Groji Loss Caused by the Activities of tht 

 Warbh Fly. 



One of the most trying insect pests that 

 infest cattle is the Warble fly. It not only 

 irritates the cattle to a marked extent, but 

 it weakens the milk flow, badly affects the 

 flesh and destroys the value of the hide. 

 By its pertinacity and viciousuess it thus 

 causes enormous loss to the breeder, the 

 farmer, and to the vendor of products de- 

 rived from live stock. The loss caused can- 

 not be estimated with even approximate 

 exactness, but sc»me idea of it may be 

 gained from the fact that responses re- 

 ceived to enquiiies made under instruction 

 of the Veterinar\- Director General of the 

 Dominion show that the loss in hides dam- 

 aged by Warble flies runs to from 25 to 30 

 per cent. Tanners tlaim that hides thus 

 damaged are dear at almost any price. They 

 are agreed that rough, long-haired, ill-kept 

 animals are the most subject to the pest, 

 weU-fed, sleek, well-cared for animals being 

 generally immune. Thus the presence of 

 the Warble fly is fairly good evidence of 

 neglect. A bulletin prepared and Avritten 

 by the Chief Animal Pathologist of the 

 Health of Animals Branch at Ottawa. 

 dealing with the subject, states that there 

 are two classes of the fly, one known as 

 Hypedenna lineaiam, which lays its eggs 

 around the comet, fetlock, knees and hocks. 

 during the latter part of April. The second 

 is known as Hypoderma hovis, which at- 

 tacks the hindquarters and legs in June. 

 but continues active for over fifty days. 

 while H. lineatum limits its activities to 

 eighteen days. The story told in the bul- 

 letin is of investigations started at Agas- 

 sLz, B.C. in 1911. and conducted for a num- 

 l>er of years, the object being to discover 

 means for eradicating the pest, reveal its 

 methods and habits, and show the damage 

 and loss it causes. In summing up, the 

 author says that animals should be housed 

 during the heat of the day to prevent the 

 flies attacking thern and layinsr their etrtrs. 

 and that the grubs should bf ^\uf'f7.e(\ out 

 as early as possible.
