Control of chicken body louse and dog ticks using some new pyrethroids

ABSTRACT

The present study was carried out to evaluate the efficacy of some new pyrethroids [Bayticol and Butox], as well as Ivomec through many routes of application against chicken body louse [Menacanthus spp.] and dog ticks [Rhipicephalus spp.]. The results revealed that Bayticol 1% in a dose 1 ppm/kg and Butox 7.5% in a dose 2 ppm/hen, have good efficacy for complete eradication of lice after 24 hours through pour-on application method. Also, the same dose gave the same results after 24 and 48 hours of Bayticol and Butox, respectively, through spot-on method, meanwhile Ivomec overcome the two pyrethroids through s.c. injection route concerning eradication of dog tick. The three tested insecticides give complete eradication of ticks in the high tested doses [Bayticol 10 ppm/10 kg, Butox 10 ppm/animal and Ivomec 100 mug/kg b. wt.] through pour-on and spot-on methods. In lower doses, the two pyrethroids [Bayticol and Butox] were more efficient through pour-on and spot-on methods, while Ivomec was the best one through s.c. injection. The laboratory trial revealed that Ivomec 1% considered as the best insecticide causing rapid mortality and prevent egg deposition and hatching under the tested dose in the laboratory. Using the insecticide for control of chicken body louse through pour-on and spot-on ways on the back of the chicken only were tested for the first time as method of application in chicken
