The wasps normally are not aggressive and do not seek out or
attack people. The sting is in accordance with most polistene —
type stings with a wheel-flair reaction and pain lasting from_
ten - twenty minutes. ‘En Masse’ attacks were not reported co
hattam
although some people recalled being stung 4 or S times. One:
-'
report of 20 stings could not be confirmed and is considered
4
unlikely. It should be noted that aggressive reactions were 2 pees
only noticed when the integrity and safety of the colony or =:
nest was directly threatened.

No mosquitoes were collected thoush light traps, natural and artificial
nesting stations were used.
Furthermore, interviews indicated no one
has been bitten by a mosquito.
High winds are the major factor
restricting the establishment of mosquito populations.
Spiders are present throughout the atoli's islets.
.
Specimens of what
appears to be the black widow have been collected by personnel of
the MPML though none were found during this survey. The only island
reporting the collection of L. mactans is Enjebi (Jane). Specimens
have been sent to the Bishop Museum, Hawaii for confirmation. No
other venomous spiders have been reported from or collected from the
islets.

Snakes are not present on Enewetak Atoll.
Flies affecting man apnear limited to several species of the genus
Musca or house flies and sarcophaga (flesh flies}.
In most cases the
breeding areas are in andaround waste disposal sites. Populations are
small and of nuisance value. Some transmission of enteric diseases
is possible though not likely.due to good sanitary practices and
structural integrity of buildings.

RECOMMENDATIONS :
a.
The rodent populations require control of the earliest possible date.
Baiting with zinc
phosphide is the most acceptable to this writer.
other baits are Rai table
A snecial annex to this report will be
However
prepared with specific guidelines on baiting requirements.
|
Bait stations containing zinc phosphide in a formulation acceptable to
the rats should be used.
Several prebaits should be tested without the
presence “of zinc phosphide to determine which is the most acccptable
to the rats. Upon comletion of prebaiting the actual zinc phosphide
bait should be employed. Each islet should be prebaited immediately
prior to baiting.
