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

We compared the oviposition behavior and host discrimination ability of wild and mass-reared Diachasmimorpha longicaudata (Hymenoptera: Braconidae) females parasitizing Anastrepha ludens (Diptera: Tephritidae) larvae. Both kinds of parasitoid females were presented simultaneously with parasitized and non-parasitized larvae in choice tests, and their superparasitism performance was evaluated under a mass-rearing situation. At the time of the test, D. longicaudata had 156 generations under mass-rearing conditions. Our goal was to determine the effect of the mass-rearing process on the foraging decisions of this species. One of the primary findings was the apparent ubiquity of superparasitism by D. longicaudata females. Both types of females showed similar patterns in each of the phases of oviposition behavior evaluated. The only notable differences were among the percentages of transition between behaviors, mainly related to the intensity with which each activity was performed. Under a mass-rearing situation, both strains of females had a similar tendency to increase superparasitism (i.e., number of oviposition scars per puparium and the proportion of superparasitized larvae) over time. The mass-rearing process appears to have induced the selection of more aggressive, fertile and precocious females. Despite these observations, we concluded that the process of adaptation to mass-rearing conditions has not substantially influenced the foraging and ovipositional behaviors in this species.

Resumen en inglés

We analyzed the relationship among host size, superparasitism and sex-ratio in mass reared Diachasmimorpha longicaudata (Hymenoptera: Braconidae). Individual host pupae of Anastrepha ludens (Diptera: Tephritidae) were measured (length and width), and the number of oviposition scars per pupa was used as a reliable indicator of superparasitism. The probability of an emerging parasitoid being a female was positively associated with the number of oviposition scars on the host cuticle, but not with the host size. The number of scars per host pupae from which females emerged was slightly but significantly higher than in those pupae giving raise to males. In D. longicaudata, the influence of host size on sex allocation decisions of individual females seems to be overridden by the level of superparasitism, which itself was positively correlated with pupa length. This suggests that larger pupae could experience a higher number of ovipositions than their smaller counterparts, and that a high level of superparasitism may conduct to a female biased sex ratio. We discuss the relevance of these findings which could provide new elements (e.g., the manipulation of superparasitism) for optimizing the mass rearing of this parasitoid.

Resumen en español

Diachasmimorpha longicaudata (Ashmead) es un endoparasitoide de las moscas de la fruta usado como un agente de control de varias especies de Anastrepha en México. Durante la producción masiva de D. longicaudata diferentes tamaños de individuos son producidos dependiendo del tamaño del hospedero. Este trabajo investigó si el tamaño del hospedero influye sobre los parámetros biológicos y comportamentales de los parasitoides emergidos. Tres diferentes tamaños de hospederos (pequeños, medianos y grandes) fueron usados para los experimentos. El tamaño del hospedero afectó significativamente el número de parasitoides emergidos debido a que un mayor número de individuos emergió de las pupas de tamaño medio en comparación con aquellos emergidos de las pupas de tamaño pequeño y grande. La proporción de hembras/machos no fue significativamente diferente en los tres grupos. El tamaño del hospedero influyó en la esperanza de vida de los parasitoides hembras y machos sin alimento, ya que los parasitoides grandes vivieron más tiempo.

En contraste, el tamaño del hospedero no afectó la esperanza de vida de los parasitoides a los cuales se les proporcionó alimento ad libitum. El tamaño del hospedero influyó en la fecundidad de las hembras emergidas, las hembras provenientes de hospederos medianos y grandes fueron más fecundas. El tamaño del hospedero no tuvo relación con los parámetros comportamentales de los parasitoides emergidos, excepto el tiempo de aterrizaje sobre el hospedero. Las hembras provenientes de hospederas grandes tardaron menos tiempo en aterrizar en comparación con las hembras provenientes de hospederas pequeñas. El tamaño del hospedero no afectó los diferentes índices de trayectoria evaluados, excepto la velocidad promedio de caminar de D. longicaudata, las hembras provenientes de hospederos grandes mostraron un incremento en su velocidad de caminar en comparación con las hembras provenientes de hospederos chicos y medianos.

Resumen en inglés

Diachasmimorpha longicaudata (Ashmead) is an endoparasitoid of fruit flies reared for augmentative biological control of several species of Anastrepha in Mexico. During the production of D. longicaudata different sizes of parasitoids are produced depending on the host size. Here, we investigated whether host size influences the biological and behavioral parameters of the wasp that emerged under laboratory conditions. Three different sizes of host (small, medium, and large) were used for the experiments. Host size significantly affected the number of parasitoids emerged as greater number of parasitoids emerged from medium size hosts compared to small and large hosts. The ratio of females to males did not differ among the groups. Host body size influenced life expectancy of parasitoid females and males deprived of food, and parasitoids that emerged from large hosts lived longer. In contrast, host body size did not significantly influence the life expectancy of parasitoid females and males provided with food ad libitum. Host body size also affected gross and net fecundity of emerged parasitoids; females that emerged from medium and large host larvae were more fecund. Host size did not affect most of the behavioral parameters evaluated, except the time of landing on source. Females that emerged from large host larvae spent less time before landing on a host source than females from the smaller hosts. Host body size did not affect the different trajectory indices evaluated, except the mean walking speed of D. longicaudata. Females developed in large hosts showed an increase walking speed compared to females from medium and small hosts.

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.

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

Superparasitism frequency and its effects on the quality of mass-reared Diachasmimorpha longicaudata (Ashmead) parasitoids were investigated under laboratory conditions. Percentage of adult emergence, sex ratio, survival, fecundity and flight ability of adult parasitoids that emerged from Anastrepha ludens (Loew) pupae with different levels of superparasitism were determined. A high prevalence of superparasitism was observed. The number of scars per pupa, produced by insertion of the parasitoid ovipositor, ranged from 1 to 30, with an average (±SD) of 8.3 ± 6.2. Adult parasitoid emergence decreased as the level of superparasitism increased. However, the fraction of females rose with increasing superparasitism and the flight ability was lower in adults emerging from pupae with only one scar, compared with adults emerging from superparasitized hosts. Female longevity and fecundity were not affected by superparasitism. Our results support the hypothesis that superparasitism in D. longicaudata might be adaptive, since adults emerging from hosts with moderate levels of superparasitism showed the highest percentage of emergence and there were no significant differences in the other quality control parameters tested. Our findings are relevant to the mass rearing process, where the ratio of hosts to parasitoids can be optimized as well as the distribution of eggs deposited in host larvae. This contributes to efficient mass rearing methods for augmentative biological control programs.

Resumen en español

El superparasitismo de Diachasmimorpha Iongicaudata (Ashmead), en larvas de Anastrepha ludens (Loew) y su efecto sobre la calidad del parasitoide obtenido fue determinado bajo condiciones de laboratorio en este trabajo. Los parasitoides adultos fueron evaluados de forma individual en los parámetros de emergencia y proporción sexual, supervivencia y fecundidad, mientras que para evaluar habilidad de vuelo se fijaron rango de número de cicatrices de acuerdo a su probabilidad de encuentro en cría masiva. La cría masiva presentó altos niveles de superparasitismo, encontrando desde 1 hasta 30 cicatrices de oviposición en el hospedero. La emergencia de parasitoides adultos se vio afectada significativamente en relación al número de cicatrices de oviposición presentes en el hospedero del cual provenía. La relación sexual de los adultos emergidos estuvo basada en hembras, siendo mucho mayor en pupas con un alto número de cicatrices de oviposición, mientras que en pupas con una sola cicatriz ésta estuvo basada en machos. La longevidad bajo dos condiciones (con alimento y sin alimento) y la fecundidad no se vio afectada en los adultos que provinieron de pupas con diferente número de cicatrices de oviposición. La habilidad de vuelo se vio afectada significativamente en los adultos provenientes de hospederos con una sola cicatriz de oviposición. En contraste los adultos provenientes de pupas de 2 ó más número de cicatrices de oviposición no presentaron diferencias significativas, siendo buenos voladores. Nosotros discutimos y evaluamos si el superparasitismo de D. Iongicaudata, endoparasitoide solitario es adaptativo, favoreciendo los parámetros biológicos del adulto emergido.
