There is a significant drop in the courtship index (CI, the fraction of time spent performing any of the steps of courtship) of mutant males. They are capable of all courtship steps, but perform them less frequently. Short-term locomotor activity is unaffected. The male courtship phenotype is still observed if mutants are deprived of visual input or paired with young/mature virgin females. Mutant males do not show increased male-male courtship.
hecf06077 male flies missing the third antennal segment show significantly reduced courtship compared to control males under red light.
hecf06077 has abnormal mating behavior | male limited phenotype, enhanceable by fru[+]/fru4
hecf06077 is rescued by hecUAS.cLa/Scer\GAL4hec.PL
hecf06077 is rescued by Scer\GAL4fru.P1.D/hecUAS.cLa
Expression of hecScer\UAS.cLa using Scer\GAL4hec.PL or Scer\GAL4fru.P1.D completely rescues the courtship phenotype of hecf06077 males.
Expression of hecScer\UAS.cLa only in adult mature males using Scer\GAL4hec.PL or Scer\GAL4fru.P1.D together with the Scer\GAL80ts.αTub84B system completely rescues the courtship phenotype of hecf06077 males.
