| Abstract | ||
| Bathyplectes curcurlionis (Thomson) is the sole parasitoid encountered in west Baghdad parasitising larvae of alfalfa weevil Hypera postica (GylIenhal). Percent of parasitisation did not exceed 8% in 1989 and 1990 and overall rate of parasitisation was 5%. Additional reduction in percent of parasitisation caused by presence of the fungal pathogen Erynia phytonomi. High survival percent of weevil's larvae under the study conditions explains why this insect is a key pest of alfalfa. Suggestions were made to inhance the role of B. curcurtionis in controlling the weevil. | ||
