Reproductive strategies of the cat flea (Siphonaptera: Pulicidae): Parthenogenesis and autogeny?
Journal of Medical Entomology 33 (3), 395-397
Abstract: The objective of this study was to determine if there is evidence of parthenogenesis or autogenous reproduction in the cat flea, Ctenocephalides felis (Bouché). To examine parthenogenesis, 400 newly eclosed virgin female fleas were collected from a laboratory colony and 100 were placed into each of 4 feeding cages and fed bovine blood through a Parafilm membrane. Three of the feeding cages were monitored for egg production for 7 d and each group of 100 virgin female fleas produced an average of 1,119 eggs per cage, but none was viable. Fifty male fleas were added to those 3 feeding cages on day 7, and within 24 h the female fleas began ovipositing fertile eggs and nearly quadrupled their egg output. The other cage in which no males were introduced served as a control and did not produce a single viable egg in the 14-d experimental period. A similar experiment examined the continuance of virgin females to lay nonviable eggs and it was found that they continued to lay nonviable eggs for at least 58 d. Egg production was also studied in unfed fleas and it was found that unfed fleas did not produce eggs. These results suggest that neither parthenogenetic reproduction nor autogeny are exhibited by the cat flea.
