title: Myxomatosis: the emergence of male and female European rabbit fleas Spilopsyllus cuniculi (Dale) from laboratory cultures.
abstract: The sex ratios and the emergence patterns of the European rabbit flea bred under animal house conditions were examined. An overall preponderance of female fleas was found. This was due to the greater preponderance of female fleas in the primary emergence, whereas the sex ratios in the secondary emergence were about 1:1.
