AbstractIn order to quantify the outcome of sperm competition in the mating system of the rove beetle Aleochara curtula we performed three different mating experiment series. Paternity was established by DNA fingerprinting with oligonucleotide probes. We found a precedence of the last male with a proportion of eggs fathered by the last male of 87% (median). Nevertheless, we observed a large variation of P2-values in A. curtula and cases of mixed paternity were documented as well as cases of 100% or 0% paternity of the last male. The variation of P2-values correlates with the efficiency of spermatophore and sperm transfer.
