Larvicidal potential of Sapindus saponaria to control the cattle tick Boophilus microplus
The objective of this study was to evaluate the larvicidal potential of a crude ethanol extract (CEE) of soapberry Sapindus saponaria stem peel on the cattle tick Boophilus microplus. Tick larvae obtained by incubating engorged females, collected from naturally infested cattle, were placed in envelopes of filter paper impregnated with different concentrations of CEE in the test group, and distilled water in the control group. Four repetitions were made with each solution (n>120). Mortality was observed after 48 hours. Lethal concentration values of 1,258 ppm (LC50) and 6,360 ppm (LC99) were obtained.
