their ential to serva as 2 posquito breeding ofte. - The entire area
will be divided into five sectors. ‘Tir students will te assizned primarily
£9 ene sector for mopping and profect Pparposes,

sent will assess the water quality end determine the presence
er of aquatic end Seri-aquatic orpanici in cach cf the noted eres,

ded,

The extent of flood and seepage waters thet annually occurs throughout,
wey and dune will bo watched closely and the emourt of aor age sudiected
to these waters will te Tapped at various levels of the viver as it rises.
Tae occurrence of any aguntic organisns in the flood/seepare waters will
be neted, Approximate Lines or sequence of appsarance of theso organises
could be assessed and related to the presence of any mosquito larvae.

Onee ths oresenee of mosquito larvae has been discovered, the species will
2d. Fres this, a correletion betucen tha Zasquito species and
tyre of environment can be eoserved. The degree of infestation or
nuzbers ef larvac per unit arca (container) as well m the dates of lorvas
Occurrence and subsequent lenpth of the life cycle to adult vill be:
recorded,

Subsequent to the cceurrense of tho mosquito irvae, 4 variety of methods
of abatccent, other than through the use of pesticices, will be attenoted,

A varlety of Surfactants, including FLIT MLO will to stulied in order to
determine ths extent of effectiveness in larva) eentrol, FLIT 320 is a
low viscosity, colorless petrolew: of] and is reportedly effective to all
three aquatic life Rtaves of the roszuite. It also is Suprested to bo
safe for handling anj minixises hazards to fish and wildlife,

Investigations late possible usages of certain pathorens amt parasites
(1.9, Cosloxyces and Nezetedes) will be insorpersted in a soriss of projects

in the field. Other biological controls will b= researched in co-operation
with the Postolegy Centro, Simon Fraser University, Burnaby, B.C,

Natural ant/or Induced pretation of the larvel ant atult stares will be
ons of the major investigations, Tne Geeree of effectiveness ond results
can be assessed from cach epont or on ths whole, aa an intesrated progran,

Not all rosquito breeding sites aro restricted to land along the rivers
and thoir tributaries. In addition to actual control xeasures, this
propre will also concentrate en public education in erder to seducs

ackyerd sites (i.v, ditches, bird baths, barro's, ete.)

At the conclusion of the nropram, each atuieat will cenpile a report
Which will induce recomendations o: Sucreutions of source reduction (the
elimination of, or preventian or, waters that breed mosquitoes), Thess

areas will be reported to the Corporation of Port Cogaltlen for censideraticn,

Althouph mont methyts of ecatrols wil) be conducted by the students
through ground apolication, the use of the edrer ft wil te necessary if
or when Jarge flood water areas mike Cround epoliectien innosaitte or
impractical. Por exstiole, an area of five acres of shallow water can
be treated by all th? students Working together. Cre acre of shellow

water ray ke treated by tyo ctulents, sover, an arcsa of 30 acres of
shallow and dcep waters might be best ecntrolled shrsugh aeric? means

(particularly when considering the use of 2 Surfactant, 3 FLIT M20},

Studias of biolesical agents can also te investizoted with the distrfbution
of these rateriais ty aircraft, When or if effective blolericn? egeats
are cvailatle, one of the most efficient msans ef larga stele distribution
will be by the ciresatt., Tho Simon Fraser Health Unit will te investirating
teans of applying biolorical rattas fron the air without destraying the
agent in the process, The wark can te incorporated inte a eropran of

this sort.

In all ratters of possible interferences with fish and wildlife, the B.c.
Penartment of Agriculture, Eavironnent Canada, an? the 8.C. Tish ami

Will be forwarded to theso departments and any recomendations will be
