Parasitism by Coptera haywardi and Diachasmimorpha longicaudata on Anastrepha flies with different fruits under laboratory and field cage conditions
BioControl 59 (3), 287-295
Abstract: Larvae of Anastrepha ludens and A. serpentina that developed in mango and sapodilla fruits, respectively, were exposed to Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae) and sequentially exposed as pupae to Coptera haywardi (Oglobin) (Hymenoptera: Diapriidae). Sequential exposure to both parasitoid species contributed to a decrease in fruit fly emergence due to higher levels of parasitism, which varied according to fruit type. In creole mango, D. longicaudata represented the highest percentage of parasitism. C. haywardi parasitism was greater in pupae from Ataulfo mangos and sapodilla, where the pulp size and volume may have acted as a refuge, allowing fly larvae to escape and leaving a greater number of unparasitised pupae available to C. haywardi. Similar results were obtained under field cage conditions, but the level of parasitism by C. haywardi was lower, suggesting that its effectiveness has some limitations under natural conditions. Our results suggest that both species can exert complementary parasitism, which represents an alternative worth to investigate under open field conditions.
