Introduction Insect traps are an integral part
of integrated pest management systems.
Determining the number and presence of pest
insect species often determines the timing of
control measures and/or the effectiveness of the
measures employed. Traps themselves can serve as
control measures. Although insect traps exhibit
a wide variety of physical designs, most traps
are designed to use pheromones or kairomones as
an attractant and are structured in such a way to
allow for entry of insects while capturing them
in some manner. The LepTrap was designed to
serve as a versatile platform for capturing a
variety of insect species for monitoring or
control purposes. The LepTrap has a unique
design that allows for multiple plume formation,
is constructed from durable materials and can be
manufactured in almost any color. Numerous field
evaluations were conducted in 2005 with
commercially produced prototype LepTraps for
monitoring and mass trapping a variety of insect
species.

Discussion Test 1 The red LepTrap captured a
mean of 2.42 OFM/trap/day compared to 1.79
OFM/trap/day for the LPD. Test 2 The red
LepTrap captured a mean of 1.5 OBLR/trap/day
compared to 1.8 OBLR/trap/day for the wing trap
and 0.9 OBLR/trap/day for the Intercept A Test 3
The white LepTrap captured a mean of 3.0
TABM/trap/day compared to 3.0 TABM/trap/day for
the wing trap and 2.7 TABM/trap/day for the LPD
trap. Test 4 The white LepTrap captured a mean
of 0.69 LB/trap/day, significantly more (P0.05)
than the Pherocon 1C trap at 0.56
LB/trap/day Test 5 The blue, green, red, and
white LepTraps captured means of 0.93, 1.08,
0.90, and 1.00 PTB/trap/day compared to 0.79
PTB/trap/day for the Pherocon 1C trap (NS at
P0.05) Test 6 The green, red, blue and white
LepTraps captured means of 0.12, 0.23, 0.21, and
0.20 CM/trap/day compared to 0.11 CM/trap/day for
the white LPD trap (NS P0.05) Conclusions In
evaluations for monitoring a wide variety of pest
species, the LepTrap consistently captured as
many, and often more, lepidopteran pests as the
did standard commercial traps (Delta, Large
Plastic Delta, and Wing Trap). In evaluations
against codling moth and peachtree borer, there
were numerical non-statistical differences
between different colored LepTraps that warrants
further investigation with more intensive field
evaluations. The LepTrap is a versatile
monitoring device that will be commercially
available for the 2006 growing season. Acknowledg
