Evaluacion de la Proteina Hidrolizada de Maiz Para la Captura de Lonchaea Cristula (Diptera: Lonchaeidae) Plaga de la Curuba En El Valle Del Cauca

Abstract

This study tested the efficiency of hydrolyzed corn protein in capturing adults of Lonchaea cristula Mc-Alpine (Díptera: Lonchaeidae), whose larvae cause the loss of floral buds in a cultivated passion flower, "Curuba de Castilla" (Passiflora mollissima (H.B.K.) Bailey). Field work was carried out in two fields or curuba located in Tenerife, town of Cerrito, Valle del Cauca, at 2510 m (mean annual temperature 14, 1°C; relative humidity 75.2%).

Four different solutions of Hydrolized corn protein were tested: 1) 10% solution with sugar; 2) 10% solution without sugar; 3) 5% solution with sugar; 4) 5% solution without sugar. Mc Phail traps were baited with these solutions. The traps were set out during three months; their contents were changed and examined every 15 days.

Ninety-six per cent of 22148 specimens captured belonged to the genus Lonchaea. The results show that Hydrolized corn protein a highly specific attractant for these insects. The highest numbers of capture were obtained with 10% solution with sugar and 5% solution without sugar.
