Some Responses of Flying Aedes Aegypti to Visual Stimuli

The responses of adult Aedes aegypti L. to real and simulated linear movement at inanimate target areas were investigated. The results suggested that warmth and humidity together were of greatest influence in attracting flying A. aegypti, but a dark object at ambient conditions in the vicinity of a warm humid white target received almost equal attention from the flying mosquitoes. Incident illumination as low as 100 lux markedly reduced the attractiveness of an otherwise attractive surface. Movement had a consistently small but positive attraction, though the effects of this might be obscured by local air turbulence due to the motion.
