Abstract

Abstract Podisus distinctus (Stäl, 1860) (Heteroptera: Pentatomidae) is a predator of defoliating caterpillars of Eucalyptus spp. (Myrtaceae). This South-American asopine can be reared in the laboratory using Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae) pupae as alternative prey and released in the field. The movement observed in T. molitor pupae can be a defensive strategy. This makes it significant to study the development and reproduction of asopine predatory stinkbugs using transected pupae of this prey. The aim was to evaluate the performance of P. distinctus with transected or non-transected T. molitor pupae in the laboratory. The ventral nerve cord of T. molitor pupae was transected utilizing surgical forceps (T1, transected pupae), while the control included non-transected pupae (T2, non-transected pupae). These pupae were offered to P. distinctus nymphs and adults. We evaluated the duration and body mass of instars III, IV and V; duration from instar V to the adult stage; body mass of the newly emerged adults; adult sex ratio; total number of egg masses, eggs per female and egg mass; total nymphs per female and egg mass; percentage of nymphs hatched; female longevity, and the pre-oviposition, oviposition and post-oviposition periods of this predator. The body mass of P. distinctus adults was 7.29% greater with the non-transected T. molitor pupae; however, the other parameters showed similar values between treatments. Non-transected T. molitor pupae are preferred for rearing the predator P. distinctus.

异足虫(异翅目:蝽科)雌性以腹侧神经索横断的黄粉虫(鞘翅目:黄粉虫科)蛹为食

摘要:独特足鼠(Stäl, 1860)(异翅目:蝽科)是桉属(桃科)落叶毛虫的捕食者。该南美小飞蛾可在实验室饲养，使用tenbrio molitor L.， 1758(鞘翅目:tenbrio molitor L.)的蛹作为替代猎物，并在野外放生。在T. molitor蛹中观察到的运动可能是一种防御策略。这使得利用该猎物的横切蛹研究asopine掠食性臭虫的发育和繁殖具有重要意义。目的是在实验室中评价不同斑胸小蠊与横切或未横切斑胸小蠊蛹的繁殖性能。采用手术钳横切侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳侧耳。这些蛹被提供给p.p distinctus若虫和成虫。我们评估了III、IV和V星的持续时间和体重;从V星到成虫期的持续时间;新生成虫的体重;成人性别比;卵团总数、每只雌卵数和卵团数;每只雌虫的若虫总数和卵量;孵化的若虫百分比;雌性寿命，以及这种捕食者的产卵前、产卵期和产卵期。与未横切的褐家鼠蛹相比，褐家鼠成虫体质量大7.29%;然而，其他参数在处理之间显示相似的值。未横切面的褐斑田鼠蛹更适合饲养捕食者褐斑田鼠。
