摘要
兰矩瘤蛎蚧 (EucornuaspismachiliMaskell)是上海地区危害香樟 (Cinnamomumcamphora) 的新害虫 ,在绿带内对香樟生长造成较大威胁。该虫在上海地区 1年发生 3代 ,大多以受精的雌成虫越冬 ,少量以孕卵雌成虫、产卵雌成虫和若虫越冬。第 1代若虫 3月下旬始见 ,孵化高峰为 4月下旬至 5月上旬 ;第 2代若虫孵化高峰期为 7月下旬至 8月上旬 ;第 3代若虫孵化高峰期为 10月上旬至 10月中旬。经试验 ,在第 1代若虫孵化高峰时用 10 %吡虫啉 (Imidacloprid)WP2 0 0 0倍液、花保EW 10 0倍液喷防、树虫一针净 (30 %敌畏·氧乐 )EC原液滴注 ,防效达 88.14 %～ 96 .75 % ;若虫固定后可用 95 %蚧螨灵 (Petroleumoil) 10 0倍液喷防 ,2 9d后校正防效可达 93.5 7%。
Eucornuaspis machili is a new pest attacking Cinnamomum camphora in Shanghai area. It seriously imperils Cinnamomum camphora growth in the greenbelt. It has three generations in one year in Shanghai. Most of them when hibernating are fertilized female imagoes and only a few are gestated female imagoes,egg-laying female imagoes and nymphs. First generation nymphs occur in the last 10 days ,and the peak hatching stage is between the last ten days of April and the first ten days of May. The peak hatching stage of the second generation nymphs is from the last ten days of July to the first ten days of August and that of the third ones is from the first ten days of October to the next ten days .The control test showed that the control efficiency reached 88.14%～96.75% by using 10% imidacloprid WP or Hua Bao or Shu Chong Yi Zhen Jing EC at the peak hatching stage of the first generation nymphs;and after the nymphs fixed,the control efficiency after 29 days could reach 93.57% by using 95% Jie Man Ling Peproleum oil.
