Edgar Varón Devia Tito Bacca Arturo Carabali Agrociencias Fruit farm altitude farm management morphological description Avocado 'Hass' is a product with export potential, but damage caused by boring insects restricts its cultivation in the north of Tolima (Colombia). In order to promote its management, we established the breeding of the species with individually affected fruit. We determined the number of days in the pupal stage in order to observe the morphology and determine the extent of damage to the fruit at harvest. Tub breeding chambers and butter boxes were the most suitable for breeding ( P ≤0.05) with sterile soil or absorbent towels and disinfection of the fruit with sodium hypochlorite 2%. The observed borer had external morphological characteristics consistent with the specie Heilipus lauri Boheman (Coleoptera: Curculionidae). The insects pupate at 65.3 ± 1.42 days, with the pupal stage at 15.14 ± 0.33 days and emergence at 80.1 ± 1.36 days. Damage to fruit caused a perforation in the epidermis with the presence of a black circular crust, and presence of whitish excreta and boring of the larva in the pulp and seed. Evaluation of 12 trees on eight farms in the municipalities of Fresno and Herveo recorded 0.03 and 3.21% fruit damage (weight) respectively. The multiple regression analysis (stepwise) showed that the amount of plating/year is correlated with the percentage of infested trees (P≤0.05 and r 2 = 0.73). 2010 artículo científico 0122-8706 https://www.redalyc.org/articulo.oa?id=449945029004 es http://www.redalyc.org/revista.oa?id=4499 Ciencia y Tecnología Agropecuaria application/pdf Corporación Colombiana de Investigación Agropecuaria Ciencia y Tecnología Agropecuaria (Colombia) Num.2 Vol.11 |
