Pest
Undesirable organism that injures humans, desirable plants and animals, manufactured products and natural substances
Four main groups of
... [Show More] pest
1. Weeds (Ex. Canada Thistle Flower)
2. Invertebrate animals (Ex. Paper wasp)
3. Pathogens (Ex. Hawthorne rust)
4. Vertebrate (Ex. Rock dove)
Importance of pest identification
Misidentification leading to pest control failure
Understand signs of what type of pest is present
Pests change throughout life cycles
Habitat, environmental conditions and time of yea
Six general pest management methods
1. Biological
2. Chemical
3. Cultural
4. Genetic
5. Mechanical/physical
6. Regulatory
Biological management method
Introducing pests with natural enemy to maintain balance in the ecosystem
Chemical management method
Involves using naturally derived and/or synthetic chemicals to manage pests
Cultural management method
Practice that reduces pest establishment, reproduction, dispersal and survival
EX mowing, irrigation
Genetic management method
Plants and animals breed or resist specific pest problems through passing of genetic material down to form a hybrid seed or characteristics
Mechanical/physical management method
To kill pest directly or destroy their environment
Regulatory management method
Pest who are seriously endangered public health or can cause a wide spread disease
eradication and quarantine
Integrated pest management (IPM)
A balanced, tactical approach to pest control
Anticipates in pest outbreaks and prevention of pest damage
Five benefits of using IPM
1. Helps to keep a balanced ecosystem
2. pesticides can be ineffective
3. IPM can save money
4. IPM promotes a healthy environment
5. IPM maintains a good public imagination
How can one or more control options improve pest control?
Prevent resistance build up, certain pest are not affected by some forms of control
Why do pesticides fail?
1. Dosage
2. Correct use
3. Application timing
4. Application equipment
5. Environmental conditions
6. Pesticide degradation
Importance of a pesticides mode of action in managing pesticides resistance
Specific modes of action can rapidly lead to the development of resistant pest populations even after limited use in the field
Two tactics that will minimize the development of pesticide resistance
1. New or altered pesticides
2.Applying pesticides over limited areas reduces the proportion of the total pest population exposed to the chemical
Explain how pest population levels trigger control procedures
The population must be large enough to cause significant damage to justify cost control.
Economic threshold: pest population density at which control measures are needed to prevent the pest from reaching the economic injury level [Show Less]
