Sampling mosquitoes with CDC light trap in rice field and plantation communities in Ogun State, Nigeria.
Mosquito species were sampled to determine the mosquito composition and abundance in rice field and plantation communities in Ogun State Nigeria. Mosquitoes were caught once weekly from four selected houses in each of the two communities by means of CDC light traps. A total of 47,501 mosquitoes representing fifteen species were caught in the two communities of which the rice field community accounted for 63.8% of the total catch. Mansonia africana constituted the most important biting mosquito in the two communities representing 62.1% and 39.1% in rice field and plantation communities, respectively. Other species in decreasing order of abundance were M. uniformis, Anopheles gambiae, Coquilletidia fuscopennata, An. moucheti, An. funestus, An. nili, Culex quinquefasciatus, Eretmapodites chrysogaster, Coq. metallica, Cx. annulioris, An. rhodesiensis, Aedes aegypti, An. squamosus and An. maculipennis. Seven mosquito species were caught throughout the year but mostly in the months of May to October. Abundance varied significantly between the study sites and between the months (F,1.11 =241.9 P<0.05) Most of the mosquitoes collected were unfed and nulliparous (87.1%). In spite of the high proportion of M. africana, its parous rate was low 0.53 and 0.59 in rice fileld and plantation, respectively. The highest parity was seen in Ae. aegypti (0.81-0.86) and An. gambiae, (0.69-0.68).
