Illinois. W. P. Flint (May 17). "Normal outbreaks occur over the entire State. 
The v/eather for the past month has been very favorable to Hessian fly 
development. The insects are now about half in the larval stage and 
half in the flaxseed stage." 
Missouri. A. F. Satterthwait (March 28). "Hessian fly eggs had become very 
numerous on the laboratory wheat between March 22 and March 26." 
(March 28). "At Webster Groves brown puparia are now frequently 
found." 
H. C. Hensley (April 30). "The Hessian fly is much more abundant 
than usual. Present indications are that 15 per cent of the crop 
has been damaged in New Madrid County." 
Leonard Haseman (May 15). "We will probably have the worst out- 
break we have had since 1916. The fly is now mostly in the flax- 
seed stage. One sampife sent to the Station showed 98 per cent in- 
festation with an average of 9 larvae or flaxseeds to the infested 
tiller." 
Dr. Haseman included with his report a map showing the general in- 
festation of this insect as covering most of the State, with the ex- 
ception of an area in the south-central part extending from Taney 
County on the southwest, Butler County on the southeast, Washington 
County on the northeast, and Camden County on the northwest. 
Oregon. M. M. Reeher and L. P. Rockwocd. Tulletin and Willamette Valley. 
"The outbreak is about average for the first spring brood, being 
about 25 per cent less than last year. The first spring flight 
was completed by May 1 at For est. Grove. About 36 per cent of the 
plants and 26 per cent of the tillers were infested, while at McMin- 
ville 48 per cent of the plants and 30 per cent of the tillers were 
infested. The area at McMinville was mostly winter vheat followi ng 
spring and showed a high percentage of infestation for late som 
winter wheat. Two fields at Forest Gi ove seeded in September during 
the fall flight of the Hessian fly had 73 per cent of the plants and 
59.5 per cent of the plants, respectively, infested by the first 
spring brood. These fields were thinned to from 50 to 70 per cent 
of a stand last fall by the fall brood of the flies." 
STRAW-WORM (Harmolita ^rande Riley . ) 
Missouri. A. F. Satterthwait (April 28). "The straw-worm is now in the pupal 
stage, at least in part , according to observations of April 25." 
JOINTWORM ( Harmolita tritici Fitch. ) 
Illinois. W. P. Flint (May 17). "This insect is more abundant than usual in 
the central part of the State; oviposit ion has taken place in the 
central and southern parts of the State during the past week."
