“…The human hand elicited significantly higher responses compared with either water vapour or temperature treatments These results confirm the findings of Daykin et al (1965), Khan & Maibach (1966), Daykin (1967), Smith et al (1970), Khan & Maibach (1972), Price et al (1979) and Gillies (1980). Using electrophysiological techniques, Kellogg (1970) demonstrated that females of A. aegypti were sensitive to a 2% increase in relative humidity.…”

The responses of female Aedes aegypti (Linnaeus) to a variety of stimuli were studied using an olfactometer bioassay. Mosquitoes responded significantly to convection currents produced by a human hand. The addition of water vapour to convection currents enhanced significantly the mosquitoes' response. Lactic acid, either alone or in combination with water vapour or/and convection currents however, did not increase the response level. Sweat extract elicited higher response than convection currents, water vapour and lactic acid. Human hands elicited significantly higher responses than any other stimuli. The presence of active chemicals other than lactic acid in human odour extract is discussed.

“…An important kairomone that is known to attract haematophagus insects is carbon dioxide (CO 2 ) (Takken, 1991) and for Aedes aegypti it must be present with other more speci®c host odours before attraction can be induced (Smith et al, 1970;Price et al, 1979). Anopheles gambiae is highly anthropophillic and is thought not to use CO 2 as its primary host-locating kairomone, but rather to employ more speci®c fatty acid compounds produced by bacteria present on human skin (Knols, 1996).…”

Abstract.Compounds from the odour-producing glands of the fox Vulpes vulpes were collected. This complex mixture of compounds was used to stimulate thè ascoid' olfactory organs of female sand¯ies in single sensillum and gas chromatography-linked single sensillum recordings. Sixteen of these compounds were identi®ed using gas chromatography-linked mass spectrometry and amounts present were determined. The compounds fell into four organic classes: ketones, carboxylic acids, alcohols and aldehydes. Speci®c neurones present in the ascoid sensillum that responded to each of these classes of compound were characterized. A bioassay chamber was developed that gave female sand¯ies the choice of two odour sources. Female sand¯ies were attracted upwind by fox odour and were trapped in closer proximity to the fox odour port than the control port. Synthetic compounds were recombined in appropriate quantities to mimic the fox odour. In this bioassay, the synthetic blend attracted sand¯ies upwind, and again they were caught closer to the test port than the control port. Furthermore, the synthetic fox odour induced an electrophysiological response from neurones in the ascoid sensillum that was very similar to that induced by natural fox odour. No synthetic compound alone induced the same behavioural response from sand¯ies as did whole fox odour. However, benzaldehyde, 4-hydroxy-4-methyl-2-pentanone and 4-methyl-2-pentanone alone did cause sand¯ies to¯y upwind and to be caught closer to the test port than the control.

“…Daykin et al (1965) and Khan and Maibach (1966) concluded on the basis of wind tunnel experiments that CO 2 in mosquitoes is not an attractant, only an activator. Although LA is effective as an attractant it is without effect unless CO 2 is in the air stream as well (Smith et al, 1970;Price et al, 1979). Summary of odour sources and compounds known as the result of field and/or wind tunnel work to attract biting flies to their hosts.…”
