Infestation of legume root nodules by a chloropidan larva

Summary Nodules of cowpea and crotalaria were found to be heavily infested by the larva under field conditions resulting in the stunted growth of these plants. Artificial infestation of cowpea in pots showed that as much as 60% of the nodules were affected. A natural host-parasite relationship between crotalaria and the larva was also found to exist.
