摘　　要：竹醋液是竹炭加工过程中的副产品,为纯天然产品,在农业上有着广泛的应用。本文在室外笼罩环境下研究了竹醋液对豆株上西方花蓟马成虫的忌避作用。结果显示:竹醋液的不同浓度和同一浓度下的不同处理时间,对西方花蓟马成虫的忌避作用有显著差异。浓度增加显著地提高了竹醋液对西方花蓟马成虫的忌避作用,而忌避作用随时间的延长而逐渐降低。质量分数为2.06%和1.03%的竹醋液对西方花蓟马成虫有明显的忌避作用,前者在使用后10d时其忌避显著下降。本文同时探讨了竹醋液在西方花蓟马控制上应用的可能性。Deterrent effect of bamboo vinegar to western flower thrips was studied in caged bean plants. The results showed that there were significant differences in deterrent effect of bamboo vinegar to western flower thrips, when bean plants were treated with different concentrations of bamboo vinegar and varying time after sprays. Deterrent effect increased strikingly with the increasing concentrations of bamboo vinegar and diminished with prolonged appli- cation time. Bamboo vinegar at the concentration of 2.06% and 1.03% has an obvious deterrent effect on thrips a- dults, and this effect could last for 10 days at the former concentration. It was also discussed, in this study, about the possibilities of whether bamboo vinegar could be used in controlling western flower thrips.
