months from October to March would destroy many of the hiber- 

 nated weevils. 



To deprive the mango weevil of its food in any particular 

 locality for two seasons would mean its extermination in that 

 locality, and could re-invasion be prevented., it would further 

 mean freedom from injury to future crops. An act worthy of 

 the attempt would be to destroy for a period of two years all the 

 fruit in the infested district after first making a careful survey 

 of the distribution of the weevil. Neglected trees in deserted 

 places and along the wayside could be cut down. All the com- 

 mon varieties could be cut back for in-arching or grafting with 

 the finer varieties. The finer varieties, of which not a great num- 

 ber are under bearing, could be allowed to fruit and the fruit or 

 refuse seeds destroyed. Certain trees should be left to fruit 

 throughout the infested district to act as "bait" for the weevils. 

 These trees should be under the control of inspectors and the 

 fruit gathered and destroyed after the weevils of the previous 

 season's brood had completed copulation and oviposition. 



The limited time of the writer has been devoted almost entirely 

 to the life-cycle and habits of the pest, necessary information on 

 which to base methods of control, and concerning which practi- 

 cally nothing could be found. Another season's observation will 

 be necessary- to advance more definite advice on the control of 

 this insect enemy of the mango.
