Trap plots were used again in the spring of 1935. The cotton was planted in 
the field, instead of being grown in hotbeds, and later transplanted, as was 
the case during the two previous seasons. The plots ranged in size from one- 
fourth to one-half acre. Owing to unfavorable weather, the cotton did not 
begin growing as fast as was expected, but weather conditions also delayed the 
field cotton, and the trap cotton began blooming at least a month in advance 
of the field cotton. Bloom collections were begun on May 20. and within a few 
days infestation was found in several of the plots. At the end of the fiscal 
year infestation had been found in all 13 plots, and a much larger number 
of worms is being found this year than last. This may be owing to a differ- 
ence in the emergence of moths each year. On the other hand, it may be be- 
cause the field clean-up was a little later this year, on account of the top 
crop mentioned above. If so, it indicates very clearly that the earlier the fields 
can be cleaned each fall the fewer moths there will be the following spring, 
as worms will have less time to enter the soil for hibernation. The delayed 
planting date of April 15 was satisfactorily observed. Field cotton in Brewster 
County has just begun blooming, and a few worms have Ireen found, but the 
cotton in Presidio County is considerably later, and no blooms have yet been 
produced. 
NEW INFESTATION IN TEXAS 
The new infestation in Texas involved Andrews and Ector Counties and all 
but a small part of Midland County. The last is not a new infestation, as 
this area was previously under regulation, having been released February 28, 
1933. The last findings had consisted of 2 specimens in the 1931 crop. On Octo- 
ber 18, 1934, a specimen of the pink bollworm was found in trash at Midland. 
This was followed by additional findings on October 23 and 24. Owing to the 
lack of ginning facilities, cotton produced in Andrews and Ector Counties is 
ginned at Midland, hence they were involved in the infestation. On October 
24, 1 specimen was found in gin trash at Stanton, in Martin County. An 
examination of the gin records showed that most of the cotton from which 
the trash came had been produced in Midland County, with only a few fields 
from Martin County represented. Intensive inspections were made in these 
Martin County fields and the gin trash from the remaining cotton was caught 
separately and inspected without any indication of infestation being found. 
It seems almost certain, therefore, that the above specimen originated in 
Midland County, and this information did not seem to warrant including Martin 
County in the regulated area. Inspections were continued during the remainder 
of the ginning season without finding any additional specimens. It will thus 
be seen that, as was the case in other new areas, the infestation in this area 
is very light. 
The three counties mentioned above were again placed under regulation, and 
the movement of products therefrom was handled accordingly. Inasmuch as 
the ginners had had previous experience with the regulations, they cooperated 
whole-heartedly. 
CHANGE OF INSPECTION METHOD IN REGULATED AREAS 
Heretofore gin-trash inspection has been made in each county under regu- 
lation to determine whether or not infestation was present, and if so to what 
degree. In the fall of 1933 green bolls had been collected from a number of 
lightly infested counties and were later inspected as a check on the laboratory 
method. It was demonstrated that a rather light infestation could be discovered 
by this method. Therefore, as an economy measure, a plan was worked out 
whereby a number of gin-trash crews could be eliminated and at the same 
time a check on the infestation condition could still he taken, although some- 
what delayed. This plan is to collect green bolls in the fall in counties where 
infestation has existed for some time. The bolls are preserved and inspected 
later in the season, as regulatory activities decrease. In case no Infestation 
is found in the bolls, gin-trash inspection is to be substituted the following 
season. 
SITUATION IN OLDER REGULATED AREAS 
Intensive gin-trash inspections were carried on in the older regulated areas 
of northern Florida and Georgia. In Madison County, Fla.. 1 specimen of 
the pink bollworm was found, but in the other counties of Florida and in the 
three counties in Georgia the results were all negative. Intensive inspections
