Abstract(s)
A vespa-das-galhas-do-castanheiro, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) é originária da
China e, em Portugal, foi referenciada pela primeira vez em 2014, na região de Entre-Douro-e-Minho. Rapidamente se
estendeu às regiões da Beira Interior e Litoral e, posteriormente, a Trás-os-Montes. O meio de luta mais eficaz contra
esta praga é o tratamento biológico com o parasitoide Torymus sinensis Kamijo (Hymenoptera: Torymidae), apesar do
parasitismo natural em algumas regiões também poder ser importante. O conhecimento da diversidade de parasitoides
autóctones e do seu papel na limitação natural das populações da vespa-das-galhas-do-castanheiro é essencial para
potencializar o combate da praga. Assim, o objetivo deste trabalho foi identificar as espécies de parasitoides associadas
a D. kuriphilus, nas regiões do Minho e Trancoso e avaliar a sua taxa de parasitismo natural.
The chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae) is native to China and, in Portugal, it was detected for the first time in 2014 in the Entre-Douro-e-Minho region. It invaded very rapidly Beira Interior and Litoral and, lately, Trás-os-Montes regions. Currently, the most effective management tactic used to control this pest is the release of the parasitoid Torymus sinensis Kamijo (Hymenoptera: Torymidae). Knowledge on the diversity of native parasitoids, as well as on their impact as biological control agents of chestnut gall wasp is essential to potentiate the control of this pest. Therefore, the aim of this work was to identify the species of native parasitoids associated with D. kuriphilus and to evaluate their rate of parasitism.
