the district club appeared alive tti the fact that they would have to 

 take iireventive means to stop an overproduction oi the fly. 

 ( )\vinij^ to the nature of the ground, which is mostly disintegrated 

 "aa." it is hardly possible to do any systematic clean culture work, 

 but there is no reason why the spraying and trapping luethod 

 should not be carried out with some success, if properly attended 

 to. Kona's coffee is grown in fairly large and uninterrupted 

 areas, and therefore the spraying could be done by each small 

 planter and by others interested on a commercial scale and with 

 less difficulty than in other sections on the islands. 



I'uthcrmore. the berries are in most instances pulped at cen- 

 tral mills and the pulp pile can be treated with lime or acid and 

 an enormous ])ercentage of maggots destroyed, it has not been 

 demonstrated to what extent the coffee berry or the bean is dam- 

 aged by the maggot. Apparently it does no particular harm, but 

 it would be rash to finally conclude that such is the case. The 

 question involves a series of experiments by both chemist and 

 plant ])ath()logist. During this visit I was accompanied by Mr. 

 1). l'\dlawav of the U. S. Experiment Station, and both of us 

 had several conferences with the Kona Control C\)mmittee, look- 

 ing to the further organization of artificial methods of control to 

 suit conditions in that district. 



I am indebted to Dr. Wilcox and Air. l''ullaway. both of the 

 U. S. Experiment Station, for official courtesies and cooi)eration 

 rendered in the control work during the past month. The office 

 also extends its thanks to Mr. G. Wilder for samples of infested 

 fruits used for laboratory purposes.
