In addition, A new mosquitocidal toxin gene was also cloned from the natural Bacillus thuringiensis. Both the intact protein and the C-terminus truncated protein had a cytoly

在E.coli中表达完整的cyt2Ba7和其3端截短的基因，发现该蛋白的C末端15个氨基酸具有保护蛋白不被降解，降低其对宿主毒性的功能。

In contrast to the wild strain, it improved the mosquitocidal toxicity,enlarged the mosquitocidal spectrum and provided a way to control the resistant mosquito.

另外，从苏云金杆菌野生株中克隆到一新的杀蚊毒素基因cyt2Ba7，其表达产物对昆虫细胞也具有溶细胞活性。

However, they have their respective shortcomings in mosquitocidal spectrum, persisting and resist-mosquito management. In this research, the mosquitocidal toxin genes cry4Ba and cry11Aa from Bacillus thuringiensis and btx gene from Bacillus sphaericus were co-expressed.cry4Aa,cry4Ba and cry11Aa genes were also co-expressed with btx gene seperatedly and in combination.The constructed recombinants had a high toxicity against susceptible and resistant mosquito.

本研究将苏云金杆菌以色列亚种的杀蚊毒素基因cry4Ba和cry11Aa与球形芽胞杆菌的二元毒素基因btx两种杀蚊菌的杀蚊毒素基因进行了重组，将Bti杀蚊毒素基因cry4Aa， cry4Ba， cry11Aa及Bs的杀蚊毒素基因btx单独或组合表达，所得工程菌株对敏感和抗性库蚊的毒力均有提高，不仅提高了杀蚊毒力，扩大了杀蚊谱，而且部分克服了蚊幼虫对Bs的抗性。

The bioassay result that the LTsoof the FWC of B-pMT9, B-pMPX2 and B-pBA30 against 3rd-4rd instar larvae of C. quinquefasciatus were 28.53 h, 17.22 h and 7.61 h respectively, indicates that the CytlAa play a key role in the synergism with Mtx 1 for faster mosquitocidal activity.
