The College Of Hawaii scientist
found the work in Fiji very interest,"

the southern island before they were
Matched, in yials. and they kept
emerging from the tima he left until
about two weeks after his arrival.
Four cages were built in Fiji and ust d

cd It is now believed that the fly
will be successfully introduced In
Fiji and that its introduction will
check the cane-borer as it did here.
Another interesting point establish
ed by DR.. Illingworth is that the flies
will show renewed yigor when new
cane Is given them upon which to
operate. In one cage the flies, after
working on cane for some time, were
dormant, but when fresh cane was
put in the cages, full Of the borere
holes, the flies apparently took new
lease of life and showed great acti-I

Natures HSwat the Fly
Sometime ago the Start Bulletin pub
lished a report from the Fiji Times
to the effecfthat DR.. Illingworth had
found that the little brown ant is D
deadly enemy of the troublesome
house-fly and DIR. Illingworth confirms
this. He gives some interesting de
tails of his studies In Fiji. He says
that Hawaii undoubtedly benefits q
great deal by the presence Of these
ants. and that they are a mighty fac
tor in keeping down the mischiev0us
house-fiy. The ants not only destroy
the flies in the egg and larya stages,
but even attack the matured insects
and, by the force of numbers and
energy, cut them to pieces.
