Study on the effect of red lime solution on the oviposition of Aedes aegypti L.

ABSTRACT

The study on the effect of red lime solution on the oviposition of Aedes aegypti L. was conducted using 4-day old, blood-fed Aedes aegypti L. females. Twenty mosquitoes were kept in each of 10 rearing cages. Four cups containing filter papers along with three concentrations (w/v) of red lime solution, namely, 0.06%, 0.6%, and 6.0%, and pure water, as control, were provided in each rearing cage for oviposition sites. The result revealed that Aedes aegypti L. females were able to lay eggs on all filter papers. A total of 1340, 372, 87 and 2881 eggs were laid in the cups containing 0.06%, 0.6%, 6.0% red lime solution and pure water, respectively. There was no significant difference in number of eggs between the concentration of 0.6% and 6.0% (P\>0.01). On the other hand, there were highly significant differences among other concentrations of red lime solution ( P
