Abstract
To know the comparative attractiveness of black light and white or blue ones to biting midges and mosquitoes, a light trapping was carried out during July to September, 1963, at a poultry house in the Shizuoka Prefectural Chicken Breeding Station. Black light always attracted more numbers of biting midges and mosquitoes, especially Culicoides arakawae, Culex tritaeniorhynchus, and Anopheles hyrcanus comparing with white or blue light, but the ratios of the attractiveness considerably varied with species and sex of the insects or days collected.
