INFLUÊNCIA DA COR EM ARMADILHAS MODELO MCPHAIL PARA ATRAÇÃO DE MOSCA-DAS-FRUTAS EM POMARES DE PESSEGUEIRO

In order to investigate the influence of baited-trap color on fruit fly attraction, two McPhail trap models were used to monitor the insect in peach trees. One of the models was constructed of clear plastic, while the other had a clear top and a yellow bottom (base). The traps were installed in pairs, on five plants spaced 30 m apart. Traps were monitored twice a week from 12/20/2005 to 01/13/2006, with trap rotation at each evaluation, switching trap position in the tree. The yellow-bottomed McPhail traps were not superior to the clear ones during the evaluations, and no fruit fly capture increases were observed due to the yellow color.
