The information about the species is scarce and it is required to estimate its distribution, fluctuation, and density, in order to design integrated pest management strategies.&nbsp;<strong><span class="CharOverride-2">Objective.</span>&nbsp;</strong>To evaluate food attractants as a sampling mechanism of&nbsp;<span class="CharOverride-4">Melanoloma viatrix</span>&nbsp;Hendel.&nbsp;<strong><span class="CharOverride-2">Materials and methods.&nbsp;</span></strong>The tests were carried out in pineapples farms in the municipality of Giron, Santander, Colombia, during the beginning of the first rainy season of 2003. Eight food attractants were evaluated within McPhail traps located in six random blocks within three commercial pineapple crops of the Perolera variety.&nbsp;<strong><span class="CharOverride-2">Results.&nbsp;</span></strong>The McPhail trap food attractant tests captured more than 13 000 individuals, including diptera, lepidoptera, hymenoptera, neuroptera, hemiptera, and orthoptera, but only 138 specimens of the study species.&nbsp;<strong><span class="CharOverride-2">Conclusion.</span>&nbsp;</strong>Significant differences were observed in the captures of&nbsp;<span class="CharOverride-4">M. viatrix</span>, being pineapple rind pieces, pineapple rind extract and natural pineapple juice the attractants that presented the best capture results.</p> ER -
