MODULE 5 Flashcards
What is integrated pest management (IPM)?
The blending of all effective, economical, practical, and ecologically sound pest control methods into a flexible approach.
What is the primary goal of integrated pest management?
To optimize pest control in relation to the total plant production system considering economic, social, and environmental conditions.
List the different tactics included in integrated pest management.
- Chemical
- Biological
- Cultural
- Physical
- Genetic
- Regulatory
What does IPM maintain regarding pest populations?
It maintains the population of any pest at or below the level that causes damage or loss.
What is a control method in the context of pest management?
The tactics used to kill a pest, which is part of integrated pest management.
What is the purpose of pest control tactics?
To reduce the reproductive potential of a pest population or modify its behavior.
Name the components of physical/mechanical control.
- Physical control
- Mechanical control
What is cultural control in pest management?
A method that involves altering farming practices to reduce pest populations.
What does biological control refer to?
The use of natural predators or parasites to control pest populations.
What is behavioral control?
Methods that modify the behavior of pests to reduce their impact.
Fill in the blank: Integrated pest management is a mixture of _______ used to suppress the pest population.
[control methods]
True or False: Integrated pest management can only use chemical methods to control pests.
False
What are the expected outcomes for students at the end of this module?
- Know the different control methods in integrated pest management
- Determine the difference of each method
- Apply the different control methods on their chosen crop
What is Physical Control in crop protection?
Direct or indirect methods that destroy pests or make the environment unsuitable for their survival and reproduction.
It includes various devices that exclude, entrap, entangle, or electrocute insects.
What does Mechanical Control involve?
The use of mechanical force, manual labor, and mechanical devices such as barriers.
Example: Use of nylon net to control diamond back moth, flea beetle, and cabbage web worm.
What physical factors are involved in Physical Control?
Temperature, moisture, light, and sound.
Man uses physical control where feasible, but it can be difficult in uncontrolled environments.
What are the primary actions of Physical Control methods?
Damage, kill, or induce behavioral changes in target organisms.
Direct impacts include immediate kills through mechanical shocks.
What is an important characteristic of Physical Control methods in modern agriculture?
They have attributes suitable for incorporation into Integrated Pest Management (IPM) strategies.
Technological advances have increased precision in implementation.
What is Temperature Manipulation in Physical Control?
Influencing insect activity and metabolic rate through environmental temperature.
The optimum range of temperature is vital for normal insect activity.
What are the two types of lethal temperatures in Temperature Manipulation?
- High Lethal Temperature (e.g., sun drying, hot water treatment, flaming)
- Low Lethal Temperature (e.g., cold storage)
How does Moisture Manipulation affect pest survival?
In well-dried grains (moisture content <10%), survival of stored grain pests becomes impossible.
Example: Rice weevil, pulse beetle.
What is the effect of alternate wetting and drying in rice fields?
It reduces damage from the brown plant hopper.
How does Light Manipulation influence insect behavior?
It affects their behavioral orientation.
