Eficiencia del uso de feromona sintética y cebos vegetales en la captura del rhynchophorus palmarum l. en el cultivo de dátil (phoenix dactylifera).

Abstract

The black palm weevil is a pest that attacks many palm species in general, in its larval stage it feeds on the meristem, while in its adult stage it functions as a means of transmission of the disease called red ring disease of the palm, in these two cases, the action of this pest is responsible for causing the death of the crop, which is why the objective of this research is to evaluate the effectiveness of synthetic pheromones and plant baits in reducing the populations of the black palm weevil (Rhynchophorus palmarum L. ) in date palm (Phoenix dactylifera) crops. This study was carried out in the Cerecita area of the province of Guayas, in an experimental trial belonging to the Catholic University of Santiago de Guayaquil, during 4 weeks of experimental work, four different treatments were evaluated in a completely randomized experimental design, with a total of eight experimental units, one gallon containers were used to prepare the traps in which the commercial synthetic pheromone Rhyncolure® was placed, adding 600 ml of molasses solution plus water in concentration (2: 1) and three vegetable baits were 200 g of pineapple, papaya and guava, which were used to complement the treatments. As a result of this trial, treatment one, which is composed only of Pheromonal plus molasses, is the one that captured the most weevils and required the least investment cost.
