Prof. A. F. Conradi, State Entomologist of South Carolina, and a dele= = 
gation from his State visited the peach insect laboratory at Fort Valley, 
Ga., on May 20, to observe investigations under way. 
EH. J. Newcomer, in charge of the Yakima,.Wash.,. Station, writes: "There 
was a very decided increase in the amount of oil used as a dormant spray in 
the Yakima Valley this svring. In 19243 not over 200 barrels were used. In 
1924 there have been about 10 carloads of lubricating oil and 4 carloads of 
prepared oil sprays used, equaling about 1,200 barrels of stock spray. This 
vould be enougn to spray about one-tenth of the trees in the valley. In 
spite of this, lime-sulphur manufacturers report the sale of more lime-— . 
sulphur than last year. Of the oils used, probably as much cold-mixed casein- 
oil emulsion was used as anything, the growers making it themselves with 
power spray outfits." 
Dr. B. A. Porter, in charge of apple insect investigations at Vincennes, 
Ind,, states: "Orchard men in scuthern Indiana continue to report good control 
of the San Jose scale with the lubricating-oil emulsion. Counts made recently 
in two commercial orchards showed 0.7 per cent of live scale in one, and 0,1 
per cent in the second. 
NTwo interesting points were brought out by an investigation into a 
serious injury to peach trees in southern Indiana, which for a time was 
attributed to the use of paradichlorobenzene for the control of the peach 
tree borer, but was soon shovm conclusively to be due to winter injury. The 
first point was the extent to which this chemical treatment has been adopted 
by the growers... It was impossible to find a commercial orchard of any size 
vhich had not been so treated. The second point was the almost total absence 
of borers from the treated orchards, most of thich have now had three annual 
treatments. In the best orchards less than one per cent of the trees examined 
showed any sign of recent borer infestation, while untreated trees in this 
section are absolutely infested." 
Basil E. Montgomery of Poseyville, Ind., is assisting during the summer 
in the work of the station at Vincennes. Mr. Montgomery is a graduate of 
Oakland City College, and is planning to take graduate work in entomology 
at Purdue this fall, 
H. K. Plank, in charge of the camphor scale project at New Orleans, 
and i. D. Whitcomb visited some Satsuma orange groves near Mobile, Ala., 
on May 6 and 9, with a view of inaugurating spraying experiments in the cone 
trol of the camphor scale. In one grove, reported to be a fair average of

the southern Alabama orange district, about 75 per cent of the trees were entirely 
killed by the freeze of lest January, when the temperature went to about 1° F, 
Two small Satsuma groves near Gulfport, Miss., were almost entirely wiped out 
by this freeze, and in one large grove near Lyman, Miss., in perhaps better 
growth condition, about 30 per cent of the trees were killed. Few if any of the 
Satsuma trees which survive will produce fruit this season,
