however, egg deposition had not started. In the Big Horn Mountains 
of Sheridan County, no cricket infestations that might constitute 
a threat to crop areas have he on observed. Populations appeared to 
he light and scattered and in the few restricted areas where they 
appeared in considerable numbers they showed little tendency to 
migrate, 
Utah, G. E. Knowlton and H. 3T. Thornley (July 12 ): Moderate to heavy 
infestations are still present in the west Vernon auh Government 
Creek areas of Tooele County, Approximately 95 percent of the crickets 
are now in the adult stage and 10 to 20 percent are laying eggs, 
Idaho, B, M. Gaddis (July 6-12): Heavy migrations continued in eastern 
Idalio in Clark, Bingham, Jefferson, Eremont, and Madison Counties, 
Prom 50 to SO percent of the crickets at the lower elevations in 
the eastern part of the State were ovipositing. In southwestern 
Idaho Mormon cricket bands in the mud flats area of Owyhee County 
were still scattered; however, the crickets were beginning to bunch 
and migra.tions become rapid. Seventy percent of the crickets in 
this area were sixth- and seventh-instar nymphs and 20 percent 
were adults. In Twin Palls County adult crickets were moving into 
the higher areas, (July 13-19)* Pairly heavy migrations continued 
in Clark County, but in Jefferson, Madison, and Premont Counties, 
migrations were less extensive than during previous weeks. Crickets 
in all areas except in the higher altitudes of Clark County were 
adults and approximately SO percent were ovipositing, 
1 / 
Nevada. (June 29-July 5)* Crickets throughout most of the infested areas 
in the State we re adults; however, development, as compared with 
last season, is much later. During the 19^0 season, crickets in 
the Elko area were ovipositing by June 13, whereas this season 
copulation was not noted until about June 17* Oviposition was 
reported during the week in several areas of Pershing, Humboldt, 
Lander, and Elko Counties, Extensive migrations were occurring in 
several areas; however, in many localities crickets were still con- 
centrated in relatively small bands, (July 13-19)* Peak of migra- 
tions in the infested areas was reached during the week and oviposition 
had begun in practically all areas. In the Bullion and Jiggs areas 
in Elko County, oviposition was first noted on July l4, almost a 
month later than first noted in this area in 1940, 
Washington. B. M, Gaddis (June 29-July 5)* Peak of oviposition was passed 
in Prankliii and Yakima Counties and migrations had almost ceased 
by the close of the week, 
Oregon. (June 22-28): Two heavy migrations were in progress during the 
week in the northern part of the Warm Spring Indian Reservation. 
One band was moving northeast toward the Deschutes River and another 
was moving toward the southwest. In the area north of the Warm 
Spring River oviposition was a.bout 40 percent complete. Crickets 
were concentrating mostly on the south and southwestern slopes in 
favorable egg laying localities. In Baker County, approximately 
75 percent of the crickets had reached the adult stage and copulation 
was noted by June 25, In Gilliam County the peak of oviposition
