TRAPPING AS A MANAGEMENT STRATEGY FOR
SOIL-INHABITING PESTS OF ORGANICALLY-GROWN
VEGETABLES
BaCKGroUND aND raTIoNalE
Attracting insects to a trap has been a successful concept
for insect control. The trap may contain non-pesticide
baits such as sex attractant or an attractive food source for
insect pest. In some cases, traps also serve as mating and
egg laying (oviposition) sites 136 . Farmers in the Cordilleras
commonly use trap materials to collect some soil-inhabiting
pests of organic vegetables. For cutworm caterpillar, a
simple and effective method is using traps in form of light

slabs of wood, plywood boards, or even large leaves which are placed on ground around plants in
late afternoon. Cutworms seek refuge under these slabs where they can be easily collected when
sun rises the following day. These materials are also effective in trapping garden snails and slugs.
Many innovative organic vegetable farmers had tried other trap materials that are more readily
available in their areas. In FFSs, these experiences must be shared among farmers to improve their
current best practices in using trap materials. To enhance the learning process, this participatory,
experiential, and discovery-based exercise was designed.
How long will this exercise take?
• Thirty minutes to one hour for field walks, observations, and interaction with farmers; and
• Thirty minutes to one hour for hands-on and brainstorming session.
learning objectives
when is this exercise most
appropriate?
ɶ In FFS, TOT, and VST
sessions, when there are
early infestation signs of
soil-inhabiting pests in
learning field; and
ɶ When farmers want to
learn from other farmers
their innovative practices
in using trap materials
for soil-inhabiting pests
of organically-grown
vegetables.
• To make participants aware of and understand the role of trap materials in management of soilinhabiting
pests of organically-grown vegetables; and
• To learn from other farmers their innovative practices in using different trap materials for
management of soil-inhabiting pests of organically-grown vegetables.
