The invention belongs to the technical field of biological control of pests, is the main materials and methods for prevention of larvae of \four pests\ song of mosquitoes. Discloses a kill mosquito larvae of Bacillus thuringiensis (Bacillus thuringiensis, Bt) Bt S2160 new strain 1, the preservation number is CGMCC No.13274. The present invention relates to the insecticidal activity of strain Bt S2160 1 of Culex quinquefasciatus and Aedes albopictus larvae is high, compared with the WHO recommended Bt mosquito control strain Bti, Bt S2160 1 for Aedes albopictus larvae are more active. The invention relates to Bacillus thuringiensis Bt S2160 made 1 insecticides for large-scale prevention of Culex quinquefasciatus and Aedes albopictus larvae population. So as a powerful supplement to Bti mosquito control microorganism, can even as a substitute for Bti to control Aedes albopictus population, to reduce the risk of long-term use of Bti crystal proteins to control mosquito populations and lead to the development of resistance.
【技术实现步骤摘要】
一种杀蚊子幼虫的苏云金芽胞杆菌及其应用
本专利技术属卫生害虫的生物防治
本专利技术涉及一种对蚊子幼虫具有高效杀虫活性的苏云金芽胞杆菌菌株,涉及对该菌株基因组学的分析方法,涉及一种杀蚊子幼虫的苏云金芽胞杆菌的制备方法及在蚊子生物防治领域的应用。
技术介绍
苏云金芽孢杆菌(Bacillusthuringiensis,Bt)于1901年在日本被发现,1911年由柏林纳从地中海粉螟的患病幼虫中分离出来,并依其发现地点德国苏云金省而命名。其是一种革兰式阳性细菌,广泛分布于各种生境,是迄今为止使用最安全、最广泛的一种杀虫细菌。其发挥杀虫作用的是形成于稳定生长期的伴孢晶体(parasporalcrystalprotein),又称为杀虫晶体蛋白(insecticidalcrystalprotein,ICP),已报道ICPs对鳞翅目、双翅目、鞘翅目等各种昆虫,线虫,原生动物和癌细胞有生物活性(SchnepfE.,CrickmoreN.,RieJ.V.,etal.,Bacillusthuringiensisanditspesticidalcrystalproteins,Mic ...
