abstract = {Spatial distribution is one of the key elements in disease
epidemiology and implementation of vector control strategy. The study investigated
the species composition and indoor resting density of mosquito species in seven
communities in Bayelsa State, Nigeria. Adults were collected twice quarterly
using Pyrethrum Spray Catch (PSC) technique in 54 houses during September 2008
and August 2010. Mosquitoes were identified morphologically and characterized
based on their gonotrophic status as fed, unfed, gravid and half gravid. The
Indoor Resting Density (IRD) and Man Biting Rates (MBR) were determined. A total
of 4566 female mosquito belonging to 5 species in 3 genera (Culex, Aedes
and Anopheles) were collected. Species compositions in their increasing
order of abundance were: Culex quinquefasciatus (45.6%), An. gambiae
(24.2%), Ae. aegypti (18.1%), An. funestus (8.6%) and An. nili
(3.5%). Differences in species distribution across locations were significant
(fcal = 21.644, p<0.05). Over 80% of the mosquitoes were collected during
wet season. Indoor resting density of the mosquito species were: Cx quinquefascistus
(38.6 mosquito/room), An. gambiae (20.5 mosquito/room), Ae. aegypti
(15.3 mosquito/room), An. funestus (7.3 mosquito/room) and An. nili
(2.9 mosquito/room). About >40% of Cx quinquefasciatus and 70% of
An. gambiae were fed. Their Man-biting rates were 9.8 bites/person/night
and 8.7 bites/person/night, respectively. This study has contributed to the
understanding of the distribution and indoor resting behavior of mosquitoes
in Bayelsa State. The population of Culex and Aedes highlights the foci of filariasis
and yellow fever in this location. This is a cause for public health concern.}
