西方盲走螨(Typhlodromus occidentalis Nesbitt)是果树上害螨的重要捕食螨。美国、澳大利亚等一些国家,利用西方盲走螨防治果园中害螨已获得了一定的成效。为了弄清该螨从国外引进后的适应性及利用的可能性,1981年我们在室内外对该螨的一般生物学特性进行了观察。 Typhlodromus occidentalis Nesbitt is an important predatory mite on fruit trees. Some countries, such as the United States and Australia, have achieved some success by using blindly riddled western mites to control pest mites in orchards. In order to understand the adaptability and utilization of the mite after its introduction from abroad, we observed the general biological characteristics of the mite indoors and outdoors in 1981.
