| 中文摘要:为解决杧果蓟马防治中药剂抗性突出、施药精度不足的问题，围绕精准施药与绿色防控技术创新，选取0.5%甲维盐·4.5%虫螨腈和1%氨基寡糖素·10%联苯菊酯·25%噻虫胺2种复配药剂，采用叶管药膜法测定其对杧果蓟马成虫的室内毒力，并利用大疆T40植保无人机开展田间飞防试验，探索优势复配药剂及无人机协同飞防应用效果。结果表明：0.5%甲维盐·4.5%虫螨腈和1%氨基寡糖素·10%联苯菊酯·25%噻虫胺对杧果蓟马均有较强毒力，LC50分别为10.72 mg/L和18.36 mg/L；混用复配药剂对杧果蓟马的杀虫活性介于2种单一复配药剂之间，LC50为14.97 mg/L。嫩梢期田间飞防试验中，0.5%甲维盐·4.5%虫螨腈施用后1 d的校正防效超过80.00%，药后3 d的校正防效可达94.97%，持效性优于其他药剂处理；药后7 d，各药剂处理对杧果蓟马的校正防效均有所降低，但仍保持在70.00%以上。表明本研究所用2种复配药剂对杧果蓟马均有较好的防效，结合植保无人机施用可用于杧果蓟马的绿色防控。 |

| Abstract:To address the prominent problems of pesticide resistance and insufficient application accuracy in mango thrips management, this study focused on innovation in precision application and green control technologies. Two compound formulations, 0.5% emamectin benzoate·4.5% chlorfenapyr and 1% oligosaccharins·10% bifenthrin·25% clothianidin, were selected, and their toxicity to adult mango thrips was determined using the leaf-tube pesticide film method. Field spray trials were conducted using the DJI T40 plant protection UAV to explore the effectiveness of dominant compound pesticides in combination with UAV-based application. The results showed that both compound formulations exhibited strong toxicity to mango thrips, with LC50 values of 10.72 mg/L and 18.36 mg/L, respectively. The insecticidal activity of the mixed compound formulation was intermediate between those of the two individual formulations, with an LC50 of 14.97 mg/L. In field trials, the 0.5% emamectin benzoate·4.5% chlorfenapyr treatment achieved a control efficacy exceeding 80.00% at one day after application and reaching 94.97% at three days post-application, showing better persistence than other treatments. Although efficacy declined by seven days after application, control levels remained above 70.00% across all treatments. These findings indicate that the two compound formulations used in this study offer effective control of mango thrips and that their integration with plant protection UAVs is feasible for green and precise management. These results provide technical support for precision pesticide application, chemical-use reduction, efficiency enhancement, and resistance management in mango cultivation. |
