在果园叶螨的生防研究与应用中,有益螨类,特别是植绥螨(Phytoseiidae)引起国内外螨类及昆虫工作者的极大兴趣,并显示其生防应用中的重要作用。目前世界上已报道的植绥螨有800余种,分布广泛,从北极到热带均有。植绥螨大小与叶螨相近,常年同叶螨生活在一起,具有发育期短、繁殖率高、捕食叶螨量大、适应性广、抗药性强等优点,是植食性螨(如叶螨)最主要的天敌。保护和利用植绥螨是防治果园叶螨危害的一个重要方面。笔者根据国内外的研究资料和我省河西地区发现的新种益螨—银川盲走螨的初步观察资
Phytoseiidae is of great interest to mites and insect workers at home and abroad in the research and application of ornithine spider mite biocontrol, and shows its important role in biocontrol applications. At present, 800 species of phytoseiosis mites have been reported in the world and widely distributed from the Arctic to the tropical. Phytoseiidae are similar in size to spider mites and live together with spider mites all the year round. They have the advantages of short developmental period, high reproduction rate, large amount of entomopathogenic spider mites, wide adaptability and strong resistance to insecticides, ) The most important natural enemies. Protection and utilization of phytoseiid mites is an important aspect of the prevention and control of orchard mite hazards. According to the author’s research data at home and abroad and the new species of mites found in the Hexi area in our province - Yinchuan blind walking mites initial observations
