[Chemoreceptor organs of the antennae and maxillary palps of fleas (Siphonaptera)].
Ultrastructure of chemoreceptor sensillae on antennae and maxillary palps of fleas of Ceratophyllus sciurorum is described. On antennae of fleas are the following types of sensillae: trichoid cuspidate and obtusate, fungoid, basiconical sensillae in olfactory fossae and on the surface of antennae. On maxillary palps there are trichoid cuspidate, basiconical and campaniform sensillae. A comparison was made of the composition and number of chemo- and mechanoreceptor sensillae in 14 species of fleas differing in the type of parasitism. It has been established that "nest" fleas have the greatest number of sensillae.
