Parasitization of fall generation of Hessian fly in Kansas.——-Re— 
porting on the fall survey of Hessian fly parasites, J. R. Horton, Wich— 
ita, Kans., says that the examinations “indicated an average parasitiza— 
tion of only 2 percent for the entire (western hard wheat) region with 
Platygaster hiemalis Forbes the only parasite species present. In the 
order of intensity of parasitization, southeast Nebraska led with 16 
percent; northwest Missouri was next with 9 percent; southeast Mis— 
souri, 5 percent; northwest Kansas, 4 percent. Less than 1 percent 
of the puparia from all other State sections were parasitized, while 
those from Oklahoma had no parasitization whatever. The state averages 
were: Missouri, 2 percent; Kansas, 1 percent; Nebraska, 6 percent." 
Hessian fly parasite has numerous alternate hosts.--Mr. Hill also 
reports a list of 26 hosts of Eupelmus allynii (French), other than the 
Hessian fly, 7 of these being themselves parasites of the fly, showing 
that as to these 7 E. allynii plays the réle of hyperparasite. The hosts 
are as follows: 
Cephus cinctus Nort. Languria mozardi Lat. 
Cephus pygmaeus L, Mompha eloisella Clem. 
Eurytomacheris eragrostidis How. Neolasioptera sp. (dipterous gall) 
Harmolita atlantica Ph. & Em. Oecanthus quadripunctatus Beut. 
Harmolita elymicola Ph. & Em. Oscinid puparium 
Harmolita grandis Riley Procystiphora n. sp. 
Harmolita maculata How. Tischeria malifoliella Clem. 
Harmolita tritici Fab. Trachelus tabidus Fab. 
Harmolita vaginicola Doane
