RESUMO
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.
