A premature stop codon has been introduced into the Zn-finger containing "B" alternative 3' exon. A NheI site has also been introduced into the B exon.
Homozygous male and female animals die as pupae.
The muscle of Lawrence forms in fruΔB/Df(3R)fru4-40 males, as occurs in wild type.
Compared to controls, fruΔB/Df(3R)fru4-40 males show a significant delay in latency to courtship and a significantly reduced courtship index towards females. Levels of copulation are also reduced, while those males that do mate are significantly delayed in the tim taken to successfully copulate. The males show normal levels of fertility over a one-week observation period. fruΔB/Df(3R)fru4-40 males show some chaining behaviour (forming male-male courtship chains).
The interpulse interval of the courtship song is significantly longer than normal in fruΔB/Df(3R)fru4-40 males.
