late oil gave a destruction of practically all sand fly larvae ina 
small area treated in this manner. Five quarts of soil obtained from 
this area just after the treatment furnished 7 larvae. Since then we 
have been unable to recover any larvae from this area. The observa— 
tions suggest that besides the heat * * * there may be a condition re- 
sulting from the burning which also kills sand fly larvae." 
Screw—worm fly most harmful to cattle.-A study was made at Menard, 
Tex., according to E. W. Laake, to determine the species of flies attack-— 
ing livestock and to learn whether parasitism of fly larvae occurs in do- 
mestic animals. No parasite was reared from "the 11,865 larvae col- 
lected from wounds of domestic animals infested in nature. Of these 
larvae, 6,168 were fully developed and dropped normally from the host, 
while 5,967 last-instar larvae, medium to fully developed, were me- 
chanically removed from the wounds; 87.87 per cent of the former and 
66.55 per cent of the latter produced adults. The species of flies 
represented and the number of each produced were as follows: Cochli- 
omyia macellaria Fab., 9,210, or 99.82 per cent; Phormia regina Meig., 
15, or 0.16 per cent; and Sarcophaga species 2, or 0.02 rer cent. From 
a series of 10 status jars baited with meat and exposed at the same 
time and in the pens with the infested animals, more than 2,000 blow— 
fly larvae were collected. Of these 1,645 developed to adults, as 
follows: C. macellaria, 1,001; Lucilia unicolor Towns., 125; 356 Sarcoph— 
aga of four species, and 191 developed parasites, all of which were 
Brachymeria fonscolombei Duf. The pupae from which the parasites emerged 
were all of Sarcophaga. These results plainly substantiate our pre-—- 
vious contention that the screw worm fly larvae, responsible for nearly 
all cases of myiasis in domestic animals throughout the Southwest, are 
not being attacked by the parasite B. fonscolombei, either in the wounds 
of infested animals or in status jars." 
STORED PRODUCT INSECTS 
Tobacco moth in foreign trade.-W. D. Reed, Richmond, Va., states 
that * * * it is "reported that a recent shipment of tobacco to London had 
been rejected on account. of living (tobacco moth) Ephestia elutella Hbn. 
larvae in the hogsheads. This is the first shipment * * * rejected since 
our fumigation experiments last summer." . 

Tobacco beetle prefers peanut meal.—In regard to rearing stocks of 
Lasioderma serricorne Fab., Mr. Reed says: "* * * of 35 foods of the to— 
paoce beetle assembled in order to determine the best food in which to 
maintain a rearing stock protected from parasites, peanut meal appar- 
ently has the greatest attraction for the beetles, and fish meal is second 
of the foods tested," 
Moth—proofing agents and fumigants.-Wallace Colman, Silver Spring, 
Md., ‘says: "Tests with borneol, terpineol, and fenchyl alcohol as moth- 
proofing agents and as fumigants gave entirely negative results. Apparent- 
ly they have no value for use against clothes moth larvae."
