摘要
生物防治工作者需要证明，候选制剂不仅可以安全释放，而且会在其新的分布区广泛建立，对目标杂草产生重大影响。我们在隔离区进行了这项研究，以深入了解 2023 年初释放的食根跳甲虫 Heikertingerella sp.（Chrysomelidae）对南非入侵树木 Tecoma stans (L.)（Bignoniaceae）的影响和分布情况。我们研究了低密度和高密度甲虫对植物生长和生物量以及甲虫 F1 代后代产量的影响。与对照组相比，受到甲虫影响的植物的生长和生物量积累明显减少。在甲虫密度较高的情况下，P1 成虫破坏的小叶明显较多，F1 后代的产量也明显较高。MaxEnt 模型的预测结果表明，南非大部分地区的气候非常适合 Heikertingerella sp.甲虫的热生理学由其临界最低和最高热温度以及致死温度（LT50）的下限和上限决定，这表明在南非属于 T. stans 范围的八个省份中，至少有四个省份对极端温度具有耐受性。我们的研究结果进一步证明了在南非适宜地区释放 Heikertingerella sp.
Predicted impact, establishment and distribution of Heikertingerella sp. (Coleoptera, Chrysomelidae), recently released for the biological control of Tecoma stans in South Africa
Impacto, establecimiento y distribución previstos de Heikertingerella sp. (Coleoptera, Chrysomelidae), liberado recientemente para el control biológico de Tecoma stans en Sudáfrica
期刊介绍：
Agricultural and Forest Entomology provides a multi-disciplinary and international forum in which researchers can present their work on all aspects of agricultural and forest entomology to other researchers, policy makers and professionals.
The Journal welcomes primary research papers, reviews and short communications on entomological research relevant to the control of insect and other arthropod pests. We invite high quality original research papers on the biology, population dynamics, impact and management of pests of the full range of forest, agricultural and horticultural crops.
