SPREAD OF ALFALFA WEEVIL IN 1937

By J. C. Hamlin, entomologist
Bureau of Entomolojy and Plant Quarantine'
USHM States Department cf Agriculture

Because of its conflict with other seasonal activities, scouting for the
alfalfa weevil during 1937 Twas again iecessr.rily limited largely to areas
that could le visited incidentally in-connection with other research work.
The scope of this season's scouting is shown in table 1, which shows dis-
covery of previously unreported infestations in five counties, namely, Campbell,
Johnson, Sheridan, and Westcn, in northeastern Wyoming, and Custer County, in
southwestern South Dakota. Details of this scouting arc included in table 2.
A limited amount of sweoi:ing was also performed in counties heretofore found
to be infested, with the results shown in table 3.
