摘　　要：为筛选高效安全的花生种衣剂,选用7种杀虫剂对暗黑鳃金龟进行室内毒力测定,并在此基础上,复配杀菌剂戊唑醇或吡唑醚菌酯制成种衣剂开展田间防效试验。室内毒力测定结果表明,供试的7种杀虫剂原药中,联苯菊酯、噻虫胺和氯虫苯甲酰胺对7日龄暗黑鳃金龟幼虫的毒力较高,96 h的LC_(50)依次为0.490、12.923和14.705 mg/kg。田间防效结果表明,添加杀菌剂戊唑醇或吡唑醚菌酯复配后处理,出苗率、防治效果、保果效果和增产率均得到进一步的提高,其中以12%联苯菊酯·吡唑醚菌酯和12%联苯菊酯·戊唑醇的综合防效最佳,可作为花生病虫害防治的轮换药剂推广应用。In order to screen efficient and safe seed coating agent for peanut,seven insecticides were selected for laboratory toxicity test of Holotrichia parallela.On this basis,the fungicide tebuconazole or pyraclostrobin was mixed into seed coating agents and the field control experiments were carried out.The laboratory toxicity test results showed that among the 7 pesticides tested,bifenthrin,clothianidin and chlorantraniliprole had higher toxicity to 7-day-old larvae of Holotrichia parallela,and the LC_(50) at 96 hours were 0.490 g,12.923 and 14.705 mg/kg,respectively.Field experiments showed that the emergence rate,control effect,fruit preservation effect and yield increase rate were further improved after adding the fungicide tebuconazole or pyraclostrobin.Among them,12%bifenthrin·pyraclostrobin and 12%bifenthrin·tebuconazole had the best comprehensive control effect,and could be used as rotation agents for peanut diseases and pest control.
