CHINCH BUG ( Blissus leucopterus Say) 
Ohio. T, H, Parks (June 25): Chinch hugs were difficult to find in most 
fields in central and western Ohio, hut a few adults and first- and 
second-instar nymphs were observed this week in wheat at Van Wert 
and Columhus, No serious damage is expected. 
Indiana. C. Benton (June Ij): Except for a slight drop from a general 
average of 9 to 7 foot of drill row, in La Payette, the adult popu- 
lation in winter wheat remains similar to the last 2 weeks, although 
the general stand of wheat and weedy undergrovrth has become more rank 
during this period, Pirst-hrood nymphs were showing rapid increase. 
Many of the heavily infested thin .spots in w^heat show an average of 25 
or more, and in spots even 50 or more, nymphs per foot of drill row. 
Over 95 percent of these are first-instar nymphs. Pirst-instar nyn^hs 
were first observed on June l4, and a few third-instar nymphs were 
found today. Many adults are moving to adjacent corn, as high as 12 
or more being found per hill of corn. Oats in this locality still 
show a trace of infestation. 
J. J, Davis (June 22): Bugs overwintered in threatening numbers; 
however, rank growth of wheat, resulting in dense shale,, has been 
unfavorable and many of the adults left the dense wheat to go over 
to corn, where they have laid eggs and where first-instar nymphs occur. 
Illinois. W. P, Flint (June I 9 ): Heavy rains during May have considerably 
reduced the popule^tion all over the State. There are still some spotted 
fields where damage may occur. It is estimated that the population has 
been reduced from about 60 to 75 percent. Owing to frequent rains, 
many bugs left wheat and went into corn when it first came up. In most 
instances the corn had sufficient moisture to outgrow any damage, 
Iowa. H. E. Jaques (June): Abundant in the southern counties of the State. 
Nebraska, H. D. Tate (June 18); Inquiries concerning methods of controlling 
chinch bugs were received during the period May 3 I to June 15 from 
Richardson, Otoe, and Cass Counties. A report on June l4 indicated 
that newly hatched bugs were destroying corn in Cass County. 
Kansas, H. R. Bryson (June 25): More abundant and causing injury over a 
much larger area than last year. Barley fields, and fields where chess 
or cheat occurs, are heavily infested. Reported as migrating into corn 
and sorghums from pastures in which little barley is prevalent. Winter 
wheat closely pastured late this spring furnished a considerable migra- 
tion into adjoining cultivated crops. Very few of first generation 
nymphs have reached the adult stage, . First adult observed at Manhattan
