通过近2a观察表明,徐州地区烟粉虱在田间消长大致分4个阶段,成虫有4个主要迁移期;其喜干热、耐高湿的生活习性、冬季保护地栽培面积的扩大、外来虫源的传入及防治不力是烟粉虱种群数量累积并引起暴发的主要原因;主要寄主有9科20余种栽培作物;寄主植株上虫量垂直分布:棉花上部>中部>下部,温室蔬菜一般中、下部>上部。可采取严格检疫、清洁田园、轮作换茬、黄板诱杀、覆盖防虫网、保护和利用天敌、药剂防治等措施进行治理。
Nearly 2 a observations showed that the population of whitefly Bemisia tabaci in the Xuzhou area was roughly divided into four stages and the adults had four main migration stages. The hi-hat heat and high humidity tolerant habits, the expansion of cultivation area in winter protected areas, The introduction and control of the source is the main reason for the population accumulation and the outbreak of Bemisia tabaci. The main host has more than 20 cultivated crops in 9 families. The vertical distribution of insect population on the host plants is: cotton upper part> middle part> lower part, greenhouse vegetables Middle, lower> upper part. Can take strict quarantine, cleaning the pastoral, rotation cropping, yellow board trapping, covering insecticidal network, protection and use of natural enemies, pharmaceutical control and other measures for governance.
