在四种按蚊中，均发现了一种新的按蚊。albimanus、白纹隐翅虫An. gambiae、冈比亚角隐翅虫An. stephensi和An. quadramaculatus说，总蛋白质，脂质和碳水化合物存在于羽化，后喂食蔗糖，和极端饥饿后进行了定量研究的影响teneral和最大储备随后的繁殖力和判断储备动员的程度和生存所需的最小不可减少的量。所有的参数都回归到身体的大小，作为翼长的立方值。总储量与个体大小成等比例，明显低于以往报道的埃及伊蚊（L.）并且在储备和体型方面具有性二态性，雄性的储备和体型都略有减少。平均而言，高达70%的teneral女性脂质和高达50%的teneral蛋白质可以动员在营养胁迫。相反，获得蔗糖几天导致显着的糖原生成（高达509%）和脂肪生成（高达teneral值的450%），这取决于物种。在绝对值上，脂肪生成优于糖原生成。在热量的基础上，高达30%的血粉蛋白质用于合成蛋黄蛋白和脂质，另外15%作为卵巢外的母体蛋白质和脂质储存，也许可以补偿有限的总储备。一个完整的氮预算显示，在一个给定的类的身体大小，大约80%的血粉蛋白分解代谢和排泄的三个主要途径的尿酸，尿素，和ammonotely。粪便样品中血红素的定量允许血液摄入量的化学计量测定。生态生理方面的幼虫喂养，teneral储备，血粉利用，以及可能的行为适应这些生理限制进行了讨论，并与以前的数据culicine蚊子，强调这些类群之间的概括无效。
In four Anopheles species, An. albimanus, An. gambiae, An. stephensi, and An. quadrimaculatus Say, total protein, lipid, and carbohydrate present at eclosion, after feeding on sucrose, and after extreme starvation were quantified to study the effect of teneral and maximal reserves on subsequent fecundity and to judge the extent of reserve mobilization and the minimal irreducible amounts required for survival. All parameters were regressed on body size, presented as the cubic value of wing length. Teneral reserves were isometric with body size, were considerably lower than previously reported for Aedes aegypti (L.) and were sexually dimorphic with respect to reserves and body size, all being slightly reduced in males. On the average, up to 70% of the teneral female lipids and up to 50% of their teneral protein could be mobilized during nutritive stress. Conversely, access to sucrose for a few days led to a pronounced glycogenesis (up to 509%) and lipogenesis (up to 450% of the teneral values), depending on the species. In absolute terms, lipogenesis prevailed over glycogenesis. On a caloric basis, up to 30% of the blood meal protein was utilized for synthesis of yolk protein and lipid, and another 15% was deposited as an extra-ovarian, maternal protein and lipid store, perhaps compensating for the limited teneral reserves. A complete nitrogen budget revealed that in a given class of body size, roughly 80% of the blood meal protein was catabolized and excreted through the three major pathways of uricotely, ureotely, and ammonotely. Quantification of the hematin in fecal samples allowed a stoichiometrical determination of the amount of blood ingested. Eco-physiological aspects of larval feeding, teneral reserves, blood meal utilization, and possible behavioral adaptations to these physiological constraints are discussed and compared with previous data on culicine mosquitoes, stressing the invalidity of generalizations among these taxa.
