sugar planters, than which there could be no more elrtquent 

 testimony to the success of our entomologists. 



Jn 1900 Mr. Mnir undertook an exploration in search of 

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

 introducing it in Hawaii two years later. Such was the suc- 

 cess in breeding and establishing this parasite that the cane- 

 borer pest has decreased to a very considerable extent, the 

 sugar yield on affected plantations greatly increasing, and the 

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

 Practically the same procedure was observed with reference 

 to the Anomala beetle, which was affecting some Oahu i)lan- 

 tations, the importation of a predatory wasp having so far 

 controlled the situation. 



There are many other achievements in economic entomology 

 ill which prominent active members of our society might !)e 

 mentioned. There are the introductions, by Professor F. 

 Sylvestri, D. T. Fullaway and J. G. Bridwell, of fruit-fly 

 parasites from Africa and India. In 1913 it was very diflS.- 

 cult to secure Hawaiian-grown fruit and cucurbits that were 

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

 a good percentage of these. Mr. H. T. Osborn discovered a 

 parasite on the corn leaf-hopper, in the Philippines, which 

 was introduced into Hawaii and bred and distributed l)y D. T. 

 Fullaway. This pest is now being very effectively reduced. 

 Many parasites on scale and other insect pests affecting agri- 

 culture and horticulture have been searched for, discovered, 

 and introduced into Hawaii by many members of our society 

 in their several oflicial capacities. Many of these beneflcial 

 insects have proven of appreciable value to the Territory as a 

 whole. 



In a general way the society has derived much benefit 

 from the work of all our active members and has frequently 

 enjoyed the advantage of many valuable papers and observa- 

 tions contributed by them from time to time. These papers 

 have been, in most part, on subjects of our endemic insect 

 fauna, and quite naturally so, as the studies and life histories
