OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOB SEFTEMBER, 1924 
White grubs have "been reported as being more seriously prevalent than usual 
in the Ohio Elver Valley, southern Michigan, and parts of Nebraska and Kansas. 
The Hessian fly promises to be seriously abundant in Ohio, where present 
indications are that the brood will be late in emerging. Bather heavy infestation 
is also reported from Illinois, Nebraska, and Kansas. 
The European corn borer is reported as spreading southward much more rapidly 
than last year in Ohio, and the intensity of infestation has also materially in- 
creased. 
Cool, rainy weather in Kansas and Illinois is believed to be very adversely 
affecting the chinch bug and no serious damage during 1925 is anticipated in these 
States. 
The western corn roctworm is reported as moderately abundant in Michigan 
and Iov:a and seriously abundant in parts of Nebraska. 
The red spider problem has reached such serious magnitude in California as 
to be the occasion of a large conference of agri cultural advisers, growers, and 
others, directly and indirectly associated with the fruit industry of that State, 
to devise methods for control. 
The Mexican bean beetle is now reported in the northeasteromost corner of 
the. State of Ohio, thence westward, along the lake shore to Lorain County, thence 
southwestward through Hancock County and Shelby County to Butler County in the 
southwestern corner of the State. The infestation in West Virginia is now known 
to extend as far east as Harrison, Gilmer, Kanawha, Fayette and Monroe Counties, 
and in North Carolina eastward to 'Vilkes and Iredell Counties and has extended 
northward in Pennsylvania to Beaver County. In Wyoming the pest is extending 
northward in Platte County. 
The pea aphid, on the '"hole, was not seriously abundant in Wisconsin this 
year, though a slight amount of damage early in August was reported from the dried- 
pea section in Boor County. 
The cotton boll weevil on the "hole has rot been a serious factor this year 
except in a few restricted regions. About the middle of the month, however, many 
bolls were found infested in parts of North Carolina and South Carolina which had 
previously been considered safe, in many cases the damage being on well-developed 
bolls. Similar injury to well-grown bolls was reported from Georgia. Consider- 
able cotton in the Greenville district of Mississippi, the growth of which was re- 
tarded by dry weather, is now threatened by a late attack of the weevil.
