摘　　要：三角帆蚌是国内也是全世界最优良的淡水育珠蚌，所产珍珠圆润饱满，最受人喜爱。三角帆蚌的幼蚌，最易受摇蚊幼虫的危害，造成蚌壳穿孔而死亡。介绍两种摇蚊幼虫在育珠池塘中，危害幼蚌严重时，可使１／３的幼蚌死亡，损失较大。采取改进幼蚌吊养方式，及时清洗网袋和幼蚌，施生石灰和敌百虫，能有效地防治摇蚊幼虫。Hyriopsis cumingii (Lea ) is the best fresh water pearl-producing shellfish in China and theworld. Its pearls are round and bright,smooth-skinned and plump,and people like them best.But its 10～13 months young shellfish with the body length of 4～8cm, are easily damaged bythe larvae of Chironomidae which cause their shell holed and the young shellfish die. This pa-per introduces 2 species of chironomidae,their larvae grow in the pond in which fresh waterpearl-producing shellfish are reaved.Their heavy damage would make 1/3 of the shellfish dieand causes heavy losses to the pearl rearers. The authors of this paper adopt a new hangingmethod, wash nets and young shellfish on time,and spray quick lime and dipterex,which cancontrol the larvae of Chironomidae.
