AGRICULTURE FOR BEGINNERS 



The places best adapted to the hibernation of the weevil 

 are trash piles, rubbish, driftwood, rotten wood, weeds, moss 

 on trees, etc. A further help, therefore, in destroying the 

 weevil is to cut down and burn all cotton stalks as soon as 

 these crops are harvested. This destroys countless num- 

 bers of larvae and pupae in the bolls and greatly reduces 

 the number of weevils. In addition, all cornstalks, all trash, 

 all large clumps of grass in neighboring fields, should be 

 burned, for these, too, furnish winter homes for the weevil.

FIG. 265. MAP SHOWING DISTRIBUTION OF COTTON-BOLL WEEVIL IN 1904 



The darker shaded area indicates the limit of the region in which the weevils are 

 to be found in all cotton fields ; the remainder of the shaded portion indicates 

 the region in which isolated colonies are known to exist
