Abstract

GALINDO P, JULIO RICARDO  and  ESPANOLA, JEANNETTE AMPARO. Capture dynamic of Premnotrypes vorax (Coleóptera: Curculionidae) and the Guatemalan potato tuber moth Tecia solanivora (Lepidoptera: Gelechiidae) in traps with different types of attractants in a potato crop (Solanumphureja). Rev. Colomb. Entomol. [online]. 2004, vol.30, n.1, pp.57-64. ISSN 0120-0488.

In the Experimental Center of Corpoica Tibaitatá, a crop of Solanum phureja was followed during the entire developmental cycle to evalúate capture dynamics of the potato weevil and the Quatemalan potato tuber moth, considering two periods: before and after hilling. The traps used were selected from previous work that showed high capture and usefulness for evaluating behavior of the insect of interest. for the potato weevil, net pitfall traps that contained parts of the potato plant as attractant, and traps that contained the same insect in group of males and females as attractants, were used. Traps recommended by the Centro Internacional de la Papa (CIP) were used as controls. Each kind of trap reflected insect activity in different ways and together showed two stages of the crop in which adult potato weevils had a greater activity, which were emergence and flowering of the crop. In the case of the Quatemalan potato tuber moth, white sticky traps and traps that contained females of the same insect as an attractant, were used. Adult capture data were also taken from the pheromone traps. The different traps showed two different crop stages in which adult Quatemalan potato tuber moths showed greatest activity, which were tuber initlalization and physiological maturity of the crop.
