The Hessian fly surveys in the principal wheat-producing States of the 
Mississippi Valley are rapidly being completed. The survey in Ohio indicates 
an infestation of 17 per cent of the straws. The Bureau of Crop Estimates 
reports a crop for this State of over 24,000,000 bushels, valued, July 1, 
at over 441,600,000. The Missouri Hessian fly survey is about one-half com- 
pleted. The reports so far received indicate an average infestation of 21 
per cent of the straws. The fly is also present in such numbers as to be 
a serious menace to this fall's sowings in Indiana and Nebraska. Parasit- 
ism runs so high in Ohio as to indicate a very small fall brood emerging. 
Illinois, Kansas, and Oregon report the fly situation as very encouraging. 
The greater wheat stem maggot outbreak, reported in the last number of 
the Survey Eulletin, has developed even more seriously than anticipated; a 
survey of the situation in two counties in Oregon showed nearly $1, 000, 000 
damage and the unsurveyed territory is many times this area. Another ser- 
ious outbreak of this insect is reported from. Nebraska. 
The pale western cutworm outbreak, reported in the la3t number, has ter- 
minated, the larvae having gone into aestivation. Heavy flights of the western 
army cutworm moths are eported from Minnesota, Ioiva, and Lion tana. 
The jcintworm is a very serious pest in Green County, Mo., having destroyed 
from 10 to 16 per cent of the straws, and the western wheat sawfly is reported 
as being numerous in northern North Dakota, the wheat having already started to 
lodge on account of this infestation. 
The chinch bug is now reported as seriously infesting corn in Indiana, Il- 
linois, and Missouri. The first serious outbreak in many years is reported 
from South Dakota and Mississippi. The damage has about ceased in Nebraska 
and is not serious in Kansas and Ohio. 
The corn earworm is appearing in destructive numbers in Illinois, Kansas, 
and Florida, and a bad outbreak of the seed-corn beetle is reported from 
southeastern Nebraska. 
Grasshopper outbreaks in the upper Mississippi Valley are reported as 
being under control in Minnesota, North Dakota, and northeastern 7/isconsin. 
The poisoned bran method of control is being used throughput this region. 
Outbreaks are also reported from Missouri and the north-central part of 
New York State, wliile the most serious general outbreak in years is repor- 
ted from Montana. 
Much damage is being done by wireworms in the northern part of New York 
and in parts of Illinois, North Dakota, Kentucky, and Missouri. 
The clover and alfalfa seed crop is threatened in several important 
seed-producing regions- An unusual amount of damage is being occasioned 
this year in Arizona by the clover gall midge infesting Peruvian alfalfa. 
The alfalfa seed crop in Montana is again infested by thripsj last year 
this insect destroyed the entire crop in seme localities in this State. 
Reports from Oregon indicate that the clover seed midge lias entered the 
ground in large numbers and a bad outbreak is anticipated.
