摘要
采用1.393 nmol/L 和0.697 nmol/L 两种低浓度奋斗呐药液处理嗜人按蚊4龄幼虫,从其羽化后2～3 d 的雌、雄成蚊收集血淋巴.应用 ICAP-9000型等离子原子发射光谱仪测定成蚊血淋巴中的铁、铜、锌、锰、铬等必需微量元素的含量。结果表明,随药物浓度增高,铁、锌、锰和铬的含量均增加,铁和锌有非常显著性差异(P<0.01);尤其是两种浓度用药组的蚊血淋巴中铁、铜、铬和锰4种微量元素含量均较对照组(去氯水)蚊为高,其中铁、铜、铬有非常显著性差异。提示经低浓度奋斗呐处理嗜人按蚊4龄幼虫后,可影响蚊成虫血淋巴某些微量元素的含量.
The fourth instar larvae of Anopheles arthropophagus were treated with two low dosages(1.393nmol/L and 0.697nmol/L)of fendona,and the hemolymph was collected from 2～3 days after male and female mosquitoes.The amounts of trace elements,such as iron(Fe),zion(Zn),eupper(Cu),mangamese(Mn)and cromium(Cr)were detected by cou- pled plasma emission spechrometer(ICAP).The amounts of Fe,Zn,Mn and Cr increased with the concertration of fendona increase,Fe and Zn were with striking significant differ- ence(P<0.01).Especially showed the components of the five trace elements in hemolymph of two treated groups mosquitoes were more than the control groups.The results showed that the low dosages of fendona could influence on the amounts of some kinds of trace ele- ments in Anopheles arthropophagus adults,which emerged from instar larvae treating with the drug fluid.
