Abstract
A double layer net (DLN) for sampling of malaria vectors was developed to
compare the sampling efficacy of this method against the conventional
method of human landing catch under semi-field conditions in a screenwalled
corridor using laboratory reared Anopheles dirus KMK strain.
A total of 1300 Anopheles dirus mosquitoes were used for the study and we found that
the collection ratio between the double layer net and human landing catch was 1:2.
The ratio of double layer net catches to those of the human landing catch increased
with decreasing mosquito density. The collection rate was higher for the conventional
method upon the release of the mosquito but gradually decreased with decreasing
density. Mosquito species did not affect the ratio of double layer net to human landing
catches since the trial with Aedes aegypti Aedes albopictus showed a consistent ratio.
Two different colors of outer nets were used (black and white) to compare the sampling
sensitivity between the two different colored materials. The results indicate that there
was no difference in the number of host seeking mosquitoes caught with an equal ratio
of number of catches.
The double layer nets were used to prevent collectors from potentially infectious
mosquito bites and are designed to catch host-seeking mosquitoes only. Although the
sensitivity is half that of conventional method, these traps could be further improved.
