Resumen
PEREZ, Diana D. y IANNACONE O., José. Mortality and repellence of Eupalamides cyparissias (Lepidoptera: Castniidae), pest of oil palm Elaeis guineensis, by effect of ten botanical extracts. Rev. Soc. Entomol. Argent. [online]. 2008, vol.67, n.1-2, pp.41-48. ISSN 0373-5680.
The plants with insecticide activities constitute a main compound of integrated pest management. Under this premise, the aim of the current research was to evaluate mortality and repellence of Eupalamides cyparissias Fab. (Lepidoptera: Castniidae) larvae, pest of oil palm Elaeis guineensis Jacquin, employing ten plants with insecticide potential: Indian heliotrope (Heliotropium indicum L., Boraginaceae), Angel´s trumpets (Brugmansia x candida Pers., Solanaceae), Wandering Jew (Tradescantia zebrina Hort ex Bosse, Commelinaceae), Nettles-purge (Jathropa curcas L., Euphorbiaceae), Soapberry (Paullinia clavigera Schltdl., Sapindaceae), Red spurge (Euphorbia cotinifolia L., Euphorbiaceae), Annato (Bixa orellana L., Bixaceae), Golden shower (Cassia fistula L., Fabaceae), Birthwort fruit (Aristolochia pilosa Kunth, Aristolochiaceae) and Pareira (Chondrodendron tomentosum Ruiz & Pavon, Menispermaceae). Bioessays with E. cyparissias were performed at 1 h and 24 h under standardized laboratory conditions. At 24 h exposure, the highest percentage of mortality of E. cyparissias was observed with Soapberry (63.3 %: bark and leaves in decoction), Annato (63.3 %: liquefied seeds) and Red spurge (48.3 %: liquefied leaves). In the case of repellence, the highest effects were found in Annato (83.3 %), Soapberry (75 %) and Angels´ trumpets (66.7 %: liquefied leaves).
