APES integrated pest management

Define Integrated Pest Management (IPM).

IPM is a sustainable approach to managing pests by combining biological, cultural, physical, and chemical tools in a way that minimizes economic, health, and environmental risks.

True or False: IPM relies solely on chemical pesticides.

False. IPM emphasizes using a variety of pest control methods, including biological and cultural practices, to reduce reliance on chemical pesticides.

List the four core principles of IPM.

- Prevention - Monitoring - Thresholds - Control tactics

What is the role of monitoring in IPM?

Monitoring involves regularly checking pest populations and their impacts to make informed decisions regarding control measures and to determine if thresholds have been exceeded.

Fill in the blank: IPM strategies should aim to minimize __________.

Economic, health, and environmental risks.

Compare 'prevention' and 'control' in IPM.

Prevention involves practices that reduce the likelihood of pest problems, while control refers to the actions taken to manage an existing pest population.

What defines an economic threshold in IPM?

An economic threshold is the pest population level at which control measures should be taken to prevent unacceptable economic damage.

True or False: Cultural controls are part of IPM.

True. Cultural controls alter the environment or practices to reduce pest establishment, reproduction, and survival.

What is the importance of biological control in IPM?

Biological control uses natural enemies, like predators or parasites, to reduce pest populations, offering a more sustainable option than chemical pesticides.

What is meant by 'threshold' in pest management?

A threshold is the pest density level at which action must be taken to prevent unacceptable damage to crops or resources.

List three examples of cultural control strategies.

- Crop rotation - Intercropping - Sanitation practices

Cause → Effect: High pest density.

High pest density leads to increased damage to crops, potentially surpassing the economic threshold and necessitating control measures.

What is the significance of using diverse control tactics in IPM?

Using diverse tactics reduces pest resistance, minimizes environmental impact, and promotes long-term sustainable pest management.

Define 'pest.'

A pest is any organism that negatively impacts human interests, including crops, livestock, and health.

Example: When to apply control measures in IPM?

Control measures should be applied when pest populations exceed economic thresholds established during monitoring.

True or False: IPM is a static, unchanging approach.

False. IPM is dynamic and adapts based on monitoring and changing pest dynamics.

Cultural Control

Practices that modify agricultural systems to reduce pest establishment, reproduction, and survival. Examples: crop rotation, intercropping.

Biological Control

Using natural predators or parasites to control pest populations. Examples: ladybugs for aphids, parasitoids for caterpillars.

Mechanical Control

Physical methods to remove or exclude pests. Examples: traps, barriers, and hand-picking pests.

Chemical Control

Use of pesticides to manage pests. Must consider: target specificity, application timing, and environmental impact.

True or False: Pesticides are always the first choice in IPM.

False. IPM prioritizes non-chemical methods to minimize risks to humans and the environment.

Integrated Control

Combining multiple strategies to control pests effectively and sustainably. Example: using both biological and chemical controls.

Economic Threshold

The pest density at which control measures must be taken to prevent unacceptable economic loss ($/acre).

Fill in the blank: The use of _____ is a key component of cultural control.

crop rotation

Comparison: Chemical vs. Biological Control

Chemical: Fast action, potential resistance; Biological: Slower, sustainable, less resistance.

Pheromone Traps

Used to monitor and trap pests by exploiting their chemical signaling for mating. Helps in timing control measures.

Companion Planting

Planting different crops together to deter pests. Example: marigolds repel nematodes.

Cause → Effect: Poor pest management selection

Increased pest resurgence and resistance, leading to higher economic losses.

What is the goal of IPM?

To minimize environmental impact while controlling pest populations using sustainable practices.

True or False: IPM promotes over-reliance on chemical pesticides.

False. IPM emphasizes a balanced approach that integrates biological, cultural, and mechanical methods, reducing pesticide dependence.

Fill in the blank: IPM uses _____ monitoring to assess pest populations.

regular

Difference between synthetic and organic pesticides?

- Synthetic: man-made, often harmful to ecosystem. - Organic: derived from natural sources, generally less harmful.

Cause → Effect: Excessive pesticide use leads to?

Pest resistance, decreased biodiversity, and potential harm to non-target organisms.

What is biological control in IPM?

Using natural predators or parasites to control pest populations, reducing chemical usage.

List three sustainability considerations in pest management.

- Soil health - Water conservation - Non-target species protection

True or False: IPM is only effective for agricultural pests.

False. IPM can be applied to urban pests, forestry, and other environments.

What role does crop rotation play in IPM?

It disrupts pest life cycles and reduces the buildup of pests in the soil.

Example of a cultural control method?

Changing planting times to avoid peak pest populations.
