【摘要】 在红火蚁严重发生地区进行的药效试验表明,0.5%硫氟磺酰胺饵剂投放后15d药效开始发挥,25d后处理蚁巢全部死亡,药后70d调查结果显示,其对红火蚁的校正防治效果高达94.1%;0.001%氟虫腈饵剂撒施后15d开始发挥药效,30d后蚁巢中无工蚁活动,药后70d调查显示其对红火蚁的防治效果为90.9%;0.5%苯氧威饵剂撒施后40d,在蚁巢中仍能监测到工蚁的活动,70d后调查结果表明其对红火蚁的防治效果为84.9%。统计分析结果说明,0.5%硫氟磺酰胺饵剂和0.001%氟虫腈饵剂对红火蚁的防治效果好于0.5%苯氧威饵剂。由于0.001%氟虫腈饵剂和0.5%苯氧威饵剂是实验室临时配制,虽然其对红火蚁的诱食性较差,但仍能表现较好的防治效果。0.5%硫氟磺酰胺饵剂和0.001%氟虫腈饵剂可以用于红火蚁的防治,0.5%苯氧威饵剂配方需要进一步改进。更多还原

【Abstract】 The control effect of lufuhuangxianan,fipronil and fenoxycarb to red-fire ants were studied in Luchuan county,Guangxi Province.Results showed that no worker can be found when insert a stick inside fire ant mound 25 days after application of 0.5% lufuhuangxianan bait.After treated with 0.001% fipronil Bait,no worker can be found when insert a stick inside fire ant mound 30 days after application.The effects of 0.5% lufuhuangxianan bait,0.001% fipronil bait and 0.5% fenoxycarb bait to red-fire ants were 94.1%,90.9% and 84.9% respectively 70 days after application.更多还原
