As has been previously noted, the Avorst infested Boll Worm districts 
seem to correspond to a certain extent with those regions in which the 
proportional area of corn is greatest. By some this is put forth as an 
objection to the trap corn method. The greater acreage of corn re- 
sults in a greater number of individual ears in which the worms can 
mature without inducing cannibalism among them. For this reason 
the first broods succeed in maturing a greater number of individuals 
which leave the corn when it matures and attack cotton. At the time, 
therefore, when the trap corn matures and the adults of the destruc- 
tive brood begin appearing, the properly managed rows of trap corn 
will be in suitable condition and will attract to themselves the greater 
portion of the egg deposition. The objection, therefore, is not well 
taken, but rather, in view of the greater number of the August brood 
resulting, the adoption of the method recommended, becomes still more 
imperative. In such districts as those just mentioned it may be advis- 
able to cut out the trap corn and feed or burn it, if examination proves 
that the egg parasites and natural enemies are not especially abundant 
upon it. These points each planter must necessarily determine for 
himself and act accordingly. 
EARLY AND LATE COTTON. 
While upon a tour of one week in August, in the worst infested re- 
gion ot Texas, the late blooming and maturing cotton (whether the 
lateness was due to a peculiarity of the variety or to the late planting 
is immaterial) was almost invariably found to be the worst infested, 
and often the only infested, cotton in any given locality. In most cases 
this explains why one cotton field is greatly infested and an adjoining 
one not, or but slightly injured; the former usually being late, the lat- 
ter early as to the time of most profuse blooming. W^here early and 
late cottons occur side by side, the latter is at a great disadvantage, for 
it actually forms a trap crop, attracting to itself almost the entire egg 
deposition, which otherwise would have been distributed over the two 
fields. 
It is therefore advisable to calculate upon having the cotton as far 
advanced as possible during July and August, for it must be evident 
that if the cotton be late and bloomiug profusely at the time when the 
destructive broods of those months appear, the attractions of the trap 
crop will be, to a certain extent, divided. From an entomological 
standpoint, it matters not whether this be accomplished by planting- 
early varieties of cotton or by planting late varieties early enough to 
attain the same end.
