destruction in winter is mentioned, and emphasis is placed upon the need for rigid

 even in as simple a parasite problem as the boll weevil presents. A list of 

 parasites and predators is given.

The cotton boll weevil is eaten by the plover, killdeer, and other birds. The 

 damage which birds may cause is insignificant compared with the good they do in 

 controlling insect pests.
