difference in the glycogen index between the fore and hind ends of 
the larvae* The arsenicals caused marked changes in the blood 
cells.— -Yeager and Minson (705) . 
Prodenla lltura (F.), the grey-streaked moth 
In New Guinea the larvae on tobacco can be controlled witn derris 
dust.— Froggatt (204). 
Phycitidae 
Acrobasis juglandis (LeB), the pecan leaf casebearer 
A pyrethrum-rotenone spray, applied in early spring when 95 per- 
cent of the larvae nad become active, gave good control in Florida.-- 
Fhillips and Bratley ( 466 , p. 72). 
Ephestia kuehniella Zell., the Mediterranean flour moth 
In one instance the pyrethrins were 2.66 + 0.26 tiroes as toxic 
as a Derris elliptlca resin (rotenone content 37 to 40 percent) to the 
eggs.— Potter and Tattersfield (471 ). 
Etiella zinckenella (Treit.), lima bean pod borer 
Dusts and sprays containing rotenone gave inferior results, py- 
rethrum gave moderately effective results, and cryolite reduoed the 
population by over 90 percent in Puerto Rico.— Scott (633) . 
Mineola vaocinli (Riley) , the cranberry f ruitworm 
In field experiments in Washington a higher kill was obtained 
when the rotenone was in solution than in suspension. A combination 
of rotenone and pyrethrum gave better oontrol than either material 
alone. Cryolite and lead arsenate, both with oil, were each more ef- 
fective in combination with rotenone than when used alone.— Crowley 
(128 , 129). 
Good control in Massachusetts was obtained with sprays contain- 
ing 8 pounds of derris or 10 pounds of cube (both 4 percent of rote- 
none) and 2 pounds of soap in 100 gallons of water. A 2-percent rote- 
none dust with an activator and wetter, applied twice at tne rate of 
100 pounds per acre, was highly effective. A derris dust (4 percent 
of rotenone) without an activator was satisfactory at 50 pounds per 
acre. A spr?y of lead arsenate g-ave good control on experimental plots 
when applied at 400 fallons per acre, *-hough it was less effective 
than derris or cryolite. — Franklin (192, 193, 196).
