中文摘要：在郑州通过室外埋卵观察，草履蚧Drosicha corpulenta Kuwana从1月初开始孵化，孵化后在土里等到2月初开始出土，此时日最高气温在6～8℃之间。若虫出土期约30 d，2月中下旬为出土高峰期。经设置14，18，22，26和30℃ 5个温度梯度观察，草履蚧1龄若虫发育起点温度为7.9℃，有效积温为203.8日·度。利用树干绑缚杀虫药带防治效果达到98%以上。
英文摘要：Bionomics of first instar of the giant mealy bug, Drosicha corpulenta, and its control. By observing in the field，the giant mealy bug hatched from the beginning of January Zhengzhou. But they stayed in the soil until the beginning of February, when the highest temperature reached about 6～8℃. The peak of the larvae climbing up the tree is from the middle to the end of February. Being bred at 14, 18, 22, 26, and 30℃, the development threshold temperature for first instar is 7.9℃, and the effective accumulated temperature is 203.8 degree-day. Treated with pesticide strip on the trunk，the number of larvae can be reduced over 98% on the tree.
