Ecology of the woodwasp Sirex noctilio : tackling the challenge of successful pest management
The invasive woodwasp Sirex noctilio has become one of the most significant pests of pine forests throughout the northern and southern hemispheres. In Patagonia (southern Argentina), S. noctilio was first detected in the early 1990s. However, in less than two decades, and despite intensive control efforts, populations have spread, and outbreaks have been observed. In this paper, we outline and define several key ecological and behavioral features of S. noctilio (namely, spatiotemporal population dynamics, phenology and dispersal) and briefly discuss their implications for the design, implementation and evaluation of local and regional management strategies. We argue that limited information on pest ecology and the extrapolation of control measures without local adaptation may together have affected management success. We conclude that efforts directed to understanding of pest ecology and life-history traits as expressed in specific invaded habitats may help us improve our competence in controlling invasive forest insects.
