nae eats 
and no subsequent sign of injury developing, no matter what oil was used 
or what the condition of the trees or the orchard in which they were 
growing; (2) 5 percent lubricating oil emulsions caused no serious 
injury but did retard bud opening and development in some instances, 
with the result that the foliage on some of these trees was weak and 
Sickly, some trees developing in a normal manner and others dying back 
to leave dead limbs (mostly small ones); (3) 6 percent lubricating oil 
emulsions caused some injury to almost every tree, sometimes very Livia 
and sometimes serious. The foregoing data substantiate the results of 
Similar tests reported in previous years and bear out the recommenda— 
tions already made concerning the use of lubricating oil emulsions on 
pecan trees during the dormant season. They further indicate that the 
lighter, more volatile oils are somewhat safer than the heavier, less 
volatile ones but that the added margin of safety is small." 
Successful shipment of oriental fruit moth parasites to Japan.— 
H. W. Allen, Moorestown, N. J., reports that "The first shipment of par-— 
asites to Japan was started on May 3, by air express to San Francisco. 
It consisted of 5,400 adult Glypta rufiscutellaris Cress. obtained from 
overwintering ragweed borer. Although 2 days were allowed for delays 
in air transit to the Coast, the consignment encountered unusual transit 
conditions and missed the boat. It was held over at San Francisco for 
about a week until the next boat, and, although it arrived in Japan over 
20 days (May 25) after leaving Moorestown, we have received a report 
from G. J. Haeussler that the parasites arrived in very good condition." 
Results with chemically treated codling moth bands.—-M. A. Yothers, 
Wenatchee, Wash. , reports that "Properly prepared corrugated paper bands 
killed from 98 to 99.67 percent of all larvae entering them. The addi- 
tion of aluminum stearate or alpha naphthylamine to beta naphthol and 
oil apparently did not increase the kill. il of 3500 seconds Saybolt 
viscosity showed no advantage over 100-seconds oil in so far as percent— 
age of kill was concerned. Commercially treated crepe paper bands (beta 
naphthol and oil) caught only from 1/4 to 1/2 as many larvae as were 
caught in nearby Corrugated bands. Commercially treated beta naphthol 
bands with a 1/4 inch flange at each side of the back were effective in 
killing 99.5 percent of the larvae entering them, but the presence of the 
flange showed no advantage whatever and bands having it actually aver— 
aged fewer larvae captured than did the bands without the flange. As 
high as 823 larvae were captured on a single tree. The 174 trees with 
corrugated—paper bands averaged 221 larvae per tree, although the crop of 
apples on the trees was so light that the grower gave up caring for the 
Orchard in June."
