HESSIAN FLY ( PhytQT>haga destructor Say) 
S. C. Chandler (June 14): The Hessian fly is moderately 
to very abundant in southern Illinois. 
H. E. Jaques (June 26): The Hessian fly is moderately 
abundant in the southern half of the State. 
L. Haseman (June 23): The Hessian fly is moderately 
abundant. The spring brood has not bred so abundantly 
as was expected, owing perhaps to the cold spring. 
M. H. Swenk (June 13): A very serious outbreak developed 
in 'southeastern Nebraska during the period May 15-June 15, 
but that outbreak is not being reported on at this time since 
a special investigation is still in progress. A report on 
this outbreak will be made early in July. 
WHEAT STRAW WORM ( Harmolita grandis Riley) 
F. L. Thomas .(June 25): The wheat straw worm is abundant 
in Ochiltree and Gray Counties. 
T. R. Chamberlin (May): The first adults were swept in 
Linn County May 9, and they were common in sweepings in 
Clackamas Couut.y by May 22. 
WHEAT JOINT WORM ( Harmo Vfta tritici Fitch) 
T. R. Chamberlin (May): Cool, rainy weather has so retarded 
issuance from theetubble that by May 22, 35 days after the 
first issuance, only one-half of the adults had emerged. In 
1929 the first adults issued May 15 and one-half had issued 
by June 3, 19 days after the first issuance. Adults have not 
been swept abundantly from growing wheat at any time during 
the spring of 1930. 
STEM MAGGOTS (Merpmyza spp.) 
T. R. Chamberlin (May): Sweepings in the "allamctte 
Valley during April and May indicate that M. nigriventris Macq. 
is less abundant than usual throughout the valley and in some 
sections (Linn County) much less abundant. This condition 
is probably the result of the very dry fall of 1929, with little 
volunteer grain and fresh grass for the flies to oviposit upon 
and higher mortality among the flies before they wore ready for 
oviposition. M. flavipalpis Mai loch was scarce in sweepings 
during April and May.
