油茶象(Curculio chinensis Chevrolat)是我国特有木本油料树种——油茶的专性蛀果害虫,常导致大量落果。为明确其基本的生物学特性,2014年在湖南省邵阳县小果油茶林采用震落法捕获油茶象成虫146头,实验室室温下饲养,记录日死亡数,并对其干重、喙长、体长和体宽进行了测量。用独立样本t检验(Independent—samples t test)分析雌雄成虫大小差异性,用线性拟合(Linear fit)分析成虫日死亡数与日最高气温的关系,并用Crosby生长法则对'多峰拟合'分龄结果进行了评价。结果表明:油茶象雌性多于雄性,性比为3.06:1;成虫具2种体色型,即黑色型和褐色型,黑色型为优势种群;成虫最长寿命>100天,7月下旬至8月初...

　　Oil tea weevil (Curculio chinensis) is an important pest attacking the fruits of oil tea camellia (camellia spp.), special oil tree species in China, and often lead to a lot of fruit drop of its host plants.To clarify the basic biological characteristics, a total of 146 weevil adults were captured by shaking-off collection from the farm of Camellia meiocarpa in Shaoyang county of Hunan province in 2014.The adults were fed in laboratory at room temperature.The number of daily dead weevil adults was recorded, and then dry mass, rostrum length...
