Pineapple borer from Jamaica, showing larva and damage to fruit. 



some contend is confined to the ratoon crop — the plant pines not 

 being attacked; this point, the entomologist remarks, must be 

 looked into. The exact nature of the injury to the pineapple — 

 fruit and plant — may be best gathered from the following ex- 

 tract from the report of the entomologist : 



1. Attack Upon Fruit. 



a. Upon the pineapple just developing, initial attack is in- 

 dicated by exudation of pinkish jelly which coagulated in beads 

 or groups of beads. 



b. The opening of the burrows of the grub may be indicated
