TRUCK CROP AND STORED PRODUCT INSECT INVESTIGATIONS 
F. H. Chittenden, In Charge. 
INSECTS INJURIOUS TO TRUCK CROPS, 
Cutworms have been normally injurious during the month of May but towards 
the end of the month a number of severe outbreaks have been reported, These come 
‘ from the Gulf States and Worcester, Mass. At Vashon, Wash., Arthur J. King, Field 
_ Assistant, reports that on one truck farm where a 20-pound pail full of cutworms 
was collected on less than one-half acre of peas the cutworms which remained 
nearly ruined the crop. Injuries were reported in New Jersey and New York. The 
different species were not identified except in two cases. The greasy cutworm 
(Agrotis ypsilon Rott.) was reported injurious in New Jersey injuring cabbage, 
peas, and raspberry. Only moderate injury has thus far come to our attention in 
the District of Columbia and nearby points in Virginia and Maryland. The varie- 
gated cutworm was found in the District of Columbia, a severe outbreak occurred in 
_ Baltimore County, Md., where cutworms did great damage to tomato, cabbage, and 
“onion plants, our informant reporting that it was feared that nothing would be left.
