Resumen en inglés

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.

Resumen en inglés

Female black pupae from the Anastrepha ludens genetic sexing strain Tapachula-7 were eval- uated as hosts for Coptera haywardi. We studied the host acceptance and the effects of age, irradiation and automated mechanical separation of black pupae on the emergence, survival, fecundity and flight ability of parasitoid C. haywardi adults. Our results indicated that black pupae are viable hosts for C. haywardi. Adult emergence was greater when the exposed pupae were three and five days old. The impact that occurred during mechanical separation reduced emergence by 16 %. The tested irradiation doses (25, 35 and 45 Gy) did not significantly affect adult emergence. No significant differences in longevity, fecundity or flight ability were observed between parasitoids that emerged from the Tapachula-7 black pupae and those that emerged from the standard mass-reared strain.

Resumen en inglés

We studied the oviposition performance of Fopius arisanus (Sonan) (Hymenoptera: Braconidae) attacking eggs of four fruit flies of the genus Anastrepha Schiner (Diptera: Tephritidae) under laboratory conditions. The complete process of oviposition on an individual egg of Anastrepha ludens (Loew) lasts in average 85.4 ± 2.9 s, including a tremor (25.8 ± 1.03 s) observed in the middle of this process related to the egg’s descent. The average parasitism of A. ludens egg was 60.9 ± 7.5%, with only 1.2% of superparasitized eggs. During individual acts of oviposition, we noted that F. arisanus possesses a highly flexible ovipositor that curves easily as it searches for additional suitable eggs, which may be of particular benefit when a female finds large clutches of eggs. The individual oviposition of F. arisanus in host fruits attacked by Anastrepha spp. varies with the egg clutch size of each fruit fly species: A. serpentina laid the biggest egg clutches (21.3 ± 1.4), followed by A. ludens (14.2 ± 0.9), and A. striata (1.0 ± 0.0) (=A. obliqua). The time spent by F. arisanus in individual ovipositions was parallel to these findings, reinforcing the idea that F. arisanus attacks several eggs in each individual insertion of its ovipositor. Neither formal oviposition acts, nor adult emergences of F. arisanus were registered in A. obliqua. We discuss the potential of F. arisanus as natural enemy of fruit flies of the genus Anastrepha, and explore the eventual developing of its mass rearing.
