Efficiency of the latex from Euphorbia splendens var. hislopii (N.E. Br.) Ursch & Leandri, Euphorbiaceae, in the control of Rhipicephalus (Boophilus) sanguineus (Latreille, 1806) (Acari: Ixodidae)
Abstract:Abstract:The aim of this study was to evaluate the effect of the latex from Euphorbia splendens var. hislopii (N.E. Br.) Ursch & Leandri, Euphorbiaceae, on the eggs and engorged larvae of Rhipicephalus (B.) sanguineus (Latreille, 1806) (Acari: Ixodidae). Six aqueous concentrations: 25, 50, 100, 125, 250 and 500 µL/L of the latex of this plant were tested. The control group was tested only with distilled water. The latex of E. splendens var. hislopii presented an LD50 of 18.031 µL/L and LD90 of 84.610 µL/L agai… Show more
