Field Guide of Discovery-based Exercises for Organic Vegetable Production
• Thirty minutes to one hour for field walks, observations (e.g., presence of egg masses, larvae,
adults, damage symptoms, and other signs of presence), and interaction with farmers on
occurrence and severity of numerous insect pests including leafhoppers, planthoppers, aphids,
and many soft-bodied insects infestation on organically-grown vegetables in learning and
adjoining field;
• One to two hours hands-on (e.g., 1 st 2 weeks before planting) on collection of Euborellia
annulata, as initial stocks, and preparation of mass-rearing equipment;
• One to two hours weekly hands-on on actual mass-production of Euborellia annulata (e.g., 1 st
4 weeks after planting);
• Thirty minutes to one hour weekly brainstorming session in processing area; and
• This exercise will require one month and two weeks from collection of Euborellia annulata
initial stocks and preparation of mass-rearing equipment.
learning objectives
• To create awareness and understanding among participants on innovative farm-level massproduction
and use of Euborellia annulata as a general predator of eggs, larvae, and pupae
of numerous insect pests as well as leafhoppers, planthoppers, aphids, and many soft-bodied
insect pests of organically-grown vegetables; and
• To learn and do farm-level mass-production and use of Euborellia annulata as a general predator
of eggs, larvae, and pupae of numerous insect pests as well as leafhoppers, planthoppers, aphids,
and many soft-bodied insect pests of organically-grown vegetables.
