ABSTRACT Life history and damage potential of the fruit fly, Dacus persicus Hendel, a prospective biological control agent for calotrope, Calotropis procera (Aiton) W.T. Aiton, are described. The duration of life cycle of D. persicus (egg to the adult) was 42.2 ± 0.38 days (range 38–50 days). Oviposition commenced 5.1 ± 0.2 days after emergence and each female infested 4.5 ± 0.2 fruits during its lifespan. D. persicus produced 76.9 ± 5.21 larvae from which 66.1 ± 3.7 adults emerged with a sex ratio of 4:3 female to male. The lifespan of adults was 16.3 ± 0.68 days. The fruit fly larvae destroyed 100% of immature seeds in infested pods and significantly reduced the biomass of infested fruits by 62%. The field host specificity, high reproductive capacity, and damage potential of D. persicus indicate this species as a potential biological control of C. procera in Australia.

果蝇 Dacus persicus（双翅目：Tephritidae）的生物组学和潜在损害：Calotropis procera（夹竹桃科）的前瞻性生物防治剂

摘要描述了果蝇 Dacus persicus Hendel 的生活史和损害潜力，这是一种用于 calotrope 的前瞻性生物防治剂 Calotropis procera (Aiton) WT Aiton。D. persicus 生命周期的持续时间（从卵到成虫）为 42.2 ± 0.38 天（范围 38-50 天）。产卵在出苗后 5.1 ± 0.2 天开始，每只雌性在其一生中侵染 4.5 ± 0.2 个果实。D. persicus 产生了 76.9 ± 5.21 只幼虫，其中 66.1 ± 3.7 只成虫出现，雌雄比例为 4:3。成年人的寿命为 16.3 ± 0.68 天。果蝇幼虫破坏了受侵染豆荚中 100% 的未成熟种子，并使受侵染果实的生物量显着减少了 62%。D. 田间寄主专一性、繁殖能力强、危害潜力大。
