东亚飞蝗

采用毒力生物测定的方法，测定了600株从我国各地土壤和死虫等样品中分离的苏云金芽孢杆菌对东亚飞蝗的毒力。这些菌株几乎分布于已知的70个H血清型。

The toxic activities of600 Bacillus thuringiensis strains isolated from soils and dead insects in China against Locusta migratoria manilensis were analyzed by using a virulent bioassay method .

虽然有关昆虫海藻糖酶基因的研究已经比较多，大量编码海藻糖酶的cDNA序列也得到了克隆，但是东亚飞蝗作为一种世界性的农业害虫，目前尚无相关研究报道。

There have been many reports about trehalases in insects , the cDNA sequences encoding trehalase have also been cloned . The trehalase genes in locusts , a global agricultural pest , have not been studied .

分析了东亚飞蝗五龄幼虫不同组织器官Lm-TSP基因表达情况。

在准确反演LAI的基础上，根据两个时相LAI的变化进行东亚飞蝗灾害的监测，可以更准确地找出东亚飞蝗的危害范围与程度。

On the basis of retrieving LAI exactly , it was found that the range and extent of locust occurrence can be find out more exactly according to the variation between two or more LAI remote sensing data .

两个种群酶活性的差异与马拉硫磷半致死剂量（LD50）的差异很相近，这提示酯酶活性的提高在东亚飞蝗对马拉硫磷的抗性中起一定的作用。

The difference of LD_ ( 50 ) value for malathion between the two populations was consistent with the difference of esterase activities , suggesting that general esterases contributed to the malathion resistance of the two populations .

PCR一SSCP分析时，凝胶的交联度对带型的清晰程度有很大的影响，非变性聚丙烯酰胺凝胶电泳图谱显示：以α乙酸萘酯为底物染色，2个东亚飞蝗种群谱带差别不明显。

PCR-SSCP is the analysis method for denatured PCR produce in non-denaturing polyacrylamide gel electrophoresis . No distinct difference was detected in banding patterns of general esterases between the two populations , when α - naphthyl acetate was used as substrate in non-denaturing polyacrylamide gel electrophoresis ( PAGE ) .
