BsC3-41 mosquito larvae in emulsion;Culex pipiens pallens;Culex tritaeniorhynchu;control effect

Habitat areas & habitat types and the main mosquito species in Karamay areas,agricultural development zone,Baijiantan area,Wurhe area were preliminarily studied.Habitat areas are totally approximate 33 km2;they are mainly distributed in Jiugongli,agricultural development zones,water fish ponds,sewage treatment plant,Karamay oil refineries,oil test,Baijiantan Landfill,Shuiniu Park,Zuanjing Park,etc.;the main habitat types are wetlands,sewage eliminate.Experiments were made on using BsC3-41 against the larvae of Culex pipiens pallens and Culex tritaeniorhynchu in the laboratory and field in Xinjiang.It used five different densities in the laboratory and one density in the field.The control rate of BsC3-41 mosquito larvae in emulsion are 100% after 24-48 hours.The LC50 of Culex pipiens pallens is 0.015 6 ug·g-1.The 95% certainty factor varied from 0.008-0.002 74 ug·g-1.The LC95 is 0.450 7 ug·g-1.The LC50 of Culex tritaeniorhynchu is 0.018 5 ug·g-1.The 95% certainty factor varied from 0.009 5 to 0.035 7ug·g-1;the LC95 is 0.930 4 ug·g-1.
