Oviposition of a tropical house mosquito.—-Reporting further on 
oviposition of Culex quingquefasciatus Say, mentioned in the December 
Monthly Letter, G. H. Bradley, Orlando, Fla., says that of 556 egg boats 
deposited, 198, or 36.6 per cent, were laid on water containing rotted soy 
beans; 184, or 33.1 per cent, on water containing soy sauce; 101, or 
18.2 per cent, on water containing hay infusion; 40, or 7.2 per cent, on 
water containing manure; and 33, or 5.9 per cent, on clear water. “The 
manure water, which has been particularly efficient in collecting eggs,” 
apparently lost its attractiveness to the ovipositing females during 
the month (December), as it showed fewer egg rafts than any of the other 
tubs, except the check." 
Blowfly parasite survey--summary.--D. C. Parman, Uvalde, Tex., 
reports that "From the jars exposed in Salinas Valley, Calif., in Sep- 
tember, the new Alysia sp. has continued to emerge to the end of the 
month (December) in considerable numbers. This parasite is indicated 
to be active at lower temperatures than any of the others we are work— 
ing with, and possibilities of its usefulness in a complex at Uvalde 
are enhanced. * * * During the last half of the year (1932) 1,008 jars 
were exposed over approximately 2,000 miles of route in Texas, Kansas, 
Oklahoma, California, Illinois, and Oregon. Of these 945 were returned 
and produced 17,877 specimens of beetles, 12,098 parasites, and 65,400 
flies to the end of the year. One new larval parasite has been found, 
the distribution of Brachymeria fonscolombei Duf. in good numbers has 
been extended over an area of more than 1,000 miles of route in four 
States, and the distribution of Psilodora and Xyalosema spp. has been 
extended considerably." 
Botfly larvae in horses, tongues decrease with advance of winter.—— 
To determine "how late in the winter, in the northern latitudes, horses 
may continue ingestion of botfly (Gastrophilus int?stinalis) larvae is—. 
Suing from the eggs carried by the host after the last of the fly activ— 
ity," E. F. Knipling, Ames, Iowa, made a count of all larvae found in 
20 tongues purchased from a disposal plant, The following counts in 
tongues examined on different dates show the waning infestation: On De- 
cember 1, 52 larvae in 5 tongues; on December 9, 31 larvae in 3 tongues; 
on December 10, 114 larvae in 2 tongues; on December 13, 63 larvae in 
5 tongues; on December 17, 23 larvae in 5 tongues; and on December 3l, 
7 larvae in 2 tongues. The stomachs and duodena of 8 of these horses 
were examined and following are the findings: 938 Gastrophilus nasalis 
L. in the duodena; 603 G. intestinalis DeG. in the stomachs; 1 G. haem— 
orrhoidalis L. in a stomach."

store-room pests and their parasites active in the field.—-Reporting

what percentage of the infestation by dried—fruit insects can be traced
