Sirex woodwasp is a pest of the following plants: evergreen woods, most commonly pine, but also including spruce, firs, and larches.
Evidence of sirex woodwasp damage includes: decay and death of wood, evident by chlorosis of the crown of the tree which turns needles a reddish-brown, followed by wilting foliage and needle fall. External evidence of less progressed infestations include round emersion holes and resin flows on the bark. Internal evidence include larval galls along the wood grain containing compacted frass.
CBP Agriculture Specialists, please refer to manuals for general inspection guidelines. When performing inspections, check wood articles for larvae and pest feeding evidence, including round holes and tunnels. If possible, photograph the damage as well as the ISPM 15 (IPPC) wood marking if marked. The trunk, stem, and bark of wood products can be affected, therefore both wood and wood packing materials should be inspected thoroughly.
The sirex woodwasp has a sturdy, cylindrical body without a waist, but with a pointed abdomen.
The female body is 15–36 mm (0.59–1.42 in), and the male is 9–32 mm (0.35–1.26 in) long. Both sexes have long, black, bristle-shaped antennae, which are rather close together.
The body of the male is black, except for the orange middle part of the abdomen. The wings are yellowish-translucent and the antennae are black. The front pair of legs have a yellowish-orange colour, the back pair is heavily thickened and is coloured black on the posterior splint and tarsus, while the femur is orange.
The females are iron blue, and have orange legs and black antennae.
