INTEGRATED INSECT AND RODENT PESTS MANAGEMENT 122
The management of insect and other (e.g., vertebrate) pests in organic agriculture viewpoint
is comparable to integrated pest management (IPM) in many aspects. Both employ an
intelligent manipulation of insect pest population using a combination of possible techniques
in consideration of natural regulatory factors to reduce economic damage and avoid unwanted side
effects. However, one may decide in IPM to use pesticide if it is warranted as a control option. In
contrast, crops in organic agriculture are protected by carrying out appropriate management options,
which exclude use of synthetic pesticides and genetically modified organisms (GMO). Thus, this
section consists of exercises on organic farming, which relies chiefly on: mechanical or physical
(e.g., use of yellow or sticky traps, handpicking, mechanical cultivation); cultural (e.g., crop rotation,
careful farm design to achieve desired biodiversity and integration); and biological control (e.g., use
of parasitoids, predators, insect pathogens) options. Again, appropriate exercises from Field Guide
of Discovery Exercises for Vegetable IPM (Volume II) 123 were adapted in this section.
In a previously concluded intensive one-month Refresher Course for Trainers of IPM in Crucifers
and Other Highland Vegetables 124 , the participants agreed that design of discovery-based exercises
on insects and other pests and natural enemies must start with field walks, observations, and
collection of live specimens (including plants exhibiting damages) in vegetable fields. Sorting and
identification of collected insects, other pests and their natural enemies by participants will then
be conducted in small groups. Eventually, validation of output in big group with assistance of
technical experts would follow and the participants, together with technical experts, will summarize
the activity by classifying collected specimens as follows 125 :
