| 中文摘要: |
| 榴绒蚧（ Eriococcus lagerostroemiae Kuwana ）在攀西地区1年发生3～4代，以4代为主，有明显的世代重叠。大多以末龄若虫越冬，少数以卵越冬。树龄8～12年的石榴树被害严重，多以若虫、雌成虫群集于树干、枝条、果柄等部位为害，一般不为害叶片或果实。该虫在攀西地区的主要捕食性天敌是红点唇瓢虫（Chilocorus kuwanae Silvestri），红点唇瓢虫对榴绒蚧种群数量的增加具有十分显著的抑制作用。 |
| 英文摘要: |
| Eriococcus lagerostroemiae Kuwana occurs 3~4 generations during a year in the Panzhihua-Xichang area, has an obvious mixture of generations. Majority survive the winter as the full-grown Nymph , minority as egg. 8~12 years old Punica granatum L is damaged obviously. Stem, branch, carpophore are obviously damaged by the gathering of Nymph and Female adults on them , Leaves and fruit are not damaged generally. Its main predator in the Panzhihua-Xichang area is Chilocorus kuwanae Silvestri, Chilocorus kuwanae Silvestri has an obvious inhibitory effect on the growth of population quantity of Eriococcus lagerostroemiae Kuwana. |
