摘　　要：1988年对新疆草原优势种蝗虫进行了利用微孢子虫病源接种防治的研究,内容包括病源活体繁殖,室内接种感染以及野外防治技术的试验。结果表明:微孢子虫对飞蝗属和星翅蝗属优势种蝗虫有明显的感受性和致病力利用飞蝗活体作为病源繁殖寄主,个体产孢量最高达1.48×10^(10),可以用于病源的商品化生产。用厚淀粉层麦麸作为毒饵病源载体,采用飞机微量撒施方法进行大面积野外试验获得了明显的防治效果。We have done research work of dominant locusts of steppe in xinjiang by adopting the Nosema Locusta pathogen inoculation control since 1988.They include those experiments that pathogen's reproduction of living-body,room inoculation infection,and field control etc. The result shows that the Nosema Locusta has apparently infecting potential and pathogentic po- tential for locust dominant.The individual quantum of spore-bearing can up to 1.48×10^(10)at most by adopting locust living-body for pathogen reproducting host and using for the commerical of pathogen.We have done field test in large areas that aerial appilication and achieved apparently control effective by adopting a thick layer of starch wheat bran for poison bait pathogen carrier.
