- 4. Solitary Wasps Mason Wasp on Plumrosa Characteris4cs ≒ Normally - do not sGng ≒ Do not live in social aggregaGons - solitary ≒ Bene鍖cial by being pollinators ≒ Bene鍖cial by consuming pest insects ≒ Key to ecological balance in predator/prey relaGon
- 6. Mason Wasp nest in unoccupied mud dauber nests, Carpenter bee hole nests, vegetaGon holes, and wood drillings ≒ Work bench hole used for nesGng, then paralyzed caterpillars are inserted along with an egg ≒ A month later the Wasp emerges from the sealed nest ≒ No nurse-feeding required
- 11. Braconid Wasps ≒ Cabbage Aphid, Brevicoryne brassicae, aOacked by a parasitoid wasp, Aphidius spp. by buglogical control ≒ 1700+ species in N. America ≒ Size less that 遜 inch ≒ This family of wasp parasiGzes cabbage worms, cutworms, corn earworms, gypsy moths and many other caterpillars David Cappaert (www.forestryimages.org)
- 12. Chalcid Wasps ≒ Trichogramma species of wasps are specialist parasites that target insect eggs ≒ Size range (0.02 0.31 inch) ≒ ParasiGze wide range of insects and insect eggs (200) ≒ Other Members of Chalcidoidea parasiGze caterpillars to 鍖ies to true bugs to web worms ≒ Amazon sells this most popular bene鍖cial 12,000 for $7
- 13. Ichneumon Wasps ≒ Hosts are caterpillars, wood- boring grubs of beetles, and other insects. ≒ Many females have long noGceable ovipositors ≒ Size very small to 1.5 inches ≒ Megarhyssa macrurus is ~2 inches long but ovipositor is 4 inches long. Found on dead oak trees infected with the siricid wood wasp larvae
- 14. Sphecid Wasps ≒ Astata occidentalis with captured prey sGnk bug ≒ Genus preys on sGnk bugs and lea鍖ooted bugs, adults and nymphs ≒ Ground nesters in sandy and hard packed soils ≒ Also known as digger wasps Howard Evans (www.insecGmages.org)
- 15. Cerceris Wasps ≒ NaGve wasp that is used to monitor presence of metallic beetles in Louisiana (Emerald Ash Borer) ≒ Capture beetles from wasps around open 鍖elds, ball parks, etc. to monitor EAB. ≒ Cerceris fumipennis Tom Murray (bugguide.net)
- 16. Thread-Waisted Wasp ≒ Prey on a variety of beetles that destroy trees and 鍖owers ≒ They are parasiGzed by velvet ants which eat thread-waisted larvae ≒ www.toledo-bend.us ≒ Sand Wasps or Thread- waisted Wasps Whitney Cranshaw Ammophilia spp.
- 18. Design for Solitary Wasps ≒ Plant nectary and pollen sources Flowers Power! ≒ Tolerate a low level of pests ≒ Have full season blooms from spring to fall ≒ IdenGfy favorite 鍖owers for solitary wasps ≒ Farming with NaGve Bene鍖cial Insects by Xerces Society
- 22. Farms Borders and Riparian Zones ≒ NaGve Perennials provide less labor ≒ A wide variety of 鍖owers provide diverse bene鍖cial insects ≒ Undisturbed riparian zones provide habitat and overwintering areas for bene鍖cials Xerces Society, Farming with NaGve Bene鍖cial Insects
- 23. Gardens ≒ Design to target speci鍖c pests ≒ Alyssum brings in hover 鍖ies and parasiGc wasps ≒ Therefore plant Alyssum next to leOuce that is suscepGble to aphids
