【目的】对前人的眉斑并脊天牛（Glenea cantor Fabricius）幼虫饲养方法进行改进,以获得大量虫源,为系统研究该虫提供虫源保障。【方法】采用50 m L平底生物离心管,内置小木段,将眉斑并脊天牛幼虫转移至离心管内的小木段上,在温度（25&...【目的】对前人的眉斑并脊天牛（Glenea cantor Fabricius）幼虫饲养方法进行改进,以获得大量虫源,为系统研究该虫提供虫源保障。【方法】采用50 m L平底生物离心管,内置小木段,将眉斑并脊天牛幼虫转移至离心管内的小木段上,在温度（25±1）℃、相对湿度（75±5）%、光周期14L∶10D的条件下饲养,观察幼虫羽化情况,将羽化的成虫分别称重并统计性比、幼虫存活率和羽化率。【结果】所饲养的幼虫总存活率达（88.9±1.96）%,平均羽化率达（96.49±1.06）%,雌、雄成虫平均体重分别达0.2174±0.0011 g和0.1086±0.0052 g,成虫体重与自然种群无显著差异（P〉0.05）;幼虫正常发育对饲料量有一定要求,每头幼虫的饵料平均需要量为26.01-34.00 g,低于26.00 g的饲料量饲养出来的成虫体重明显偏小,与自然种群差异显著（P〈0.05）。【结论】50 m L平底生物离心管法是一种一次性接虫、不需更换饲料、耗材少的饲养方法,可用于眉斑并脊天牛幼虫的定量饲养。展开更多
