摘　　要：为明确广西南宁豇豆蓟马种群动态发生规律并筛选出豇豆蓟马防治药剂,调查豇豆蓟马数量以及在植株不同部位的分布,并开展了9种杀虫剂的田间药效试验。结果表明,蓝板诱集数量的高峰在5月下旬至6月初和6月下旬,对植株不同部位的调查表明,蓟马对花具有偏好性,种群数量高峰期与盛花期重叠,花谢后部分蓟马转移到豆荚上,种群数量有所下降。田间药剂试验筛选出了60 g·L^(-1)乙基多杀菌素SC和6%联苯菊酯·啶虫脒ME等两种防效显著的杀虫剂,药后1d防效分别为82.0%和73.4%,持效期为7~10d,可以轮换使用,用于豇豆蓟马的田间防治。In order to clarify the population dynamics of cowpea thrips in Nanning,Guangxi and screen out insecticides with better control effect,a survey was conducted to investigate the number and distribution of cowpea thrips in different plant parts through blue plate trapping,and field trials of 9 insecticides were carried out.The peak number of blue plate traps were late May to early June and late June.Surveys of different parts of the plant showed that cowpea thrips have a preference for flowers,representing the peak date of the population overlapped with the full blooming period.Then,some thrips transferred to the beans after flowering,resulting in a decrease in the population.Two insecticides with significant control effects,including 60 g·L^(-1) ethyl polysulfide SC and 6%bifenthrin·acetamiprid ME,were selected in the field pes-ticide experiment.The insecticides had a control effect of 82.0%and 73.4%after 1 day of treatment,respectively,and had a duration of 7-10 days,which can be used alternativey for field control of cowpea thrips.
