【摘要】 对新疆地区啤酒花上的土耳其斯坦叶螨 Tetranychus turkestani Ugarov et Nik-lski 的生物学、发生特点及防治对策进行了初步探讨。该螨寄丰广,为害啤酒花叶片和球果。在啤酒花的毛蕊期和球果生长期有2个发生高峰。本文以啤酒花越冬期,营养生长期、生殖生长期害螨和天敌发生特点,提出了不同的防治方法和技术关键。更多还原

【Abstract】 Strawberry spider mite(SSM)is a serious pest of hops in Xin Jiang.The biology and integrated pest control of the animal in hops in the Xin Jiang region have been studied in 1991.Having the character of wide opectrum of the hosts,SSM injures not only Lhe leaves,buL also Lhe flowers and Lhe co- nes.(In early Spring,adults of SSM move from the winter habitat in the soil onto the weeds,such as Lhe Concotoutus arvensis L.,In early June SSM moves from the weeds onto the hops and feed on the hops leaves.)There are two pe- aks of dynamics of SSM which occurred in hair-flower stage(From early July to mid-July)and the cones stage of the hops(From Mid-August to the end of August)during the whole seasons of hops,The relevance of the pest-host into- eractions,and the integrated control programme were discussed on the basis of ur findings.更多还原
