1. | GENERAL:
a.
By the direction of DASG a medical entozological survey was conducted
on selected coral islets of the Enewetak Atoll to determine all real
and potential entomological problems to be encountered during cleanun
operations.
b.
Biologically and ecologically the islets are still evebyinr-andrepresent
a fragile and unstable biological community. 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
predation.
c. A variety of factors have successfully limited the tle establishment
of various pests.
d.
1)
Limited accessability of the islets.
2)
High winds.
3)
Limited land area, breeding sites, appropriate food sources and
harborage.
These factors have, for the most part, restricted the establishment
of medically important arthropoda on the islets.
METHODOLOGY:
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)
S)
Information provided by Mid Pacific Marine Laboratory
Civilians and natives.
(MPML)
Information provided by engineers surveying various islets.
