SCE3WWQEM ( Cochlionyia anericana C. & P.) 
United States. W. E. Dove (September 26): At present the low incidence of 
screwworm cases in the Southeastern States permits curtailment of 
control work of the Bureau in some areas and more intensive work in 
southern Georgia and Florida. From June 5 to September 18 there were 
Id, 187 reported cases of myiasis in Alabama, Florida, Georgia, Louisiana, 
Mississippi, and South Carolina, and of these 15,617 were reported from 
southern Georgia and Florida. During the 3~ weG k period ending September 
18, there were reported 3» 175 cases from Florida; 125 from Georgia; 22 
from Alabama; Uy fr^m Louisiana; 2 from Mississippi; and 8 from South 
Carolina. All of these reports include infestations of blowfly maggots 
as well as screwworms. During this period collections of larvae were 
obtained from wounds where possible, but only ones collected in the 
stockyards at New Orleans, in southern Georgia, and in Florida were identi- 
fied as C. anericana . In the Southwestern States 93,952 cases of myiasis 
were reported from June 5 to September 18 as follows: Arizona, 601; 
California, 152; New Mexico, 15, 137; Oklahoma, 666; and Texas (approxi- 
mately 75 counties) 77,396- In these States control work is well 
received by stockmen and the application of recommendations is reducing 
cases by preventing infestations. From September 1 to 18 there were 
l6,UU5 cases as follows: New Mexico, 5,225; California, 88; Arizona, 
317; Oklahoma, 266; and Texas, 10, 5%. Of these cases, 2,1^3 occurred 
in tick bites, 1,652 in navels of young, 3,193 i n snags and scratches, 
and 2,6^-0 in other causes which are not easily prevented. The incidence 
is unusually low in injuries resulting from surgical operations. In 
castrations there were 882, in dehorning 533, in marking 98, in branding 
999, and in shear cuts 3,0*10.
