hopper populations in North Dakota during the first three weeks in Aug-— 
ust shows that "grasshoppers are present in sufficient numbers to cause 
some damage next year in every county in the State, ranging from local 
outbreaks in the lighter infested counties to county-wide damage in the 
more heavily infested areas. It is highly signifant that while Melano— 
plus bivittatus Say and Camnula pellucida Scudd. were dominant over the 
eastern two thirds of the State in 1932, M. mexicanus is now the dominant 
species over the entire State. The greater abundance of this third spe— 
cies complicates both survey and control work, because of its habit of 
scattering its eggs throughout stubble fields." 
Feeding of range caterpillar parasite greatly extends longevity.—— 
Reporting on food tests with 280 Anastatus semiflavidus Gahan as a par-— 
asite of Hemileuca oliviae Ckl1l., V. L. Wildermuth, Tempe, Ariz., says: 
"The parasites were taken from emergence cages that were examined every 
24 hours. Only female parasites were used in the tests * * * The par— 
asites were placed in shell vial cages 1 inch by 5 inches, the upper 
end being closed by a one-holed cork stopper, the lower with a large 
cotton plug. Food, in liquid form, was usually supplied by saturating 
a small cotton plug that filled the hole in the cork at the top of the 
cage. These tests were carried on in a tempareture control room at ap— 
proximately 75° F. Usually 5 or 10 females were used in each test. * * * 
With 100 parasite females given no food, water, or host eggs the aver— 
age length of life was 2.€3 days; maximum 4 days, and minimum 1 day. 
The maximum, minimum, and average lengths of life of 80 females given 
water only were 8, 1, and 3.2 days, respectively. When Hemileuca oliv— 
iae eggs alone were supplied the average life of 50 individuals tested 
was 2.8 days, with a maximum of 10 days and a minimum of 1 day. Fifty 
females fed honeywater, 1 to 4 solution, lived an average of 23.56 days, 
74 days being the longest and 3 days the shortest period of life."

Boll weevil survival.--R. C. Gaines, Tallulah, La., reports 
the final results of the emergence of boll weevils in the hiberna— 
tion cage tests conducted at Tallulah by G. L. Smith; at Florence, 
S. C., by F. F. Bondy; at College Station, Tex., by E. W. Dunnamsjame 
at Eufaula, Oxla., by H. C. Young. A total of 133,300 weevils were 
placed in the hibernation cages last fall; 500 were placed in each 4by4 
by 4 foot screen-wire cage on or about Oct. 15, Nov. 1, and Nov. 15, 1932. 
At Florence, Eufaula, and Tallulah 70 cages were installed but at College 
Station cold weather and snow interfered with the November 15 installa— 
tion and only 57 cages were installed at that place. The severe winter 
of 1932-33 caused a high mortality in the western part of the area 
infested by the boll weevil. At College Station not a single live weevil 
emerged after May 8 from the 28,500 placed in cages last fall. At Eufaula 
only 22 of the 35,000 weevils, or 0.06 percent, emerged; and at Tallulah 
oe of the 34,800 weevils placed in cages, or 0.15 percent, emerged. 
At Florence, where the winter of 1932-33 was milder, 2,476 of the 35,000
