摘　　要：油茶（Camellia oleifera Abel.）又叫茶子树,是我国特有的油料树种,与油橄榄（Olea europaea L.）、椰子（Cocos nucifera L.）、油棕（Elaeis guineensis Jacq.）并称为世界四大木本油料植物。山茶油不饱和脂肪酸含量达90%以上,被誉为“东方橄榄油”,Casmara patrona is one of the main borer pests damaging Camellia oleifera in China. Few reports about this insect were published. The life history, biological characteristics and natural enemies of C. patrona were inves- tigated through field survey and laboratory observation in this study. The results showed that C. patrona had one generation in one year or two years, and overwintered as 3rd - 5th instar larva in Zhejiang Province. About 88 per- cent of larvae began to pupate in early May, and the rest kept feeding till the next year. The adults could be ob- served from early June to early July, and the peak of emergence occurred in late June. The adults began to oviposit in late June and terminated in early July. The eggs started hatching in early July, and then the larvae bored into the branch to feed. The entrance holes of the larvae distributed predominately in the middle of the eastern and southern part of C. oleifera tree. The larva had five instars, and there were 10 -50 days when the larva did not feed between consecutive instars.
