weevils installed, or 7.07 percent, emerged. It is of interest to note 
that the activity of the weevils in the cages during April agreed quite 
Closely with the number of weevils active and removed from the cages 
between May 8 and June 30, 1933, as shown by the following table:

The emergence was higher in the cages placed in the woods, in 
which leaves-and twigs were used for shelter, than in any other cages 
at the three stations. It is now the practice to place boll weevils 
in the hibernation cages between October 15 and November 15, because 
tests for many years have.shown that a larger survival may be expected 
from weevils taken in the fields at those dates than from weevils col- 
lected before October 15 and after November 15. 
Boll weevil develops on althea.-—-Mr. Gaines also reports that 
"In August 11 weevils developed in and emerged from althea (Hibiscus 
Syriacus) buds, 5 in buds of a caged plant and 6 in buds of plants 
growing in the cotton field in the laboratory yard. The latter record 
is of particular importance because it proves that the weevil will 
deposit eggs and develop in buds of this plant under natural conditions.” 
Longevity of boll weevil.--H. C. Young, Eufaula, Okla., re- 
ports that "All weevils emerging from the hibernation cages were placed 
in glass tumblers and fed on cotton seedlings until squares became gen— 
erally abundant in the cotton fields; then they were fed cotton squares. 
On September 1, 19.05 percent of these weevils were still alive." 
Rainfall increases emergence of cotton flea hopper.—-K. P. Ew- 
ang, Port Lavaca, Tex., reports that "During the latter part of July a 
*tOtal of 4.68 inches of rain fell. This rainfall had a direct in- 
fluence on the hatching of hopper eggs in the field, materially ac- 
celerating the hatching and, consequently, rapidly increasing the nymphal 
population * * * For a number of years it has been noticed that rain- 
fall had a direct influence in increasing emergence of flea—hopper 
nymphs from hibernation cages, but this is the first time that direct 
proof of this has been obtained under open field conditions."
