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... |

Homogeneous forests are susceptive to the occurrence of population’s boom of forest pests. Among them, the beetles are considered important economically, not only for the actual damages to the stand, but mainly for the difficulty of control. This work aimed to carry out a population survey of insects, mainly of xylophagous, in stands of Tectona grandis. Twenty ethanolic traps and 30 wood samples of teak were installed in two stands in the municipalities of Alegre and Cachoeiro de Itapemirim, located in the south of Espírito Santo State, Brazil. After 18 months (January of 2011 to July of 2012) adult insects, pupas and larvae in the existing galleries in wood samples were collected. The collections of the adult insects were carried out monthly in the... |
