ANNOUNCEMENTS RELATING TO PINK BOLLWORM 
QUARANTINE (NO. 52) 
CONFERENCE ON PINK BOLLWORM OF COTTON CALLED FOR DECEMBER 15, 1939 
[Press notice] 
November 9, 1939. 
A conference to discuss control of the pink bollworm of cotton in the United 
States has been called by Dr. Lee A. Strong, chief of the Bureau of Entomology 
and Plant Quarantine. The meeting will be in the Little Theater, San Pedro 
Park, San Antonio, Texas, at 10 a. m., Friday, December 15. 
Since 1917 the efforts of the Federal Government, in cooperation with the 
States concerned, to suppress the infestations of this pest have served to keep 
it in check. Since 1936, however, when the first infestation was found in the 
lower Rio Grande Valley of Texas and the adjoining territory in Mexico, there 
has been an increase in the population of the insect despite suppressive 
measures. 
In the Rio Grande Valley the pink bollworm finds conditions particularly 
favorable to its development. There has been enough survival each year to 
explain in part at least the increase in distribution of the pest The infestation 
in the Rio Grande Valley threatens the entire Cotton Belt of the United State-, 
entomologists believe. 
According to Dr. Strong, the most effective way to suppress the pink boll- 
worm is by the complete elimination of all cotton plants from the infested 
areas for 1, and in some cases 2 years. The cost of such a program or an 
alternative program of continued cleaning of the fields in the south Texas 
infested areas means huge outlays of Federal and State funds.
