摘　　要：对福建省闽侯桐口国有林场油茶杂交试验林果实的果径、果高、果重、籽重(种仁重)以及果实受害率等进行测定,分析油茶象对油茶果的危害情况。结果表明:在调查的油茶林分中,株受害率为94.7%,平均虫果率为14.7%;健康果平均果径为3.01 cm,显著地大于虫果的2.86 cm;健康果平均果高为3.05 cm,显著地高于虫果的2.84 cm;健康果平均果重为16.8 g.个-1,极显著地大于虫果的果重;健康果籽重为6.2 g.个-1,极显著地大于虫果籽重4.8 g.个-1;结果表明:油茶象的危害严重影响了油茶果的生长和油茶的产量。Fruits of different Curculio chinensis trees in a hybrid forest were collected,then diameter and height of the fruits,weight of fresh fruit and kernel were measured.The result showed infestation rate of C.chinensis trees in the hybrid forest was 94.7%,and the rates of infested fruits was 14.7%,average diameter of healthy fruits was 3.01 cm which was significantly higher than infested fruits（2.86 cm on average）,average height of healthy fruits were 3.05 cm,that was significantly higher than infested fruits（2.84 cm）,those results showed that growth of fruits was significantly affected as the exist larvae of C.chinensis in the fruits.The average weight of per healthy C.oleifera fruit was 16.8 g,which was significantly higher than those with C.chinensis.And average kernel weight of healthy fruits was 6.2 g,that was also significantly higher than infested ones（4.8 g on average）.That meant infestation of C.chinensis would obviously reduce yield of C.oleifera.
