The tick Rhipicephalus (Boophilus) microplus is an endemic pest of cattle.
We investigated the effects of 3β-O-tigloylmelianol from Guarea kunthiana on cattle tick.
The new protolimonoid 3β-O-tigloylmelianol acts on oogenesis and ecdysis of the tick.
This compound is an alternative to environmentally hazardous synthetic acaricides.
