Laboratory evaluation of the insecticidal activity of camphor on the development of Oestrus ovis larvae.

The essential oil of E. globulus leaves or camphor against the maturation of Oestrus ovis larvae was evaluated at the laboratory conditions. Camphor at concentrations 1:0 and 1.1 showed 100% mortality rate. At concentrations of 1:2-1:6 the mortality rate ranged between 45-98%. On the other hand, 38 or 27.5% of the developed pupae emerged to adults but only 36.8% of them were fertile. Camphor is safely used in Medicine. So, it is recommended in controlling the zoonotic myiasis producer, O. ovis.
