二斑叶螨是上海地区温室大棚草莓上的重要害虫之一。研究了释放智利小植绥螨防治大棚草莓上二斑叶螨的效果。结果表明,释放智利小植绥螨对草莓二斑叶螨有显著抑制作用,防治效果十分明显。以300头/m2的释放量释放智利小植绥螨14 d后,防效可达99.66%,比5%噻螨酮EC 2 000倍液处理高33.45百分点,释放量为100头/m214 d后的防效也达到了60.24%。且智利小植绥螨具有较大的探索能力,在释放区将害螨捕食完毕后,能迅速扩散到邻近的有害螨的区域继续捕食。
Two-spotted spider mite is one of the most important pests on strawberries in greenhouse in Shanghai. The effects of releasing Chilean phytase mite on the control of Tetranychus urticae in greenhouse were studied. The results showed that the release of Chilean phytase mite on strawberry two-spotted spider mite significant inhibitory effect is very obvious. After releasing the phytosomes of Chilean phytoseid by 300 heads / m2 for 14 days, the control effect reached 99.66%, which was 33.45% higher than that of 5% The control effect has also reached 60.24%. And Chile phyllidae mites have greater exploration ability, in the release area will kill pests mites predation, can quickly spread to neighboring areas of harmful mites continue to prey on.
