中文摘要:
      红火蚁 Solenopsis invicta Buren 是一种重要的入侵害虫,可对农林生产、人体健康等造成严重威胁。毒饵诱杀是红火蚁防治的重要措施,高效的红火蚁毒饵有效成分需要通过胃毒测试筛选获得,而用于测试的胃毒药剂的 配制则需借助对红火蚁微毒或无毒性的助溶剂。本文通过糖水饲喂法研究了不同剂量丙酮、吐温 20、吐温 80、二甲基亚砜和 Triton X100 对红火蚁存活、取食以及运动的影响。结果表明,2% 和 10% 吐温 80、1% 和 5% 吐温 20、 5% 二甲基亚砜、2% 和 10% 的 Triton X100 严重影响红火蚁的存活并影响其取食行为,1% 二甲基亚砜溶液处理 10 d 后会降低工蚁存活率,而 2% 丙酮溶液、10% 丙酮溶液处理不会对红火蚁的存活和行为产生负面影响。研究发 现,2% 和 10% 丙酮对红火蚁没有毒性,可作为红火蚁胃毒药剂筛选的助溶剂。
英文摘要:
      Red imported fire ant,Solenopsis invicta,is an important invasive species and is a threaten to human health,agriculture,public health,and ecology in its introduced regions. Application of toxic bait is one of key methods for fire ant management. It is important to screen effective pesticides with high gastric toxicity against fire ant. Since many pesticides are water-insoluble,it is necessary to choose solvents with little or no toxic effects on S. invicta for gastric toxicity test of pesticides. In the present study,laboratory tests were done to determine toxicity of five common solvents,i.e. acetone,Tween 20, Tween 80,dimethyl sulfoxide,and Triton X100 on S. invicta. The results revealed that 1% Tween 20, 5% Tween 20,2% Tween 80,10% Tween 80,1% dimethyl sulfoxide,5% dimethyl sulfoxide,2% Triton X100,and 10% Triton X100 had negative effects on S. invicta survive and behavior. Acetone at 2% and 10% concentrations did not cause any negative impact on S. invicta. So,acetone at 2% and 10% could used in gastric toxicity test of pesticides against S. invicta.
