| Abstract: | Eucryptorrhnchus brandti (Harold) and E.chinensis (Olivier) have attacked Ailanthus altissima Swingle so seriously that caused wither and death of the trees since 1990. E.brandti has one generation a year and overwinters as larva and adult in Lanzhou.The control result showed that the measures such as applying insecticides and artificial catching were effective,the populationt density has reduced from 6.045 to 0.467 per plant. |
