چکیده
A new host record is reported for the braconid wasp Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), parasitizing papaya fruit fly larvae Toxotrypana curvicauda Gerstaecker (Diptera: Tephritidae) in México.

Superparasitism in the Fruit Fly Parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae) and the Implications for Mass Rearing and Augmentative Release
Superparasitism, a strategy in which a female lays eggs in/on a previously parasitized host, was attributed in the past to the inability of females to discriminate between parasitized and non-parasitized hosts. However, superparasitism is now accepted as an adaptive strategy under specific conditions. In fruit fly parasitoids, superparasitism has mainly been studied as concerns the new associat...

The preferences of Diachasmimorpha longicaudata (Ashmead) for larvae of Anastrepha fraterculus (Wiedemann) and Ceratitis capitata (Wiedemann) were evaluated under laboratory conditions in no-choice and dual-choice tests, based on percent parasitism, proportion of emerged parasitoids, proportion of female offspring, and number of parasitoid female visits to and ovipositor probes on the artificia...
متن کاملImmature Stages of Development in the Parasitoid Wasp, Diachasmimorpha longicaudata
The morphological changes experienced during the immature stages of the solitary parasitoid Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae: Opiinae) were studied. This natural enemy of several species of tephritid fruit flies is widely used in biological control strategies. Immature stages are poorly understood in endoparasitoids because they exist within the host. In the prese...
متن کاملIrradiation of Anastrepha fraterculus (Diptera: Tephritidae) Eggs to Inhibit Fly Emergence in the Mass-Rearing of Diachasmimorpha longicaudata (Hymenoptera: Braconidae)
As the incidence of Anastrepha fraterculus (Wiedemann) has increased in Southern Brazil in the past 3 yr, an initiative to release sterile flies and parasitoids has started. In order to make feasible the mass-rearing of the parasitoid Diachasmimorpha longicaudata (Ashmed), this study investigated the suitability of A. fraterculus larvae derived from irradiated eggs as host for D. longicaudata T...
متن کاملA compound produced by fruigivorous Tephritidae (Diptera) larvae promotes oviposition behavior by the biological control agent Diachasmimorpha longicaudata (Hymenoptera: Braconidae).
Tephritid fruit fly parasitoids use fruit-derived chemical cues and the vibrations that result from larval movements to locate hosts sequestered inside fruit. However, compounds produced by the larvae themselves have not been previously described nor their significance to parasitoid foraging determined. We collected the volatiles from four species of tropical and subtropical Tephritidae: Anast...
