and Barnes to discuss the dollars and cents value of these data at the 
Association's annual meeting to be held at Del Monte on January 13. 
Pea weevil attacks all varieties of peas.--A. 0. Larson, Cor-— 
vallis, Oreg., reports that "Part of the time has been occupiedwan 
counting the number of weevil (Bruchus pisorum L.) stings in 73 varieties 
and strains of peas grown on the Oregon Experiment Station plots. * * * 
Some peas had as many as 17 entrance holes and one lot had 8&3 entrance 
holes in 100 peas. All here heavily infested; 35 of these varieties 
and strains have been examined from the crops of 1930, 1931, and 1932. 
* * * ‘These peas were grown in adjoining plots each year and were ex— 
posed to pea weevil attack as uniformly as possible. Although all va-— 
rieties were not uniformly attacked in any year, there seems to have 
been no consistent choice.each year." 
Early planted border of peas may aid in weevil control.--Tom Brind— 
ley, Moscow, Idaho, has made a study of the early planted border as a 
possible means of controlling the pea weevil. He was aided by an inter— 
ested grower who planted borders 10 feet wide about his pea fields 
"just as soon as the ground was sufficiently dry. * *.* Sweepings. (of 
both the borders and the main field) were made with a 15~inch collecting 
net at 150-foot intervals; 100 consecutive sweeps being made between 
each 15-foot interval. * * * The dry peas for weevil examination were 
collected at the same intervals." Results of this experiment gave proof 
that "an early planted border attracts the weevils in large numbers and 
holds them on the border until the main field begins to bloom. After 
the main field starts blooming the weevils move from the border into the 
main field, * * *" Mr. Brindley concludes that "Even though the borders 
as planted this year were not a success as far as control was concerned, 
they opened up a number of possibilities that might lead to control 
measures. The methods that seem to offer the greatest possibility of 
control are (1) burning the borders when the peak of population is 
reached, and (2) dusting with calcium arsenate." 
Ability of flour-mill insects to pass through milling rolls.—— 
George B, Wagner, Kansas City, Mo., has been making an effort "to deter— 
mine the possibility of the different stages of Tribolium sp. to pass 
through the rolls during the milling process. Two one-half gallon jars of 
mill stock were collected from each of 20 streams immediately after pass— 
ing through the rolls. These were removed to the laboratory and heavily 
infested with species of Tribolium (adults, pupae, and larvae). After al- 
lowing the insects to pursue their normal life activities for 28 days, 
they were taken to an experimental mill and allowed to go through the roll 
for which they would have been intended had they not been collected below 
the preceding roll. The samples were again brought back to the laboratory 
and allowed to stand under optimum conditions for 28 days. Results in- 
dicate that the live adults may pass through the first 3 breaks; larvae 
may pass through the 4th, Sth, 6th, tailings, sizings, and some of the 
middlings rolls; and the eggs may pass through the entire series of rolls, 
even down to the low-grade roll."
