The accm:-an"in- na- is based on eprly winter surveys of the area
infested by chinch bu:s in 1975 and adjacent areas, conducted by the State
entonolojists of Michigan, Ohio, Indiana, Illinois, Tisconsin, "'innesota,
Iota, Missouri, Yebrasha, Kansas, end -O':_laho.u?, either ii coner-tion vith
the 2ure.eau of Ento-ioloc-" and Plant Quarantine or entirely on State .uJnos.
These surveys vere supplenented by re-oorts froi State and federal entonolo-
gists. 'ost of the surveys -ere based oni hibernating bu-s. So'ie ox the
infor-nation, however, vas based on the in:'estation in stan6din.s corn late in
the season. In vie*; of the varied conditions and ties o:-. covr-r in ciff'er-
ent regions and unavoidable differences in survey methods the degrees of
severity indicated on the ma-o are only ap-roxi-tate.

Hibernmting -tonulations in general are considerably lighter than
they vere a year ago and the area, in which chinch bujo.s aere -,resent in
dangerous numbers is considerably less. Xr-' eiitery reports rn-] Iov:a,
Illinois, and Indiana also indicate a winter mortality of about 50 percent
over a rather extended area. The -orosoect of severe and v'ides-rread injury
in 1936 is, therefore, decidedly less threatening than in 1935. At the
sa-ne time, the bugs are still so numerous that s-ootted injurious infesta-
tions in several States, with rather severe and generall infestation in the
hert of the Corn Belt, mnay occur if s-'ring and early sumn-er weather condi-
tions are favorable to chinch bug activity.
