Re: Mosquito Control 1972, California Field Tests.

Purthor to the Proposed intensified ground control program for Port
Coquitlam and District of Coquitlam this season, I hava been able to
obtain a quantity of chemicals that will be extremely useful in the

series of investigations by the Simon Fraser Health Unit in conjunction
with this program.

Through the co-operation of a local repreaentstive of imperial O11 of
Canada, we will receive severgl drums of Flit NLO for test purposes.
This material was prepared and researched in the United States by ’
Humble O11 Itd. As a mosquito contro] larvacide, it has been effective

against the two insecticide resistant species of mosquitoes in Calif
ornia. Information of Flit MIO is enclosed. ‘

I have also corresponded with the Zoecon Corporation in Palo Alto,

purposes. J have been fortunate in that ths convany has expressed an oe
interest in having this material researched lecally. ‘The project

manager of Zoscon has offered a quantity of a psrticular JH mimic

(2R515) for studies through the Simon Fraser Health Unit this summer,

A basic information sheet explaining the general mechaiics of ZR-S15
is enclosed.

With Flit MiO and ZR-515 rates of application
are most critical. It is most important that materials of those tynes
are used properly if they are to be effective, more so than with present
larvaciding procedures, (and jarvaciding is, at best, a difficult
operation). For this reason, it would be edvisable and beneficial to
our investigations locally if these chemicals and their rates of
applications (4.0. over various types of foliage and with v:

climatic conditions); the timing of application (the critical period);
and the resulting expected effectiveness, could be studied first-hand.
