Antibacterial activities in the salivary glands of
female mosquitoes Aedes aegypti were investigated in this
study.
The mean salivary bacteriolytic activity, during a
period of 14-day of female mosquitoes exposed to five
different concentrations of Gram-positive bacteria
Micrococcus lysodeikticus in the sucrose meal, was
detected by a lysoplate method. A logarithmic regression
(R²=0.73) fits the different levels of bacteriolytic
activity during the entire period. As the concentration
of bacteria in the sugar meal increases, the level of
mean salivary bacteriolytic activity increases. A
maximum level of bacteriolytic factor may exist in the
salivary gland when the concentration of M. lysodeikticus
in the sucrose meal exceeds 0.6 g/100 ml. One way
analysis of variance and multiple range analysis for the
different levels of bacteriolytic activity further
validate this finding. The mortality of mosquitoes in
the different treatments was not affected by the
quanti ties of this nonpathogenic bacteria in the sugar
meal.
Salivary bacteriostatic activity of female
mosquitoes against Gram-negative bacteria Escherichia
coli was not detectable in our study, despite positive
preliminary results. / Graduation date: 1993
