COTTON" INSECTS 
PINK BOLLWORM (P ectinophora gossypiella Saund. ) 
Texas. A. J. Chapman (February): An examination of infested cotton bolls in 
the hibernation experiments at Presidio, in the Big Bend of Texas, indi- 
cated that the mortality at the close of February this year (U3 . 75 per- 
cent) was about the same as last year (U0.8O percent). Examinations 
made on February 27 in a few fields in which stalks were standing indi- 
cated that the winter had caused little mortality. 
THURBERIA I7EEYIL (Anthon omus grand is thurberiae Pierce) 
Arizona. U7. A. Stevenson (March 13): At Tucson, in southern Arizona, the 
first Thurberia weevils from infested cotton bolls that were plowed 
under and irrigated on February 5, began to emerge last week. This is 
a few days later than the first emergence of this type of weevils during 
the last 2 years. Several Thurberia weevils were out of their pupal 
cells on Thurberia plants on March 11 but, as the plants have not begun 
to bud, these weevils will undoubtedly die before food is available. 
FIELD CRICKET ( Gryllu s assimilis F. ) 
Mexico. C. S. Rude (March 23): Crickets are very numerous in the fields at 
Tlahualilo, in the Laguna. The most common species is G. assimilis . 
Fnen the cotton begins to come up the species may do considerable 
damage . 
COTTON FLEA HOPPER ( Fsallus seriatu s Reut.) 
Texas. F. L. Thomas (March 26): Cotton flea hoppers began hatching in 
small numbers at College Station, in south-central Texas, on March 18 
■and were found in the fields shortly afterwards. On warm days, about 
the 22d, many hatched in the cages.
