McPhail Traps
McPhail traps consist of two interlocking plastic sections, a clear top and an
inverted funnel bottom (Figure 4-13 on page 4-15). Fill the donut-shaped trap
bottom with water with a small amount of detergent (to break the surface
tension), or with water mixed with insecticide.
Important
It is not known whether pesticides can continue to be used in traps in this
manner. If so, the inclusion of pesticides in traps will likely depend on the
environment in which the traps are located. Surveyors should check with the
national program manager, or FIFRA coordinator, for further guidance.
Suspend a pheromone lure inside the trap. Adult males following the
pheromone plume will enter the trap through a hole in the trap bottom. Once
inside, they fall into the liquid and drown. As is the case with pan traps,
McPhail traps can capture large numbers of insects.
For further information, contact the EDP-National Survey Supply Coordinator.

Bucket Traps
Bucket traps are made of plastic and are available in a variety of colors. The
bucket is the main body of the trap and is used to collect all insects that enter
the trap. Bucket traps are roughly 21 cm high by 17 cm wide. Place the
pheromone lure inside the clear plastic cage on the lid. Place an insecticide, for
example a dichlorvos block, inside the bucket.

Attach a wire or string to the top lid to hang the trap on a pole or trap stand.
Male moths will follow the pheromone plume, enter the bucket trap, and be
killed by the insecticide. As is the case with pan traps and McPhail traps,
bucket traps can capture large numbers of insects. As such, they can be used
for monitoring as well as mass-trapping purposes. Russell IPM recommends
the use of Bucket traps in dusty areas.
