摘要
Larvae of Eleodes spp., known as false wireworms, have been occasionally registered attacking seeds and seedlings of different plant species grown in the cold climate of the Cundi-Boyacense Highlands of Colombia. They seem to be pests of agricultural importance to plants in greenhouses at similar to 24 degrees C. Damage observed for the first time by larvae of this tenebrionid identified as Eleodes longicollis punctigerus Blaisdell acting as a cutworm of tomatoes, Solanum lycopersicum L., with long-shelf life in greenhouses was evaluated and characterized at the Universidad de Ciencias Aplicadas y Ambientales U.D.C.A. Damage to recently-transplanted seedlings ranged from 15 to 72%, necessitating reseeding, which considerably increased production costs. A significant relationship (Spearman's 0.92) was found between the percentage of cut seedlings and mean number of larvae per site. The use of carbaryl-based toxic bait controlled the pest satisfactorily, killing many larvae, which allowed estimation of the population within the greenhouse. This report could be of importance to other tomato-growing regions because the genus Eleodes is widely distributed from Canada to Mexico and probably farther south.
