<i>IN VITRO</i> EFFECTS OF SOME HOUSEHOLD CHEMICALS ON INFECTIVE LARVAE OF <i>HAEMONCHUS CONTORTUS</i> OF GOAT

Abstract

In vitro effects of some household chemicals on infective larvae (L₃) of Haemonchus contortus of goat were screened during the period from January 2002 to April 2003. Solutions of 0.5, 1, 5, 10 and 20 mg / ml were screened for in vitro effects on infective larvae (L₃) of Haemonchus contortus. The percent non-motile L₃ was increased when immersed in increasing solutions of the household chemicals (p < 0.01) except sodium chloride. Of 10 household chemicals, potassium permanganate showed 100% in vitro larvicidal effect at 1 mg / ml concentration. Boric acid showed the second highest larvicidal effect (78.95%) followed by alum (71.86%), bleaching powder (71.43%) and borax (68.97%) at their highest concentration of 20 mg / ml.
