BEST CO pS PY AVAILABLE By the direction of DASG a medical entomological survey was conducted on selected coral islets of the Enewetax Atoll to determine all real _and potential entomological problems to be encountered during cleanup operations. b. — Biologically and ecologically the islets are still evebyving-andrepresent a fragile and unstable biological commmity. » The introduction of higher animal life forms has been artificial. This situation has allowed a number of species to inhabit the islets unchecked by natural i . X predation. c. A variety of factors have successfully limited the tlc establishment of various pests. , 1) Limited accessability of the islets. 2) High winds. 3) d. - FC Limited land area, breeding sites, appropriate food sources and , bso harborage. These factors have, for the most part, restricted the establishment of medically important arthropoda on the islets. B METHODOLOGY: a. A total of 12 islets were selected for surveillance. Selection was based on the following criteria: 1) Size. 2) Vegetation and structural harborage. 3) Operational aspects related to cleanup mission, 4) Information provided by Mid Pacific Marine Laboratory civilians and natives.
