Spradbery and Kirk 1978). In the Southern Hemisphere, it has attacked many of the pines that are native to North America (e.g., P. radiata, P. taeda, P. elliottii, P. banksiana, P. ponderosa, P. contorta).
