THE OX WABBLE FLY.

9«at ud Most Efficient Way to Get Bid of the I’cKt Is to Destroy the jjlngs'ot. The warble or swel! in'g on the back of cattle is caused by L.e larva of a fly Which attaches its eggs to the hair on the legs, flanks and neck of the animal. These hatch and the larvae establish themselves under the skin, usually on either side of the backbone. Here they feed upon the animal juices until ready to pupate, causing the swelling or warble. When growth is completed the grub leaves the warble, drops to the ground,' crawls under the 1 most con-

Tenieul shelter, such as a piece of board, log, etc. and here .transforms into the fly or adu l l stage, '['here is a difference of Opinion as to l ow the grub gets under the* skin. Some entomologists claim that the egg is taken into the stomach by the animals licking themselves, hatch there, : adhering to the walls, then the grubs gradually work their way toward the surface, where they remain until fully grown. Others hold that the eggs hatch where they are laid and the young larvae bury themselves at once

under the pkin. Whatever method la employed the results are the same. The best way to get rid of the pest is to! . aggot. This may be done t- ,-Jng them out.

Train oil can be used alone. Ab the fly does hot move about from place to place freely, its eradication- on individual farms depends almost completely upon the owner.— Orange Judd Farmer.
