Resumen en inglés

In Guatemalan coffee plantations, Ceratitis capitata populations were suppressed by the application of augmentative releases of parasitoids. These releases significantly increased parasitism of this fruit fly over paired no-release control areas. Integrated management plus biological control presented a significant reduction in the pest population. These results support the application of biological control in C. capitata management.

Resumen en inglés

The incidence of superparasitism in field populations of Diachasmimorpha longicaudata (Ashmead), a solitary larval–pupal endoparasitoid, attacking Anastrepha fruit fly species was determined. From 14,550 fruit fly larvae infesting mango fruits in the field, 68.9% (10,038) survived to the pupal stage. Of these pupae, 3780 (37.7%) were parasitized, of which 2075 (54.9%) were superparasitized. The number of oviposition scars per pupa ranged between 1 and 29, although high numbers were rare. The presence of one or two scars per host was frequent, but only 8.6% of pupae had more than three scars. Fruit size was positively related to the level of infestation by Anastrepha spp. and was significantly correlated with the numbers of parasitized and superparasitized pupae by D. longicaudata. The length and width of host pupae were positively related to superparasitism, and superparasitism was positively correlated with a sex ratio biased toward females. Our data show that superparasitism is present in natural populations of D. longicaudata at remarkable rates and confers some advantageous features such as a female-biased sex ratio. These findings favor the election of this species as a viable biocontrol agent for augmentative releases because the favorable proportion of adult females emerging from superparasitized pupa should contribute to better pest control.

Resumen en inglés

Coptera haywardi (Oglobin) is an endoparasitoid of fruit fly pupae that could find itself in competition with other parasitoids, both con- and heterospecific, already resident inside hosts. In choice bioassays, ovipositing C. haywardi females strongly discriminated against conspecifically parasitised Anastrepha ludens (Loew) pupal hosts. They also avoided pupae previously attacked by Diachasmimorpha longicaudata (Ashmead), a larval–prepupal koinobiont endoparasitoid, and the degree of larval-parasitoid superparasitism had no effect on this avoidance. There was no difference in the number of ovipositor insertions when hosts previously parasitised by a conspecific and D. longicaudata were exposed simultaneously. As females aged the degree of host discrimination declined. An ability to discriminate against pupae previously attacked as larvae suggests low levels of both conspecific and heterospecific competition in the field.

Resumen en inglés

The article examines the presence of larval parasitoids associated to anastrepha distincta in two host fruits in Chiapas, Mexico. The authors want to confirm the report that A. distincta is infesting economically important fruits such as oranges. They found younger larvae in the 12 samples of the 2 host fruits. Specifically, they discover 2 exotic species of parasitoids, Diachasmimorpha longicaudata and D. triony and 1 native species, Doryctobracon crawfordi. They conclude that the parasitizing larvae of Anastrepha distincta are present in 2 natural host fruits of the Inga genus.

Experiments were performed to determine the likely compatibility of spinosad-based GF-120 applications and mass-releases of the braconid parasitoid Diachasmimorpha longicaudata (Ashmead) for control of tephritid fruit flies. Severe effects on D. longicaudata survival and reproduction in the laboratory contrasted with mild effects in semi-field studies. Topical application and contact with dried residues on plastic surfaces in the laboratory generally resulted in high mortality of wasps and significantly reduced survival times compared to controls. Survival times of both sexes were more severely affected when exposure to dried residues on mango leaves compared to wasps that were offered GF-120 mixed with honey.

Brief (24 h) exposure to GF-120 in honey or dried residues on mango leaves did not affect total progeny production by wasps, whereas continuous exposure over a 10 d period resulted in reductions in female survival, progeny production and net fecundity (PLxMx) compared to honey-fed controls. During the rainy season, wasp survival times in field cages with young mango trees that had been sprayed with GF-120 or treated with GF-120 mixed with honey were only reduced by 1 or 2 days, respectively, compared to average 10.1 d survival of honey-fed controls. During the dry season, wasp mortality was not significantly affected by exposure to GF-120 residues on mango leaves that had been subjected to natural weathering in the field, compared to controls. Our results suggest that applications of GF-120 are unlikely to adversely influence the effectiveness of mass-releases of D. longicaudata. This prediction requires validation from comparative field studies on parasitoid populations in treated and untreated areas. 2007 Elsevier Inc. All rights reserved.

Resumen en inglés

We studied conspecific host discrimination and oviposition behavior of Diaschasmimorpha longicaudata (Ashmead), in third instar Anastrepha ludens (Loew) under laboratory conditions. The complete process of oviposition in D. longicaudata required an average of 29±11.7 s (Mean±SE), during which time the female remained completely immobile. This contrasts with attempts to oviposit for lesser durations (2-4 s), during which the female constantly moved her antennae and abdomen. In order to determine the host discrimination ability of this species (i.e., the capacity to distinguish between parasitized and non-parasitized hosts), third-instar A. ludens non-parasitized or parasitized 24 h earlier, were exposed simultaneously to individual female wasps with or without previous oviposition experience. An identical test was performed using larvae parasitized 48 h earlier. Both types of females showed a similar behavioral pattern of oviposition, but with significant differences in the number of eggs laid in parasitized and non-parasitized larvae. Experienced females showed reduced incidence of oviposition in parasitized larvae as well as a greater number of probes that did not lead to parasitism (rejection), although this difference was only significant in the 24-h test. This suggests that the host discrimination capacity of this parasitoid is innate and that previous oviposition experience increases the discrimination ability of females.

Resumen en español

Larvas de Anastrepha ludens de 8 días de edad fueron irradiadas con rayos gamma de Cobalto 60 en un intervalo de dosis de 0.5 a 7.5 Krad en un irradiador Gamacell 220 y posteriormente evaluadas como hospedero en la cría del parasitoide Diachasmimorpha longicaudata. Las larvas irradiadas se separaron en dos subgrupos, las del primer subgrupo fueron expuestas a parasitoides y las del segundo no se expusieron a parasitación. Los resultados indicaron que con 1.5 Krad se inhibió la emergencia de moscas y los parasitoides emergidos de esas larvas tratadas no presentaron una reducción en sus parámetros biológicos. Los parasitoides emergidos de las larvas irradiadas tuvieron valores de supervivencia y fecundidad similares a la que se observó en parasitoides provenientes de larvas sin irradiar. En cambio, las moscas emergidas de larvas irradiadas con 0.5 y 1.O Krad tuvieron menor fertilidad y supervivencia comparadas con las moscas provenientes de larvas no irradiadas. En la segunda etapa, se irradiaron con 2.0, 3.0 y 4.0 Krad, volúmenes de 1 litro de larva y posteriormente se evaluaron en la cría del parasitoide, en donde hubo 4.0% y 0.7% de emergencia de moscas a partir de larvas tratadas con 2.0 y 3.0 Krad, respectivamente; a 4.0 Krad se inhibió totalmente la emergencia de moscas. En la fase confirmatoria, utilizando un irradiador panorámico modelo JS-7400 con fuente de Cobalto 60, se irradiaron volúmenes de 2.5 millones de larvas en dos tiempos, el primero fue con una dosis promedio de 2.0 Krad, y el segundo hasta alcanzar 4.5 Krad. En esta etapa, para inhibir la emergencia de moscas fue necesario aplicar una dosis igual o superior a 4.5 Krad, con lo que se determinó que con esta dosis se puede irradiar larvas de A. ludens y utilizarla como hospedero para la cría de D. logicaudata sin que su calidad se vea afectada.

Resumen en inglés

In tbis research Anastrepha ludens 8-d old larvae were irradiated witb Cobalt 60 gamma rays before being offered as host of parasitoid Diachasmimorpha longicaudata. Doses used ranged from 0.5 to 7.5 Krad. The irradiated larvae were separated in two subgroups; one subgroup was exposed to D. longicaudata, while tbe second subgroup of larvae was left as control witbout exposition to tbe parasitoids. Adose of 1.5 Krad inhibited A. ludens emergence and D. longicaudata emerged from tbese treated larvae did not show any reduction in tbeir fertility and fecundity as compared witb parasitoids emerged from no irradiated larvae. Doses of 0.5 and 1.0 Krad affected the fertility and survival of A. ludens emerged from treated larvae. In a second phase, larvae were irradiated at doses of 2.0, 3.0 and 4.0 Krad per liter of larvae. Only 4.0% and 0.7% of adults emerged from larvae treated at 2.0 and 3.0 Krad, respectively. The dose of 4.0 Krad inhibited adult emergence totally. A confirmatory phase was carried out exposing to radiation 2.5 millions of A. ludens larvae at two times, during the first time larvae were irradiated at average dose of 2.0 Krad, and in the second time until adose of 4.5 Krad. The dose of 4.5 inhibited totally the flies emergence. This dose was determined as optimal for irradiating A. ludens larvae without damaging the quality of the parasitoid D. longicaudata.
