Presentation Transcript

  1. Order: Hymenoptera • Ant, bee, wasp • 2 pr wings, membranous • Social and solitary • Most larvae legless

  2. Bee Castes Worker Queen Drone

  3. Communication Dances • Round Dance • Close food (<80m in Carniolan bee) • Livelier = better source; also tells smell and taste • Waggle Dance • Further food (>80m) • Tells direction, distance, abundance, smell and taste • Sickle • Intermediate form in some races of bees (Italian)

  4. Waggle Dance Shall we Dance?

  5. Benefits of Uniramians • Food for other animals • Edible by us (except U.S.??) • Produce useful products (silk, medicine, etc.) • Detrivores/scavengers • Parasitize insects harmful to crops

  6. Benefits of Uniramians • Pollination • 1/3 of all food, spices and condiments • Beverages • Fibers • Medicines • Fats and oils $20 billion annually in U.S. alone!

  7. Look at 1 species: Honeybee • Role as a pollinator • 2.5 million honeybee colonies rented annually in U.S. for 90 crops • Products Produced • Honey - Royal Jelly • Propolis - Bee brood • Wax - Mead (fermented honey water) • Pollen

  8. Group Activity • Make a Concept Map of the Honeybee

  9. Detriments of Uniramians • Spread of disease – mosquitoes, lice • Destroy property – termites, booklice • Parasites of plants or animals • Poisonous or painful bites • Destruction of food crops

  10. Insect Venom • Honeybee – stinger is modified ovipositor • Pulled out when bee stings mammal • Bee dies • So which castes sting? Schmidt Sting Index

  11. Honeybee Venom • Venom – 40+ chemicals • Melittin – 50%  pain • Hyaluronidase – 3% opens spaces for venom to enter • Phospholipase A2 – 15%  hydrolyzes phospholipids • The major allergen • Apamine – 3%  Neurotoxin; muscle tremors • Mast cell degranulating peptide – 2%  histamine release in wasps or other species • 27% other (Histamine, etc.)

  12. Ant Venom • Contain high concentrations of alkaloids • Piperidines (Fire Ants) • Pyrrolidines • Pumiliotoxins • Formic Acid (Formicinae ants)

  13. Other venoms • Centipedes • Geophilida – secrete cyanogenic compounds • Very effective against ants and spiders • Scolopendrida – mix of stuff to paralyze or kill • Millipedes • Benzoquinones, Hydrogen cyanide, etc.
