Injurious to Man. 45 



Newstead states of this tick : "To man it is the greatest pest 

 of the island [of Jamaica], attacking him in all its stages from the 

 larval to the sexually mature males and females. It is a most 

 vicious biter, and when it has gained access to the skin inserts its 

 mouth-parts (capitulum), the adults producing an irritating wound 

 followed often by intense itching. . . ." 



Amblyomma americanum, Linnaeus. 



Owing to its habits this tick is of considerable economic 

 importance, for it readily attacks domestic animals and man.

The Lone Star Tick (Amblyomma 

 americanum, L.). Female, 

 enlarged. (After Banks.) 



According to Hooker, Bishopp, and Wood, in the Eastern and 

 Southern States of North America human beings are more 

 frequently attacked by this tick than by any other species. 

 It is troublesome to milkers at dairies and also to people 

 who keep poultry. This species is called the lone star tick, 

 because of the conspicuous silvery spot on the shield of the 

 female. 



The hosts of Amblyomma americanum are very numerous ; it 

 is said to bite almost any mammal, and also birds (poultry, etc.). 

 This species occurs in Labrador and Southern Manitoba, in nearly 

 all the States bordering on the Atlantic and Gulf of Mexico, and 

 also in several inland States. It is also found in Guatemala, 

 Guiana, and Brazil.
