Insecticides against larvae of the cacao webworm Pansepta teleturga Meyrick (Lepidoptera: Xyloryctidae)
Thirty-five insecticides were screened for effectiveness against larvae of Pansepta teleturga, a woodborer in cacao trees. Several of the more promising insecticides were selected for field trials, using 1 or 2 of 3 methods of application: (i) spraying onto the web. (ii) application of systemic insecticides to the bark, and (iii) swabbing a dilute solution onto the feeding area. Swabbing was the only effective method. Endrin, azinophosethyl and dimethoate were the mos effective insecticides when swabbed. Dimethoate is recommended because of its comparatively low mammalian toxicity.
