摘要: 目的 研究淡色库蚊幼虫期营养对成蚊体型、生理状态及摄糖行为的影响。方法 于2014年8月在杭州市某居民小区蓄水池内采集淡色库蚊幼虫,以3种食物量进行饲养,对新羽化的成蚊翅长、体质量及糖类、脂类和蛋白质含量进行测定;以葡萄糖溶液作为糖餐喂食新羽化的成蚊,对趋糖比例的时间变化进行测定。结果 不同营养条件下新羽化的雌雄成蚊翅长分别为4.26~3.57和3.53~2.99 mm,雌雄蚊体质量分别为3.16~1.53和1.95~1.12 mg,差异有统计学意义(P<0.05)。雌雄蚊糖类含量分别为41.76~19.90和39.62~14.66 μg/只,脂类含量分别为48.23~17.48和52.36~9.42 μg/只,蛋白质含量分别为68.07~34.23和59.82~24.85 μg/只,雌雄蚊能量储备分别为3.70~1.58和3.68~1.03 J/只。幼虫期食物充足的新羽化成蚊摄糖比例最高,雌雄蚊分别为70.80%和53.30%,且自羽化后成蚊摄糖比例不断升高。结论 不同营养条件下淡色库蚊新羽化的雌雄成蚊翅长、体质量、糖类、脂质及蛋白质含量不同;淡色库蚊幼虫期食物丰富度可显著影响成蚊的体型、生理状态和摄糖趋性。

Abstract: Objective To investigate the effect of larval nutritional regimes on the body size, physiological condition and sugar feeding behavior of Culex pipiens pallens adults. Methods Culex pipiens pallens larvae, which were collected from water pools in the urban residential areas of Hangzhou city in August, 2014, were reared with three diet regimes, and the wing length and body weight of newly emerged adults, as well as the contents of glycogen, lipid and protein, were determined. Newly emerged adults from different larval nutritional regimes were provided with glucose solution as sugar source, and the temporal change of proportions of sugar-fed mosquitoes was determined. Results The wing length of newly emerged female and male mosquitoes from different groups was 4.26-3.57 mm and 3.53-2.99 mm respectively, their body weight was 3.16-1.53 mg and 1.95-1.12 mg respectively, the differences were statistically significant between these larval nutritional regimes (P<0.05). The content of sugar from individual newly emerged female and male mosquitoes was 41.76-19.90 μg and 39.62-14.66 μg respectively; the content of lipid was 48.23-17.48 μg and 52.36-9.42 μg respectively; the content of protein was 59.82-24.85 μg and 68.07-34.23 μg respectively; the energy reserves of newly emerged female and male Cx. pipiens pallens were 3.70-1.58 J and 3.68-1.03 J, respectively. The proportion of sugar-fed newly emerged mosquitoes from rich larval nutritional regimes was highest among the groups, which was 70.80% for females and 53.30% for males, and the values continuously increased since adults emerged. Conclusion The wing length and body weight, as well as the content of sugar, lipid and protein, were different in newly emerged female and male Cx. pipiens pallens from different nutritional regimes; the abundance of larval food could significantly affect the body size, physiological condition of Cx. pipiens pallens adults and their tendency to sugar sources.
