In recent decades, the egg parasitoid Hadronotus pennsylvanicus (Ashmead) has gained substantial attention as an important natural enemy of pestiferous leaffooted bug species in the genera Anasa Amyot and Serville and Leptoglossus Guérin-Méneville. Throughout its native range of North America, H. pennsylvanicus parasitizes Anasa and Leptoglossus eggs in various vegetable and orchard systems. The overreliance on broad-spectrum insecticides in these systems and the demand for effective and sustainable coreid pest management strategies have motivated researchers to consider H. pennsylvanicus as an augmentative biological control agent. The potential use of H. pennsylvanicus as a classical biological control agent has also been studied in Europe in response to the rapid spread of Leptoglossus occidentalis Heidemann, an invasive pest causing significant economic losses to the European pine nut industry. Improved understanding of H. pennsylvanicus taxonomy, life history, host range, parasitoid–host ecology, laboratory rearing, and field deployment techniques have created a robust scaffold on which to build future biological control programs. This natural enemy profile reviews the current advances in the aforementioned areas of H. pennsylvanicus research and outlines the parasitoid’s prospects as a biological control agent.

Hadronotus pennsylvanicus（膜翅目：Scelionidae）：用于防治有害叶足虫（半翅目：Coreidae）的生物防治剂

近几十年来，卵寄生生物 Hadronotus pennsylvanicus (Ashmead) 作为 Anasa Amyot 属、 Serville 属和 Leptoglossus Guérin-Méneville 属有害叶足虫的重要天敌而受到广泛关注。在整个北美本土范围内，H. pennsylvanicus 将 Anasa 和 Leptoglossus 卵寄生在各种蔬菜和果园系统中。这些系统对广谱杀虫剂的过度依赖以及对有效和可持续的害虫管理策略的需求促使研究人员考虑将 H. pennsylvanicus 作为一种增强性生物防治剂。欧洲也对 H. pennsylvanicus 作为经典生物防治剂的潜在用途进行了研究，以应对西细舌鱼 (Leptoglossus occidentalis Heidemann) 的快速蔓延，西细舌鱼是一种入侵性害虫，给欧洲松子产业造成了重大经济损失。对宾夕法尼亚 H. pennsylvanicus 分类学、生活史、寄主范围、拟寄生物-寄主生态学、实验室饲养和现场部署技术的进一步了解，为构建未来的生物控制计划创建了一个强大的支架。这份天敌简介回顾了上述宾夕法尼亚州H. pennsylvanicus研究领域的最新进展，并概述了寄生蜂作为生物防治剂的前景。
