| 摘 要： | 草履蚧在兰州市1年发生1代,以卵在树干周围的土缝、裂隙、砖石、草堆下越冬。翌年2月中旬孵化,2月下旬出蛰爬行,4月下旬雄虫开始化蛹,5月上旬成虫羽化,5月下旬雌成虫下树产卵。在4月中、下旬,1~2龄若虫危害时,喷洒40%水胺硫磷乳油和2.5%溴氰菊酯乳油,防治效果达86%以上;3月上旬若虫向树上爬行时喷洒8%绿色威雷,防治效果达88%以上。

| Abstract: | Drosicha corpulenta occurs 1 generation in 1 year and lives through the winter by ovum in soil lacuna,crack,in areas under brick,stone and hay around trees.It hatches in middle February of next year and frees hibernation in late February,male larva begins to pupate in late April and imago's eclosion is in early May,and female imago begins to go down the tree and oviposits in late May.To spray 40% Isocarbophos and 2.5% Deltamethrin in middle and late April when damaged by 1 and half of 2 instar nymphae,the control effect reaches over 86%;to spray 8% Cypermethrin in early March when nymphae crawls towards trees,the control effect is over 88%. |
