草莓红蜘蛛学名朱砂叶螨(Tetranychus cinnabarinus Boisduval),是草莓收果期的重要害虫。草莓生长中、后期,经常遭受红蜘蛛的暴发危害,被害植株矮化早衰,叶片红褐色干枯;开花期受害,果实缩小,畸形果增多,严重影响草莓鲜果的产量。尤以塑料大棚保温栽培的受害最重,减产达30～40％。1988年以来,我们对草莓红蜘蛛的发生危害,进行了调查观察和防治试验,基本明确了草莓红蜘蛛的危害规律和防治对策,为大面积开展防治工作提供了依据。 Strawberry red spider scientific name Tetranychus cinnabarinus Boisduval, strawberry is an important pest of fruit. Strawberry growth in the late, often suffering from the outbreak of red spider damage, premature dwarf plant damage, leaves reddish-brown dry; flowering victims, fruit shrinkage, abnormal fruit increased, seriously affecting the yield of strawberry fruit. Especially plastic greenhouse cultivation of the most affected heat, yield up to 30 to 40%. Since 1988, we have done harm to strawberry spider mites, conducted investigation and prevention and control tests, and basically defined the damage rules and control strategies of strawberry spider mites, which provided the basis for prevention and control work in a large area.
