The Mediterranean fruitfly ( Ooratitls capitata Wied. ) population level 
showed a gradual decrease from April 1931 through I93U . In 1935 there was a 
rapid increase in population level, reaching the peak in 193^. During 1937 the 
population levol started to decline and at the present tine, July 1, 1938, it 
is at about the 1932 level. Paras itizat ion records of the Mediterranean fruit- 
fly parasite ( Opius hunilis Silv, ) for the period 191^-1933 shows that, this 
species reaches its naxinun abundance during March to May. During March to Juno

specimens "being obtained. Since last October only seven specimens have been re- 
covered. These records are for the Island of Oahu.
