“…Comparisons of the survival curves of the different populations reared on artificial diet showed that the maximum longevity of both females and males was greater for Lab-Pop than for Hybrid-Pop. These results are in agreement with other studies involving species in which a reduced survival in wild populations reared on an artificial diet has been found (Leppla 1983, Economopoulos 1992, Ekesi et al 2007.…”

ABSTRACT.The healthy maintenance of insects reared under laboratory conditions requires strategies to retain the natural characteristics of their life-histories traits. Rearing strategies include artificial selection to laboratory conditions, hybridization with compatible strains, and supplying the colony with wild individuals. We compared behavioral as well as life-history aspects of two laboratory strains of Ceratitis capitata Wiedemann (Diptera, Tephritidae) that had either been reared for 15-20 years under laboratory conditions with or without introducing wild specimens (Lab-Pop and Hybrid-pop, respectively). The parameters evaluated were: performance and food ingestion of immatures, adult size and longevity, female oviposition preference and fecundity, egg viability, and mating choice. Analyses of these parameters were conducted under laboratory rearing conditions. The largest differences observed between the two strains were related to behavioral components: food ingestion rate at the larval stage and oviposition behavior. In general, Lab-Pop individuals were less selective and more adapted to the artificial diet than Hybrid-Pop individuals (diet consumption), but there were no significant differences between the two strains in terms of percentage of emergence, egg viability, adult size, fecundity, and mating choice. It is suggested that the use of hybrid strains is more appropriate than the use of strains without the incorporation of wild individuals, especially in studies that involve behavioral parameters, as hybrid strains behave very similarly to wild populations, according our previous studies. Key words: fruit flies, laboratory rearing, feeding behavior, life history. insectos incluyen selección, hibridación con linajes compatibles y suministro a la colonia con individuos silvestres. Para investigar este último punto, comparamos los aspectos comportamentales así como los aspectos de las historias de vida de dos colonias de laboratorio de Ceratitis capitata Wiedemann (Diptera, Tephritidae) que han sido criadas entre 15 y 20 años en condiciones de laboratorio sin introducir ejemplares silvestres (Lab-Pop), o con introducciones ocasionales (Hybrid-Pop). Los parámetros evaluados fueron: el desempeño y la tasa de ingesta larval, el tamaño y la longevidad de los adultos, la preferencia de oviposición y fecundidad de la hembra, la viabilidad del huevo, y la elección para el apareamiento. Se realizaron análisis de estos parámetros bajo condiciones de cría con una dieta artificial. Las mayores diferencias entre individuos de las dos colonias se registraron en variables comportamentales: tasa de ingesta larval y comportamiento de oviposición. En general, la colonia LabPop fue menos selectiva y más adaptada a la dieta artificial que la colonia Hybrid-Pop (consumo de la dieta), pero no hubo ninguna diferencia significativa entre las dos poblaciones en el porcentaje de emergencia, la viabilidad del huevo, el tamaño de los adultos, la fecundidad, y éxito en el apareamiento. Se sugiere que el uso de colonias híbri...

“…For Ceratitis capitata (Wiedemann), Leppla et al (1983) explained the precipitous decline in yield during the Þrst generation as following a change from natural host to artiÞcial mass-rearing methods, indicating that this method is inadequate. Ekesi et al (2007) observed that pupal recovery increased throughout the generations during the colonization of Bactrocera invadens Drew, Tsuruta & White. This trend could be explained by the fact that colony founders are forced though genetic bottlenecks to eliminate variability as well as phenotypes that prevent adaptation to the larval diet.…”

Demographic Changes in <I>Anastrepha obliqua</I> (Diptera: Tephritidae) Throughout the Laboratory Colonization Process

The demographic changes in Anastrepha obliqua (Macquart) (Diptera: Tephritidae) throughout laboratory colonization were characterized over the course of 11 generations. Four significant changes were determined. The first change was a reduction in the preoviposition period from the G(p) to G(1). The second was that wild female flies had difficulty ovipositing in an artificial substrate, yielding the lowest fecundity rates observed throughout the experiment. The third significant change was a decrease in longevity and life expectancy from G(p) to G(1), which then continued to decrease with successive generations. This resulted in a lab strain with high fecundity limited to a short period of oviposition. The last significant change was a reduction in larval and pupal weight. In addition, larval recovery decreased from G(p) to G(1) but displayed rapid recovery over the course of generations. There was no change in adult emergences for all generations, and flight ability increased with successive generations. These changes were correlated with demographic parameters, indicating that the increased investment in early age reproduction incurs costs such as a reduction in life expectancy or fecundity later in life. This trend was also correlated with an increase in early fecundity and reduction in the oviposition period.

“…Even after nine generations, the fecundity of wild C. capitata did not match the levels of laboratory-adapted flies (Economopoulos, 1992;De Souza et al, 1988) and Bactrocera cucurbitae (Coqillett) required 14 generations to reach a stable oviposition plateau (Kamikado et al, 1987). In the olive fruit fly, approximately three to four generations were required to adapt (Tsitsipis, 1983) and Bactrocera invadens adapted to an artificial diet in three to five generations (Ekesi et al, 2007). In some cases, attempts to colonize a wild population on artificial diets have failed (Rössler, 1975).…”

The olive fly Bactrocera oleae (Rossi) is the key pest for olive cultivation worldwide. Substantial effort has been invested in the development of the sterile insect technique (SIT) to control this pest. One of the limitations to develop SIT technology for olive fruit fly is the low ability of wild females to lay eggs in other medium than olive fruits, and their slow adaptation to oviposition in artificial substrates. In the present study, fruit grapes were used as an alternative egg collection medium to harvest eggs and young larvae from freshly colonized wild strains originating from France, Italy, Spain and Croatia. The larvae were allowed to develop into the fruits until the second instar, before they were extracted out and further reared on a standard artificial diet. Furthermore, F1 to F4 female flies were alternatively offered wax bottles to oviposit. Finally, the performance of hybrid strains created from crosses between wild and long colonised flies was assessed. The results showed that females of all 4 wild strains readily oviposited eggs in grapes and from the F2 generation onward, females from all strains were adapted to laying eggs in wax bottles. No difference was observed in eggs and pupae production among all strains tested. The findings are discussed for their implications on SIT application against olive fruit fly.
