TRUE SCREW WORM ( Cochliomyia americana C. & P. ) 
General. F. C. BishoTo ('larch 25): Field observations indicate that the 
screw worm fly (C. americana ) was able to overwinter only as far north 
as Dixie, Gilchrist, Alachua Futnam, and Flagler Counties in north- 
eastern Florida. A few infestations of animals have occurred in counties 
along the Georgia-Florida line, indicating that there has already been some 
migration of the pest from the area where it overwintered. In Texas the 
fly overwintered only as far north as Val Verde, Kinney, Maverick, 
Uvalde, Frio, At acosa*. Wilson, Gronzales, Wharton, and Brazoria Counties. 
Spring outbreaks have been reported from Uvalde and Val Verde Counties. 
Fhenological data indicate that vegetation is advancing at Uvalde from 
about a week to 10 days earlier than normal, affording some evidence 
that trouble fron screw worms may begin earlier than usual in this 
section.
