OUTSTANDING ENTOMOLOGICAL FEATURES OF OCTOBER ,1921 
The Hesaiati fly situation is very encouraging ir. the central 
Mississippi Valjljy Region. Very general adoption of recommendations 
as to the planting of wheat after the fly-free date is reported from 
Ohio, Illinois, Indiana, and northern Missouri, and the fly is quite 
universally reported as emerging according to schedule. 
The cetr earwonri is probably the most serious pest of the rronth, 
its outbreakrv covering the greater part of the region lying east of the 
Rocky Mounters, Miine and Massachusetts report the most serious outbreaks 
of this poa'c in years. In New England the corn earworm as a rule occurs 
only in scattering localities and is not considered a pest c The Middle 
Atlantic f^sates report the pest as extremely severe on late sweet corn 
and alj. fi^ld corn. In the Mississippi Valley very unusual depredations 
are reported from Ohio, Illinois, Indiana, Nebraaka,ani Missouri, 
The hearing before the Federal Horticultural Eoard on the 
European corn -borer quarantine was held on October 11. This hearing 
was ▼ ary well attended and is quite fully reported ir. this number. 
The chinch bug is more numerous in Ohio than it has been since 
the series of outbreaks in 1904, 1905, and 1906, It is alee^present in 
threatening numbers in Illinois and Missouri. If weatner conditions 
are favorable this win"er we may expect next year a serious infestation 
from northern Ohio, Inr iana, and Illinois, southward to the Gulf and 
oouthwestv/ard over Missouri and Kansas, to northern Texas. 
Reports of an outbreak of the sorghum web'^orr. indicate a very 
severe outbreak of this pest in the region covered by the southeastern 
corner of Kansas, the southern third of Missouri, the northwestern 
corner of Arkansas, and probably the northeastern part of *0kle.boma. In 
this region kafir corn seed in many cases is reported as an entire failure. 
An isolated report, which probably refers to this insect, has also beer- 
received from the southwestern corner of Indiana. This pest is known 
to occur eastward from the region infested this year to Maryland, and 
•southward to the Gulf. 
An outbreak of the apple and thorn skeletonizer in the lower 
Hudson River Valley developed early in the month. The irsect is 
defoliating hundreds of trees in the infested territory.
