| 摘 要： | 目的 探究不同品种烟草对斜纹夜蛾幼虫生长和营养利用效率的影响。 方法 随机选取了6个烟草品种，分别是野生种的长花烟草和八旦野生烟，地方品种的梁桥晒烟和双管晒烟，选育品种的湘烟5号和中烟100，测试斜纹夜蛾幼虫取食不同品种烟草后的生长发育和营养效应参数。 结果 不同品种烟草对斜纹夜蛾的末龄幼虫干重、发育历期、存活率及各项营养效应参数均有显著影响，其末龄幼虫干重、存活率、相对生长率、相对消耗率、近似消化率、食物利用率的高低依次为选育品种>地方品种>野生种；其发育历期的长短依次为野生种>地方品种>选育品种。 结论 野生种烟草相对地方和选育品种而言对斜纹夜蛾抗性更高。

| Abstract: | This study aims to explore the effects of different tobacco varieties on the growth and food utilization efficiency of spodoptera litura larvae Six tobacco varieties were randomly selected as research objects in this study, including wild varieties of Changhua tobacco and Badan wild tobacco, local varieties of Liangqiao sun cured tobacco and Shuangguan sun cured tobacco, bred varieties of Xiangyan 5 and Zhongyan 100. The growth and nutritional response parameters of S.litura larvae fed on different varieties of tobacco were tested. Different varieties of tobacco all had significant effects on the dry weight, development duration, survival rate and various nutritional effect parameters of the larvae of S.litura. The dry weight, survival rate, relative growth rate, relative consumption rate, approximate digestibility and food utilization rate of the S.litura larvae were in the order of bred varieties > local varieties > wild varieties; the development duration was in the order of wild varieties > local varieties > bred varieties. It can be concluded that wild tobacco has higher resistance to S. litura than local and bred varieties. |
