Abstract: Chemical control of Ceroplastes rubens damaged Cedrus deodara was made in Jinhua urban district of Zhejiang Province during 1996 ~ 1998 .The results revealed that there was a great deal of difference in control effectiveness after spraying different insecticides and different densities .Control of Ceroplastes rubens could be made at the initial nymph stage by spraying tree crowns with 437 mgL-1 and 267 mgL-1 of omethoate 40 EC or 437mgL-1 and 267 mgL-1 of omethoate-buprosezin 35EC , resulting in more than 80 % of the nymph being killed .
