Fol lowing the policy introduced last year we are issuing a sum- 
mary of the more important insect conditions throughout the United States 
and Canada during the year 1927. We are also introducing in this number 
a ne- feature in having special reviews of certain insects upon which 
special investigations are being carried on "by the Bureau of Entomology, 
and for which we have net published reports in the monthly numbers of the 
Sur v e y Bullet in s . 
GRASSHOPPERS. 
The fall survey of 192o showed enough grasshopper eggs in easter 
Montana to produce a small outbreak. In California the grasshoppers in 
the fall of 192b '-ere scarce, so egg laying v;as slight. -A decrease in 
the number of grasshoppers during the late summer of l$ J 2o --as reported 
from British Columbia. During 1927 the insects --ere distinctly below 
normal in the West-Central and East-Central States. Later in the season 
grasshoppers became numerous in central and southern Ohio. During July 
an unexpected outbreak v;as reported from the ranges of south-central 
British Columbia, a territory of 2,000 sluare miles being badly infested 
while in the peace River region the grasshoppers, which during a number of 
seasons have been a sericuc pest, were almost completely wiped out by . 
heavy rains in the spring. Some damage by grasshoppers was reported from 
southern vuebec. Late in the season (September 30) a terrific flight of 
the lesser migratory grasshopper ( Melanoplus atlan is Riley) was reported 
from nestern Kansas. 
M0RK01: CRICKET. 
The mormon cricket ( Anabrus simplex Raid.) in the fall of 1926 
was infesting practically twice the territory of the previous season in 
Montana, some 250,000 acres. An unusucl number of eggs were laid during 
the fall. Baring June of 1927 the crickets were reported as being 
more abund nt than in 1926, but control measures were very effective 
and depredations /ere slight. 
CORK EAR OP . 
During the winter and spring months ua to Lay the corn ear 
worm ( Heliothis obsoleta Fab.] was more abundant in the Fuerte Valley, 
Mexico, then it has been any season for the past four years. About the 
middle of February corn heavily infested was coming on the market at 
Brownsville, Tex. During the last week in April this insect appeared in 
injurious numbers in Louisiana :,nd central Texas. First adultsfwere ob-
