Large quantities of stored grain are annually destroyed by weevils 

 through lack of care and proper storage. Infestation may be prevented 

 by thoroughly cleaning the empty bins and spraying with a 10 per 

 cent, kerosene emulsion, and by moving and aerating the grain. If 

 it should become infested, it must be thoroughly fumigated, and for 

 this reason the bins should be well built and should be separate from 

 the barn.

This Aphid, which is dependent upon ants for travelling from one 

 plant to another, destroys the cotton plant by sucking the juice from 

 the young tap-root. A temporary means of control lies in preventing 

 the ants from establishing themselves in the spring by a system of 

 shallow cultivation, continued till the cotton is thoroughly established 

 in a healthy condition. Permanent control may be most satisfactorily 

 effected by a three years' system of rotation, the best being maize, 

 oats and cowpea hay, and then cotton. It is also of great advantage 

 to have winter cover- crops on infested land, so as to prevent the 

 growth of the winter food-plants for this Aphid, and thus reduce the 

 spring infestation.
