对截形叶螨在树干上的越冬分布、出蛰后的转移规律、耐饥饿能力、爬行速度、寄主杂草等进行为期2 a的研究。截形叶螨在枣树主干树皮裂缝、主枝和树干基部的土壤缝隙中均能越冬,其中距地面60 cm左右的主干是主要越冬场所,越冬数量占总虫数的70%,主枝次之。从树干不同方位上的越冬情况来看,主干南面越冬数量最多。出蛰后的成螨沿树干转移取食。其耐饥饿时间为24~104 h、死亡高峰期间为56~80 h。这为冬季和早春用树干捆草圈诱杀、刮老树皮、喷洒农药等措施来降低越冬虫口密度和树干涂抹毒环诱杀、阻止转移以及清除灰绿藜等措施来控制截形叶螨提供了理论依据。
The 2-month-old study on the winter distribution of Truncated Tetranychus urticae on tree trunks, the transfer rule after stung, hunger resistance, crawling speed and host weeds were conducted. Tetranychus urticae could winters in the cracks of the trunk bark, the main branch and the crevice of the trunk at the trunk of the jujube tree, of which the trunk about 60 cm from the ground was the main wintering place, the number of overwintering accounted for 70% of the total number of insects, Second. According to the overwintering situation in different directions of the trunk, the number of overwintering in the south of the trunk is the largest. After the sting mites migrate along the trunk feeding. Its resistance to hunger is 24 ~ 104 h, 56 ~ 80 h during the peak of death. This provides control of truncated spider mites in winter and early spring with trunks of bark mowing and trapping, shaving of old barks, spraying of pesticides and the like to reduce overwintering insect population density and trunks to poison the loop traps, prevent transfer, and remove glabridin Theoretical basis.
