  1. Insect Identification for ND Agronomy CDE Insect Identification, Life Cycle, Economic Impact, and Mouth Parts Authored by: Seneca HS, AR Adapted by: Jeff Stachler

  2. What do you need to know? • Life Cycle • Complete • Egg, larva, nymph, adult • Each stage is uniquely different • Incomplete • Egg, nymph, adult • Gradual change with young looking similar to adult • None

  3. Are all specimens in the Insect Identification Section insects?? Kingdom (Animal) Phylum (Arthropoda) Class (Hexapoda / Insecta) Order (Hymenoptera) ?? Family (Apidae) Genus (Apis) Species (mellifera)

  4. Arthropod Classification • Classes (2) • Arachnida • Mites, Spiders, ticks, scorpians, other related • Hexapoda (Insecta) • Insects

  5. Arachnida • Bodies: two distinct regions • cephalothorax • abdomen • Legs: Four pairs attached to cephalothorax • Other: Lack wings and antennae • Order: Acari • Specimen: Spider mite

  6. Spider Mite

  7. Spider Mite • Life Cycle: Incomplete • Economic Impact: Removal of plant fluids • Mouth Part: • Piercing-sucking

  8. Class Hexapoda (Insecta) Insect Characteristics • Most adult insects have the following characteristics: • A body divided into three parts (head, thorax and abdomen) • Three pairs of legs • Usually one pair of antennae and a pair of compound eyes (a few exceptions to these characteristics are found) • Usually two pairs of wings (absent in many insects such as lice, fleas, ants; flies have one pair of wings)
