摘 要：
为明确柠条绿虎天牛Chlorophorus caragana Xie&Wang幼虫的龄期,以便进行预测预报及采取防治措施。通过林间采集柠条绿虎天牛幼虫,并根据前胸背板宽、触角孔间距和体长3项形态指标的频次分布结果初步划分龄期,然后利用戴氏生长法则和线性回归进行验证。结果表明:柠条绿虎天牛幼虫可分为7龄,触角孔间距和前胸背板宽符合Dyar法则和Crosby法则并呈现明显的线性回归关系,可作为龄期划分的重要指标。体长不符合Crosby法则,不宜用于区分龄期。

摘 要：
To determine the instars of Chlorophorus caragana Xie &Wang(Coleoptera:Cerambycidae)larvae for forecasting and scientific management of this pest,C.caraganalarvae were collected in the field,and three body parameters(pronotum width,antennal ring spacing,body length)were measured.The parameters were analyzed by frequency distribution and then tested by the Crosby growth law and linear regression.The results showed that the larva of C.caragana had seven instars.The pronotum width and antennal ring spacing conformed to the Dyar and Crosby rules,with obvious linear relations,making them important criteria for identifying larval instars.The body length did not conformed to the Crosby rule,and should not be used for defining larval instars.
