The number of sand flies emerging from the open marshes in the spring 
show that the spray treatments. would have given a better control if they 
had been applied during the hot weather of last summer. * * * To control 
such pests by spraying would mean that it would be necessary to spray 
the areas following each of the high tides." 

Note on oviposition of yellow fever mosquito.--"In connection 
with rearing a large number of Aedes aegypti L. for motion—picture 
work," reports G. H. Bradley, Orlando, Fla,, "it was noted that the 
females laid their eggs on the water surface rather than on the sides 
of the jars above the water line. The eggs are often seen on the sides 
of the jars above the water but in my recent observations they were 
merely drawn to the side of the jar by capillary attraction and stranded 
by the receding water. About the time I noticed this J. L, Webb sent 
me an abstract of an article by Roubaud,1/ in which it is stated that 
given a free choice the female deposits her eggs above the water when 
the water is pure, but on the water when the water contains organic 
matter and microbes. After receiving this abstract I put two dishes, 
one with tap water and one with distilled water, in a breeding cage in 
which was also a jar of contaminated water. During a period of one 
week no eggs were laid on the clear waters. Upon removing the jars with 
contaminated water and replacing the jars holding tap water and distilled 
water. eggs were laid on the surface of the water in both jars, and young 
larvae subsequently appeared." 
STORED PRODUCT INSECTS 
Parasitism of the raisin moth in California.--Work by Dwight F. 
Barnes and Heber C. Donohoe at Fresno, Calif., “indicates that 241 over-— 
wintered larvae of Ephestia figuliella Greg. taken from vines in 9 vine— 
yards, from March 1 to 9, have been parasitized in the fall to the extent 
of 19.6 per cent (18.3 per cent by the ichneumonids Mesostenus gracilis 
Cress. and Nemeritis canescens Grav. and 1.3 per cent by Microbracon 
hebetor Say). An important increase in parasitism since the beginning 
of warmer weather is shown by the examinations of vines on May 11 and 25." 
i Result of a trapping experiment at Fresno.--Perez Simmons, Fresno, 
Calif., reports that "Captures of moths that infest dried fruits and 
other stored products, and of parasites, were as follows for the period 
April 12 to May 24. (The first raisin moths and specimens of Microbra— 
con hebetor Say were taken April 19.) The trapping, with malt—sirup
