** Attention Valued Customers,
In February 2012, we made a minor modification to our amphibious emergence trap. The supporting frames of re-modeled traps are much stronger structurally. The netting part of the new trap, however, is almost almost identical to the old model. Please note this change before making purchases.
One purpose of emergence traps is to estimate population densities of insects. The trapping techniques of many emergence traps, however, involve in frequent visits to remove insects trapped inside.
Our amphibious emergence trap is basically a floorless, closed tent plus a collecting head and a collecting bottle. It covers a ground surface area about 1 by 1 meters. Because the collecting system of this amphibious emergence trap adopts the design used in our SLAM traps (Sea, Land, and Air Malaise trap), it can be left unattended for a long time and the removal of caught insects is simple.
The amphibious emergence trap is easy to assemble and is highly portable. When using it as a soil emergence trap, simply place the trap over selected survey spot. About 110-cm tall, this trap provides enough height to cover small shrubs or potted plants. Use dirt to cover the flaps around the base of each side to keep inside all insects emerging from soil. Each trap has two large dome-shaped openings for easy access to the interior. In windy conditions, use tent pegs to stake down loops at the four corners.
One unique feature of our amphibious emergence trap is its ability to go aquatic. By connecting ordinary 2-L soda bottles (not included) and our special trap floating kit (sold separately), this trap can be transformed into a floating emergence trap for use in wetlands.
