the East-Central States from southern Indiana westward to Iowa and south- 
ward to ilissouri, damage being particularly prevalent in the overflow 
areas along the Missouri and Mississippi Rivers, In the area north of 
this region the corn root worm D. longieornis Say was destructively 
abundant and immediately west of this area in Colorado a new species, 
D. v i rgifer a # e £t ticked corn seriously for the first time in that State. 
IIESSIAP FLY, 
During the fall of 1926 the Hessian fly ( Ihytophaga destructor Say) 
was not appearing in threatening numbers east of Kansas, and the early 
spring situation over the Middle Atlantic and South-Central States indi- 
cated a very light infestation. In east-central Ohio there was an indi- 
cation of possible damage. 0win& to wet weather at harvest time in 1926 
much grain shattered in Ohio, Indiana, and Illinois, and as a result 
there was much volunteer wheat in that region. In the North-Central 
States the fly was extremely scarce. The situation in Kansas was a very 
general infestation with indications of a decided increase this spring. 
This condition was also prevalent in Oklahoma. Light infestations were 
also reported from the California wheat belt. During May the fly 
progressed rapidly in Kansas and the infestation was found to be heavier 
than two years ago when a very serious outbreak occurred. Despite the 
favor J Jble conditions early in the season there was but about 7 per cent 
infestation in central Illinois during Hay. During June the insect was 
reported as being negligible in Nebraska, but very serious in the 50 
south-central counties of Kansas. In general, the Hessian fly did prac- 
tically no damage to the wheat crop over the greater part of the wheat 
belt, with the exception of the very serious development in Kansas where 
a preliminary estimate showed a crop reduction of approximately 2e, 000, 000 
bushels. In the East-Central States, owing to the large quantity of 
volunteer wheat ,the fly has built up a rather threatening infestation 
for 1928. The fall survey showed practically normal conditions in 
Illinois. The summer fly surveys over the Middle Atlantic States show 
a decidedly higher infestation than has prevailed for several years over 
most of this territory. Maryland has a rather high infestation of 21 
per cent, most severe in the western part of the State. The fall survey . 
in Nebraska indie: ted but little damage by the fall brood of flies. In- 
dications are of a heavy infestation in Kansas. This insect was destruc- 
tive for the first time in Sedgwick County, Colorado, where it was infest- 
; as high as 10 per cent of the crop in some fields. 
CHINCH BUG. 
The chinch bug ( 3Iissus loucopterus Say) was generally less abund- 
ant than usual in winter quarters from central ".issouri eastward. In 
eastern Kansas and western Missouri, however, there were indications of 
chinch-bug trouble early in the season. Despite a very wet spring the in- 
sect passed miter rather successfully in Illinois, but was not present 
in sufficient numbers to occasion alann. Late in May reports of threaten- 
ing numbers of these insects were received from ilissouri and South Carolina 
The continued wet I ier of June practically put an end to chinch-bug
