There are two kinds of animal parasites affecting grain, as 

 mentioned before. One attacks the grain during growth and 

 development, the other the cured grain. Thus, the ear of 

 corn is attacked by a worm, and wheat, rye, and oats by the ear 

 cockle, another kind of round-worm. 



The insects attacking cured grains are the Tenebrio forma. 

 The larva of the Tenebrio of grain destroy the grains, reducing 

 them to a powder. Certain acari also destroy grain, among 

 which are the Gamasus and Argas. (See Fig. 104, /, g, h.) 



The acari (Fig. 104, e) reduce the grain content to a powder, 

 consuming a part and contaminating the balance with their 

 excrements and destroying it. 



Birds are capable of eating many kinds of insects and worms, 

 and while some of these when ingested by other animals suffer, 

 it is not proved that they are harmful to birds.
