i.2 to 1.5 miles from the nectar source showed an average net gain per 
colony of 45 pounds and 15 ounces, while 31 colonies: located within the 
nectar source showed an average net gain per colony of 72 pounds and 
2 ounces. Of the colonies located at Laramie, Wyo., on which similar 
observations were made, 10 colonies located on the peters campus, 
approximately 1 1/2 miles from sweet clover, showed an average net gain 
per colony of 152 pounds and 11 ounces, while 9 colonies located within 
the nectar source on the Sechrist location showed an average net gain 
per colony of 209 pounds and 6 ounces, and while for 10 colonies located 
; at the station apiary on the Hatch ranch, with sweet clover to the south 
and west partly surrounding them, the average net gain per colony was 
177 pounds and 3 ounces." 
DECIDUOUS-FRUIT INSECTS 
W. P. Yetter, jr., in-charge of bait-trap investigations of the 
oriental fruit moth fuespeyresia molesta Busck) at Vincennes, Ind., sub— 
mits a summary of results obtained during 1931. From a dissection of 
/#,107 moths he counted 113,910 eggs, or an average of 54.62 eggs per 
moth. Out of 12,769 moths examined he found practically even division 
between males and females, i.e., 49.44 per cent males and 50.56 per cent 
females. 
L. F. Steiner, Cornelia, Ga., makes the following further comment 
on the season's bait-—trap work for the oriental fruit moth:’ "The abili- 
ty of the oriental fruit moth to fly long distances will prevent the 
use of bait traps as a control in any but large or isolated peach or-— 
chards or by several growers on a cooperative basis unless a bait can 
be developed which is attractive enough to prevent all oviposition in 
its vicinity. If the baits at Cornelia attracted moths a mile in other 
directions as they did from the east, the 42,000-trap experiment af- 
ected the fruit moth population over an area of at least 10 square 
_ Miles. Baits in use at present can not successfully compete against the 
‘odors eiianating from the foliage of the peach tree. To be most attrac-— 
_ tive tney must be placed in or near the foliage. Away from the tree 
they capture practically nothing." 
H. G. Butler, Harriman, Tenn., reports that the following parasites 
of the oriental fruit moth were reared in the numbers given from larvae 
taken in twigs in orchards in the vicinity of Harriman: 'Cremastus minor, 
Cush., 1; Cremastus n. sp., 10; Eubadizon n. sp., 2; Glypta ruiscutellaris, 
_ Cress., 2; Lixophaga mediocris Aldrich, 3; Macgrocentrus ancylivora Roh. 
(introduced from New Jersey), 18; Macrocentrus delicatus Cress., 1,550; 
_Microbracon mellitor Say, 2; Pristomerus ocellatus Cush. (introduced from 
Europe), 8; unidentified, 9. The determinations were made by the Bureau 
_ specialists in the various: groups." 

The two final shipments from Europe of parasites of the oriental 
fruit moth were made by G. J. Haeussler and J. Balakine on September 4
