油茶象甲Curculio chinensis Chevrolat是油茶的重要果实害虫,为害严重林分果实被害率高达79.3%。本文详细描述了该虫的形态特征;对其生物学特性进行了研究,结果表明该虫在广东省2年发生1代,以老熟幼虫在土内越过第1个冬天、以初羽化的成虫在土内越过第2个冬天,4月上中旬开始出土,5-6月为出土盛期。成虫栖息环境、产卵和油茶果实的生长发育有密切的关系,成虫无交配时多栖息在油茶嫩枝、嫩芽或油茶果实基部的枯萎花絮上,成虫交配盛期多被发现在油茶果实上;油茶果实一般以果皮厚度4.0-6.0 mm着卵量最多,林间每果一般只有1粒卵或1头幼虫。
Curculio chinensis Chevrolat is an important fruit pest of Camellia oleifera, and the rate of damage to the fruit of severely damaged stands is as high as 79.3%. The morphological characteristics of this insect were described in detail. The biological characteristics of this insect were studied. The results showed that this insect occurred one generation in Guangdong Province in the past two years. When the mature larva crossed the first winter in the soil, In the soil over the second winter, April began in the middle of the unearthed, May-June for the unearthed period. Adult habitats, spawning and the growth and development of Camellia oleifera fruit are closely related, adults without copulation and more perch on the tea shoots, buds or the base of the fruit of the withered tea, the adult mating period is found in the fruit of Camellia oleifera ; Camellia fruit generally peel thickness of 4.0-6.0 mm the largest number of eggs, forest usually only one egg or a larva per fruit.
