| description | Schinus molle L. (Anacardiaceae) pepper tree is an ethnobotanical important plant belonging to Andean zone and is used as a botanical insecticidal agent for agricultural pest control. The ecotoxicological effects of aqueous extracts of the pepper tree on the following four non-target organisms were evaluated: Ceraeochrysa cincta (Schneider) (Neuroptera: Chrysopidae) eggs and firstinstar larvae, Chrysoperla asoralis (Bank) (Neuroptera: Chrysopidae) eggs and first-instar larvae, Telenomus remus Nixon (Scelionidae: Hymenoptera) adults, and Orius insidiosus Say (Anthocoridae: Hemiptera) adults. Five concentrations with increasing amounts of an aqueous extract from S. molle leaves (w/v) were employed: 1.5%, 2.5%, 5%, 10% and 20%. The parameters of acute toxicity employed were the lethal concentration (LC50) and the effective concentration (EC50). The following sequence in decresing order of ecotoxicity in terms of EC50/LC50 were found: C. cincta larval mortality (LC50 at 48 h = 3.7 %) > not hatched C. cincta eggs (EC50 = 5.1%) > O. insidiosus adults (LC50 at 48 h = 14.2%) > C. asoralis larval mortality (LC50 at 48 h = 32.2 %) > not hatched C. asoralis eggs (EC50 = 34.3%) > T. remus adults (LC50 a 48 h = 40.9%). Potential ecological risks of employing this botanical insecticide in Peruvian agroecosystems are discussed. A list of all eukaryotic species with toxicity and repellence of the pepper tree evaluated is included. |

(Anacardiaceae) molle es una planta de importancia etnobotánica originaria de la zona altoandina y usada artesanalmente como agente insecticida para el control de plagas agrícolas en el Perú. Se evaluó el efecto ecotoxicológico de extractos acuosos de molle sobre cuatro organismos no blanco: Ceraeochrysa cincta (Schneider) (Neuroptera: Chrysopidae) en huevos y larvas de primer estadío, Chrysoperla asoralis (Bank) (Neuroptera: Chrysopidae) en huevos y larvas de primer estadío, Telenomus remus Nixon (Scelionidae: Hymenoptera) en adultos y Orius insidiosus Say (Anthocoridae: Hemiptera) en adultos, bajo condiciones de laboratorio. Se emplearon cinco concentraciones acuosas de hojas de S. molle (p/v): 1.5%, 2.5%, 5%, 10% y 20%. Los parámetros de toxicidad aguda empleados fueron la concentración letal (CL50) y la efectiva media (CE50). Se encontró la siguiente secuencia en orden decreciente de toxicidad en términos de CE50/CL50: mortalidad larvaria de C. cincta (CL50 a 48 h = 3.7 %) > no eclosión de huevos de C. cincta (CE50 = 5.1%) > adultos de O. insidiosus (CL50 a 48 h = 14.2%) > mortalidad larvaria de C. asoralis (CL50 a 48 h = 32.2 %) > no eclosión de huevos de C. asoralis (CE50 = 34.3%) > adultos de T. remus (CL50 a 48 h = 40.9%). Se analiza la posibilidad de riesgo ecológico del empleo de este insecticida botánico en el agroecosistema peruano. Se incluye una lista de todas las especies eucariotas donde se ha evaluado la toxicidad y repelencia del molle.
