Resumo: The eucalyptus gall wasp (Leptocybe invasa) causes severe damage to its host plants. One of the main strategies to control its dispersion is biological control with parasitoid hymenopterans. Some parasitoid species, like Megastigmus brasiliensis, may have potential in the biological control of gall wasp in the southern region of Brazil. The study aimed to report the occurrence of parasitoids associated with L. invasa as well as to gather information about its distribution in the central region of Rio Grande do Sul state. The collections were carried out in twelve cities in the central region of the state between December and March 2015-2016 and 2016-2017. Eucalyptus branches with galls were collected and kept in laboratory under controlled temperature conditions (28 ± 2°C). After two months, the collected individuals were screened and identified. In all sampled cities there was the presence of gall wasp with different levels of density, which may be related to the genetic material of host plants and the local weather conditions. The only parasitoid collected was M. brasiliensis. This work presents the first occurrence record of M. brasiliensis in Rio Grande do Sul and the second record in Brazil.

Uma das principais estratégias para controlar sua dispersão é o controle biológico com himenópteros parasitoides. Existem espécies, como o parasitoide Megastigmus brasiliensis que apresentam potencial no controle biológico da vespa-da-galha na região Sul do Brasil. O trabalho teve como objetivo registrar a ocorrência de parasitoides associados à L. invasa bem como levantar informações a respeito de sua distribuição na região central do Estado do Rio Grande do Sul. As coletas foram realizadas em doze municípios na região central do Estado entre os meses de dezembro e março de 2015-2016 e 2016-2017. Ramos de eucalipto com galhas foram coletados e mantidos no laboratório em condições controladas de temperatura (28 ± 2°C). Após dois meses, foi feita a triagem e identificação dos indivíduos coletados. Em todos os municípios amostrados houve presença da vespa-da-galha com diferentes níveis de densidade, o que pode estar relacionado ao material genético da planta hospedeira e às condições meteorológicas locais. O único parasitoide coletado foi M. brasiliensis. Este trabalho apresenta o primeiro registro da ocorrência de M. brasiliensis no Rio Grande do Sul e o segundo registro no Brasil.Departamento de Diagnóstico e Pesquisa Agropecuária.
