While it is far too early to draw any conclusions regarding the ul- 

 timate effectiveness of these introduced parasites, data for 1914 and 

 1915 show that all four parasites have successfully established them- 

 selves, and are already promising much as a factor in the control of 

 Hawaii's worst fruit pest, and form a basis for the study of the rela- 

 tionship between the parasites in their struggle for existence during 

 the years to come.
