fall clean-up of cotton fields. Severe early damage is therefore 
not anticipated, despite the fact that the winter has /been mild 
and sor.ie weevils have already "been found on cotton in the field. 
Survival to date in central Texas is 0.7 percent, about normal for 
this month. 
P. L. 'Thomas (April 29): Boll weevil emergence has "been a 
little more than 2 percent and is less than average in central 
Texas. Normally, half of the weevils that survive tho winter have 
moved to the fields in search of cotton bofore May 1. This year's 
figures indicate that the emergence will "be below normal. 
R. W. Mo re land (April 3<3) ; leevile hav* been fairly active 
in cages at College Station since the rains of April 25 and 26, "but 
none has been observed in the field. 
K. P. Ewing, Port Lavaca. (April 9): Observations during the 
first week of April showed continued weevil activity in stubble 
cotton and punctured squares were becoming numerous. 
COTTON PLEA HOPPER ( Psallus seriatus Heut.) 
Louisiana. R. C. Gaines (April 30): At Tal.lulah flea hoppers have 
been taken in sweeping evening primrose, but they are not as 
abundant as. at this time last year,. 
Texas. P. L. Thomas (April 22): In central Texas the emergence of flea 
hoppers the latter part of March was, with two exceptions, the 
highest since 1920. During the first 2 weeks in April it was 
higher than in 1935. a flea hopper year, indicating that early 
cotton Would have been, subject to damage had it not licon destroyed. 
Present indications arc that flea hopper damage in central Texas 
nay be reduced because of the lateness of the cotton crop. In 
northern Texas damage is not expected to be so severe as in 1937 1 
as records show flea hoppers to have been only half as numerous in 
the fall of 1937 as in 193&. Such records constitute a good index 
of the numbers that will be present the following spring. 
P. L. Thomas (April 29): Luring the last 2 weeks cotton flea 
hoppers" appear to have been delayed in hatching. With two excep- 
tions the- hatch since April 15 has been the lowest, for 12 years. 
Ordinarily S3 percent of the hatch occurs between March 15 and 
May 1. This year the numbers hatched during the 6— week period 
have been about three— fourths of normal. Late-hatched flea hoppers 
usually find their preferred weed-host plants in a desirable stage 
of growth, so that the customary early spring dispersal or migra- 
tion becomes unnecessary and fewer of the insects reach the cotton 
fields. Both adults and young have been found in Pallas County, 
and hatching has begun in weeds collected from four counties and 
caged.
