killing fields of rice^ before they could be flooded. As you 
may know, both the seasons of I92U and 1925 were exceptionally 
dry and this factor was probably responsible 'for the unusual 
abundance of chinch bugs. 
South Dakota H. C, Severin: The chinch bug was quite a serious pest with 
us a few years ago, but has' become a negligible factor during 
the past two years. 
Nebraska M. H„ Swenk: As previously reported, the chinch bug went, 
into hibernation in increased numbers the last fall over a large 
territory, but we are hoping that the character of the present 
winter will partly offset that advantage to the bugs by inducing 
an increased mortality. 
Kansas J, W, McColloch: Chinch bug conditions in Kansas are still 
serious. Large numbers of crops are to be^found in the clump- 
forming grasses throughout most of the eastern half of the 
State. In' addition to. the bugs hibernating in the grass, there 
are' an exceptionally large number in the com and sorghum 
fields. This is undoubtedly due to the fact that the low 
temperatures of October caught many bugs before they had time to 
migrate to the grrssland. Thus far the mortality in the corn 
and sorghum stalks has been comparatively low. 
In aonnection with the studies or. Sudan grass stubble as 
hibernating quarters for the chinch bug, exceptionally large 
numbers have been found this year. Here, again, the mortality 
is low. Many counties have pushed the burning campaign, and 
in many areas all roadsides and waste areas have been burned. 
GR^EN BUG- ( Toxoptera graminum Rond. ) 
Kentucky H„ Garman: The green bug has been giving considerable trouble 
recently on bluegrass in early spring. I found last season brown 
patches of the grass where it was especially common, and am 
looking for it again this season. I did not find, it on the 
bluegrass in the fall and assume that it hibernates on wheat 
or ether small grains and comes to the bluegrass only in early 
spring. 
Wisconsin C* L. Flute: This aphid is becoming more numerous each year 
and this past summer it was quite common throughout the southern 
and eastern parts of the State and was considerably more numerous 
thanit was last year. 
Missouri L. Kaseman: Have observed none and have hr.a no complaints about 
it this fall and winter. 
Texas F. L„ Thomas: Mr. G-able has sent this office information ~ith 
reference to green bug infestation which he investigated in a 
field near Sherman, Tex. This was a small infestation and was 
the only one which he could locate in that territory as a result
