PARASITES. 



Pegomya planipalpis is attacked by two chalcidid parasites. One 

 (Holaspis n. sp.) belongs to a genus of which there are two known 

 species, Holaspis parellina Boh. and //. papaveris Thorns., recorded x as 

 parasitic on Cecidomyiaspp. The other parasite (not vet determined) 

 reared from the legume pod maggot is probably also new to science. 



REMEDIAL AND PREVENTIVE MEASURES. 



Tins 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.
