Study Notes

Insect Classification

  • Coleoptera: Includes beetles and weevils; their larvae are known as grubs, borers, or rootworms; undergo a complete life cycle.

  • Dermaptera: Commonly referred to as earwigs; they exhibit an incomplete life cycle.

  • Diptera: Encompasses flies and midges; larvae are referred to as maggots and leaf-miners; complete life cycle is observed.

  • Hemiptera: Known as true bugs, including bed bugs and stink bugs; they have an incomplete life cycle.

  • Homoptera: Features aphids, scale insects, whiteflies, mealybugs, leafhoppers, and spittle bugs; these insects also have an incomplete life cycle.

  • Hymenoptera: Covers ants, bees, wasps, and sawflies; they undergo a complete life cycle.

  • Lepidoptera: This order comprises moths and butterflies; larvae are called caterpillars, hornworms, armyworms, and cutworms; complete life cycle is present.

  • Neuroptera: Contains lacewings and fishflies; these insects have a complete life cycle.

  • Orthoptera: Consists of grasshoppers, crickets, and cockroaches; they display an incomplete life cycle.

  • Thysanoptera: Commonly known as thrips; they also have an incomplete life cycle.

Environmental Factors Influencing Insect Development

  • Temperature: The most significant factor affecting insect activity; heat units and degree days can forecast insect life stages.

  • Humidity: Refers to water vapor in the air; many insects are adversely affected during dry spells.

  • Rain and Wind: Heavy rainfall can threaten insect survival; this environmental factor is vital for the dispersal of insect populations.
