sulphate with lime-sulphur undoubtedly results in the formation of iron 
sulphide. The trees sprayed with it have the appearance of being dipped 
in ink; but after a day or so all the black color disappears because 
the iron sulphide has changed to iron oxide. Even where the chemical 
analysis showed that there was little or no sulphur left on the trees, 
the rust mites did not come back as they did on trees sprayed with lime- 
sulphur solution alone. No injury occurred to the trees and no signifi- 
cant changes in the composition of the fruit have been detected, 
Fruit moth parasite record from Japan.--G. J. Haeussler, who is en- 
gaged in obtaining parasites of the oriental fruit moth in Japan, sum- 
marizes last season's records of the parasitization of twig-infested lar- 
vae. He has found the greatest percentage of parasitization in Chosen, 
the next greatest in the southern islands of Kyushu and Shikoku, and the 
least in Hondo, the central island of Japan. The data obtained are as 
follows:

Bait trapping of the oriental fruit moth.--The three outstanding 
baits used in large-scale bait-trapping of the oriental fruit moth at 
Cornelia, Ga., in 1932, according to W. P. Yetter, jr’, and L. F. Stei- 
ner, were: "Oil of anise 1/4cc per trap in 10 rer cent No, 3remelt sugar; 
ethyl cinnamate 1/8 cc per trap in 10 per cent No. 3 remelt sugar; 
terpenyl acetate 1/2 cc per trap in 10 per cent medium soft sugar. The 
oil of anise bait averaged 50.1 moths per trap during the season; the 
ethyl cinnamate averaged 37.6 moths; and the terpenyl acetate, 55.0 moths. 
Check No. 1 averaged 27.4 moths per trap during the season and Check No. 
2, 20.4 moths. At 1932 prices of aromatics, sugar, and saponin the oil 
of anise bait cost $2.67 per 100 gallons, the ethyl cinnamate, $2.76, 
and the terpenyl acetate, $3.26. The 2,200 experimental traps caught 
37,614 moths in 1932, whereas 2,400 traps in this same area in 1931 
caught approximately 18,500." 
Paradichlorobenzene dissolved in kerosene or in gasoline injuri- 
ous to peach t ees.--Oliver I. Snapp and J. R. Thomsen, of the Fort Val- 
ley, Ga., laboratory, report experiments in which peach trees infested 
with the lesser reach borer (Aegeria pictipes G. and R.) were painted 
with paradichlorobenzene dissolved in kerosene, and other trees were 
painted with the same chemical dissolved in gasoline. While a complete 
kill of borers resulted, many of the trees were severely injured. In the 
same series of experiments emulsified asphalt was applied. This material 
proved to be valueless in borer control.
