PARASITES. 
Pegomya planipalpis is attacked by two chaleidid parasites. One 
(ITolaspis n. sp.) belongs to a genus of which there are two known 
species, Holaspis parellina Boh. and I. papaveris Thoms., recorded ! as 
parasitic on Cecidomyia spp. The other parasite (not yet determined ) 
reared from the legume pod maggot is probably also new to science. 
REMEDIAL AND PREVENTIVE MEASURES. 
This maggot has not as yet become a serious factor in field-pea 
seed growing in the Pacific Northwest. The dissemination as 
hibernating puparia can be readily prevented by fumigation. As is 
the case with the legume pod moth, it can not be exterminated because 
of the native lupines.
