A few chemical words exchanged byDrosophila during courtship and mating

Variation in cuticular hydrocarbons among strains of the Anopheles gambiae sensu stricto by analysis of cuticular hydrocarbons using gas liquid chromatography of larvae

“…In some insects, part of the mate recognition mechanism has been linked with the detection of specific hydrocarbon compounds and other components of the cuticular lipid layer e.g fatty acids, alcohols, sterols, aldehydes etc. (Jallon 1984, Bonavita-Courgourdan et al 1987, Pescke 1987.…”

Effects of the hypoactive and inactive mutations on mating success in Drosophila melanogaster

“…(1982) and Jallon (1984) males need to perceive female movement to initiate courtship and court immobilised females with far less intensity than wild type females. This contrasts the findings of Bastock (1956), Ewing (1963 and Kyriacou et a!.…”

“…Gas chromatographic analyses on a capillary column using hexane extracts from wild type and inactive individuals of both sexes were compared with those for Canton-S wild type flies described previously (Jallon, 1984). All major peaks comigrated with those of the reference strain.…”

“…5 l were then injected into a Girdel 300 gas chromatograph equipped with a Chrompack 25 m CpSil 5 capillary column. After integration with a Spectraphysics SP4270 integrator, chromatograms were compared within each group and with the reference chromatograms of D. melanogaster Canton-S males and females reported by Jallon (1984) and Antony et a!. (1985).…”

“…Following the procedure of Jallon (1984), five individuals of each sex and genotype were bathed in 50 pi hexane for five minutes and then vortexed. 5 l were then injected into a Girdel 300 gas chromatograph equipped with a Chrompack 25 m CpSil 5 capillary column.…”
