| 摘 要： | 西藏飞蝗Locusta migratoria tibetensis Chen是青藏高原的重要农牧业害虫。对该虫各发育阶段的过冷却点和结冰点的测定表明,西藏飞蝗卵的过冷却点和结冰点为最低,分别为-22.02℃、-16.36℃,4龄蝻的过冷却点和结冰点最高,分别是-6.46℃和-5.05℃,西藏飞蝗在甘孜以卵越冬。 |
| 关 键 词： | 西藏飞蝗 过冷却点 结冰点 耐寒性 |

| Abstract: | Locusta migratoria tibetensis Chen is an important pest of agriculture and animal husbandry in Qinghai-Tibet Plateau.The super-cooling point and freezing point of the L.migratoria tibetensis in each developmental stage were tested.The results indicated that the super-cooling point and freezing point of egg were the lowest among all stages,which was-22.02℃ and-16.36℃,respectively.The super-cooling point and freezing point of 4th instar nymph were the highest among all nymph stages,which were-6.46℃ and-5.05℃ respectively.So L.migratoria tibetensis overwinters in egg in Ganzi State,Sichuan. |
| Keywords: | Locusta migratoria tibetensis super-cooling point freezing point cold-hardiness |
