- 1what are the 5 types of arachnida?Scorpionidae
Spiders
Harvestmen
Acarina
Pycnogonids - 2Characteristics of ScorpionidaeInjects neurotoxins that block Na and K channels
• Feeding – Chelate pedipalp can be used to manipulate prey, also uses sting
• Reproduction – Males deposits sperm on the ground, which is taken up by the female gonopore, so eggs fertilized inside the body
• Respiration – Book Lungs - 3What are the two main groups of spiderso Hunting Spiders
Wolf Spiders, Crab Spiders
o Cobweb Spiders
Orb Weaver, Sac Spiders - 4Which type of arachnida has poison glands that is associated with each chelicera?/spiders

- 6What species of spiders are toxic?black widow
hobo spider
redback - 7What are Acarina?Class of chilereates that are ticks and mites
- 8what are pycnogonids?seaspiders
- 9Main crustacea characteristics• 2 pairs of antennae
• Head, Thorax and Abdomen and has an exoskeleton
• Biramous appendages (2 Branches), Compound eyes
• Gut is lined with chitin, has a foregut, midgut and hindgut
• Gas exchange = Gills - 10Main reproduction basis of crustacea• Separate sexes
• Specialised appendages for mating and egg brooding
• Eggs hatch into larvae, many larval stages are possible - 113 classes of crustaceaMalacostraca
copedpoda
cirripedia - 12orders of malacostraca (crustcea phylum)Peracarida (super order)
amphipoda
isopods - 13life cycle of super order eucarida• Eggs -> Zoae -> Megalopa -> Juvenile Crabs -> Adult Crabs
- 14What are most insects classified as?• Most insects are uniramians under the Phylum Arthropoda
- 15Why are uniramians different from the others?as they have one pair of antennae, whereas the others have either none or multiple
- 16What are insect imporatnce to humansDirect resources (honey)
Ecosystem services (pollination, biological control of pest species)
Disease vectors and are pests of livestock and crops - 17What is the general body plan of insects?• Head – One pair of antennae and compound eyes
• Thorax – 3 pairs of legs, 2 pairs of wings
• Abdomen – Houses productive structures
• Reparation System -> Tracheal system
o Cuticle is lined with network of tubes
o Gas exchange by diffusion and pumping generated via body movement (Limits body size) - 18What are the two main groups of insectsentognatha
ectognatha - 19What are the properties of ectognathao Have external mouthparts
o Can be winged or wingless - 20What the differences between direct and indirect flight muscles• Direct Flight Muscles
o 1:1 relationship between nerve impulses to muscle contractions
• Indirect Flight Muscles
o Smaller insects ; Faster wingbeats
o Faster than max nerve discharge rate
o Muscles contract in response a tug and will oscillate - 21How do insects feed?Mouthparts have 3 appendages which are highly versatile and adapted for wide range of feeding modes
- 22What are insect pheromones used forpest control
- 23Why are pheromones released• Midges – Released pheromones to attract others to a blood meal
• Wasps Bees – Release an attack pheromone
• Ants – Follows a trail of pheromones - 24What is euscociality?• Specialised ‘castes’ – Individuals that have differentiated for specific tasks
