Although variation in male fertilization efficiency has been shown to have a genetic basis in several species, the genes responsible for the effect are generally unknown. Here, we show a strong association between the fertilization success of males and their phosphogluconate dehydrogenase (Pgdh) genotype in the bulb mite Rhizoglyphus robini. Males(More)
Cellulose acetate electrophoresis (CAE) was used to investigate enzyme polymorphism in two congeneric species of Acaridae, Rhizoglyphus robini and R. echinopus. Using homogenates of individual mites, 27 enzymes were examined in two buffers. Five enzymes showed interspecific polymorphism, 15 exhibited intraspecific variation inR.robini and 12 in R.echinopus.(More)
We investigated the influence of mating frequency on lifetime reproductive success in females of the bulb mite, Rhizoglyphus robini. This species is highly promiscuous, and its colonial lifestyle promotes mating frequencies of at least several times a day. We manipulated mating frequencies either by keeping females continuously in the presence of a male,(More)
