An increase in international trades in goods and services and the movement of humans in recent decades has led to a concomitant increase in the number of exotic insects invading new areas, with some establishing as harmful agricultural pests. That is how the South American tomato pinworm, Tuta absoluta (Lepidoptera: Gelechiidae) has recently and rapidly invaded Niger except the Diffa region. This new pest represents a real threat for tomato production in the country. To this end, the first step includes identifying the fortuitous natural enemies present. For this purpose in Niger, five tomato-infested fields from three distant and climatically different agricultural regions were sampled, with a particular focus on predatory mirids. Based on morphological characters and molecular barcoding approach, Nesidiocoris tenuis, N. volucer and N. callani (Miridae: Dyciphini) were reported for the first time in Niger and associated with tomato pests providing new insights upon their distribution areas and ecology, and genetic diversity. These findings are discussed in the framework of T. absoluta management and also the need of accurately identifying the community of natural enemies when facing invasive species.

首次报道在尼日尔被南美番茄蛲虫侵染的番茄田中的三种掠食性昆虫（异翅目：蛲虫科）：生物控制的机会？

近几十年来，国际商品和服务贸易的增加以及人类的流动导致入侵新地区的外来昆虫数量随之增加，其中一些被确定为有害的农业害虫。这就是南美番茄蛲虫 Tuta absoluta（鳞翅目：Gelechiidae）最近迅速入侵尼日尔（迪法地区除外）的方式。这种新的害虫对该国的番茄生产构成了真正的威胁。为此，第一步包括确定存在的偶然天敌。为此，在尼日尔，对来自三个遥远且气候不同的农业区的五个番茄出没的田地进行了采样，特别关注掠食性蝾螈。基于形态特征和分子条形码方法，细小猪笼草、卷毛猪笼草和 N. callani (Miridae: Dyciphini) 首次在尼日尔被报道并与番茄害虫相关联，为它们的分布区域和生态以及遗传多样性提供了新的见解。这些发现在 T. absoluta 管理的框架内进行了讨论，并且在面对入侵物种时也需要准确识别天敌群落。
