| 中文摘要: |
| 用DT-311N频闪仪对棉铃虫、黏虫和小地老虎的振翅频率进行测定，发现各种昆虫之间振翅频率存在显著差异。日龄和温度对三种昆虫的振翅频率均有显著影响。振翅频率随日龄的增长存在抛物线增长，振翅频率产卵前后（7日龄左右）达到最大，随后逐渐降低。三种昆虫的振翅频率都随温度的变化而变化。在12~32 ℃范围内，棉铃虫振翅频率在28 ℃和32 ℃时显著高于其他温度，而黏虫和小地老虎振翅频率分别在28 ℃和24 ℃时达到最大值。 |
| 英文摘要: |
| The wingbeat frequency of oriental armyworm Mythimna separata, cotton bollworm Helicoverpa armigera and black cutworm Agrotis ypsilon were measured using DT 311N stroboscope in the laboratory. There was significant difference in wingbeat frequency between different species. Both age and temperature significantly influenced the wingbeat frequency in the three species. Wingbeat frequency increased parabolically as insects aged, with the maximum recorded on the 7th day after emergence, and after this it decreased. The wingbeat frequency varied between different temperatures ranging between 12 ℃ and 32 ℃. It was higher at 28 ℃ and 32 ℃ than at other temperatures in H.armigera, but reached maximum at 28 ℃ in M.separata and at 24 ℃ in A.ypsilon. |
