Press Bulletin No. 34..

Experiment Station.



At this season if one examines the backs of cattle a
varying number of lumps the size of a pecan nut may be
noticed. Those small tumors contain, as many know,
the warble, grub, or wolf. They are a source of great
irritation to the animal, and should be removed.
The marble, grub or wolf is the larval stage of a fly
known as the gad-fly, or scientifically as HYPODERMA
LINEATA. When an animal is attacked by the fly it
shows its fright by bellowing, running off from the
herd with head and neck extended and with the tail held
straight and with trembling motion.
The fly lays its egg on the back attaching it to a hair.
The egg hatches out, and as one author states, the em-
bryo is licked off by the animal and swallowed or lodged
in the back part of the mouth or gullet. Later the war-
bles appear under the skin, they being supposed to have
passed through the body to the surface. After the war-

ble has located itself, it bores a hole through the skin
and remains there in a sac until it reaches a certain size.
It then squeezes through the hole, falls to the ground,
buries itself, changes to the pupa stage, and later becomes
a fly like its progenitor.
TREATMENT.-This consists only in removing the war-
ble when it appears. I prefer doing this by nicking the
edge of the opening and by gentle pressure around the
base of the tumor with the ends of the fingers and thumb
thts forcing the warble out into the palm of the hand.
Frequently they may be forced out by this means with-
out using the knife. If the pressure is not properly ap-
plied the warble slips away under the skin and cannot be
removed easily, Some persons inject a few drops of
turpentine or kerosene by means of a small oil can, stat-
ing that the warble will crawl out in a day or two. I
have known cows to return to their feed the next day af-
ter the warbles were removed.
