Resumo: The nematode Deladenus (Beddingia) siricidicola (Nematoda: Neotylenchidae) is the main control agent of the woodwasp Sirex noctilio (Hymenoptera: Siricidae). It acts by female sterilization and reaches parasitism levels close to 100%, averaging 70%. The monitoring of the efficiency of this nematode parasitism has been done by evaluating the presence of the worm in the reproductive apparatus of male and female wasps, but this process is time consuming and expensive when applied to large samples. The objective of this research was to apply the sequential sampling which has proved to be a viable alternative to evaluate the efficiency of the parasitism of Deladenus (Beddingia) siricidicola on Sirex noctilio. It is based on a variable sample size that is defined in function of the results obtained from the survey, reducing the costs of sampling and obtaining a satisfactory precision level. Some aspects of parasitism by Deladenus (Beddingia) siricidicola are addressed.

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.
