19351. In southern Louisiana the record of 510 live weevils per ton in 
1932 is less than the number found in 1925, 1928, and 1931, but greater 
than the number found in 1926, 1927, 1929, and 1930. ‘In South Carolina 
the 1952 record of 340 live weevils per ton is less than the number 
found in 1927, 1928, and 1930, but greater than the number found in 1925, 
1926, 1929, and 1931. In Georgia the 1932 record of 845 live weevils 
per ton is the highest number for any year for which records are avail-— 
able. In Alabama the record of 147 weevils per ton in 1932 is less than 
the number found in 1927, 1929, and 1930, but greater than the number

INSECTS AFFECTING MAN AND ANIMALS 
Ectoparasites of deer in Pennsylvania.—-Harold S. Peters, Takoma 
Park, Md., spent December 5 to 7 studying the ectoparasites of deer in 
south central Pennsylvania, a continuation of a cooperative study made 
in the deer-hunting seasons of 1930 and 1931. An examination of 19 
deer yielded 34 Tricholipevrus virginianus Peters, 4 Cervophthirius 
crassicornis (Nitzsch), and 28 Dermacentor nigrolineatus Packard. Mr. 
Peters says, "It is interesting to note that only one species of biting 
louse was found, as in other parts of the State two species have been 
found. No especially heavy infestation was observed. But this informa 
tion does show us that there is a sufficient infestation of external 
parasites to cause severe damage should conditions become favorable for 
a sudden increase. The past three years' survey shows that the lice 
and ticks are found on deer throughout the main deer sections of Penn— 
Soemonie. T. virginianus has been collected in 15 counties. "This 
Species of biting louse makes up about 90 per cent of the biting lice 
on Pennsylvania deer and was undescribed until 1930." TT. parallelus 
(Osborn), another biting louse, has been found in 7 counties. "This is 
the so-called ‘common deer louse' but really makes up only about 10 per 
cent of the biting lice on Pennsylvania deer." C. crassicornis, a suck-— 
ing louse, generally rather rare on eastern deer, was found in 7 coun- 
ties. The tick D. nigrolineatus was found in 9 counties of the State. 
Goat lice yield to sulphur dips.--0. G. Babcock, Sonora, Tex., re- 
ports that "On October 7, 1932, the entire flock of Experiment Station 
goats, some 570 animals, were dipped twice in the latest and best for- 
mula. This formula consists of 10 pounds thylox sulphur dust, 25 ounces 
linseed oil soap, 25 ounces sodium phosphate tribasic, and 100 gallons 
of water. The temperature of the dip for the two dippings was 78° and 
88° F., respectively. All animals were held in the dip for a minimum 
of one-half minute and each animal was ducked at least four times. This 
insured a thorough wetting of the animal. Examinations to date cover a 
period of 75 days since dipping and have not revealed a single lousy 
goat in the flock. On October 13, in a single experiment, animals were 
dipped in 2 pounds of wettable 300-mesh sulphur, plus the linseed oil 
Soap and the sodium phosphate tribasic. Not a live louse has been found 
to date."
