-
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.
What is the significance of monitoring pest populations in IPM?
-
To determine the need for pest control interventions
-
To assess the effectiveness of pest management strategies
-
To predict future pest outbreaks
-
All of the above
D
Correct answer
Explanation
Monitoring pest populations is crucial in IPM to determine the need for pest control interventions, assess the effectiveness of pest management strategies, and predict future pest outbreaks.
What is the role of economic thresholds in IPM decision-making?
-
To determine the point at which pest control measures are economically justified
-
To assess the severity of pest infestations
-
To predict pest population growth
-
To select the most appropriate pest control method
A
Correct answer
Explanation
Economic thresholds are used in IPM to determine the point at which pest control measures are economically justified, balancing the cost of pest control with the potential economic losses caused by the pest.
Which of the following is NOT a key principle of IPM?
-
Prevention is better than cure
-
Reliance on chemical pesticides
-
Integration of multiple pest management tactics
-
Monitoring pest populations
B
Correct answer
Explanation
IPM emphasizes the integration of multiple pest management tactics, including non-chemical methods, and minimizes reliance on chemical pesticides.
What is the primary goal of using pheromone traps in IPM?
-
To attract and kill pests
-
To disrupt mating and reduce pest populations
-
To monitor pest populations
-
To repel pests from crops
B
Correct answer
Explanation
Pheromone traps are used in IPM to disrupt mating and reduce pest populations by confusing males and preventing them from finding mates.
What is the significance of record-keeping in IPM?
-
To track pest populations and their management
-
To evaluate the effectiveness of pest control strategies
-
To identify trends and patterns in pest infestations
-
All of the above
D
Correct answer
Explanation
Record-keeping in IPM is essential for tracking pest populations and their management, evaluating the effectiveness of pest control strategies, and identifying trends and patterns in pest infestations.
What is the term used to describe the practice of using natural enemies to control pests and diseases in agriculture?
-
Biological control
-
Chemical control
-
Cultural control
-
Physical control
A
Correct answer
Explanation
Biological control is the practice of using natural enemies to control pests and diseases in agriculture. This can be done by introducing beneficial insects, such as ladybugs or lacewings, which feed on pests, or by using microorganisms, such as bacteria or fungi, which can kill pests or diseases.
What is the term for the practice of managing pests and diseases without the use of synthetic pesticides?
-
Integrated pest management
-
Biological control
-
Organic farming
-
Precision agriculture
A
Correct answer
Explanation
Integrated pest management (IPM) is a holistic approach to pest control that emphasizes non-chemical methods, such as biological control, crop rotation, and cultural practices, to manage pests and diseases.
