Doryctobracon areolatus (Szépligeti), a solitary endoparasitoid native to the Neotropics, attacks eggs and early instar larvae of Anastrepha fruit flies, and can enter diapause under tropical and subtropical conditions. We aimed to test if biological attributes, such as size, flight ability, starvation resistance, longevity and fecundity of diapausing individuals differ from those of non-diapausing ones. Parasitoids were obtained from a laboratory colony reared on Anastrepha ludens (Loew) larvae. Parasitized host puparia were sorted in two cohorts according to their diapause condition. Developmental time from egg to adult ranged from 18 to 31 days in non-diapausing parasitoids, and 70 to 278 days for diapausing individuals. Pupal weight and adult measurements were higher in non-diapausing than in diapausing parasitoids. There were no differences in adult longevity, starvation resistance, and emergence between diapausing and non-diapausing wasps. Flight ability and fecundity rates were greater in the non-diapausing than in the diapause cohort. The proportion of female offspring was greater in the non-diapausing cohort (42.5%), whereas in the diapausing cohort the male offspring proportion was greater (62.4%). Both cohorts produced diapause offspring, but the non-diapausing cohort produced more (26.6%) than the diapausing one (9.1%). Maternal age had a significant effect on the proportion of diapause offspring: in 26 to 34 days old non-diapausing females, 78.9% of their offspring entered into diapause. These results confirmed that diapause affects the JHR 78: 41–56 (2020) doi: 10.3897/jhr.78.52269 http://jhr.pensoft.net Copyright Jassmin Cruz-Bustos et al.

滞育和非滞育 Doryctobracon areolatus（膜翅目，甲壳虫科）的生物学特性，一种按实蝇属的寄生物。（双翅目，实蝇科）果蝇

Doryctobracon areolatus (Szépligeti) 是一种原产于新热带地区的孤立内寄生物，攻击按实蝇的卵和早龄幼虫，并且可以在热带和亚热带条件下进入滞育期。我们旨在测试滞育个体的生物属性，如大小、飞行能力、抗饥饿性、寿命和繁殖力是否与非滞育个体不同。拟寄生物是从用按实蝇 (Loew) 幼虫饲养的实验室菌落中获得的。寄生的寄主蛹根据滞育条件分为两组。非滞育寄生蜂从卵到成虫的发育时间为 18 至 31 天，滞育个体为 70 至 278 天。非滞育的蛹重量和成虫测量值高于滞育的寄生蜂。滞育和非滞育黄蜂在成虫寿命、抗饥饿性和出现方面没有差异。非滞育队列的飞行能力和繁殖率高于滞育队列。在非滞育队列中，雌性后代的比例更高（42.5%），而在滞育队列中，雄性后代的比例更高（62.4%）。两个队列都产生了滞育后代，但非滞育队列产生的后代 (26.6%) 多于滞育队列 (9.1%)。母龄对滞育后代的比例有显着影响：在26～34天龄的非滞育雌性中，78.9%的后代进入滞育状态。这些结果证实滞育影响 JHR 78: 41–56 (2020) doi: 10.3897/jhr.78.52269 http://jhr.pensoft.net 版权所有 Jassmin Cruz-Bustos 等。这是一篇根据知识共享署名许可 (CC BY 4.0) 条款分发的开放获取文章，该许可允许在任何媒体中不受限制地使用、分发和复制，前提是注明原作者和来源。研究文章 Jassmin Cruz-Bustos 等人。/ 膜翅目研究杂志 78: 41–56 (2020) D. areolatus 的 42 种生物学属性。观察到的差异有助于更好地了解滞育对该物种的定殖和饲养过程及其作为生物防治剂的用途的影响。/ 膜翅目研究杂志 78: 41–56 (2020) D. areolatus 的 42 种生物学属性。观察到的差异有助于更好地了解滞育对该物种的定殖和饲养过程及其作为生物防治剂的用途的影响。/ 膜翅目研究杂志 78: 41–56 (2020) D. areolatus 的 42 种生物学属性。观察到的差异有助于更好地了解滞育对该物种的定殖和饲养过程及其作为生物防治剂的用途的影响。
