The Sirex Woodwasp is a large wasp from the Horntail family. Trees that are already suppressed or stressed due to other site or environmental conditions seem to be preferred by the female wasps. 2. Controlling the pine-killing woodwasp, Sirex noctilio, with nematodes. . Sirex noctilio was first detected in Chile in the Valparaíso Region in 2001. It primarily attacks pine trees (sometimes also spruce and fir trees), laying its eggs along with a symbiotic fungus and toxic mucus that kill the tree. The United States Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), is proposing a program to control a nonnative, invasive woodwasp, Sirex noctilio (Hymenoptera: Siricidae). Subsequently, an intense biological control program using the female sterilizing nematode Deladenus siricidicola was implemented in 2010. As the female Sirex woodwasp, Sirex noctilio, prepares to lay her eggs, she secrets a toxic mucus and symbiotic fungus into the tree which work synergistically to weaken, and in some cases kill the attacked tree (s). 68% mortality in other seection.
