oa African Entomology - Results of a preliminary ovitrap survey for Aedes albopictus (Skuse) (Diptera: Culicidae) at two tyre retreading companies in Durban, South Africa



Surveillance for possible breeding populations of the exotic Asian mosquito Aedes albopictus (Skuse) was undertaken in Durban near the premises of the two largest importers of used tyres from the Far East. Water-filled bamboo pots were exposed as ovitraps from December 1991 to May 1992. Aedes aegypti (Linnaeus) was most prevalent, occurring in 2S-S2 % of pots at 0.14-0.60 mosquitoes/pot/day. Culex quinquefasciatus Say was found in S-24 % of pots at 0.0s-D.36 mosquitoes/pot/day. Three other species occurred sporadically. No Ae. Albopictus were collected, suggesting that this species has not become established in Durban.
