Three shipments of European parasites of the oriental fruit moth 
were received at Moorestown, N. J., in July. Three species of oriental 
fruit moth parasites have been reared from this material and liberated 
in New Jersey. The work is under the direction of Dr. Hm W.- Allen. 
Arrangements have been made to ship Copidosoma pyralidis Ashmn., 
@ parasite of the peach budmoth, from southern Europe, where it has been 
recovered by G. J.Haeussler in large numbers in connection with rearing 
for oriental fruit moth parasites, to the California Experiment Station, 
for liberation in western peach orchards. Pupae of this parasite have 
been shipped under cold storage from Nice, France, to Moorestown, N. J., 
and transcontinentally by air mail, arriving at their destination in ex-— 
cellent condition and in the remarkable time of two days from Moorestown 
and twelve days from southern Europe. H. S. Smith, of the Citrus Experi- 
ment Station, Riverside, Calif., reports practically perfect emergence 
from shipments, and large numbers of parasites available for coloniza- 
tion. ' 
Dr. JohnGray, in charge of ecology. of the oriental fruit moth, at 
Moorestown, N. J., reports that the experiments with ground screen under 
trees for the collection of migrating larvae are proving quite success— 
ful. During the period June 6 to 30, 112 larvae were recovered either on 
the ground sheet or in the Raupenleim band at the base of the peach tree. 
Drops from these trees were examined, and the majority found to be caused 
by the curculio, although there has been a moderate infestation from lar— 
vae of the oriental fruit moth. Very few moths were collected during June 
from the large screens covered with sticky tree—banding material. The 
adjacent orchards are showing a very moderate infestation, which probably 
accounts for the absence of some of the-moths on the screen. Experiments 
to detesmine the.number of twigs infested by one larva are being con-— 
tinued. 
L. F. Steiner, in charge of the large-scale bait-trap investiga-— 
tions of the oriental fruit moth at Cornelia, Ga., reports that over 
1,500 moths were captured during the month from the 2,400 traps in which 
some 100 solutions are being tested. In each of the five series two or 
more other baits are proving superior to the check, which is the ethyl 
cinnamate-—medium brown sugar bait used in the large area. The tests in- 
dicate that emulsification of the aromatic has no effect on the aitrac-— 
tiveness of the bait. They show conclusively that the use of ¢% G.c. 
ethyl cinnamate and certain other aromatics per trap makes a decidedly 
more attractive solution than where 1 c.c. is used. They aiso indicate 
that the low-grade sugars are more attactive than the medium and higher 
grades. The pure sugars, such as confectioners', granulated, and pure 
corn syrup, have proved practically ineffective. 
In order to attempt to select a chemical which might prove ef-— 
fective against the codling moth and the oriental fruit moth, an effort is 
being made to draw up a list of chemical and physical properties which 
should be combined in the insecticide. Dr. F. H. Lathrop, Vincennes, Ind., 
has discussed the matter with Dr. H. R. Kraybill, chemist, of Purdue Uni- 
versity, and has received his criticisms and suggestions. The tentative
