Abstract
Three major parasitoids of Bacrocera papyae (Drew) were recorded in papaya , Biosters vandenboschi, B. longicaudatus and B.arisanus.Relationships between total initial hosts ( B.papayae immatures ) and total hosts killed by each parasitoid species good correlation and parasitoids relationships were not density dependent. The percentage of the larvae that survived through fruit factors was 84.2% in soil, the soil factors reduced survival to 21.3%, amongst the soil, weather accounted for 45.5% biotic factors 16.5 and physical factors 2.5%.While predator ant ( Dolicholderus and Componotus sp. ) 19.1% of mortality.
