insects or in some other manner caus,
ing the boil to rot. The Pink Boil
worm is found in green bolls and hard
,ly ever in a boil which shows any
sign of rot
AS to the difference in structure
1.-THE Pink Bollworm is much larger both
as to length and breadth. 1t has the
appearance of being "chumpy." The
skin is rather thick and nOn-tranSpar-
ent and the pink color is distributed
Cross-wise on each segment giving the
back Of the worm a ridged appearance.
The SCaVenger worm has a thin skin
and is transp. rent showing the dark
matter Of which the insides are COM
posed. The c0loring is more uniformly
distributed so that the worm appears
to be a full pink color without the
ridged appearance. The pink color Of
| the sCavenger worm is a deepr celOr
and in most cases almost red. The
length of the full gown Pink Boil
worm is about IL inch, whereas the
length of the scavenger worm is only
about IA inch
! Again if a Pink bOllworm and a
ScaVenger worm are placed side by
side with their under sides up, and
with the aid of an ordinary hand tense
the following point will be noted:
That the hairs on the prolegs Of the
Pink BollWOrm will be seen to have
the shape of a horseshoe while those
on the prolegs of the scavenger worm
will have the form of a circle. The
prolegs referred to are false legs" To-
Gated on the abdomen, there being
eight in number. The real legs are
six in number and are located Just
back of the head.
These distinguishing differences of
the two worms are not the only differ
ences however and the ohtrs can be
determined by the use of a microscope
but for field use the above differences
can readily be determined and having
found real Pink Bollworm in the cot
ton field it is easy to find a scavenger
worm for comparison and with the aid
of the bolls which show the work OF
each there is little chance of making
a mistake in thinking that the scaven-
ger worm is the same as the real Pink
Bollworm.
Worm Carried in Cotton Seed.
1t should be borne in mind that the
Pink BollwOrm is carried from place
to place in the cotton seed and in this
way it has gained entrance into many
countries as well as our own. There
is very little chance that the moth or
adult stage of the Pink Bollworm can
be carried to any great distance by
winds for it is very fragile insect
and would soon die if blown very far.
1t is also known that the moth does
not fly very far and consequently the
spread of the pest in this way is not
so great, except Of course in the i'm
mediate vicinity of weber the moth
first emerged.
There is very great danger in plant.
ing cotton in new area If the seed
was obtained from an area infested
with the Pink Bollworm. Even if the
seed was shipped from an uninfested
area into an infested area and then
was reshipped out of that area to be
planted it would be very unwise to
use it for planting purposes.
If any farmer has obtained cotton
seed from within what is now the
quarantine area it should not be plant
ed but should be burned Immediately,
and other seed obtained and planted
in its stead. Don't try to fool your
self into believing that your seed are
free from the worms if the seed came
from within an infested area, for the
seeds are considered VERY DANGER
GUS, and your field stands very
great chance of being infested this
year.
The Work of the Departments.
Both the United States Department
Of Agriculture and the State Depart
ment are making war on this pest.
Both departments have men stationed
at various points within the quaran-
tine area and elsewhere. The State
artment at pesreitn -IboIIIIIIIIIIIIII
department at present is making a
thorough combing of the quarantine
