Using a 2.93 fb-1 data sample of electron-positron collisions taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, which corresponds to (8296±31±64)×103D+D- pairs, we search for the baryon and lepton number violating decays D+→Λ¯(Σ¯0)e+ and D+→Λ(Σ0)e+. No obvious signals are found with the current statistics and upper limits on the branching fractions of these four decays are set at the level of 10-6 at 90% confidence level.
