| 摘 要： | 根据粘虫Mythimna separata(Walker)具有远距离迁飞能力的特性，在室内条件下，测试其长时间飞行的能源种类及消耗；试验设6h、12h、24h、36h和48h等5种吊飞处理和不 吊飞对照。结果表明，粘虫飞翔后体重显著下降，体重的减少量与吊测时间、实际飞翔时间及距离呈正相关；粘虫飞翔前后体内脂肪含量差异显著，而蛋白质含量则无明显变化；脂肪含量的下降趋势与虫体重下降一致，脂肪消耗量占体重消耗量的60%以上，说明脂肪是粘虫远距离飞行的主要能源物质。随飞翔时间的增加，脂肪消耗的速率有逐渐减缓趋势：飞行每小时每克体重消耗脂肪雌蛾为23.6→8.9mg/(h·g)，雄蛾为11.8→9.2mg/(h.g)；飞行每公里每克体重雌蛾消耗脂肪为4.0→1.7mg/(km·g)，雄蛾为2.2→1.4mg/(km·g)。

| Abstract: | The relationship between utilization of protein and lipid and sustained flight in the moths of Oriental armyworm, Mytkimna separata (Walker) was determined in the laboratory conditions. Under six testing regimes of tethered -flight (0, 6, 12, 24, 36 and 48 hours), the body weight and lipid content in the moths declined significantly as the duration of flight extended while the content of protein was insignificantly affected. The tendency of body weight loss was consistent with the reduction of lipid content, and lipid consisted of 60% of the body weight reduction. It seemed that the rate of lipid reduction was more steady as the flight period extended. The amount of lipid utilized during flight ill females was 8.9-23.6 mg/h (actual flight) and 1.7-4.0 mg/km, while that in males was 7.2- 1 1.8 mg/h and 1.4-2.2 mg/km according to our calculation. Based on the results obtained, it was concluded that the lipid is the major energy source for sustained flight in the moth of M. separata. |
