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. |
