A separator is a trap used to collect insects from forest debris.
They are easy to make using common household items.
- Draw string
- Glass Jar
- Trash Bag
- Ethyl Alcohol 70%
Fill the jar 1/3 full with the 70% ethyl alcohol solution. Cut an
opening at the bottom of a trash bag and fit it around the mouth of
the jar. secure the jar to the mouth with a draw string. Fill
the trash bag with your forest debris sample. Tie a draw string
around the top of the trash bag and suspend the trash bag in the air
by tying the other end of the string to a branch. Slowly the insects
will work their way to the jar at the bottom and die in the alcohol.
Pit fall Bait Trap
a plastic pail or coffee can with 2 inches of a 50% mixture of
molasses and water. Bury the pail so that the top edge is even with
the ground. Place boards on the ground perpendicular to the buried
pail. The boards should act as a guide, steering wandering insects
into the pail. Check the pail daily for insects that have fallen
into the trap.
Decaying animal remains such as lizards or snakes can also be
used as bait. When using animal remains, cover the top of the pail
with wire to keep out larger animals.
Other types of bait that might be used are decaying fruit, beef
or hog live, chicken heads and dung.
traps are a very effective way to collect insects at night. The
figure to the left shows 2 different types of light traps. Both are
fairly easy to make. The first trap shows an incandesent light bulb
suspended over a glass jar. The jar filled 1/3 of the way with ethyl
alcohol 70%. Insects are attracted to they light, hit the light
cover and fall into the funnel where they slip down into the jar.
The second light trap uses a florescent light. The sheet metal
around the florescent tube deflects the insects in flight and they
fall into the bucket. The bucket contains the same ethyl alcohol
mixture as above.
