INSECTS INJURIOUS TO CEREALS 239 



Methods of control. — The insect is amenable to the 

 same methods of control described for the control of the 

 flour-beetles, meal moth, and others of similar habits. 

 As in the case of the other species, so with the saw-tooth 

 grain-beetle, the attempts at eradication must be thorough 

 and persistent.

THE ANGOUMOIS GRAIN MOTH 



Sitotroga cerealella 



The Angoumois grain moth (Fig. 72) is a European insect 

 first reported as destructive at Lucon, France, in the prov- 

 ince of La Vendee in 1736. Shortly afterwards it was 

 found destroying grain in 

 the adjacent province of 

 Angoumois, from which it 

 received the name that has 

 always clung to it. Early 

 in the history of the 

 American colonies it was
