The
Omni-Directional Fay-Prince Trap Model 112 is
a daytime trap which is quite specific for Aedes
aegypti and Aedes albopictus adults
of both sexes; it will capture gravid and nuliparous
females. Based on the original CDC
Fay-Prince Trap, this Model 112 trap increases the collection
of females since they can be captured arriving
in any direction.
The Omni-Directional Fay-Prince Trap is
based on the Fay-Prince trap (Fay and Prince, 1970), a unit
that was specifically designed and field tested for the collection
of Aedes aegypti by
scientists from the Technical Development Laboratories of
the Communicable Disease Center, DHHS. The design was based
on the attraction of contrasting gloss black and white panels
and employs a wind-orienting cover and cylinder that
houses a suction motor and supports the collection bag or
killing jar.
With the arrival of Aedes albopictus, scientists
from the U. S. Department of Agriculture (Jensen et al.,
1994) compared a number of new and old trap designs for
their ability to collect both Aedes aegypti and Aedes
albopictus. The
trap capturing the most females of both species was a unit
consisting of 2 Fay-Prince traps mounted back-to-back and
modified so that females arriving from any direction could
be captured. The
Omni-Directional Fay-Prince Trap is a direct result of
these positive field tests.
CO2 Release
The addition of dry ice
which involves CO2 gas, results in significant increases
in the number and diversity of mosquitoes caught and
makes the location of the trap less critical.
Used in the afternoon, it allows the collection of diurnally
active mosquitoes that are not normally attracted to
light traps. Our Insulated Dry Ice Container is simply
a modified Igloo® drink
cooler with stainless steel hardware to make it easy
to use with 2kg of dry ice. The
insulation slows the rate of sublimation and by hanging
the trap from the hook below the cooler, the CO2 is released
at the correct location, right above the trap.
