| dc.description.abstract | The nature, size and position of the emergence holes made in the host pupal cases by different species of pupal parasitoids of the coconut caterpillar Opisina arenosella Wlk. (-Nephantis serinopa Meyr.) were studied. These criteria were used in developing a method to estimate the intensity of natural parasitism of the pest and the relative contribution of individual species of parasitoids in the natural suppression of the pest. The advantages of the method of examination of empty pupal cases are that it is less time-consuming, less cumbersome and more accurate than the currently adopted method of collecting sample pupae at periodic intervals and observing the emergence of parasitoids and evaluating the intensity of parasitism. | en_US |
