THREE-CORNERED ALFALFA HOPPER ( St i ctoceohaia f estina Say) 
Utah I.'lf. Hawley (June 14): Tre.? hoppers are serious in young orchards 
and twigs of older trees where alfalfa or sweet clover is abundant'. 
A dormant spray of miscible oil was effective in killing eggs. 
SAN JOSE SCALE ( Anpidiotus perniciosus Coirs t.) 
New York G. E. Smith (July 15): The San Jose scale is plentiful on fruit in 
neglected orchards in Orleans County. 
Indiana B. A. Porter (June 2): At Vincennes the first crawling young were 
observed. (June 2l): Firs x-gene rat ion crawling young are present 
in large numbers. Where careless spraying was done, or where the 
dormant applications were omitted, the fruit is already badly spotted 
J. J. Davis (July 16): The San Jose scale continues as one of the 
biggest problems of the fruit grower. However, good control was 
obtained by the new lubricating- oil emulsion, applied during the 
dormant season, and satisfactory results are also being obtained 
with the summer applications of this emulsion, 
Missouri L. Haseman (July): This pest has met a new check, lubricating- 
oil emulsion. Many Missouri grower.? used it in place of the lime- 
sulphur during the last dormant season. Generally good results are 
reported, but, like lime- sulphur, the spray kills only those actually 
hit by it. This pest also is behind its normal schedule, which will 
probably result in one less brood this year. 
New Mexico R. Middlebrcok (July): The San Jose scale is reported attacking 
fruit throughout this State, but pretty well controlled by spraying. 
Washington E. J. Newcomer (June 23): Late applications of lime-sulphur do not 
appear to have been very effective this year. A period of warm 
weather from April 15 to 17 apparently started the scales growing, 
and they were largely able to overcome the effects of the spray 
applied aoout this time or later. In one case 16 per cent of the 
scale remained alive, and in another 3 2 per cent were alive, although 
the latter orchard was very thoroughly sprayed. Lubricating- oil 
emulsion killed S9 per cent at this same time. 
OY3T£R->3KELL' SCALE ( Lepid os aphes ulmi L.) 
New York R» E. Horsey (June 27): This insect was found on lilacs at Highland 
Park, but not numerous. Young were moving June 18 for the first 
time this year. Less than usual are to be found. 
G. E. Smith (July 15): This scale is abundant in Orleans County in 
neglected orchards. 
Indiana J. J, Davis (July 16): The oyster-shell scale continues as a big 
problem in the State. It is particularly destructive to lilac, 
cornus , and ash. Recently we observed it doing noticeable damage 
to walnut shade trees at Portland, and incrusted rose twigs were 
received recently from Veedersburg. Tests with summer sprays 
applied 10 days to two weeks after hatching gave good control.
