10 TKE CATTLE TICK CAN BE DESTBOYED 



shows much activity, seldom moving far from her original point of 

 attachment. She still has to undergo most of her growth. After mat- 

 ing, the female increases very rapidly in size, and in from twenty-one to 

 sixty-six days after attaching to a host as a seed tick she becomes fully 

 engorged and drops to the pasture, to repeat the cycle of development. 



Summary of Life History 



To sum up, on the pasture there are found three stages of the 

 tick — the engorged female, the egg, and the larvag and on the 

 host are found four stages — the larva, the nymph, the sexually mature 

 adult of both sexes, and the engorged condition of the female. 



Methods of Eradication 



In undertaking measures for eradicating the tick, it is evident that 

 the pest may be attacked in two locations, namely, on the pasture and 

 on the cattle. 



In freeing pastures the method followed may be eitlaer a direct or 

 an indirect one. The former consists in excluding all cattle, horses, 

 and mules from pastures until all the ticks have died from starvation. 

 The latter consists in permitting the cattle and other animals to con- 

 tinue on the infested pasture and treating them at regular intervals 

 with oils or other agents destructive to ticks and thus preventing 

 engorged females from dropping and reinfesting the pasture. The 

 larva on the pasture, or those which hatch from eggs laid by females 

 already there, will all eventually meet death. Such of these as get 

 upon the cattle from time to time will be destroyed by the treatment, 

 while those which fail to find a host will die in the pasture from 

 starvation. 



What Tick Eradication Means 



The eradication of the cattle tick in the South means the awaken- 

 ing of a new industry. It means an immense market for the produ- 

 cers of registered cattle of all breeds. 



The United States Bureau of Animal Industry is co-operating with 

 the officials of the Southern states in striving to accomplish this 

 laudable work in the shortest possible time. 



The tick has been the cause of the lack of interest in cattle raising, 

 because it made necessary the .establishing of an ocean to ocean 

 quarantine line, separating the cattle grown in the South from the 

 best markets of the Union. 



Deprive any commodity, grown or manufactured, from the best 

 markets of the world, I care not what it may be, cotton, corn, cattle,
