We evaluated the effectiveness of the vegetable oils of canola, sunflower, corn, soybean andcastor, two mineral oils (assist® and naturol®), and the ICA for the control of H. hampei. The compoundswere tested at a concentration of 3.0% (v v-1). The median lethal concentration (LC50) was estimated withProbit analysis. The oil of castor bean and extract of castor bean cake were also evaluated at concentrationsof 3.0% (v v-1) and 3.0% (m v-1), respectively. The mortality rates for H. hampei caused by the ICA and thecastor oil were 40.8 and 53.7%, with LC50 values of 6.71 and 3.49% (v v-1), respectively. In the castor oil, themethyl esters of the fatty acids were palmitic (1.10%), linoleic (4.50%), oleic (4.02%), stearic (0.50%) andricinoleic acids (88.04%). The extract of the castor bean cake was not toxic to H. hampei. The persistence ofthe castor oil in the environment was low, and the cause of mortality for H. hampei was most likely theblockage of the spiracles, which prevented the insects from breathing. 2016 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303044042001 https://www.redalyc.org/journal/3030/303044042001/ https://www.redalyc.org/journal/3030/303044042001/html/ https://www.redalyc.org/journal/3030/303044042001/303044042001.epub https://www.redalyc.org/journal/3030/303044042001/movil en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
