Secondary Pests Control only under certain circumstances required
Identification Required to address a situation including:
-Physical Features
-Characteristics of damage
-Development and Biology
-Key, Secondary, or Occasional
-Control Goal
Basic Pest Groups -Weeds
-Parasites and Diseases
-Mollusks

Pathogens causing most plant and animal diseases Fungi, Bacteria, Mycoplasms, Viruses
Parasites Tick, Lice, Fleas, Bedbugs, Mosquitoes, Nematodes, Mollusks. Plants have leaf
spots
Arthropods Insects Animals with segmented bodies and jointed APPENDAGES.
-external skeleton of light but strong material chitin
- Jointed legs for walking and other specialized appendages such as antennas,
pinchers, sucking tubes, etc.
Insects -Produce large offspring numbers
-Can be difficult to identify because body changes as they develop called
Metamorphosis
Gradual Metamorphosis -Insects Develop from egg to wingless nymphs then mature adults with no pupa
stage
-Nymphs look similar to adults as they feed and grow they molt(shed) multiple times
growing larger
-grasshopper, cockroaches
Complete Metamorphosis 4 Stages: Egg, Larva, Pupa, Adult
-Larvae look very different from adult
-Larvae are active feeders and often look like worms with antennas and legs
-Pupa often cocooned
-Adult form produces eggs for next generation
-Moths, butterfly, ant, wasp, fleas
Arachnids Wingless Arthropods with 4 pairs of legs on the rear body section and no antennas
-Two body parts: Cephalothora (head and thorax) and abdomen
-spiders, ticks, mites, scorpions
Vertebrates Animals with backbone including mammals, birds, reptiles, and fish
-Become pests when they damage property, agriculture, or are a threat to human
health and safety
-Indoor control focuses on eradication of rodent pests
-Outdoor control focuses on suppressing nuisance animals
Deciding when to use pest control 1. Control only when causing unacceptable harm or damage
2. Use a control strategy that will reduce numbers to an acceptable level
3. Cause as little harm as possible to everything else
Thresholds - Levels of pest populations that trigger action to prevent the pests in an area from
causing unacceptable injury or harm.
- Can be based on appearance, health, or economic concerns.
- Threshold levels can be zero, for homes or food processing to high.
Economic Thresholds - Threshold levels are often set at the level of economic losses caused by the pest
will surpass the cost to control the pest known as economic thresholds.
