    Study Notes

    Insect Characteristics and Success

    • Insects' ability to thrive in diverse environments and overcome challenges ensures their continued dominance.
    • Key factors contributing to their success:
      • High reproductive capacity
      • Small size
      • Versatile exoskeleton
      • Diverse respiratory systems
      • Wings for dispersal
      • Complex life cycles
      • Remarkable adaptability

    Insect Morphology and Physiology

    • Insect mouthparts:
      • Chewing mouthparts (cockroaches, beetles): strong mandibles for tearing and chewing solid food
      • Piercing and sucking mouthparts (mosquitoes, butterflies): labium forms a proboscis, stylets pierce and extract fluids
      • Sponging and lapping mouthparts (houseflies): retractable proboscis with a spongy labella for sponging up liquid food sources
    • Ecdysis (molting):
      • Process of shedding the exoskeleton to accommodate growth and development
      • Insects have an open circulatory system, which is simpler and more efficient for their body size

    Insect Behavior

    • Action-reaction stimulus:
      • A fundamental principle in insect behavior
      • Involves a relatively automatic response to a specific environmental stimulus (e.g., visual, chemical, physical)
      • Examples: predators and parasites, habitat manipulation, cultural practices, chemical control
    • Complex, learned behaviors:
      • Differ from action-reaction stimulus in that they are not preprogrammed and instinctive

    Insect Control Agents

    • Occupational risk factors associated with pesticide exposure:
      • Pregnant women (1st trimester)
      • Field workers entering sprayed fields before re-entry interval (REI)
      • Residuals on skin and clothes
    • Mitigation strategies:
      • Pregnant women: avoid working directly with pesticides
      • REI adherence: follow recommended re-entry intervals
      • Proper PPE: wear appropriate personal protective equipment
      • Hygiene practices: wash hands and shower after handling pesticides
      • PPE maintenance: regularly clean and maintain PPE
