mest satisfactory method of making the inoculation is to remove the entire 
head from the insect, grind it uy, and place it in normal salt solution. 
Inoculations have been made using normal salt solution, 2.5 per cent hy— 
drochloric acid, and the ground heads of Lvgus pratensis L. or Psallus 
seriatus Reut. in salt solution. Mr. Cook says: "All inoculations were 
allowed to develop in the field for 5 days and daily notes were taken on 
them. After the fifth day they were brought into the laboratory and given 
a thorough examination under the binocular. Most of the inoculations were 
sectioned freehand, placed in formalin-—acetic—alcohol and kept until they 
could be stained and permanent slides made. Inoculations showing good 
damage were not sectioned freehand, but the entire damaged area was cut 
from the petiole and placed in formalin-acetic-alcohol. This material 
will be later run up in paraffin and sectioned in the microtome." 
At the Tullulah laboratory, P. A. Glick, J. M. Yeates, and as— 
sistants made 35 airplane flights during July, collecting insects, using 
a total of 27 hours and 30 minutes in the exposure of the screens. They 
report a total of 250 insects collected in the upper air. Among the more 
interesting records of insects taken are: At 200 feet, 1 large pentato— 
mid, 23 winged ants, 1 honeybee, 1 Ceratomegilla fuscilabris Muls., 
1 Stictocephala festina Say (alive), and 1 Geocoris punctipes Say; @2 
Arctocorixa modesta Abb, at 500 feet and 1 at 1,000 feet, and 1 species 
of Chrysopa at 2,000 feet. The last four were taken during night flights. 
On the same days and nights that insects were collected by airplane, 
Ssweepings were made to collect insects on the surface, so that they may 
be used for comparative studies. 
K. P. Ewing, Tallulah, La., reports: "Sweepings were made at 
weekly intervals on about 24 weed host plants and cotton to determine the 
population of Psallus seriatus Reut., Lygus pratensis L., and Adelpho— 
coris rapidus Say on their respective host plants. A total of 400 sweeps 
was made on EFrigeron annuus during the first 2 weeks in July, resulting 
in an average of 1,920.5 Lygus pratensis per 100 sweeps. Sweepings were 
. discontinued on this plant about the middle of July, due to the plant dying 
out. The average numbers of Lygus pratensis per 100 sweeps on red clover 
and alfalfa were 158.4 and 167.5, respectively. A total of 500 sweeps on 
Croton showed an average of 654.2 Psallus seriatus per 100 sweeps." Re= 
sults of weekly sweepings on cotton in the vicinity cf Tallulah show a 
gradual decrease in mirid population, frem 23.4 mirids the first week in 
July to 13.7 the last week. 
INSECTS AFFECTING MAN AND ANIMALS 
BE. W. Laake investigated an ocutbreak of blood-sucking midges in 
the vicinity of Little River and Temple, Tex., in July. He found en-—- 
gorged females in considerable numbers on the walls of poultry sheds and 
houses. The midges apparently do not attack man, but poultry are suffer-— 
ing greatly from their attack. Fifteen young turkeys on a farm near 
Little River were killed by these insects in one night.
