The Chinese citrus fruit fly, Bactrocera minax is one of the most economically important and aggressive pests threatening the Chinese citrus industry. In order to provide some recommendations for the improvement of integrated pest management of this species, the authors evaluated the toxicity of 6 insecticides on the second stage larvae, fourth stage larvae, and adult flies from multiple geographical B. minax populations. In addition, the influences of each pesticide on pupation and emergence were examined for one population, from Hanzhong. The 6 reagents displayed a wide range of toxicity on various stages of B. minax. Abamectin and Dichlorphos displayed the highest and lowest toxicities, respectively. All of the insecticides had negative effects on pupation and emergence of B. minax from Hanzhong, while Chlorpvrifos had the strongest impact on pupation, and Phoxim had the strongest influence on emergence. Though Phoxim and Chlorpvrifos were both effective, these insecticides belong to the class of organophosphorus pesticides, and their use should be reduced in orchards because of their high toxicity and long residual period.
中华柑桔实蝇，即蜜柑大实蝇，是威胁中国柑桔产业的最具经济重要性和侵袭性的害虫之一。为了为改进该物种的综合虫害管理提供一些建议，作者评估了6种杀虫剂对多个地理种群的蜜柑大实蝇二龄幼虫、四龄幼虫和成虫的毒性。此外，还对来自汉中的一个种群研究了每种杀虫剂对化蛹和羽化的影响。这6种试剂对蜜柑大实蝇的不同发育阶段表现出广泛的毒性。阿维菌素和敌敌畏分别表现出最高和最低的毒性。所有杀虫剂对汉中蜜柑大实蝇的化蛹和羽化均有负面影响，其中毒死蜱对化蛹的影响最强，辛硫磷对羽化的影响最强。虽然辛硫磷和毒死蜱都有效，但这些杀虫剂属于有机磷农药类别，由于其高毒性和长残留期，应在果园减少使用。
