Communication Dances

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
Benefits of Uniramians
• Pollination
– 1/3 of all food, spices and condiments
– Beverages
– Fibers
– Medicines
– Fats and oils
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
Group Activity
• Make a Concept Map of the Honeybee
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
Insect Venom
• Honeybee – stinger is modified ovipositor
– Pulled out when bee stings mammal
– Bee dies
– So which castes sting?

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