Effect of Diachasmimorpha longicaudata releases on the native parasitoid guild attacking Anastrepha spp. larvae in disturbed zones of Chiapas, Mexico
BioControl 62 (5), 581-593
Abstract: We evaluated the effect of augmentative releases of Diachasmimorpha longicaudata (Ashmead), on the native parasitoid guild of Anastrepha spp. over a two year period in zones adjacent to mango commercial orchards in Chiapas, Mexico. We chose two 15 ha working zones, 15 km apart, harbouring fruit fly hosts of varying densities without chemical control. In 2013, parasitoids were released in zone "A" while zone "B" served as control. In 2014 zones were exchanged. As expected, releases of D. longicaudata significantly increased total parasitism, from around 0.5–5% to over 22%, but annual parasitism by native parasitoids was only significantly affected in zone "A". The numbers of native parasitoids were higher in zone "A" in both years, and diversity (H') was not affected by D. longicaudata releases in both zones. Our results suggest that releases of D. longicaudata affect the relative abundance but not the species richness of native parasitoids.
