| Se realizaron experimentos para determinar la preferencia de color de trips (Frankliniella occidentalis Pergande) en cultivos de pimiento (Capsicum annum L.), en las localidades de Cerrillos de Tamaya (30° lat. S.; 71°16 long. O) y Pan de Azúcar (29°55 lat. S; 71°14 long, O) de la IV Región de Chile. En diseño de bloques completos al azar, se compararon trampas de pegamento azul, blanco, blanco-azul y amarillo.Los resultados mostraron que F. occidentalis fue la especie predominante en el cultivo de pimiento. En la trampa de color azul, blanco-azul y blanco se capturaron significativamente más trips que en las trampas amarillas, cuando las capturas fueron superiores a 300 trips semanales por trampa. Los resultados fueron erráticos con capturas inferiores. |

| Potato tuber moth (PTM), Phthorimaea operculella (Zeller), is one of the pests that cause the most damage to potatoes (Solanum tuberosum L.) in both field crops and storage, especially in regions where summers are hot and dry. Larvae develop in the foliage and tubers of potatoes and cause direct losses of edible product. The use of synthetic pheromones that interfere with insect mating for pest control has been widely demonstrated in numerous Lepidoptera and other insect species. An experiment was carried out during the 2004-2005 season in Valle del Elqui, Coquimbo Region, Chile, to evaluate the effectiveness of different pheromone trap densities to capture P. operculella males for future development of a mass trapping technique, and a subsequent decrease... |

| Potato tuber moth (PTM), Phthorimaea operculella (Zeller), widely world distributed, is one of the most serious insect pest attacking potatoes (Solanum tuberosum L.). Larvae develop in foliage and tubers of potato causing direct losses of edible product. Chemicals treatment to control this pest have shown limited efficacy, especially when larvae is under the soil. The utilization of synthetic pheromones as a tool that interferes with insects mating had been widely demonstrated in numerous moth and others insects species. With the objective to evaluate the efficacy of different doses of pheromone per trap in PTM males captures for its future utilization as a mass trapping technique, two experiments in a complete randomized blocks design, were carried out at... |

| Animal production units with different management systems can be found along the Huasco Valley, Region of Atacama, Chile. These constitute sources of house flies (Musca domestica L.) and other vector fly species that cause damage to animals and nuisance problems in urban areas. In order to asses the importance of fly breeding sources, an experiment was carried out under laboratory conditions to evaluate different types of animal manure and composted swine manure. Time of larval development, larva mortality, pupa size, and weight and time of development to the adult stage were assessed. Results show that swine, poultry and calf manure produced a significantly higher number of adult flies, shorter life cycles and larger and heavier pupae. Cow, dog, goat and... |

| Durante las temporadas de 2001-2002 y 2002-2003 se realizó una prospección de virus en pimientos (Capsicum annuum L.) en diversas localidades de la Región de Coquimbo (29,5-32° lat. Sur). La determinación de virus se realizó mediante la prueba DAS- ELISA. La importancia relativa de los virus encontrados para ambas temporadas fueron: Virus del mosaico del pepino (CMV) 23,3%; Virus del bronceado del tomate (TSWV) 20,8%; Virus del mosaico de la alfalfa (AMV) 14,8%;Virus Y de la papa (PVY) 14,5% e Impatients necrotic spot virus (INSV) 3,1% (primera identificación de este virus en pimiento en Chile); Virus del mosaico del tomate (ToMV) 2,2% y Virus del mosaico del tabaco (TMV) 4,9%. Los resultados indicaron que al menos el 30% de las muestras estaba infectada... |
