雄性和雌性蚊子都消耗代谢能量所需的富含糖的花蜜,但只有雌性蚊子消耗卵子发育所需的富含蛋白质的血粉。每餐的大小对行为和繁殖有后续影响;因此,精确的定量是蚊子摄食行为研究的一个重要方面。该方案描述了一种高通量的终点测定,以量化个体蚊子摄入的膳食体积。向膳食中添加荧光染料允许膳食大小量化。在96孔板中均质化已经喂食该膳食的个体蚊子,并且用读板器测量荧光水平。该方案还可以适用于确定膳食组成的改变是否影响摄入的膳食体积,蚊子品系或基因型是否决定消耗,或者膳食是否来自多个来源。
Both male and female mosquitoes consume sugar-rich nectar meals required for metabolic energy, but only females consume protein-rich blood meals, which are required for egg development. The size of each meal consumed has subsequent effects on behavior and reproduction; therefore, precise quantification is an important aspect of mosquito feeding behavior studies. This protocol describes a high-throughput, end-point assay to quantify meal volumes ingested by individual mosquitoes. The addition of a fluorescent dye to the meal allows for meal size quantification. Individual mosquitoes that have been fed this meal are homogenized in 96-well plates, and the fluorescence levels are measured with a plate reader. This protocol can also be adapted to determine if alteration of meal composition affects the ingested meal volume, if mosquito strain or genotype dictates consumption, or if meals are derived from multiple sources.
