Description
Summary:Plant extracts were studied to evaluate its efficiency in the control of Rhipicephalus (Boophilus) microplus (Canestrini, 1887) in laboratory. Engorged female ticks were collected from the cattle, kept in Petri dishes. Organic alcoholic extracts 2% (weight/volume) were used: seeds of Annona muricata L. (Annonaceae) (soursop); flowers of Syzygium malaccensis (L.) (Myrtaceae) (iamb), leaves of Cymbopogon citratus (DC.) Stapf (Poaceae) (holy grass), leaves of Azadirachta indica A. Juss (Meliaceae) (neem) and hexane extract 2% (weight/volume) of A. indica (seeds). The control groups consisted of untreated females and females treated with distilled water and sterile and dimethylsulfoxide (DMSO) a concentration of 1%. The extract of A. muricata (seed) had the highest mortality with acaricide activity and 100% efficacy followed by extracts of S. malaccensis (75 and 59.24%) and A. indica (65 and 38.49%). The seed extract of A. muricata reduced 100% larvae hatch.
