OUTSTANDING ENTOMOLOGICAL FEATURES FOR JULY, 1922. 
The Hessian fly situation is very favorable over the greater part of the 
wheat Belt. Reports from Ohio, Illinois, and Indiana indicate a very decided 
reduction of this pest over last year. For the first time in 15 years this 
insect is reported from Minnesota, and the worst outbreak in the, past 4 years 
occurred in Iowa this summer. The fly is also quite serious in parts of Nebraska 
where it will in all probability seriously infest the fall grain. 
The chinbh bug has proven abundant and destructive in northwestern Ohio, 
the greater part of Indiana, southern and central Illinois, southeastern Iowa, 
qouth-central Nebraska, practically all of Missouri, and the Delta section of 
Mississippi. 
The widespread boll weevil infestation reported in the last number of the 
Survey Bulletin has decidedly increased in intensity during July. Reports of 
very heavy infestations have been received from many localities in eastern 
Texas, southeastern and central Oklahoma, central Arkansas, northern Louisiana 
and Mississippi, the greater part of^Xafr&Ja* southwestern Tennessee, and many 
places in Georgia, South Carolina, and southeastern North Carolina. 
The greater wheat-stem maggot is becoming more abundant and injurious than 
usual in the north-central States, northern Illinois, Minnesota, and North 
Dakota reporting damage this year, and considerable attention is being attracted 
by the wheat midge in southern Ohio and Indiana, where this pest seems to be on 
the increase. 
A rather unique armyworm outbreak is under way in central and southern 
California. Several »jsir$A£-*, so far undetermined, are involved in this out- 
break. The fall armyworm has appeared in rather serious numbers in parts of 
Tennessee. 
The stalk borer is more prevalent than was the case last year. Reports of 
rather serious infestations have been received from New England, New York, West 
Virginia, the east-central States, North Dakota, northeastern Nebraska, Missouri, 
and Mississippi. 
The alfalfa weevil, newly reported last year from the western part of 
Nevada near the California State line, now occurs throughout the Lovelock Valley 
in Pershing County, north of the Reno infestation. In southern and eastern 
Idaho it seems to be less abundant, possibly owing to the hymenopterous 
parasite which is on the increase in this region. In soutfchwe stern Idaho the 
wesvil is extending its range and is reported from Canyon County. 
During the latter half of June and early July reports of a root curculio 
attacking soy beans in Indiana, Missouri, and Illinois were received. At the 
time of the issue of our last Bulletin these were. believed to be Sit ona 
hispidulus Fab. (See Vol. 2, No. 4, page li5.) Specimens have since been 
received by the Bureau and determined by Dr. E. A. Schwarz as Sitona crinita 
Hbst. This is a common European species and is possibly a quite recent intro- 
duction into this country.
