FIELD
Six Meter Malaise Trap
Malaise traps usually are stretched across a stream path,
open area or other natural flyway for passive collection of
flying insects. The six-meter Malaise trap, as described by
Gressitt and Gressitt*, is several times larger than any other
Malaise trap available commercially. With its successfully
proven design, double collecting head, and large square
foot exposure, it gathers almost unlimited numbers of insects
in a relatively short period of time when properly located.
(During summer months in Florida, a trap will fill the
two collecting heads in 24 hours.)
The trap is 6 meters (19.5 feet) long, 3 meters (9.75 feet)
high, and 1.5 meters (4.9 feet) wide. It is designed to be
suspended between trees with the roof held open by ropes
tied to vegetation. The bottom is secured with stakes. The
trap can be erected by one person, and instructions are included
for set up and constructing a simple A-frame support
when there are no trees available. Frame not included with
this trap.
The trap is carefully fabricated of strong, UV resistant, 14 x
18 mesh gray polyester, reinforced at the corners. The ‘dry’
type collecting chambers are 4" diameter x 9" long, made of
clear acrylic plastic with polyethylene funnel, and clear acrylic
inner poison container. BioQuip suggests using pieces of
1196 DDVP strip as killing agent (see page 9). Sold with
complete instructions. Shipping weight is 15 lbs.

Soil Emergence Trap
This lightweight soil emergence
trap has flaps around the base
that can be covered with soil to
keep the insects inside. Loops
at four corners are provided for
the tent pegs (see #2876)
needed in windy weather. A large
dome-shaped zipper is sewn into one panel for easy access
inside the trap.
The emergence trap is made of white Polyester netting (96 x
26 mesh/square inch), with fiberglass support poles, and styrene
feet and splints. A 500 ml Polyethylene collecting bottle is
included. Weight is .84 lb. (380 grams).
Trap dimesions are 23.6 x 23.6 x 23.6" (60 cm cube). Weight
is .84 lb. (380 grams).

Soil Sieve Kit
Malaise Trap
Soil Analysis
Standard testing sieves are
widely used to separate and
grade soil samples. Entomologists
also find them indispensable
for successively
reducing the bulk of soil material
from which insects are
collected.
This stacked set consists of
four stainless steel screens of graduated mesh sizes, a solid
pan at the bottom, and a lid. Soil sample or forest litter is placed
in the top container, and the entire set agitated so that particles
of various size drop through and are sorted by size.
The sieve kit contains four high-impact plastic screens, 6-3/4" x
3", with wire mesh Nos. 5, 10, 60, and 230.
