应用0.5%硫氟磺酰胺颗粒毒饵(一扫清)对红火蚁进行毒饵防治,分别用陷阱法、碟诱法和目测法调查防治前、后蚁群的密度、活动数量及空巢率,并评估防治效果。结果表明,陷阱法和目测法调查,投饵后20～30d防效可达100%,而碟诱法调查,防效达100%的时间是60d左右。试验还显示,一次饱和性投饵的防效更可靠,可避免中毒后复活的蚁群在再次投饵时拒食。
The poison bait was applied to 0.5% thio-sulfur sulfonamide particles (one cleared away). The density, number of activities and empty nest rate of the ant before and after the ant-control were investigated by trap method, disk induction method and visual inspection method respectively Evaluation of control effects. The results showed that the trap method and visual inspection survey, 20 ~ 30d after the bait control effect of up to 100%, while the dish induced law investigation, control effect of 100% of the time is 60d or so. The test also showed that the control of one saturation feeding was more reliable, which could prevent the ant remodeling after poisoning from refusing to feed again.
