Systemic activity of the avermectins against the cat flea (Siphonaptera: Pulicidae).
Ivermectin has potent systemic activity against numerous species of nematodes and arthropods, but there are some important species in these two groups, such as the cat flea, Ctenocephalides felis (Bouché), that appear to be refractory to it. In an effort to determine if the lack of systemic activity against C. felis is specific to ivermectin, or if it is a class-wide phenomenon, 20 avermectin d...
متن کاملThe effects of diet upon pupal development and cocoon formation by the cat flea (Siphonaptera: Pulicidae).
Cocoon formation by cat flea larvae was directly related to the quantity of eggs or yeast consumed. Larvae consuming either 1-3 eggs or 0.25-1.0 mg of yeast developed as naked pupae or formed incomplete cocoons. Third instar cat flea larvae fed upon naked pupae and pupae within partial cocoons, but complete cocoons protected pupae from cannibalism. First and second instars did not attack pupae....
متن کاملDevelopment of microsatellites for genetic analyses and population assignment of the cat flea (Siphonaptera: Pulicidae).
Cat fleas, Ctenocephalidesfelis (Bouché) (Siphonaptera: Pulicidae), are common ectoparasites of companion animals that negatively impact their hosts directly by causing dermatitis and blood loss during feeding and indirectly through the potential transmission of disease causing agents. We isolated and characterized seven novel microsatellite loci from a partial genomic library of the cat flea e...
متن کاملAdult cat flea (Siphonaptera: Pulicidae) excretion of host blood proteins in relation to larval nutrition.
Protein content and ion composition of host blood and feces from blood-fed adult cat fleas, Ctenocephalides felis (Bouché), were examined. Total fecal protein differed slightly from host blood indicating that there was little digestion of host blood by adult fleas. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels of host blood and flea feces also revealed little digestion, as evid...
متن کاملIdentification of the Rdl mutation in laboratory and field strains of the cat flea, Ctenocephalides felis (Siphonaptera: Pulicidae).
In many insect species, resistance to cyclodiene insecticides is caused by amino acid substitutions at a single residue (A302) within the M2 transmembrane region of the gamma-aminobutyric acid (GABA) receptor sub-unit termed Rdl (resistance to dieldrin). These mutations (A302S and A302G) have also been shown to confer varying levels of cross-resistance to fipronil, a phenylpyrazole insecticide ...
