为了有效地控制土耳其斯坦叶螨危害,必采取农业的、生物的和化学的综合防治措施.1.发生规律1.1 越冬及出蛰:以交配过的雌成螨.九月上旬开始在棉田或近棉田的水渠边、田埂、土块下及枯枝落叶下越冬;翌年4月中旬到5月中旬出蛰活动;体红色.就近寻找棉田内外的棉苗、苍耳、回旋花、苦(?)菜和苋菜等杂草,取食、活动和产卵等.此期叶螨数量少,繁殖快,是消灭螨源的有利时机.1.2 传播与扩散:可借风力、流水和生物携带等方式传播;扩散迁移靠爬行,如此时高温、干燥、加之控制措施不当,则加速中心株的形成,有利于叶螨的大面积蔓延、串延,因此这时期的重点工作,是及时进行点片挑治,严防成片危害.
In order to effectively control the damage of turpentine spider mites, we must take agricultural, biological and chemical integrated control measures.1 The law of occurrence 1.1 Overwintering and stinging: Female mates have been mated. Beginning in early September in cotton fields or near Cotton fields under the edge of the ditch, under the soil blocks and litter under the winter; the following year from mid-April to mid-May sting activities; body red. Near the cotton fields looking for cotton seedlings, cocklebur, cyclamen, bitter (?) Vegetables and amaranth and other weeds, feeding, activity and spawning, etc. This period of spider mites a small number of fast propagation is an advantageous time to eliminate mite sources .1.2 spread and spread: can be spread by wind, water and biological ways to carry ; Diffusion and migration by crawling, so high temperature, dry, and control measures improper, then accelerate the formation of the center strain is conducive to the spider mites sprawling, string extension, so the focus of this period of work is timely pick and pick , Prevent into pieces harm.
