Marsh ditches harbor sand fly larvae.-——"At Savannah, Ga.," states 
W. E. Dove, "records of collections of larvae from soil samples of drain-— 
age ditches are consistent in showing that the marsh ditches are serving 
to collect and concentrate sand fly larvae, ranging from a few to as many 
as 200 per quart of soil. They are found at the edges of free water and 
in decaying leaves and soil saturated with tidal water. In some of the 
ditches only a trace of chloride is found. In others the salinity is ap- 
proximately the same as that of sea water. Collections made from soil 
covered by water do not furnish larvae. They are obtained principally 
from the wet banks of ditches and in the bottoms of ditches having wet

Piping of liquid hydrocyanic acid directly into milling equipment 
proves successful.—-George B. Wagner, Kansas City, Mo., reports that 
an interesting experiment was conducted in Minneapolis whereby liquid 
hydrocyanic acid was introduced through piping that led from a loading 
platform directly into the milling equipment, rather than into the gen- 
eral mill space. This adaptation of a method already in use for intro- 
ducing another fumigant, was an apparent success, except in elevator 
boots and flour packers, where unremoved accumulations of flour were too 
great to allow penetration when only 5 ounces of liquid hydrocyanic acid 
per each 1,000 cubic feet of mill space was used. 
Tobacco moth found in importations of Turkish tobacco.--W.D.Reed, 
Richmond, Va., who visited a number of warehouses concerned in the im— 
portation of Turkish tobaccos, comments: "Observations during August in- 
dicate that Turkish tobacco arriving in the bright tobacco belt is gen— 
erally infested by Lasioderma serricorne Fab. and Ephestia elutella Hbn." 
New food records for Ephestia Sp.--Perez Simmons, Fresno, Calif., 
reports that "Decaying apricots on the ground in a Merced County plant-— 
ing were found to be thoroughly infested with Ephestia larvae on August 
Sl. Prune 'drops' in the same area were lightly infested on August 19. 
Ripe Zante grapes (dried to make 'currants') at Orosi placed on drying 
trays August 13 and sampled the same day by Dwight F. Barnes were exam-— 
ined on August 24 and found to be infested by larvae and pupae to the 
extent of about 55,000 insects per ton+of fruity" 
Mission figs heavily infested with fig moth.—-H. C. Donohoe, of the 
Fresno laboratory, reports that the unharvested portion of the first crop 
of Mission figs collected from the ground on August 16 "were 100 per cent 
infested, the first examination showing a population of about 326,000 in-— 
sects per ton."
