Study Notes
Entomology
- The study of insects and their interactions with humans, the environment, and other organisms.
- Groups of insects with similar biology and appearance are classified together.
- More specific groups share closer biological characteristics.
- Classifying insects helps determine damage potential and pest status.
Classification System
- Organism classification has evolved over time, with systems like:
- Three kingdoms: Protista, Plantae, Animalia (1894)
- Five kingdoms: Protista, Monera, Plantae, Fungi, Animalia (1959)
- Six kingdoms: Eubacteria, Archaebacteria, Protista, Plantae, Fungi, Animalia (1977)
- Three domains: Bacteria, Archaea, Eukarya (1990).
Phylogenetic Tree
- A visual representation of evolutionary relationships between organisms.
- Branching patterns illustrate shared ancestors and evolutionary divergence.
Animalia Characteristics
- Multicellular organisms
- Organelles with a nucleus, but no chloroplasts or cell walls.
- Movement through contractile proteins: Cilia, flagella, or muscular organs.
- Obtain nutrients through ingestion.
Classification System Example
- Honey Bee (Apis mellifera) classification:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Hymenoptera
- Family: Apidae
- Genus: Apis
- Species: Mellifera
Arachnida Characteristics
- Two body parts
- Four pairs of legs
- No antennae
- No wings
Classes of Arthropods
- Arachnida: spiders, mites, ticks
- Diplopoda: millipedes
- Chilopoda: centipedes
- Insecta: insects
Insecta Characteristics
- Mandibulate mouth: mandible, maxilla, and labia.
- Three body segments: Head, thorax, abdomen.
- Pair of antennae
- Most have compound eyes.
Arthropoda Characteristics
- Exoskeleton
- Chitinous exoskeleton
- Segmented appendages
- Segmented body
- Bilateral symmetry
- Dorsal tubular heart
- Ventral paired nerve cord
Diplopoda (Millipedes)
- Diet: Fungi and decaying plants.
- Plant damage: Can damage plants.
- Legs: Two pairs of legs per segment.
- Body parts: Two visible body parts: head and body.
- Cross-section: Round in cross-section.
- Movement: Slow moving.
