Evaluation of organic attractants to catch adult Opsiphanes cassina felder, oil palm defoliator

Con el proposito de evaluar la eficiencia de atrayentes para la captura de adultos de Opsiphanes cassina, fueron conducidos dos ensayos donde se evaluo una formulacion basica compuesta de: melaza, levadura y urea, en las dosis de 1 litro (l), 15 g y 10 g, respectivamente. Para el primer ensayo se evaluaron los siguientes tratamientos: Testigo (mezcla de 1 l de melaza + 150 g levadura); y otros 5 tratamientos representados por la formula basica diluida en 1,00; 0,75; 0,50; 0,25 y 0,00 l de agua. El segundo ensayo fue similar al primero, pero se incorporo un tratamiento con la formula basica disuelta en 1,25 l de agua. Se coloco 100 ml del atrayente en un recipiente de 250 cc, en una trampa consistente de una bolsa plastica transparente de 1,00 m de altura y 0,60 m de ancho. Los ensayos se efectuaron en la Agropecuaria El Aguila de la Empresa Palmonagas y se evaluaron con frecuencias de 2 a 4 dias. Los tratamientos fueron distribuidos en el diseno bloques al azar con 4 repeticiones. Los valores de captura se transformaron en mariposas/trampa/dia, permitiendo determinar la fluctuacion poblacional del insecto en los ensayos; los mismos se analizaron estadisticamente y se compararon por la prueba de Tukey al 5% de probabilidad. Se constato que los tratamientos constituidos por la formula basica diluida en 1,00 o 0,75 l de agua presentaron las mayores capturas y no difirieron estadisticamente. Se recomienda incorporar estos tratamientos en un programa de manejo integrado del insecto In order to evaluate the efficiency of some attractants for the capture of adults of Opsiphanes cassina, two experiments were carried out, in which a basic formulation of molass, yeast and urea were evaluated, in doses of 1 liter, 15 g and 10 g, respectively. In the first experiment the following treatments were evaluated: control (a mixture of molass + 150 g of yeast) and five additional treatments, with the basic formulation diluted into 1.00; 0.75; 0.50; 0.25 and 0.00 liters of water. The second experiment was similar to the first one, but it had one more treatment, represented by the basic formula dissolved in 1.25 liters of water. 100 ml of each attractant in a recipient of 250 cc were placed in a trap consisting of a transparent plastic bag of 1.00 m high and 0.60 m wide. The experiments were conducted at the Agropecuaria El Aguila, of the Palmonagas Company and they were evaluated with frequencies from two to four days. The treatments were arranged in a random block design with four replications. The values of capture were transformed in moths/trap/day to determine the insect population fluctuation in the essays, this values were analyzed statistically and their mean compared using the Tukey test at 5% of probability. The treatments with the basic formulation, with 1.00 or 0.75 liters of water, shown the largest captures, and there were not statisticals differences between them. This mix can be used in a program of Integrated Pest Management
