The damsel bug, Nabis pseudoferus Remane (Hemiptera: Namidae), is a generalist predator of small arthropods, including key insect pests of vegetable crops. In this study, we characterized the predation and development of various N. pseudoferus life stages when preying on the eggs and first‐ and fourth‐instar nymphs of the invasive South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). These findings were compared to those of the bug’s common prey, cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae). Of the life stages tested, females showed the highest predation rate on all tested prey, due to their high longevity, large body, and great energy requirements for reproduction. The predator’s oviposition rate was clearly influenced by prey type, and was highest when feeding on fourth instars of T. absoluta. Considering the zoophytophagy of most of the life stages of other mirid species of tomato, and the lower propensity of N. pseudoferus to feed on plants, these results show that this species can be considered as a key indigenous natural enemy for sustainable pest control packages against T. absoluta in newly invaded areas.

捕食 Tuta absoluta 的全能捕食者 Nabis pseudoferus 的捕食和繁殖

少女蝾螈（半翅目：纳米科）是小型节肢动物的全能捕食者，包括蔬菜作物的主要害虫。在这项研究中，我们描述了 N. pseudoferus 各个生命阶段在捕食入侵性南美番茄蛲虫 Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) 的卵和一、四龄若虫时的捕食和发育过程。这些发现与臭虫的常见猎物棉蚜、棉蚜（Aphis gossypii Glover）（半翅目：蚜科）的结果进行了比较。在测试的生命阶段中，雌性对所有测试的猎物表现出最高的捕食率，因为它们寿命长、体型大、繁殖需要大量能量。捕食者的产卵率明显受猎物类型的影响，以 T. absoluta 的四龄为食时产卵率最高。
