a parasite which has been introduced there some years ag"o, but 

 which, so far as is known, has not become estabhshed. This 

 particular ])arasite was supposed to attach itself to a s])ecies 

 closely allietl to our local melon fly {Daciis ciiciirhitar ) and it has 

 been said that it would incidentally attack the Mediterranean 

 f ruitfly ( Ceratatis capitata ) . Efforts are beini^ made by this de- 

 partment to secure a colony of this particular parasite for ex- 

 perimental purposes, but it is doubtful whether it can be obtained 

 from Australia for the reason above stated, viz., that, so far as is 

 at present known, it never established itself under natural condi- 

 tions. On this point I expect to hear definitely in a month or 

 1110 re. 



This department continues to receive the coo])eration of the 

 U. S. Experiment Station and has concluded arrangements with 

 Dr. E. \'. Wilcox, its director, that all parasitic material re- 

 ceived from the fruitfly and cotton bollworm campaign shall be 

 solely handled by his entomologist. 



Air. Weinland, the agent of the California State horticultural 

 commission, continues to cooperate with this department in its 

 present campaign. Besides assisting in the inspection of fruits 

 intended for export, he is devoting much time to "trajiping" and 

 poisoned spray experiments. Mr. Weinland also keeps himself 

 informed as to fruitfly conditions in general on Oahu. 

 Respectfully submitted,
