Soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is an important pest that can cause significant economic damage to soybean. Synthetic insecticides are currently employed as the main management strategy to control A. glycines; however, over-use of these products has stimulated research in the development of alternative management methods, including botanical derivatives. In this study, we evaluated the bioactivity of Annona mucosa and A. muricata seed extracts and a formulation based on acetogenins (Anosom® 1 EC, 10,000 ppm) compared to the pyrethroid insecticide lambda-cyhalothrin (Warrior II®) on A. glycines. Initially, the insecticidal effect was assessed in vial bioassays and the concentration-response curves were estimated (LC₅₀/LC₉₀ for A. muricata 305.721 ppm/1290.3 ppm and A. mucosa 134.229 ppm/487.890 ppm, respectively). In the systemic effect bioassay, the same extracts were used (at 100, 500, 1,000, 5000 and 10,000 ppm), showing a reduction in the number of insects on the trifoliates. Both extracts at LC₅₀ and LC₉₀ were used in a behavior test, indicating that they are repellent and Warrior II® was attractive for the insects. The LC₉₀ rates were also used in lethal time (LT) and in greenhouse bioassays. The LT₅₀ for A. mucosa and A. muricata extracts was around 20 h. All treatments showed insect mortality rates above 65%, reaching 100% for Warrior II®, followed by the LC₉₀ of A. mucosa (92.1%). The results demonstrate the potential of Annona spp. derivatives for the management of A. glycines in soybean, and these Annonaceae-derived seed extracts could likely serve as an additional IPM tool to improve A. glycines control strategies in organic farming systems.

大豆蚜虫Aphis glycines Matsumura（半翅目：蚜科）是一种重要的害虫，可对大豆造成重大经济损失。目前使用合成杀虫剂作为控制A. glycines 的主要管理策略；然而，过度使用这些产品刺激了对替代管理方法（包括植物衍生物）开发的研究。在这项研究中，我们评估了番荔枝粘膜和A. muricata种子提取物的生物活性，以及​​一种基于多聚乙酰的制剂（Anosom® 1 EC，10,000 ppm）与拟除虫菊酯类杀虫剂 lambda-cyhalothrin (Warrior II®) 相比对甘氨酸的生物活性. 最初，在小瓶生物测定中评估了杀虫效果，并估计了浓度-响应曲线（A. muricata的 LC ₅₀ /LC ₉₀分别为305.721 ppm/1290.3 ppm 和A. mucosa 134.229 ppm/487.890 ppm）。在全身效应生物测定中，使用了相同的提取物（100、500、1,000、5000 和 10,000 ppm），表明三叶草上的昆虫数量有所减少。LC ₅₀和 LC ₉₀的两种提取物都用于行为测试，表明它们具有驱虫性，而 Warrior II® 对昆虫具有吸引力。LC ₉₀率也用于致死时间 (LT) 和温室生物测定。LT ₅₀用于A. 粘膜和A. muricata提取物约为 20 小时。所有处理均显示昆虫死亡率高于 65%，Warrior II® 达到 100%，其次是粘膜曲霉的LC ₉₀ (92.1%)。结果证明了Annona spp的潜力。用于管理大豆中甘氨酸的衍生物，而这些源自番荔枝科植物的种子提取物可能会作为一种额外的 IPM 工具来改进有机农业系统中甘氨酸的控制策略。
