A. A. A. ALLOTS MONEY FOR WORK ON TOBACCO-PRODUCT INSECTICIDES 
In the hope of broadening the use of tobacco products in insecticides, 
thereby providing a means of disposing of additional quantities of the 
low-grade tobacco and thus aiding in the orderly marketing of this crop, 
the Agricultural Adjustment Administration has, transferred to the Bureau 
$3,900. The funds transferred have been allotted to the Divisions of 
Fruit and Shade Tree Insécts, Truck Crop and Garden Insects, Insects Af- 
fecting Man and Animals, and Physiology and Toxicology, and will remain 
vavailable during the current fiscal year.. This.small allotment will per- 
mit the expansion of certain activities to include tests in determining 
the effectiveness of various nicotine compounds: on certain insects for the 
control of which insecticides other than nicotine are now recommended. 
charge of the oriental fruit moth work at Moorestown, N.-J., reports that 
the emergence of parasites from two large shipments of field-collected 
oriental fruit moth larvae from Japan was completed: in August. The total 
number of larvae forwarded was 142,554 and from these 87,091 parasites 
emérged, a general parasitization of 12.6 percent of all emerged material. 
The parasitization of larvae from Chosen (Korea) was 36.5 percent as com- 
pared with 5.6 percent from Japan. 
During August and September 9 species of imported parasites, the 
greater number’ being Phanerctoma grapholithae Mues., Dioctes moglestae Uch., 
end Macrocentrus thoracicus Nees, were liberated in various eastern peach- 
growing sections. sy , 
Fruit moth bait-trapping results.--W. P. Yetter and L. F. Steiner, 
Cornelia, Ga., have summarized their season's work with bait traps for 
the control of the oriental fruit moth. Among the important developments 
of the past season has been a corroboration of previous results as to 
practical control. One orchard was baited for the purpose of demonstrat-— 
ing the value of the bait traps and in two other orchards a .large propor- 
tion of the trees were baited in the course of experiments: to. determine 
he relative attractiveness of various materials. In these three orchards 
the oriental fruit moth infestation was 77.6, 46.4, and 77 percent, re- 
Spectively, less than that in unbaited orchards some dist-nce avay. These 
orenards were cmaller than the general areas baited in previous years. 
The cutsvanding bait used was terpenyl acetate 1/2 ¢ c per trap in ae 
percent wedium soft sugar. These results as to practica™ control were 
corroborated by the recoveries of marked moths that had been released in 
the orchards. In two of the experimental orchards the recoveries of 
liberated moths were 73 and 64 percent, respectively. Dissection of the 
captured moths shows thet comparatively few eges had been laid before 
they were telcen. Experiments with marked moths indicated acain that 
after ativest a general movement of : 
proportion of tha 
the moths occurs. <A much smaller 
moths were captured after the fruit had been removed 
from the orchard. It is believed that unless ail. orchards in an area are 
baited little or nothing would be accomplished by the continuance of 
trapping in individual orchards after harvest time.
