3o9 
Illinois, W. P. Flint (September 20): In the west-central and northwest- 
central parts of Illinois, and also to some extent in the southeast- 
central area j chinch bugs are developing in corn and grass in small grain 
stubble in sufficient numbers that we may expect rather serious abun- 
dance next year. 
Kansas. H. R. 3ryson (September 25): Chinch bugs may be found readily on 
sorghums at Manhattan, but are not doing any damage. 
COLORADO CORN ROOT WORM ( Diabrotica virgifera Lee.) 
Nebraska. M. H. Swenk (September 15): From Keith Count:/ on August 22 came 
the report of the Colorado corn root worm affecting corn. 
EUROPEAN CORN BORER ( Pyrausta nubilal is Hbn.)) 
Connecticut. N. Turner (September 21): Late sweet corn had 55 percent corn 
borer infested ears. About 75 percent of the ears were damaged by cither 
ear worms or corn borers. 
Virginia. H. G. Walker (September 2b): Several fields were examined about 
July 25 but no eggs were found. Pupae were reported as being rather 
abundant in the fields during the middle of August. On August 27 and 2S 
many egg messes were present, some of which had just been laid and others 
were hatching. Thirty egg masses, 13 of which had hatched, were found 
on the 30 stalks examined in one field. As many as 25 borers were found 
in 1 stalk, varying in size from newly hatched to full-grown larvae. 
This indicates very strongly that there is at least a partial third gen- 
eration. 
CORN LEAF APHID ( Aphis maidis Fitch) 
Indiana. J. J. Davis (September 23): The corn leaf aphid was again re- 
ported early in the month as being exceedingly abundant on corn, es- 
pecially on the tassels, and damaging corn in a number of localities in 
central Indiana. 
Illinois. W. P. Flint (September 20): The corn leaf aphid has been very 
abundant throughout central Illinois. At the present time it is being 
rapidly reduced by parasites. 
ALFALFA 
GEEEN CLOVER WORM ( Plathyp ena scabra Eab.) 
Kansas. H. R. Bryson (September 20): The green clever worm is very abundant 
in alfalfa fields, the population having approximated outbreak propor- 
tions in the eastern part of the State. An appreciable amount of damage 
has occurred in fields where the population is greatest.
