    Pest and Their Characteristics

    Uploaded by

    Ryan Paul Caalem
    Pests include any organisms that are harmful to humans, agriculture, structures or the environment. There are four major categories of pests: weeds, invertebrates like insects and spiders, vertebrates like birds and rodents, and plant pathogens. Properly identifying the specific pest is critical to designing an effective management plan. Pest identification involves understanding the pest's life cycle, host, and characteristic signs of damage or presence. Both natural controls like weather and predators as well as human-applied controls can help manage pest populations.

     1st Step: Always identify the pest before taking
    any action!
     Become familiar with its life cycle and habits
     Use the information
    to design a pest
    management plan
     Misidentification results in lack of knowledge =
    ineffective control of the real pest
    Four Major Pest Categories
    #1 - Weeds: undesirable plants
    Four Major Pest Categories
    #2 - Invertebrates, such as:
     Insects

     Spiders and mites

     Pathogens – living agents
     Fungi
     Bacteria
     Viruses
     Nematodes
     Phytoplasmas
     Non-living agents: cold, C.R. Foss
    heat, pollutants, dog urine
    Pest Identification is Critical
     Understand that all stages of a pest

    by specialists
     Handle samples carefully
    Look for Characteristic Signs
     Birds and rodents: unique
    nests
     Insects: feeding damage
     Fecal materials are
    distinctive – insect frass or
    bat guano
     Weeds: particular flowers,
    seeds, or unusual growth
    habits
     Pathogens: unique patterns
    or growths on plant tissue
    Natural Controls

     Wind
     Temperature
     Humidity, rain
     Rivers, lakes, mountains
     Pathogens, predators
     Food supply of the pest
    Human-applied Controls
     Biological
     Mechanical
     Cultural
     Physical
     Genetic
