3 Curriculum Tools – GLVWG Video Limitations of power point and bulletins (size, movement)

4 Curriculum Tools– GLVWG Video Limitations of power point and bulletins (size, movement) Stakeholders could return video to review information Use by stakeholders (Extension Educators, State Specialists, MG’s) in their programs Travel budgets (video accessible online) Multiple experts across region provide training together Show “live” specimens year-round and demonstrate habitat management practices

5 Curriculum Tools – GLVWG Video Script writing and revision (Spring 2011) Video shoot (Summer 2011, both lab and field) Production (Fall 2011) Release of 25 minute video (Winter 2011)

6 Curriculum Tools – GLVWG Video Diverse Cast of Characters… Mantodea (Mantidae) Coleoptera (Coccinellidae, Carabidae) Neuroptera (Crysopidae and Hemerobiidae) Hemiptera (Anthocoridae, Nabidae, Pentatomidae, and Reduviidae) Diptera (Cecidomyiidae, Syrphidae, and Tachinidae) Hymenoptera (Braconidae, Ichnumonidae) Araneae (Araneidae, Lycosidae, Thomisidae)

7 Curriculum Tools – GLVWG Video First 17 minutes of video focus on NE groups Still and action shots! Identification, basic biology and life cycle, prey consumed

8 Curriculum Tools – GLVWG Video Video also features GLVWG members discussing habitat management Mulching Strip Tillage Selective Insecticides Polyculture Annual Floral Strips Perennial Habitats

9 Curriculum Tools –Specimen Boxes Specimens: 1. Green Lacewing 2. Hover Fly 3. Pink Lady Beetle 4. Damsel Bug 5. Ground Beetle 6. Spined Soldier Bug 7. Hover Fly Larva 8. Lady beetle Larva 9. Parasitoid Wasp 10. Lacewing Larva 11. Multicolored Asian Lady Beetle 12. Insidiosus Flower Bug 13. Brown Lacewing Celeste Welty constructed 50 individual specimen boxes for use in workshops composed of field collected, purchased, donated arthropods
