TOBACCO 
TOBACCO PLEA BEETLE ( Epitrix parvula Fab.) 
North Carolina. C. H. Brannon .(April 27): Many tobacco beds have been 
severely damaged this year. Practicallv all beds show evidence of 
some feeding. 
SLUGS (Mollusca) 
North Carolina. C. K. Brannon (April 15) : Slugs have been very destruc- 
tive to tobacco beds in Robeson and Columbus Counties. 
COTTON INSECTS 
BOLL WEEVIL ( Anthonomus grand is Boh. ) 
Oklahoma. C. F. Stiles (April 22): Up to and including April l6 there 
had not been any boll weevil activity in the hibernation cages at 
Eufaula, where we have 25, 55^ weevils in hibernation. So far very 
little cotton has been planted. 
PINK BOLLWORM ( Pectinophora gossypiella Saund.) 
Puerto Rico. L. C. Fife (April ik) : At Aguadilla about 5° plants of soca 
cotton bearing many mature green bolls were found growing in a field 
of planta cotton that was just beginning to bloom. Of 93 mature green 
bolls examined, 50, or 55*5 percent, were found to be infested with 
pink bollworm larvae in all stages of development. Two cotton fields 
planted December 15, 1935» a ^ Isabela were heavily infested. Of 87 
mature green bolls examined from one of these fields, hj, or ^h percent, 
were infested. In the other field 30 bolls were examined and 15, or 50 
percent, were infested. Blooms were also heavily infested in this field. 
Cotton was planted in these and adjacent fields last year. The old 
cotton plants of the 1S35 crop were destroyed only a week or so before 
the planting of the 1936 crop. In some adjacent fields the old plants 
were cut down and piled, but had not been burned. An examination of 
the seed cotton in these fields showed that it was heavily infested 
with the pink bollworm (long-cycle larvae). These facts clearly 
explain why the infestation is so high in these fields. Another 
field examined at Isabela showed an infestation of 10 percent. The 
heaviest infestation on the northern coast during 1935 occurred at 
Camuy; however, no cotton plantings in this locality are bearing 
mature green bolls at present. Two hundred mature green bolls were 
examined from two fields at Q,uebradillas on April 6. The infestations 
in these fields were 2 and U percent, respectively. Only one small 
experimental plot of Meade cotton was grown at Arecibo last year. 
During the present season, possibly 700 acres are grown in this 
locality. Two hundred mature green bolls from two fields planted 
December 15, 1935. were examined but neither field was found infested. 
At Hatillo, mature green bolls from two different fields were examined. 
Only one of these fields was found to be infested.
