flights "being in a somewhat northerly direction, A large field of corn 
in the southern part of Marshall County reported as infested with bugs 
which had settled there during the spring flight. Population averaged 
from 10 to 12 per cornstalk, (May 23)* Surveys made during the last 
2 days in Clarke, Polk, and Warren Counties, Infestation in small 
grain ranged from 2 to 4 b\igs per square foot to as high as. 25 or 30 
in many oat- and barleyfields. Wheat generally more heavily infested, 
and counts ran from 15 to 75 or 100 per linear foot of grain in drill 
row. In some fields in the southern parts of Polk and Warren Counties, 
the population ran as high as 100 per stool of wheat. In 1 field in 
southwestern Warren County S percent of the barley had been destroyed 
by adults. Population in this field averaged between 15 and 20 bugs 
per plant, A number of oatfields in this part of the county showed 
damage of from 1 to 3 percent. Egg laying has just started. Migration 
not quite complete. Situation apparently very serious throughout a 
large part of southern Iowa, especially the southwestern part, 
Missouri, L, Haseman (May 21); Bugs apparently have not all reached small 
grains throughout central and northern Missouri, as infested fields are 
rather spotted. In central Missouri oviposition has begun but apparently 
no eggs have hatched. The recent rainy spell was ,favora"ble to crops 
and held back bug activity, . , 
Nebraska, M, H, Swenk (May Ij); Inquiries as to the situation received 
‘late in April and early in May from Richardson to Douglas Counties, 
in southeastern Nebraska, A survey in May showed a heavy population in 
the small-grain fields in this area, 
Kansas, H, B, Hungerford (May 20): Bugs have come out of winter quarters 
in considerable numbers in the vicinity of Lawrence, 
Oklahoma, C. P. Stiles (April 30)* A survey conducted last week through- 
out Tulsa, Wagoner, Mayes, Muskogee, Okfuskee, and Noble Counties, 
showed that the number of bugs per linear foot of drill row ranged 
from 0 in all land planted to oats. to around 3P ^ fields of 
barley. Infestation heaviest in Muskogee and Okfuskee Counties, 
(May 22): Infestation throughout the State seems to be very spotted, 
and many fields of barley are seriously infested, whereas nearby fields 
of wheat and oats are practically free. Control measures necessary 
to prevent damage to corn and grain sorghums, 
P, A. Penton (May 24); Pirst generation of nymphs is now developing 
in small grains, but the bugs have not started moving into, cornfields,

wheat plots at the Carlisle laboratory.
