 testimony to the sueeess of onr entonioloo-ists. 



In 1906 Mr. ]\[iiir undertook an exphiration in seaix-h of 

 a parasite on the sngar-cane borer. He discovered one in 1908, 

 intreducing it in Hawaii two years later-. Sneli was the siic- 

 eoss iu breeding and establishing this parasite that the eane- 

 borer pest has decreased to a very considerable extent, the 

 sugar yield on atfected plantations greatly increasing, and the 

 losses, which for years had been large, have been niiuiniized. 

 Practically the same procedure was observed with reference 

 to the Anomala beetle, which was affecting some Oahn plan- 

 tations, the importation of a predatory wasp liavini: -n far 

 controlled the situation. 



There are many other achievements in economic entomology 

 in which prominent active members of onr society might be 

 mentioned. There are the introductions, by Professor F. 

 Sylvestri, 1). T. Fullaway and J. ('. I5ridw(dl, of fruit-Hy 

 ]iarasites from Africa and India. In 191:1 it was very diffi- 

 cult to secure Hawaiian-grown fruit and cucui'l)its that were 

 not affected by the fruit-fly, but now we are enabled To enjoy 

 a good percentage of these. Mr. 11. T. ()sl)orn discovered a 

 parasite on the corn leaf-hop] )ei'. in the Philippines, which 

 was introduced into Hawaii and lucd and distributecl by 1). T. 

 Fullaway. This ])est is now being very effectively reduced. 

 ]\rany parasites on scale and other insect pests affecting agri- 

 culture and horticulture have been searched for, discovered, 

 and introduced into Hawaii by many mendiers of onr society 

 iu their several official ca])acities. Many of these beneticial 

 insects ha\'e ])roven of a])])reciable value to the Terriloi'\- as a 

 whole. 



In a genei'al way the soeiciy has dei'ived iinudi benefit
