Numbers of An. arabiensis (log mean numbers/house) collected in houses in Ukaysh (a) between March 2004 and March 2005, with number of occupants (b) and presence or absence of televisions (c) in the same houses. Numbers of An. arabiensis were significantly higher (P < 0.001) in houses with televisions (5.7; 95 % CI 2.8–10.8) than those without (1.4; 95 % CI 0.8–2.1), and were positively correlated with the number of human occupants in the house (Pearson’s Bivariate correlation; r = 0.361; P = 0.005)
