摘要
云南绵壶蚧在上海地区一年发生１ 代，以受精雌成虫越冬，６ 月中旬产卵，卵期很短，故孵化与产卵几乎同步，孵化期从６ 月中旬到８ 月中旬，高峰在６ 月底到７ 月初。雄成虫羽化始于８ 月下旬，延续到９ 月中旬，高峰在９ 月上旬。防治适期掌握在６ 月底７ 月初若虫孵化高峰期进行化学防治，结合管理修剪，清除虫枝，能收到良好的防治效果。
Phenacobryum indigoferae Borchseninus had one generation yearly and overwintered with female imago after being fertilized in middle June in Shanghai.The egg lasted short period,so incubation was in the same step with oviposition.Incubation period lasted from middle June to middle August and the peak was from late June to early July.Exclusion of imago lasted from late August to middle September,and the peak was early September.The tactics of preventing and controlling phenacobryum indigoferae were the methods of biological and chemical control from late June to early July.
