Abstract:
  •      [Objectives]  Pachycrepoideus vindemmiae is a parasite of fruit flies that is an important biological control agent of these pests. Whether this parasitoid can be reared on housefly pupae was investigated. [Methods]  The host preferences of parasitoids reared on housefly or fruit fly pupae were compared. The offspring size, longevity, oviposition duration, productivity, and offspring sex ratio from females reared on these two types of hosts were also compared. [Results]  Housefly pupae were significantly larger than fruit fly pupae, and parasitoids that developed from housefly pupae were also larger. The longevity, oviposition duration, number of offspring per female of female parasitoids reared on housefly and fruit fly pupae were (13.4 ± 4.11) and (3.94 ± 2.49) d, (11.4 ± 4.11) and (3.13 ± 2.42) d, (34.31 ± 31.83) and (7.88 ± 3.58), respectively. The host preferences of parasitoids reared on the two kinds of hosts were similar. [Conclusion]  The results suggest that P. vindemmiae reared on housefly pupae were healthier than those reared on fruit fly pupae, and that housefly pupae are suitable hosts for rearing P. vindemmiae for the control of fruit fly pests in waxberry orchards.
