TRUCK CROP INSECT INVESTIGATIONS Yn tee 
F. H. Chittenden, Entomologist in Charge 




























fo, a a recent communication from Dr. 0, F, E, Winberg, who has been acting in 
ot ge 0 the work against the sweet-potato weevil in the State of Alabama, it is 
stated that the most thorough investigations and inspections so far during the 
present harvest season have failed to show the presence of the weevil in the Grand 
Bay district, in which a small number of farms showed infestation two years ago. 
The measures adopted have been the destruction of all infested sweet potatoes, 
vhrough clean culture, hogging down the infested patches, and careful inspection 
of new plants known to be weevil free or to have been brought from weevil-free 
distric ts. The outlook accordingly is very encouraging, and it is hoped that addi- 
tional efforts in the adjoining portions of Mississippi may accomplish the sane 
benefits and that work for another season or two in Baker County, Fla., may be 
equally productive. This office awaits with interest the results of the final 
reinspections 
} F, M. Wadley, in charge of the truck-crop station at Muscatine, Iowa, has 
recently resigned in order to complete his course for an advanced degree at the 
Kansas Agricultural College. He is expected to return at the beginning of the next 
insect season and to continue the work which he has undertaken. 
J Neil F. Howard, formerly connected with this office, who recently returned 
from France, has accepted a position with the Goodyear Rubber Company at Akron, 
Ohio. 
Observations in Virginia, Maryland, and New Jersey on the Colorado potato 
beetle indicate that extensive tachinid parasitism explains the material decrease 
in numbers during the present season. In the individuals of the first generation 
more than 25 per cent appear to have been parasitized, while parasitism in the 
‘second generation is almost complete. Workers in a position to observe and trans- 
mit to this office parasitized individuals of the Colorado potato beetle will con- 
fer a favor by so doing. 
i CG. H. Popenoe will leave early in Octo 
truck-crop stations in the Central and Pacific States.
