AB  - 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 (<I>Culex, Aedes 
  and Anopheles</I>) were collected. Species compositions in their increasing 
  order of abundance were: <I>Culex quinquefasciatus</I> (45.6%), <I>An. gambiae</I> 
  (24.2%), <I>Ae. aegypti</I> (18.1%), <I>An. funestus</I> (8.6%) and <I>An. nili</I> 
  (3.5%). Differences in species distribution across locations were significant 
  (fcal = 21.644, p&lt;0.05). Over 80% of the mosquitoes were collected during 
  wet season. Indoor resting density of the mosquito species were: <I>Cx quinquefascistus</I> 
  (38.6 mosquito/room), <I>An. gambiae</I> (20.5 mosquito/room), <I>Ae. aegypti</I> 
  (15.3 mosquito/room), <I>An. funestus</I> (7.3 mosquito/room) and <I>An. nili</I> 
  (2.9 mosquito/room). About &gt;40% of <I>Cx quinquefasciatus</I> and 70% of 
  <I>An. gambiae</I> 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.
