to the spread of C. sordidus in the banana- growing districts of the 

 AVest Indies and Central America, and thus seriously affect the price 

 of one of the greatest fruit commodities of the United States. 



Owing to the feeding habits of this pest, there is only one successful 

 method of control, which is by grubbing out and burning the infested 

 stools or suckers entire. Burning, which in the ordinary sense is 

 inpossible with plants of this type, may be effected by spHtting the 

 plants and subjecting them to the heat of a powerful foundry- type 

 blast torch that quickly chars the outside and heats the fleshy 

 interior to a temperature sufficient to kill any larvae that may be 

 present. 



The wide distribution of C. sordidus in all parts of the world where 

 the banana is grown is due to the fact that the weevil spends the 

 greater part of its existence in the fleshy root-crown and that with the 

 exception of a few seeded varieties, the banana is propagated by means 

 of suckers, which are themselves the seat of infestation.

The best time to sow wheat in central and eastern Kansas is often 

 determined by the Hessian fly [Mayetiola destructor], the presence of 

 which can be easily detected by examining the wheat stubble. If 

 present in abundance, there are two effective and practical ways of 

 preventing its causing injury to the following crop. One is to kill 

 the pupae in the stubble and in self-sown wheat before the flies can
