| 中文摘要: |
| 南亚实蝇Bactrocera tau (Walker)是一种重要的入侵性农业害虫?主要分布在我国云南?广东?四川和河南等地, 南亚实蝇的为害严重降低了蔬菜和水果的品质?短时极端温度是影响南亚实蝇种群的重要因子?为了明确短时高低温对南亚实蝇的影响, 通过选择12 h的短时低温(-4?0?4?8℃)及12 h的短时高温(34?38?42?46℃), 在实验室条件下系统研究短时高低温胁迫对南亚实蝇种群生长发育和繁殖的影响?结果表明, 在短时高/低温处理后, 南亚实蝇各虫态的存活率随着处理温度的升高/降低逐渐下降; 随着处理短时高/低温的升高/降低, 南亚实蝇发育历期?产卵前期和后代性比逐渐增加; 随着短时高温处理温度的升高, 雌雄成虫的寿命先延长后缩短, 单雌产卵量逐渐减少; 随着短时低温处理温度的降低, 雌雄成虫的寿命逐渐缩短, 单雌产卵量先增加后减少?短时高温和短时低温均对南亚实蝇的生长发育和繁殖有着不利的影响, 但一定的低温(8℃)处理后对雌成虫繁殖力有一定的促进作用? |
| 英文摘要: |
| Bactrocera tau (Walker) is an important agricultural invasive insect pest. It is mainly distributed in Yunnan, Guangdong, Sichuan and Henan provinces of China. The serious damage of B.tau can reduce the quality of vegetables and fruits. The short-term extreme temperature is an important factor affecting the population of B.tau. In order to determine the effect of short-term high and low temperature on the growth, development and reproduction of B.tau, the effects of short-term low temperature (-4, 0, 4, 8℃) for 12 hours and short-term high temperature (34, 38, 42, 46℃) for 12 hours were studied under laboratory conditions. The results showed that the survival rates of all stages gradually decreased with the increase and decrease of the treatment temperature after short-term high and low temperature treatments. The developmental period, preoviposition period, single female oviposition, longevity and the sex ratio of offspring were significantly affected by the treatments. The developmental period, sex ratio and preoviposition period gradually increased with increasing/decreasing temperature; the longevity of male and female adults initially increased and then decreased, while the single female oviposition gradually decreased with increasing treatment temperature. Meanwhile, their longevity gradually decreased and the single female oviposition increased and then decreased with decreasing treatment temperature. Overall, the short-term high and low temperature had negative effects on the growth, development and reproduction of B.tau. This could slightly promote the reproduction of females in a certain range of short-term low temperature (8℃). |
