| description | Objective: To understand the efficacy of ovitrap surveillance and its implementation on
monitoring reflection upon case occurrence in relation to climate variables.
Methods: We used routinely setup ovitrap surveillance to monitor the mosquito populations
in previous outbreak areas. Ovitraps were installed weekly at three localities that experienced
high number of dengue cases (Flat Hamna, Kampung Sungai Gelugor and Kampung Tanjung
Tokong) from January 2010 to February 2011. Ovitraps and paddles were brought back to
the laboratory and all of the water contents were poured into an enamel pan. Aged tap water
was added into the enamel pan and eggs were allowed to hatch. The hatching larvae were
counted after 3 days. The hatched larvae were identified at the 3rd instar larval stage. The
ovitrap indices and mean number of larvae were analyzed using student t-test and One-way
ANOVA. Spearmen’s rank correlation coefficient was used to determine the relation between
meteorology variables and dengue fever cases.
Results: Aedes albopictus was found as dominant species followed by Aedes aegypti recorded
in all three study areas. Aedes aegypti preferred to breed outdoor with larvae collection, which
was higher than indoor (72.37%). There was a positive correlation between the ovitrap index
with the rainfall and humidity except in Kampung Tanjung Tokong. Our result also showed
negative correlation between temperature and ovitrap index in all localities. |
