摘　　要：通过对福建省毛竹林主要笋期竹笋象种类及危害情况进行调查、鉴定,结果表明:福建省毛竹林竹笋象种类主要有5种:竹笋万纹象(Otidognathus rubriceps Chevrolot)、一字竹笋象(O.davidis(Fairmaire))、小竹笋象(O.nigropictusFab.)、三星竹象虫(Otidognathussp.)、大竹笋象(Cyrtotrachelus longi manus(Fabricius)),其中笋万纹象、三星竹象虫为福建省分布的新记录种。竹笋万纹象和一字竹笋象的分布数量最大,二者占竹笋象的66.7%,也是造成竹笋生长不良、新竹畸形、断梢的主要原因,小竹笋象、三星竹象虫的二次危害加重了毛竹林的受害程度。By investigation and identification,we found that there were five kind of bamboo shoot weevil in Fujian Province： Otidognathus rubriceps Chevrolot,O.davidis（Fairmaire）,O.nigropictus Fab,Otidognathus sp and Cyrtotrachelus longimanus（Fabricius）.And Otidognathus rubriceps Chevrolot and Otidognathus sp were newly found in Fujian.Otidognathus rubriceps Chevrolot and O.davidis（Fairmaire） had the max volume distribution with the proportion of 66.7%,which also did harm to the growth of bamboo shoot,made bamboo shoot deformity and broke the tip of bamboo, and the following invasion of O.nigropictus Fab.and Otidognathus sp made the bamboo seriously injuried.
