MALE AND FEMALE HAIRWORMS 



The genus Agameris contains some of the larger species of hairworms. The average 

 length of the females of Ag. dccandata (bottom) is nearly eleven inches; that ot the 

 males (top) is not quite three inches. Many nematodes are parasites, and nearly every 

 kind of plant and animal is an actual or potential host for one or more species of them. 

 Nematodes are not immune from attacks by their own kind; in some cases they even prey 

 on individuals of the same species, something very unusual among anything but human 

 parasites. Their parasitic habit gives nematodes great economic importance Some species 

 are a serious menace to crops and herds, while others prey on our most dangerous msect 

 pests and offer a promising means of combating them.
