A Genetic determination of insemination frequency and sperm precedence in the german cockroach
1979
Cochran, Donald G.
By use of a recessive-genetic marker, it has been shown that adult female German cockroaches, Blattella germanica (L.), can be successfully inseminated by more than one male. Reinsemination was demonstrated to occur rarely between the first mating and production of the first egg case, while about 20% of the females examined remated between egg cases. The total impact of second matings on the offspring produced was small because of remating infrequency and the prevalence of incomplete sperm precedence in those that were inseminated.
