Parasitoids associated with Monochamus galloprovincialis (Oliv.) (Coleoptera: Cerambycidae) within the pine wilt nematode-affected zone in Portugal
Journal of Pest Science 78 (2), 57-62
Abstract: Until recently, the pine sawyer Monochamus galloprovincialis (Olivier) (Coleoptera; Cerambycidae) was considered a secondary forest pest in Portugal. Its pest status changed when it was found to be the main vector of the recently introduced pine wood nematode (PWN) Bursaphelenchus xylophilus (Steiner and Bührer) Nickle (Nematoda; Aphelenchoididae). A survey in three locations within the PWN-affected zone was conducted in order to identify parasitoids associated with immature stages of the beetle and to evaluate their importance. No parasitoid was found associated with the insect eggs whereas 10% of the larvae were found parasitised by three Braconidae. Cyanopterus flavator Fabricius was the most numerous species; Iphiaulax impostor (Scopoli) and Coeloides sordidator Ratzeburg were the other species present. A review of the parasitoids associated with Monochamus in Europe, eastern Asia and North America was made, and the possibility of using the local species in future biological control programmes in Portugal is briefly discussed.
