BG642312 is necessary for increased egg laying levels at 24 hours after the start of mating. Females mated to BG642312^{dsRNA.Sym.Scer\UAS}-Scer\GAL4^αTub84B.PL knockdown males have reduced egg-laying at 24 hours after the start of mating, compared to controls. however, from 2 days on, the egg laying response of females mated to BG642312^{dsRNA.Sym.Scer\UAS} knockdown males is similar to control levels. As a consequence of normal levels of egg laying on days 2-10 after the start of mating, the total fecundity of females mated to BG642312^{dsRNA.Sym.Scer\UAS} knockdown males over a period of 10 days does not differ significantly from controls. The percent hatchability of the eggs laid by mates of BG642312^{dsRNA.Sym.Scer\UAS} knockdown males is affected only at 24 hours after the start of mating as a consequence of reduced egg laying, and fertility over a period of 10 days does not significantly differ from controls.

Females mated to BG642312^{dsRNA.Sym.Scer\UAS}-Scer\GAL4^αTub84B.PL males show low receptivity to re-mating 24 hours after the initial mating and normal receptivity after four days.
