GRAPE LEAFHOPPER ( Erythroneura comes Say) 
Nebraska. I/I. H. Streak (September 15): A Merrick Comity correspondent re- 
ported his grapevines being infested with the grape leafhopper on 
August 27 and a Dawson Count" correspondent made a similar complai 
regarding his woodbine vines on September ]h. 
Utah. G. F. Knowlton (September IS): Grape leafhoppers are seriously 
damaging grape and Virginia creeper foliage. 
California. 3. L. Fox (September 5): She grape leafhopper is doing a 
moderate amount' of injury to grapevines locally , but the injur- is not 
sufficient to warrant control measures this late in the season. 
GRAPE 3ERRY MOTH ( Polychrosis viteana Clem. ) 
Ohio. T. H, Parks (September 28): Infestation varies greatly in the com- 
mercial vineyards along Lake Erie. Last week I found one vineyard with 
fully ''-0 percent of the grapes ruined, while others in the same general 
neighborhood were not seriously infested. Accurate counts made in one 
vineyard that had received two sprays showed that from 12 to lS percent 
of the berries were infested. 
PEC A." 
PALL WEBWORM ( Hyphantria cunea Drury) 
Georgia. 0. I. Snapp (September 0): The fall webworm is more abundant 
than usual at Port Valley. There are many nests in pecan trees and the 
larvae have eaten many leaves on some trees. 
Mississippi. C. Lyle and assistants (September 23): The second generation 
of the fall webworm is rather generally distributed over Mississippi, 
although the infestations are not nearly as heavy as in some years. No 
very extensive defoliat ion of pecans and persimmons has' occurred.

of the month there was an infestation of the walnut caterpillar. Heavy 
defoliation of pecan trees resulted.

Experiment, which is about normal and 2 weeks earlier than in IS" • 
Emergence was at a peak August IS. The total damage promises to be Ion 
this year 1 though the short crop of Stuarts will probably be well infested,
