HOGS 
FLEAS ( Siphonapt era ) 
VSn.Hoore (September 29): One of our men has conducted a survey 
of the State of Missouri on the relative abundance of the human 
flea in association with hogs raised in this State. Very heavy 
and serious infestation was found in the northwestern and central 
parts of the State, extending eastward to Mercer, Macon, Boone, 
and Callaway Counties and southward to Cole, Morgan, and Cass 
Counties. A mere lightly infested area extends to the eastern 
boundary of the State and southward to Jefferson, Maries, Hickory, 
and Barton Counties. The southern third of the State seems to 
be practically uninf ested. 
POULTRY 
CHICKEN' MITE ( Dermanyssus gallinae Redi ) 
L. Baseman (September 22): As the summer advanced the abundance 
of the mite seemed to decrease and few complaints were received 
during the month. 
LARGE BODY HEN LOUSE ( Mcnopon b iseriatum Piaget) 
C. Gr. Babcock (September 8): . Poultry lice have been extremely 
numerous during the last four to six weeks. In many cases birds 
were so heavily infested as to become emaciated. These birds 
revived rapidly after treatment with sodium fluoride. A pecu- 
liar feature of this infestation was that seriously infested 
birds did not show the usual paling of the wattles and comb. 
STICKIIGHT FLEA ( Echidnopha^. g ?.llin^cea Uestw. ) 
Arizona News Letter Vol. 3, No. 8 (August 31): The sticktight 
flea was found to be causing considerable concern to a dog belong- 
ing to one of the veterinarians of Phoenix. The insects had 
attached themselves to the ears and the efforts of the pup to 
remove them were far from successful. 
SAND FLEA ( Siphonapt era) 
L. Haseman (September 22): This pest for the first time has 
broken out as an epidemic on a large poultry farm in southeastern 
Missouri.
