More on the cotton flea hopper.--Reports from T. C. Barber, Browns- 
wille, Tex., indicate that the cotton flea hopper is begining to re- 
cover from the effects of the hurricane in September 1933. Two speci- 
mens were collected on horsemint on April 19 and. several more have been 
taken in sweepings since that time but they are still surprisingly 
scarce, considering the unusually large quantities of blooming horse- 
mint. None had been found on cotton up to May 1, although the plants 
were a foot tall and were producing squares. 
K. P. Urwing, Port Lavaca, reports that owing to the cold, wet 
spring, the cotton crop is ieter than last year, with considerable 
acreage not planted by May 1. Hatching of flea hoppers from overwinter-— 
ing efgs in hibernation cages is also later, emounting to 59 percent 
of the number hatched last year by the end of April. The first adult 
wes found on primrose in the field on April 9, the same date that the 
first one matured in the insectary. Fron this date on the population 
rapidly increased and nigration, as siown by catches on tanglefoot 
screens, started on April 1/7, although tue first adults and nymphs were 
“not taken on cotton until April ou, At Port Lavaca emergence records 
“rom 10 hibernation cages containing Croton capitatus plants collectec 
at weekly intervals beginning September 1, 1933, show the least emer— 
rence to be 156 nymphs from 100 plants collected September 1, and the 
highest, 4,264 nymphs from plants collected on October 27. The five 
collections made in September averaged 964.4 flea hopper nymphs per 
100 plants, whereas the five collections made from October 6 to Novem- 
ber 4% averaged 3,352.2 nymphs per 100 plants. From all the cages 
(3,700 plants) 22,837 nymphs emerged in April. ‘The peak of the emer- 
gence was during the week of April 15 to el, wher 13,466 nymphs emerged. 
The peak last year was reache’| approximately three weeks earlier. The 
highest emergence for any dey this season vas 4,280 nymphs on April 15. 
The lowest daily emergence for the month was 19 on April 14, follow-— 
ing the coolest day of the month, when the maximun temperature was 
70° F., ani the minimum was 50° F, ‘whe mean temperature, O° F. on 
April 15, was 5° lower shen on any other day curing the month. 
Groton clean-up 27 Selhoun County, Teras.--Although it is too 
early to draw conclusicns as to the value or results of the CWA campaign 
in Calhoun County during the past winter, a comparison of the number 
of flea hoppers collected on the flight screens during April 1933 anc 
-kpril 194 gives an indication as to Sits effectiveness. This year 
12 screens collected 79 fka hoppers, or 6.58 per screen, during April, 
whereas last year 5 comparable screens collected 615 flea hoppers, 
or 102.5 per screen. The screen collections indicate that there were 
15.57 times more flea hoppers sn the fields of Calhoun County in April 
1933 than in April 193, The effectiveness of the clean-up campaign 
is clso indicated by a comparison of the flea hopper infestation rec -— 
orfiss mede in cotton fields curing April in Calhoun County and the 
adjoining county of Victoria, where the croton plants were not destroyed. 
Only 8 flea hoppers were found on 3,000 cotton plants in 15 fields in 
Calhoun County, while in Victoria Couuty 55 flea hoppers were found on
