Mark-release-recapture experiments to estimate the efficiency of the light trap in collecting Japanese encephalitis vector mosquitoes

Abstract

Efficiency of the light trap in collecting females of Culex tritaeniorhynchus, the principal vector mosquito of Japanese encephalitis, was evaluated by mark-release-recapture experiments. Females collected with dry ice in the field were marked and released in a pigsty. The recapture rate of marked females by the light trap was so low as around 1% or lower. Owing to this low efficiency, it is not likely that the light trap can be a useful tool in the control of Japanese encephalitis. © 1995, National Institute of Infectious Diseases, Japanese Journal of Infectious Diseases Editorial Committee.
