TITLE:

SUMMARY:

Given the importance of the Aedes aegypti as arboviroses vector, understanding the impact
of abiotic factors, such as population density in the larval rearing s, during larval development,
is fundamental to improve control methods. The aims of this work were to analyze the effects of
population density on the triacylglycerol (TAG) reserves, fecundity and the size of mosquitos.
To evaluate the influence of density on the amount of triacylglycerol in the different stages of
development of A. aegypti, the larvae were reared in the following densities 0.04, 0.32 and 0.8
larvae / mL, represented by D1, D2 and D3, respectively. It was observed that different larval
rearing affected the amount of triacylglycerol on the different development stages of this insect.
The group reared in a high population density (D3) presented greater storage of triacylglycerol,
except when analyzing the amount of triacylglycerol μg/protein of fat body in blood-fed
females. In addition, it was possible to observe a higher resistance to fasting, higher amount of
laid eggs. Insects reared on D2 and D3 were larger than D1. This study provided interesting data
for future investigations as to how densitiy of larval rearing affect the lipid metabolism
concerning to synthesis and mobilization of triacylglycerol store in A. aegypti and how does it
influences it size and the reproduction.
