The Red Soldier Bug or Cotton Stainer.
(Dysdercus suturellis)
The cotton stainer is so called from its habit of stain-
ing the cotton in which it is working an indelible red or
yellowish color. It punctures and sucks the young bolls,
preventing them from coming to maturity, and is also a
disastrous enemy to the fruit of the orange. It punctures
the rind of the orange and sucks the juice, without leav-
ing any marks of the mischief it has done. However,the
punctured fruit is sure to fall in a day or two and even if
picked at once will decay before it is shipped any dis-
tance. The insect and other related ones have been more
than ordinarily destructive this season, both in cotton
fields and orange groves.
The eggs are dropped on the ground among heaps of

cotton seed or other material upon which the bugs feed;
and the food plants are evidently not restricted to cotton
and orange. The young are bright red in color with black
wing-pads and have yellow lines to mark the separation of
the body into segments. The adults are about one-half
inch long, the blackish wings being crossed with narrow
bands of light yellow, fancifully resembling shoulder
straps; hence the name, "soldier bug." It seems to breed
continuously, all stages being found at all seasons.
REMEDIES: NO cotton or cotton seed should be left
ungathered in the field for them to breed in. There has
been a marked abatement of the nuisance throughout
the South since all the seed has been utilized for manu-
facture into meal. Small heaps of cotton seed and
fallen oranges or bits of sugar cane may be scattered
throughout orange groves as baits and breeding places
for the insects. As soon as they appear in numbers
about the heaps, spray with kerosene mixture or use
scalding water. Spraying sometimes helps. A corres-
pondent who has achieved at least a temporary success
writes: "First, we sprayed the trees with a solution of
tree soap (that manufactured by Bowker), using a pound
of 7 or 8 gallons of water. Some of the trees
were well reddened with the bugs. We killed a few
Second, the next day we cleaned up all the fallen fruit
and buried with lime.
The next day we sprayed again, inside and out, and
then put Tanglefoot fly paper around the trunks (also
used pitch tar on some, painted on trunk). This was
done with an idea of keeping the young bugs and those'
adults that had fallen from crawling up again. They sat
below in scores.
Third, the next day we sprayed again, and we have

sprayed once since. To-day the bugs are practically all
dead. I do not think there is one where there were a
hundred. What the spray will do to the fruit I do not
know yet."
Spraying would be a more certain remedy if the insects
were not continually coming in from the outside after the
treatment has been given. Under a fumigating tent I
have dropped 890 cotton stainers from a 12 foot tangerine
tree, using hydrocyanic acid gas. Fourteen specimens of
the green soldier bug were dropped at the same time.
Fumigating can be useful only where the insects mani-
fest a tendency to congregate upon particular trees and
when they first appear; persistent and industrious war-
fare by spraying, hand-picking or fumigating, according
to circumstances, will pay well at this time.
