Mosquito Species Breeding in Ground Pools and Artificial Containers in Ajana, Ogun State, Nigeria

Abstract

During the 12 month period from August 2001 to July 2002, observations were carried out on the mosquito breeding that occurred in ground pools and a four types of test water containers – plastic, Aluminium, calabash and bamboo stumps placed in various locations in a rice field and within a village Ajana-Liyebi, Obafemi-Owode Local Government area, Ogun State, Nigeria. Eight mosquito specie were encountered in ground pools within the village and the rice field namely, Anopheles gambiae, n. moucheti, An. nili, An. subpictus, Aedes aegypti, Culex tigripes, Eretmapodites chrysogaster and Coquilledtidia fuscopennata. In the test containers 29 species of mosquitoes were encountered namely: Aedes africanus, Ae. aegypti, Ae. domesticus, Ae. albopictus, Ae. unilineatus, Ae. vittatus, Ae. taylori, Ae. kunmi, Ae. simulans, Ae. uteocephalus, Ae. metallicus Ae. hirsutus, Ae. simpsoni, Ae. longipaipis, ex. p. quiquefasciatus, Cx. dutoni, Cx. tellesila, Cx. tigripes. An. arabiensis, An. funestus, An. macultpennts, An. subpictus, Taeniorhyncus brevipalpis, Eretampodites chrysogaster, E. oedipus, Coquilletidia fuscopennata, Coq. mettalica, Mansonia africana and M. uniformis. In the ground pools, An. gambiae was the most abundant constituting 38.33% of the larvae encountered and appearing in 96.0% of the positive dips. Aedes aegypti was the most abundant in the test containers (29.57%) followed by M africana .10.10%) and Aedes simpsoni (9.45%). Calabash container harboured the highest number of larvae (36.0%) followed by bamboo stumps (24.2%) plastic ‘container 123.0%) Aluminium container harboured the least number of larvae (16.8%). No significant difference was observed in the total number of larvae collected in the different sites P > 0.05, however the number of larvae collected from the different containers was significantly different P < 0.05.
