Domestication‐related changes in sexual performance of Queensland fruit fly

Abstract: In Sterile Insect Technique (SIT) programs, massive numbers of insects are reared, sterilized, and released in the field to impede reproduction of pest populations. The domestication and rearing processes used to produce insects for SIT programs may have significant evolutionary impacts on life history and reproductive biology. We assessed the effects of domestication on sexual performance of laboratory reared Queensland fruit fly, Bactrocera tryoni, by comparing an old (49 generations) and a young colony (5 g… Show more

“…Of particular relevance here, studies of B. dorsalis , A. ludens and C. capitata have found, as in the present study, that the level of remating inhibition declines during domestication 51 , 56 , 57 . On the other hand, the one precedent for Qfly, by Pérez et al 62 , did not find this pattern. That study compared two strains from the same locality (Brisbane), one after five and the other after 49 generations in the laboratory.…”

“…Similar to A. ludens , changes in the level of remating inhibition might be expected during Qfly domestication, because domestication effects have been described for other reproductive behaviours and the (nutrient-dependent) development of both sexes’ reproductive organs 61 , 62 . However, a recent comparison of old (Generation 49) and young (Generation 5) Qfly colonies from Brisbane, Australia, found similar levels of remating inhibition in all combinations of males and females from the two colonies 62 .…”

“…The Z. cucurbitae base population that underwent selection was a mass-reared strain that was maintained at the Okinawa Prefectural Pest Control Technology Center, Okinawa, Japan, according to the methods described by Nakamori & Kakinohana (1980) and Nakamori et al (1992). The strain originated in 1985, with 19281 larvae gathered from bitter gourd fruits, Momodrica charantia L. (Cucurbitaceae), collected in the southern part of Okinawa Island, Japan (Kakinohana, 1996).…”

“…All rearing activities and experiments were conducted in a laboratory at 25 AE 2°C and L14:D10 photoperiod (light phase: 05:30-19:30 hours). Approximately 2400 eggs (0.3 ml) from each line were placed on 300 g of artificial larval medium (Nakamori et al, 1992) in a sample container (7.7 cm high, 13 cm diameter). Each cup was kept separately in a larger sample container (9.2 cm high, 15 cm diameter) filled with water (80 ml).…”
