Susceptibility of the cat flea, Ctenocephalides felis (Siphonaptera: Pulicidae) to four pyrethroids.
The amounts of active ingredient required to kill adult Ctenocephalides felis fleas on filter insecticide impregnated papers were determined in an attempt to compare the activity of different active ingredients. The following compounds were tested: bioallethrin, deltamethrin, esbiothrin and permethrin. The LD50 and LD90 against Ctenocephalides felis were 121 and 770 mg/m2 respectively for bioallethrin, and 161 and 671 mg/m2 respectively for esbiothrin. For deltamethrin and permethrin, the LD50 were 0.38 and 23 mg/m2 respectively, and 15 and 60 mg/m2 respectively for LD90.
