Lantern Trap and Its Parts 



Of course the percent of infested bolls in -the early pickings is 

 larger than the percent of the total number of bolls, since the 

 worm caused so many of the bolls to open prematurely. The 

 table also shows the greater liability to attack of the Sea Island 

 variety. During the season of 1912 we aim to get the benefit 

 of the annual pruning as described by doing the work all at one 

 time; in which case we hope to have an easier fight than in 1911 ; 

 yet because of more or less ornamental cotton and milo in Hono- 

 lulu we can hardly hope to start clean. l^i)on one large plant- 

 ing where the ])runing and burning was well done in 1910, — 

 we are informed that the infestation in the si)ring of 1911 was 

 very light ; but, because of the difficulty to get the pickers to col- 

 lect infested bolls, the percentage of infestation greatly increased 

 during the season. This shows what can be accomplished by em- 

 ploying the first named method and we have demonstrated the 

 value of the second and third. Other host plants than cotton 

 must always be ke])t in mind and cut down and burned ; then if 

 the grower works faithfully along the lines mentioned above he 

 may hope for some returns for his labors.
