Abstract
The red palm weevil (Rhynchophorus ferrugineus F.)> is an enemy of young coconut palms. It bores into the tissues and ultimately kills the palm. Being a hidden enemy, timely detection is necessary for effecting control. Traps and attractants, by which adults can be trapped and kilted have proved to be effective components of integrated pest management. Log traps consisting of tender coconut stems, 50 cm long and spilt longitudinally were found to be superior to metal traps. The cut surfaces were treated with candidate attractants. Macerated fruits, molasses (jaggery from sugarcane) and toddy, singly or in combination, were die test materials. Along with these, yeast and/or acetic acid was mixed to ascertain whether the same will enhance the attractiveness. Out of sixteen combinations tested in the field, logs treated with coconut toddy+yeast+acetic acid were the best, followed by coconut toddy+ acetic acid, pineapple + molasses+yeast, pineapple + molasses, and molasses + yeast. The use of coconut log traps treated with the above combination is recommended as one of the effective components of integrated pest management.
