D. J. Caffrey, of the European corn borer laboratory, Arlington, 
Mass., reports as follows on the recovery of parasites of the corn 
borer: "Credit should be given for North Central States data to W. A. 
Baker, of the Monroe, Mich., laboratory. * * * Masicera senilis Rond. 
is most outstanding in both two-generation and cne-generation areas, 
having been collected from 37 towns in the former and 22 towns in the 
latter. It is becoming a decided factor of control in the East and is 
firmly established over a wide area in the North Central States, the 
vicinity of Jerusalem and Perkins, Ohio, and the Silver Creek, N. Y., 
secticns especially. Inareolata punctoria Rom. is second in importance, 
having similar status to senilis in the Massachusetts area but not being 
as widely dispersed. In the one-generation area it is showing up best 
Seine oilver Creek, N, Y., section, although recoveries haye been made 
in Jerusalem, Ohio, and York, Ind. Eulimneria crassifemur Thoms., Phae- 
ogenes nigridens Wesm., Zenillia roseanae Br. andBerg., andZ. mitis Meig. 
are of about equal status in the eastern section, with establishment 
certain, and in limited areas each is of increasing economic importance. 
None of this group have been recovered in the North Central States 
except crassifemur at Jerusalem and roseanae at Perkins, Ohio. Mic- 
rogaster tibialis Nees has been recovered from 4 towns in Massachusetts 
and from 13 towns in the North Central States, showing better estab— 
lishment there." 
COTTON INSECTS 
G. A. Maloney, Tallulah, La., observed that boll weevils "continue 
to be more or less active in flight, owing to mild temperatures prevail- 
ing during the present winter, 9¢ weevils being taken from field screens 
on January 14 in Madison Parish, La. Live adults, larvae, and pupae 
were found in cotton bolls on January 16 in Madison Parish. Weevils 
were also found breeding in cotton blooms near Lucedale, Miss., during 
the last week in January." 
Gel Smith. J..C. Clark, and A, L. scales reporty as, JOLlowoacn 
the result of flight screen studies: "It is noticed that the peak of 
weevil movement in December occurred between December 12 and 14, when 
“the range of temperature was 78° to 80° F. maximum and 64° to 66° F. 
minimum. The peak of weevil movement in January occurred between Jan- 
uary 14 and 18, and the range of temperature was 19° 4Q, (Oo Fee he aie 
mum and 56° to 66° minimum. Apparently a few days with a temperature 
around 70° is necessary to stimulate movement of the boll weevil dur= 
ing the hibernation period. * * * The cotton fields between the levee 
and river at Mound, La., which showed a weevil population of 1,614 per 
acre by the hoop and bag method on December 14, were surveyed on Janu- 
ary 16, at which time the peak was reached in weevil collections on 
the flight screens and the following results were obtained: All green 
foliage was killed by frosts occurring early In January. Immature 
bolls on some plants were somewhat green and in these bolls live larvae 
and pupae were found. Several live adults were also found under bracts
