Empoasca fsbae (Harr.), the potato leafhopper 
In tests against the Mexican bean beetle on lima beans, the 
following was recommended if this leafhopper was also present: 4 
pounds of djrris, cube, or timbo (5 percent or rotenone) in 100 
gallons of spray, or 40 pounds of dust with the addition of sulfur 
or a copper compound.— Euolcett (299) ■ 
Derris-talc dust was not consistent in its reduction of leaf- 
hopper populations; damage was relatively high, but the yield was 
also high.— Manis and Leffert (390 ) . 
In laboratory tests with bordeaux mixture and aqueous suspen- 
sions of pyrethrum and derris, only the pyrethrum had an appreciable 
toxicity as a contact poison on adult potato leafhoppers.--.Vatkins 
(654). 
Rotenone did not repel this leafhopper on citrus.— VToglum and 
Lewis ( 698) . 
Brnpoasca filament a DeL. 
A pyrethrum-cube-talc dust was effective in controlling this 
leafhopper on potatoes, but a cube-talc dust did not control it. 
The former consisted of 5 pounds of Dry Pyrocide (2 percent of py- 
rethrins) and 95 pounds of cube-talc dust containing 1 percent of 
rotenone. The latter also contained 1 percent of rotenone by 
weight.— Manis and Turner (391). 
Etapoasoa maligna (Walsh), the apple leafhopper 
In an orchard which had been treated yearly for 4 years wi-th 
0.5-percent rotenone dusts, leafhoppers did not develop, possibly 
because of the killing action of the rotenone on the adults.— Garman 
(222). 
Bnpoasca Typhlocyba rosae (L.), a rose leafhopper 
Dust roses with copper-rot en one dust.— Mc Daniel ( 379 ) . 
Bnpoasoa terra e-reginae Paoli 
In Queensland some control of this species on cotton was given 
by nicotine dusts and by two proprietary dusts containing 3.2 per- 
cent of "tubatoxins as derris," but the frequent applications that 
would be neoessai*y malce their use economically impracticable.— 
Sloan (545).
