|Phenotype Manifest In|
CheB42aΔ5-68 mutant males perform an average of eight attempted copulations in a 10 min observation period, whereas control males perform only three. This increased number results from a faster progression from initiation of courtship behaviour to the first attempted copulation, as well as more frequent subsequent attempts. CheB42aΔ5-68 males are not different from controls in the timing or frequency of earlier steps in the courtship sequence (lag to courtship initiation, tracking and following of the female, tapping, and wing vibration). CheB42aΔ5-68 homozygous males spend the same amount of time courting females as wild-type controls. CheB42aΔ5-68 has no effect on several other behaviours unrelated to courtship; such behaviours include preening, walking, geotaxis, and gustatory response to sugars.
CheB42aΔ5-68 has mating rhythm defective phenotype, enhanceable | male limited by Scer\GAL4oeE/traScer\UAS.cFa
CheB42aΔ5-68 has mating rhythm defective phenotype, suppressible | female limited by traScer\UAS.cFa/Scer\GAL4hs.PB
|Phenotype Manifest In|
In contrast to their different responses to wild-type females, CheB42aΔ5-68 and wild-type males attempt to copulate with heat-shocked females expressing traScer\UAS.cFa under the control of Scer\GAL4hs.PB with indistinguishable frequency and kinetics, suggesting that the behavioural effect of CheB42a depends on the presence of the major female cuticular hydrocarbons. Partially-transformed males, where traScer\UAS.cFa under the control of Scer\GAL4oeE is expressed in the oenocytes, elicit significant courtship responses both from controls and CheB42aΔ5-68 males. Mutant males outperform controls specifically in the kinetics and frequency of attempted copulations.
