The genus includes several agricultural pests globally. was reported in several countries in South America in 2013, and in Puerto Rico, in 2014. This territory is considered an agricultural hub, with a high-input system of seed production in the southern region of the island, and also at the edge of the continental U.S. Possible natural dispersion of populations of from the Caribbean or other Central American regions poses a continuing risk to the U.S. This study was performed during the post-detection scenario of in Puerto Rico, from 2018 to 2021. A year-round pheromone trapping program of adult males indicated an increase in the population from October to March and differences in the occurrence of spp. between the municipalities Juan Diaz and Salinas. The proportion of / and detection of congeneric hybrids between these species were assessed based on genital morphology and DNA analysis. Interestingly, neither nor expected hybrids were detected in the present study. The susceptibility of populations to the insecticides Spinetoram, Emamectin benzoate, Chlorantraniliprole, and Esfenvalerate was assessed, and an overall significant effect of insecticide susceptibility was detected. Chlorantraniliprole and Emamectin benzoate had the highest efficacy. These results contribute to the Integrated Pest Management and Insect resistance management programs to spp. in Puerto Rico. In addition, provide validated information to be considered in mitigation plans, in the scenario of an invasion of in the continental U.S.
该属在全球范围内包含几种农业害虫。2013年在南美洲的几个国家以及2014年在波多黎各都有相关报道。该地区被视为一个农业中心，在该岛南部地区以及美国大陆边缘拥有高投入的种子生产系统。来自加勒比地区或其他中美洲地区的该害虫种群可能的自然扩散对美国构成持续风险。本研究是在2018年至2021年波多黎各该害虫检测后的情况下进行的。一项针对成年雄性的全年性信息素诱捕计划表明，从10月到3月种群数量增加，且在胡安·迪亚兹市和萨利纳斯市之间该害虫物种的发生情况存在差异。基于生殖器形态和DNA分析评估了这些物种之间该害虫的比例以及同属杂交种的检测情况。有趣的是，在本研究中既未检测到该害虫，也未检测到预期的杂交种。评估了该害虫种群对杀虫剂多杀霉素、甲氨基阿维菌素苯甲酸盐、氯虫苯甲酰胺和乙氰菊酯的敏感性，并检测到杀虫剂敏感性的总体显著影响。氯虫苯甲酰胺和甲氨基阿维菌素苯甲酸盐的效果最佳。这些结果有助于波多黎各针对该害虫的害虫综合治理和抗虫管理计划。此外，在减轻计划中提供了经过验证的信息，以备美国大陆出现该害虫入侵的情况时参考。
