| The objective of this study was to evaluate botanical oils, mineral oils and an insecticide that contained azadirachtin (ICA) for the control of Hypothenemus hampei, in addition to the effects of residual castor oil. We evaluated the effectiveness of the vegetable oils of canola, sunflower, corn, soybean and castor, two mineral oils (assist® and naturol®), and the ICA for the control of H. hampei. The compounds were tested at a concentration of 3.0% (v v-1). The median lethal concentration (LC50) was estimated with Probit analysis. The oil of castor bean and extract of castor bean cake were also evaluated at concentrations of 3.0% (v v-1) and 3.0% (m v-1), respectively. The mortality rates for H. hampei caused by the ICA and the castor oil were 40.8 and... |
