W. E. Bedard, Coeur d'Alene, Idaho, says: "The examination of 127 in-— 
fested white pines on the Coeur d'Alene ‘control project showed that 
there was a concentration of parasites in the trees attacked in June 
and early July of the previous year (1932). The parasitization in these 
trees averaged approximately 60 percent. Windfalls carrying heavy 
parasitization can be readily recognized by the presence of numerous 
cocoons of Coeloides dendroctoni Cush. under the bark. Standing trees 
containing parasites can be recognized by the presence of a few of 
these cocoons at the base of the tree, which indicates a higher per— 
centage of parasitization farther up the tree. Thus, by training spot— 
ters to look for these cocoons heavily parasitized trees can be left 
and the parasites saved." 
CEREAL AND FORAGE INSECTS 
Swarming of red harvester ant in southern Texas.--"The first 
flight of sexual forms of Pogonomyrmex barbatus F. Smith was observed", 
by E. V. Walter, San Antonio, Tex., "on May 30 this year, approximately 
a month earlier than normal. Other flights were observed June 14, 15, 
and 19. * * * Qne flight was observed from the beginning at Comfort, 
Tex., on June 19 between 4:30 and 5 p. m. The sexual forms were observed 
coming from the entrance of the nest facing the wind and apparently test— 
ing the air with their antennae. After a few moments they returned to 
the nest in a somewhat excited manner. At about 5 o'clock the sexual 
forms took wing from nearly all nests in the vicinity, of which there 
were approximately 50, and flew to a point about 40 rods distant. The 
flight was observed until 6 p. m. The numbers in the air at that time 
appeared to be about the same as at any time during the previous hour. 
The number of males was about 4 times the number of females. Counts 
made in other swarms indicate that this is the approximate proportion 
found." 
Emergence of corn earworm extends over long period.—-Geo. W. Bar— 
ber, Savannah, Ga., reports that "Adults of Heliothis obsoleta Fab. have 
emerged from hibernation throughout the month of June this year as here-— 
tofore. The earliest emergence from hibernation this year was on March 
29, So that up to the present time emergence has occupied a 3-months' per— 
iod. In the experiments, up to the 26th of this month, emergence of 
moths was recorded on 1 day in March, on 16 days in April, on 29 days in 
May, and on 22 days in June." 
Light lubricating oil as possible substitute for water and molas— 
Ses in grasshopper baits.--According to J. R. Parker, Bozeman, Mont., 
"R., L. Shotwell, who is working in the vicinity of Dickinson, N. Dak., 
reports good results with grasshopper baits containing cheap, light lu- 
bricating oil as a substitute for water and molasses in ordinary baits. 
such baits compared with the best standard baits have consistently stood 
near the top in plot and cage experiments where kills made only after 
several hours of feeding were the basis of comparison. In larger field
