| 摘 要： | 杏球坚蚧在张家口地区1年发生1代,以2龄若虫越冬,翌年3月中旬开始活动。雌成虫于4月下旬至5月上旬产卵,5月中旬卵孵化,9月下旬进入越冬期。药剂防治以3月中旬越冬若虫出蛰期和5月下旬初龄若虫盛期为防治适期;在防治适期可喷施40%速扑杀乳油1 000倍液和2.5%功夫水乳剂2 000倍液和防治效果可达86.63%~97.15%.

| Abstract: | Objective:Sphaerolecanium prunastri occurs 1 generation each year and the second instar nymphs is of its overwintering and oversummering generation in Zhangjiakou of Hebei Province.It comes into playing in the middle days of next March.The female adults oviposit from the last ten days of April to the first ten days of May and hatch in mid-May.In the last days of September,it begins overmintering.The best period for chemical control is the middle ten days of March(over hibernation) and the last ten days of May(property stage of nymph).In the optimum control stage,the controlling result can reach 86.63~97.15% by plying Supracide 40% EC(1 000X) or Lambda-cyhalothrin 2.5% EW(2 000X),etc. |
