98 REPORl OF OFFICE OF EXPERIMENT STATIONS. 



The division of ent()nu)lo<2:y coutiniu'd its routine work of breed- 

 in*? and distrihutinp: parasites as a means of coiiihatinfr insect pests 

 and of inspectinir the phmtations |)eriodieally. Ktl'orts are being 

 put forth to introduce a tachinid liy from Larat, which destroys cane- 

 borer hirviv. Some diflicuUy has been encountered in this undertak- 

 ing, as the sclieme for forwarding material to a lialf way station at 

 Hongkong was not successfuL 



The division of phint pathology, in addition to the inspection of 

 all plantations, devoted its attention to a diseased forest area in Maui 

 and to diseases of pineapples. The forest disease was not found due 

 to a fungus, but the cause was attributed to chemical changes in the 

 soil, probably under the influence of bacteria. The officers of this 

 division now act as inspectors of imported plant material in con- 

 junction with the territorial officials.
