Abstract
Objective: Evaluate three proportions of alcohol in traps with one and three windows and two different colors to capture Hypothenemus hampei Ferrari in the Paradise, Guerrero.
Design/methodology/approach: 3 mixtures of ethyl:methyl alcohol was evaluated in different proportions (1:0, 0:1 and 1:1), in addition, traps were used in green and transparent colors, designed with one and three windows. A complete factorial design was used, the distribution of treatments was done in complete blocks at random with four repetitions. The variables evaluated were the number of bits captured, water loss, evaporation of the attractant and percentage of damaged fruits. Evaluations were conducted in March–July 2007.
Results: There were differences between the treatments (p <0.05). Mix with 1: 1 was the best treatment, recorded an average catch of 980 trap insects week-1. In water loss the traps with a window were better than those designed with three, they recorded an average loss of 1,129.79 mL. The transparent color in traps is more efficient to prevent water loss, recorded an average loss of 905 mL.
Limitations on study/implications: The design and color of the trap do not influence the capture efficiency and evaporation of the attractant.
Findings/conclusions: The use of handcrafted traps of transparent color, with a window and with ratio of 1:1 ethyl and methyl alcohol, are very efficient in the trap for the control of H. hampei
