Section 4 • Integrated Insect and Rodent Pests Management
how fast we can facilitate FFS farmer-graduates and facilitators to establish participatory
technology development (PTD) activities to get answers on the following questions: (1)
What size and number of yellow traps are required per unit area? (2) Where and when do
we install the yellow traps in potato fields? (3) What shades of yellow and materials do
we use for yellow sticky traps? (4) What complementary activities do we need for yellow
sticky traps to be more effective?
5 There is a need to drastically bring down existing leafminer population in these infested
areas to sustain effectiveness of yellow sticky traps. This will require a moratorium
in planting potato and other alternate host crops, like Chinese cabbage and celery, and
planting instead of less preferred or non-host crops, such as cabbage and carrots, in these
areas for at least two months to break the life cycle of leaf miner. Appropriate sanitation
practices (e.g., proper disposal of infested potato plant debris, alternate host crops and
weeds) should also be employed to bring down further leafminer population in those areas.
The Sangguniang Bayan of Buguias or Sanguniang Barangays of Buyakawan and Loo can
pass a municipal or barangay resolution to this effect.
5 In succeeding seasons, once leafminer population is already low, synchronous planting of
potato can be done together with early installation of yellow sticky traps in those areas to:
(1) maintain pest population at low level, (2) discourage use of pesticides, and (3) encourage
build-up of natural enemy populations. Follow-up planting of non-host crops should also
be done to break life cycle of this pest before planting potato again in these same areas.
These strategies can be well articulated in FFS follow-up and local multi-media awareness
campaign activities in leafminer infested and adjoining areas.
5 In coordination with LGUs, through the Office of Provincial Agriculturist (OPA) of
Benguet and Municipal Agricultural Office (MAO) of Buguias, Benguet, the government
technical staff should design, plan, and implement a crash FFS follow-up activities in all
infested areas as soon as possible.
4. Facilitate farmers to do hands-on exercises to compare the effectiveness of yellow sticky trap
materials as early as first infestation of leafminers is observed, as follows:
5 Install suitable yellow sticky trap materials (e.g., made of different materials and shades
of yellow colors) in early morning or late afternoon at varying distances and locations in
rows within plots;
5 Gather installed yellow sticky trap materials (e.g., at varying heights) and collect trapped
potato leafminers in succeeding morning or afternoon;
