SHORT REPORT - INFLUENCE OF CENTERS-FOR-DISEASE-CONTROL LIGHT TRAP POSITION, RELATIVE TO A HUMAN-BAITED BED NET, ON CATCHES OF ANOPHELES-GAMBIAE AND CULEX-QUINQUEFASCIATUS IN TANZANIA

The best position for Centers for Disease Control (Atlanta, GA) light traps, in relation to human-occupied bed nets for trapping of host-see king Anopheles gambiae Giles and Culex quinquefasciatus Say mosquitoes , was determined in Tanzania. Significantly higher catches were record ed for both species when the trap was positioned at the foot end of th e bed, near the top of the net. Parity rates were significantly higher near the top of the net than at the level of the host. Since trap pos ition affects the catch size and the proportion of infectious mosquito es therein, standardized use of this sampling technique for estimating entomologic inoculation rates (i.e., the number of potentially infect ious bites received over a certain period of time) is recommended.
