A field survey of the Hessian fly was made by the staff of the Wich— 
ita, Kans., laboratory in the States of Kansas, Missouri, Nebraska, and 
Oklahoma, and in the southern part of Iowa. Four men took part in the 
survey and the traveling was done by automobile at very reasonable ex-— 
pense. In its course 295 fields were examined in 134 counties. A para— 
site survey was made which started June 1 and covered west central and 
northeastern Missouri, south central Iowa, and northeastern Kansas. The 
distance traveled was 1,590 miles, and during the survey 55 examinations 
were made and material collected expressly for parasite work. More than 
half the month of June was spent in connection with experiments to deter— 
mine the correct time of sowing wheat to avoid damage by the fly. 
An outbreak of the Mormon cricket has been reported in Franklin 
County, Wash. The crickets had damaged a strip from 8 to 10 feet wide 
along the north side of a winter wheat field. Most of the crickets were 
in the grasslands, especially where sage brush occurred, above 1,000 feet. 
The wheat will be harvested with combines as soon as the weather permits 
and no further damage is expected this year. 
The serious grasshopper outbreak in South Dakota and Nebraska re— 
quired the major attention of the Bozeman, Mont., field laboratory dur- 
ing June. Melanoplus differentialis Thos. and M. bivittatus Say are 
the dominant species, with a mixture of less abundant species. After 
a request for help from Senator Norbeck and Representative Williams of 
South Dakota, R. L. Shotwell and Fred Morton, of the Bozeman laboratory, 
went into the infested area and cooperated with A. L. Ford, Extension 
Entomologist, in meeting the situation. Field tests were conducted to 
try out the various baits being used and to determine the best time to 
scatter baits. Valuable data were also obtained on migrations, food 
preference of grasshoppers, and cost of control operations. The work of 
Messrs. Shotwell and Morton was highly praised by the State and county 
authorities. A single instance of saving was the discovery by Mr. Shot- 
well that a commercial grasshopper bait which was being used .in carload 
lots contained too low an arsenic content. Had the material been put 
out as planned, the poor results would very likely have wrecked the entire 
campaign. 
At the request of A. L. Strand, State Entomologist for Montana, 
J. R. Parker, of the Bozeman, Mont., laboratory, accompanied him on a 
survey of grasshopper conditions in western Montana in June. Armies of 
"warrior grasshoppers," Carnula pellucida Scudd., were found doing damage 
in Lake and Flathead Counties and the county agents in these counties were 
aided in starting control campaigns. At Lakeview, Mont., the first hatch— 
At the request of the Washington office C. R. Ainslie, Collabora— 
tor, visited the grasshopper-infested areas of northern Nebraska the 
latter part of June and first week in July. He rendered valuable as— 
sistance to the county and State workers in the organization of control 
campaigns. Although Mr. Ainslie is in retirement status he retains an 
active interest in entomological work.
