Sirex Noctilio

O nematóide Deladenus (Beddingia) siricidicola (Nematoda: Neotylenchidae) é o principal agente de controle de Sirex noctilio (Hymenoptera: Siricidae), vespa-da-madeira. ao esterilizar as fêmeas do inseto, atinge níveis de parasitismo próximos a 100%, com média de 70%. o monitoramento da eficiência do nematóide tem sido realizado pela avaliação da sua presença no aparelho reprodutor de machos e fêmeas do inseto. porém, esse processo é exaustivo e antieconômico quando aplicado a amostras muito grandes. o objetivo desta pesquisa foi testar a técnica da amostragem seqüencial para avaliação da eficiência do parasitismo de Deladenus (Beddingia) siricidicola em adultos de Sirex noctilio, a qual se mostrou como uma alternativa viável, pois se baseia em um tamanho variável de amostra, definido em função dos resultados obtidos durante os levantamentos amostrais, resultando em redução do tamanho da amostra, dos custos da atividade e precisão nos resultados. foram também abordados aspectos do parasitismo por Deladenus (Beddingia) siricidicola.

Abstract The woodwasp, Sirex noctilio Fabricius, is an exotic pest of Pinus L. in the southern hemisphere and North America, and it is an emerging threat in northeastern China. Adult woodwasps have numerous insect competitors for oviposition substrates, and developing larvae must compete for resources with other subcortical invaders. Its mutualistic fungus Amylostereum areolatum (Fr.) Boidon, is less competitive than many other fungal colonists present in pine ecosystems. This study investigated the effects of incidental, host-colonizing fungi on the growth and development of woodwasp larvae and A. areolatum. Fungi were isolated from dead S. noctilio larvae within galleries (primarily Trichoderma Pers, Ophiostoma Sydow, and Sphaeropsis Sacc.), and effects of these fungi on woodwasp brood survival were investigated via inoculations of S. noctilio-infested logs. Larval mortality was significantly increased in sample logs inoculated with Ophiostoma minus (Hedgc.) Sydow Phlebiopsis gigantea (Fr.) Jülich, Trichoderma atroviride Bissett, Trichoderma viride Pers, and Trichoderma harzianum Rifai. Inoculation of logs with O. minus resulted in the highest mortality and greatest reductions in wood moisture content. When grown on artificial media, these fungi grew faster than and inhibited growth of A. areolatum mycelium. We propose that the adverse effects of incidental fungi on the survival of S. noctilio larvae may be caused at least in part by an indirect mechanism involving inhibition of the fungal symbiont. The findings provide potentially valuable information for suppressing S. noctilio populations using microbial control agents.
