Pesticides and Pest Control Questions
Which of the following is NOT a factor to consider when selecting a pest control method?
-
The pest's biology and behavior
-
The environmental impact of the pest control method
-
The cost of the pest control method
-
The availability of the pest control method
D
Correct answer
Explanation
The availability of the pest control method is not typically a major factor to consider when selecting a pest control method, as most pest control methods are readily available.
Which of the following is NOT a common method for controlling pests?
-
Biological control
-
Chemical control
-
Cultural control
-
Mechanical control
D
Correct answer
Explanation
Mechanical control is not a common method for controlling pests, as it is typically labor-intensive and not very effective against most pests.
What is the purpose of using economic thresholds in IPM?
-
To determine when pest control measures are economically justified
-
To estimate the potential yield loss caused by the pest
-
To monitor pest populations over time
-
To identify the most effective pest control methods
A
Correct answer
Explanation
The purpose of using economic thresholds in IPM is to determine when pest control measures are economically justified, taking into account the cost of pest control and the potential yield loss caused by the pest.
Which of the following is NOT a common type of pest monitoring device?
-
Pheromone traps
-
Light traps
-
Sticky traps
-
Soil probes
D
Correct answer
Explanation
Soil probes are not a common type of pest monitoring device, as they are typically used for soil sampling rather than pest monitoring.
What is the concept of integrated pest management (IPM) in sustainable agriculture?
-
Using a combination of methods to control pests
-
Reliance on chemical pesticides
-
Promoting biodiversity in agricultural systems
-
All of the above
A
Correct answer
Explanation
Integrated pest management (IPM) involves using a combination of methods to control pests, including biological control, cultural practices, and chemical pesticides. The goal of IPM is to minimize the reliance on chemical pesticides and promote sustainable pest management practices.
What is the term for the practice of using natural enemies to control pests in agriculture?
-
Biological pest control
-
Chemical pest control
-
Physical pest control
-
Cultural pest control
A
Correct answer
Explanation
Biological pest control involves the use of natural enemies, such as predators and parasites, to control pests in agriculture.
What is the practice of using beneficial insects to control pests in crops called?
-
Biological control
-
Integrated pest management
-
Chemical pest control
-
Cultural pest control
A
Correct answer
Explanation
Biological control involves using beneficial insects, such as ladybugs and lacewings, to control pests in crops, reducing the need for chemical pesticides.
Which of the following is a common type of pest control system used in artwork storage facilities?
-
Chemical pesticides
-
Biological pesticides
-
Physical barriers
-
All of the above
D
Correct answer
Explanation
All of the above are common types of pest control systems used in artwork storage facilities. These systems help to prevent pests from entering and damaging artworks.
Which of the following is a common method of pest control in organic farming?
-
Chemical Pesticides
-
Biological Control
-
Synthetic Fertilizers
-
Genetically Modified Crops
B
Correct answer
Explanation
Biological control involves the use of natural enemies, such as predators and parasites, to control pests in organic farming.
What is the maximum permissible limit of pesticides in fruits and vegetables as per FSSAI regulations?
-
10 parts per million (ppm)
-
20 parts per million (ppm)
-
30 parts per million (ppm)
-
40 parts per million (ppm)
A
Correct answer
Explanation
The maximum permissible limit of pesticides in fruits and vegetables as per FSSAI regulations is 10 parts per million (ppm).
What are some of the strategies used to control invasive species?
-
Biological control
-
Chemical control
-
Mechanical control
-
All of the above
D
Correct answer
Explanation
A variety of strategies are used to control invasive species, including biological control, chemical control, and mechanical control.
Which of the following chemicals is commonly used as a pesticide?
-
DDT
-
Chlorofluorocarbons (CFCs)
-
Polychlorinated biphenyls (PCBs)
-
Dioxins
A
Correct answer
Explanation
DDT is a persistent organic pollutant (POP) that was widely used as a pesticide in the past, but its use is now restricted due to its harmful effects on the environment and human health.
Which of the following is NOT a key component of IPM?
-
Monitoring pest populations
-
Applying pesticides judiciously
-
Releasing beneficial insects
-
Using crop rotation
B
Correct answer
Explanation
Applying pesticides judiciously is not a key component of IPM, as IPM emphasizes non-chemical pest control methods and only uses pesticides as a last resort.
Which of the following is an example of a biological control method used in IPM?
-
Releasing ladybugs to control aphids
-
Applying neem oil to repel pests
-
Using pheromone traps to disrupt mating
-
Removing crop residues to reduce pest habitat
A
Correct answer
Explanation
Releasing ladybugs is an example of biological control, where natural enemies are introduced to manage pest populations.
Which of the following is NOT a cultural control method used in IPM?
-
Planting resistant crop varieties
-
Adjusting planting dates to avoid pest outbreaks
-
Using mulches to suppress weed growth
-
Applying chemical pesticides
D
Correct answer
Explanation
Applying chemical pesticides is not a cultural control method in IPM, as cultural control methods focus on non-chemical pest management practices.
