Intro to Entomology Week 6 Notes  Xenodiagnosis of Chaga’s Disease  Killer bugs feed on a patient inside a controlled laboratory.  Ten days later, the researcher will look for Trypanasoma in the Killer bug’s  feces.  Xenodiagnosis: use of a live vector to diagnose a disease.  Aphids  Their mouthparts, or “beaks,” swing down.  They’re plant eaters.  Have membranous wings.  They are major agricultural pests.  Aphids  Aphids have many predators.  Aphids give birth to nymphs.  Plant defense:  sticky hairs  Aphids are usually wingless.  Overpopulation of aphids results in winged aphids.  Honeydew: a sweet, sticky substance excreted by aphids.  Honeydew Production by Aphids  Honeydew allows for water excretion.  Honeydew attracts ants that drink it.  Honeydew can cause fungal growth.  Interesting Fact: Some Bible reviewers thought that manna was actually  honeydew.  Aphids  They have piercing, sucking mouthparts.  They are tended by ants for their honeydew.  Scale insects have scales on their wings, hence their name.  Order: Coleoptera  coleo = sheath; ptera = wings  Common Names: Beetles; Weevils; Ladybugs; Fireflies  Species: 300,000  Coleoptera  Have complete metamorphosis  Have chewing mouthparts  Their forewings are hardened.  Their hind wings are membranous.  Have a thickened exoskeleton  They are pests to crops and trees.  They are the largest insect order.  Complete Metamorphosis: Egg  Larva  Pupa  Adult  Intro to Entomology Week 6 Notes  These Four Stages in Complete Metamorphosis Often Vary in:  Appearance  Habitat  Hosts they feed on  Their predators and parasitoids  Ladybugs  Ladybugs lift up their front wings and fly with their hind wings.  Ladybugs are beneficial.  Fireflies  Each species has a unique flash pattern.  Males flash to attract females.  Then, the female will flash in response.  Males and females have different flash patterns.  Some females mimic flash patterns of females from other firefly species in  order to prey on their males.  Firefly larvae are aposematic; they glow to deter predators.  Fireflies  They produce light with Luciferin, a pigment which yields light when  combined with oxygen.  98% of their energy is released as light.
