B. M, G-addis (June S*-*l4) : Hatching of M* mexicanus and M* bivittatus 
is estimated a.s 75 95 percent complete in the south-contra.1 portion 
of the State, Heaviest infestakion to date has been found in western 
Big Horn County, where populations range from 25 to 90 nymphs per square 
yard. Rather severe infestations are also present in Treasure, linieatland, 
and eastern Yellowstone Counties* Dry, v;arm v;eakher v/hich prevailed 
throughout the counties of northeastern Montana, xms favorable to 
grasshopper development. Light hatching has occurred and it is esti- 
mated thak the hatch will be complete in a week or 10 days if weather 
conditions remain favorable, M. mexicanus is the dominant species in 
northeastern Montana, comprising approximately 90 percent of the grass- 
hopper populations. In north-central Montano., moderate infestakions 
are present in Pondera and Toole Counties, while in Hill and Chouteau 
Counties they are very light and snotted,

inf esta.tions ’v':cre reported in areas in Juab, Boa.vor, Piute, Sevier, 
and Milla.rd Counties, Piold popula.tions average 25 grasshoppers per

most crop areas, with M, mexicanus , M. bivittatus , and M, packardii 
OBmprising the dominant species, in the order named. Rapid hatching 
of Camnula pellucida Scudd, occurred during the last 2 weeks in the 
meadowland areas of Sanpete County, Populations up to 5 OO nymphs

In the north-central counties of Salt Lake and Davis the miost heavily 
infested areas a,re reported on benchlands, with M, m.exicanus comprising 
SO percent of the populations* Crop injury ca.used by feeding is 
becoming noticeable throughout the infested aneas of the Sta.te* Y'oung 
corn, ba.rley, and alfalfa, crops have been severely damaged in several 
a.reas, (June S-l4); Throughout north-central Utah, M* m-exicanus is 
the dominant species. Threatening inf esta.tions are reported in several 
localities in Weber, Utah, and Morgan Counties, v/here populakions 
up to 100 per square yard are present along crop margins and on idle 
land adjacent to crops. The severely infested areas of those counties 
are, v;ith few exceptions, restricted to benchland or foothill farming
