PARASITES. 



Two hymenopterous parasites were reared from the larvae of 

 Etietta zinckenella scliisticolor during the investigations at Pullman, 

 Wash., viz, Pseudapanteles etiellse Vier. and Microbracon Jiyslopi Vier. 



Dr. F. H. Chittenden 1 records having reared Bracon sp. (deter- 

 mined by Viereck) from Etiella schisticolor on October 19, 1908, at 

 Santa Ana, Cal., and Mr. C. L. Marlatt 2 records rearing a braconid 

 from the larva of this moth at Nuecestown, Tex., on May 13, 1896. 



REMEDIAL AND PREVENTIVE MEASURES. 



The legume pod moth is readily controlled by preventive measures, 

 and for this reason there have been no experiments with remedies. 

 The transportation of the hibernating forms in sacks of seed, and the 

 consequent dissemination of the pest, may be prevented by fumiga- 

 tion of the seed with carbon bisulphid. 



Owing to the presence of the native lupines, extermination of the 

 pest is impossible, but by planting such early varieties of field peas as 

 come into full bloom before the last week in June it may be practically 

 eliminated as a factor to be dealt with in seed growing in the Pacific 

 Northwest. The date of planting, however, will vary in different 

 localities and under different conditions.
