Eficiencia del uso de feromona sintética y cebos vegetales en la captura del picudo negro (Rhynchophorus palmarum) en el cultivo de palma africana (Elaeis guineensis Jacq.).

Abstract

The black palm weevil is an insect that in the larval stage feeds on the meristem of the stem and adult acts vector of the disease called red ring, in both cases, manages to cause the death of the palm, so the objective of this research is to determine the efficiency of the use of synthetic pheromone and vegetable baits in the capture of the black weevil (Rhynchophorus palmarum) in the cultivation of African palm (Elaeis guineensis Jacq.) which will be held in the canton Balzar. The research will be carried out during 4 weeks of experimental work in the field, for which a random block design (DBCA) will be used, in order to obtain more accurate data and skew factors difficult to control in the culture, four treatments with 5 repetitions will be evaluated giving a total of 20 experimental units, baskets of 20 L capacity will be used to make the traps, as well as the use of the synthetic pheromone plus 500 g of vegetable baits which were pineapple, sugar cane and palm seed (ozonated), plus the use of 600 ml of molasses to a solution of (2:1). It was the treatment with sugar cane as vegetable bait that obtained 40.29% efficiency, with an average of 9.20 males and 14.80 females captured and an investment cost of USD 79.75 per 5 hectares that indicate that it is viable for the use of palm growers in the areas for the control of this pest.
