lonnecticut w. E. Britton (August 2k): The stalk borer has "beer, reported from 
Trumbull, Hand en, Higganum, Salem, South Britain, North Haven, and 
Pamfret. It attacks dahlias as well as corn. 
..e-.7 York p. J. Chapman (July 25) : Prom the number of specimens sent in and 
from observations made in various parts of the State, the common 
stalk borer appears to be much more common and injurious this sea- 
son than last. It has been reported attacking numerous kinds of 
plants. 
.Indiana J. J. Davis (July 30) : The stalk borer continues as a common pest 
The specimens now being received are noticeably larger and lack 
the conspicuous stripes of the younger larvae. Reports since July 
20 have come from Fierceton, Ft. ~ayne, Hartsville, Richmond, La 
Fayette, Boswell, Amboy, Logan sport, and Liberty. While most of 
the reports indicate corn as the host, a fey reports relate to to- 
mato, beans, and hollyhock, etc.

In several sections of the State, particularly the northcentral 
part, the insect is certainly considerably more abundant than usual 
Examinations of the marginal rows of cornfields in central Illinois 
show a damage of from 2 to 20 per cent caused by this insect. In 
most cases only a small fraction of one per cent of the corn is in- 
jured in the center of the field. In some cases, however, where 
fields vrere ^uite grassy and weedy in the fall of 192o, danage by 
this insect would be found all over the field. The larvae are ap- 
proaching maturity in the southern part of the State. (August IS): 
Specimens of this insect are still being received in considerable 
numbers, and from a very wide variety of plants. The larvae are 
practically full-grown at the present time, but no papae have been 
found to date. 
South H. C. Severin (August 8): TOiile the common stalk borer -.-as probab] 
Dakota unusually abundant this year, many of our inquiries are due to pub- 
licity of the European corn borer.
