Abstract:
Laboratory colonised mosquitoes are usually maintained on vitamin B complex
fortified sucrose solution, however only few studies were conducted to evaluate the effects
of such practice. This study aimed to determine the effects of different concentrations of
sucrose solution fortified with and without 1% vitamin B complex on the longevity and
reproductive potential of adult female of a local strain of Culex quinquefasciatus Say. Two
arms of studies were carried out separately and each arm was triplicated. In one arm,
concentrations of sucrose solution at 0%, 1%, 3%, 5% and 10% fortified with 1% Vitamin B
complex were fed to the mosquitoes, while in the other arm, similar sucrose concentrations
were used but without 1% vitamin B complex. Adult Cx. quinquefasciatus maintained on 5%
sucrose solution fortified with 1% vitamin B complex exhibited significant extended vitality
and longevity in stimulating ovarian development, compared with other vitamin fortified
sucrose concentrations (p<0.05). The vitality and longevity of F0 and F1 males were 76.67±2.19
days and 57.67±8.19 days respectively. The F0 females survived the longest duration of
107.67±5.61 days and the F1 females survived 90.67±12.47 days with higher number of eggs
laid, i.e. 1427.67±62.89 eggs at a higher hatchability rate of 57.05±8.39% or 814.49 eggs
hatched. Thus, 5% sucrose solution fortified with 1% Vitamin B complex should be used to
produce colonies of homogenous mosquitoes as this exerts positive biological effects on
laboratory-bred Cx. quinquefasciatus.
