This study was conducted to better understand the effect of different sucrose concentrations on Aedes albopictus fecundity, biting behavior and survival. Laboratory strain Ae. albopictus females were raised at four different sucrose concentrations (10%, 30%, 50%, and 70%) and their fecundity, host biting on and survival rates were determined. Mosquitoes fed on high (50% or 70%) showed higher mean fecundity rate compared to those on low (10% or 30%) sucrose concentration, and had higher daily biting rate. On the other hand, mosquitoes fed on the low (10% or 30%) sucrose concentrations recorded higher survival rate. These results suggest female mosquitoes deficient in nutrient intake during sugar feeding may regain nutrients needed during blood feeding, whereas those fed on high sucrose concentration have high fecundity due to high biting rate but have low survivability due to low sucrose intake during sugar feeding. Thus, Ae. albopictus females have a capability to regulate their metabolic needs based on sugar nutrient availability.
本研究旨在更好地了解不同蔗糖浓度对白纹伊蚊繁殖力、叮咬行为和生存的影响。实验室品系的白纹伊蚊雌性在四种不同蔗糖浓度（10%、30%、50%和70%）下饲养，并测定其繁殖力、宿主叮咬率和生存率。与喂食低蔗糖浓度（10%或30%）的蚊子相比，喂食高蔗糖浓度（50%或70%）的蚊子平均繁殖率更高，每日叮咬率也更高。另一方面，喂食低蔗糖浓度（10%或30%）的蚊子生存率更高。这些结果表明，在吸食糖类时营养摄入不足的雌蚊可能在吸食血液时重新获得所需营养，而那些喂食高蔗糖浓度的蚊子由于叮咬率高而繁殖力高，但由于在吸食糖类时蔗糖摄入量低而生存能力低。因此，白纹伊蚊雌性有能力根据糖类营养的可获得性来调节其代谢需求。
