| description | Dengue disease in Malaysia is increasing at an alarming rate. The district of Petaling,
Selangor contribute more than 50 percent of the total number of Dengue cases in
Malaysia. This study was carried out to show the use of Insecticide in Aedes mosquito
control is ineffective because they also kill the mosquito predators which deter the
breeding of aedes mosquito. It was done by inspecting 85 existing potential breeding
points of aedes larvae distributed in 15 localities at hotspots area (where the incidences
of dengue outbreak never stop for more than 30 days) with the presence of at least one
mosquito predators. Frequency of Aedes larvae breeding, the incidences of dengue in
relation to the presence of mosquito predator and the impact of insecticide used in the
ecosystem were used to determine the objective. The mosquito predators identified
was Gambushia fish, tadpoles, dragonfly nymph, frog and dragonfly. To determine
the frequency of mosquito larvae in relation to the presence of predators, inspection
was done at 85 existing potential breeding receptacles at 15 localities hotspots daily
for 6 month. The use of data from VEKPRO programme under the Ministry of Health
Malaysia was accessed to evaluate the amount of insecticide used monthly and in
comparative to the number of dengue cases in that area for the year 2014 to 2015.
Result: The frequency of larvae breeding and incidence of dengue cases decrease with
the presence of mosquito predators. The use of insecticide is directly proportional to
the incidence of dengue cases. In conclusion mosquito predators are very vital in
controlling the breeding of aedes mosquito but the use of insecticide exterminated and
damaged the mosquito predators and their habitat. It is recommended that the use of
insecticide in controlling dengue at urban area should be stopped and biological
methods to be introduced in curbing dengue. |
