| 中文摘要: |
| 双斑长跗萤叶甲是新疆北疆棉花的主要害虫之一, 为探索短时高温对双斑长跗萤叶甲雌虫部分生理指标的影响, 在室内研究了不同高温(33、37、41、45℃)不同时间(0.5、1.5、2.5、6、12 h)处理条件下, 双斑长跗萤叶甲雌虫体内游离氨基酸、可溶性糖及海藻糖的变化规律。结果表明:在相同温度处理下, 随处理时间的延长, 双斑长跗萤叶甲雌虫体内的游离氨基酸含量降低, 可溶性糖和海藻糖含量增加; 在处理时间相同时, 随处理温度的升高, 双斑长跗萤叶甲雌虫体内游离氨基酸含量降低, 可溶性糖含量和海藻糖含量增加。双斑长跗萤叶甲雌虫对45℃高温也有一定的适应性, 这预示着在气候变暖趋势下, 双斑长跗萤叶甲仍将是新疆棉花上重要的害虫之一。 |
| 英文摘要: |
| Monolepta hieroglyphica (Motschulsky) is one of the most serious pests in cotton fields in the north of Xinjiang. This study was aimed to explore the potential physiological and biochemical responses of female adult M. hieroglyphica exposed to high temperature．The variation in free amino acids, total sugar and trehalose in female adult bodies were measured under climate chamber conditions under consistent temperature regimes of 33-45℃ at 4℃ intervals for 0.5 h, 1.5 h, 2.5 h, 6 h and 12 h, respectively．Under the same heat treatment, with the extension of treatment time, the concentration of free amino acids was decreased, while the concentrations of total sugar and trehalose were increased in female adult M. hieroglyphica. For the same treatment time, with rising temperature, the concentration of free amino acids was reduced, but the concentrations of total sugar and trehalose were increased in female adult M. hieroglyphica. M. hieroglyphica even had a certain adaptability to 45℃, and thus is a serious pest to the cotton in Xinjiang under global climate warming. |
