Changes in the relative frequency of occurrence of infestations of two sympatric species of bedbug in northern Natal and KwaZulu, South Africa.
Between 1983 and 1988 the frequency of Cimex hemipterus infestations relative to C. lectularius increased near the Mozambique border and around main roads in the Nkundusi-Mfekayi area of South Africa (28 degrees 15'S; 30 degrees 23' E). In areas where both species were common, the observed number of doubly-infested huts equalled the expected. A hut infested by both bedbug species showed a significant change to a higher proportion of C. hemipterus in the adult population over 2 months. The general increase in C. hemipterus is thought to be due to the large influx of migrants into South Africa in recent years.
