Pesticides and Pest Control Questions
Which of the following is an example of a cultural control method in IPM?
-
Releasing ladybugs to control aphids
-
Applying chemical pesticides
-
Using crop rotation to disrupt pest life cycles
-
Removing infested plant material
C
Correct answer
Explanation
Crop rotation is a cultural control method that involves rotating different crops in a field over time to disrupt pest life cycles and reduce pest populations.
Which of the following is NOT a benefit of using cultural control methods in IPM?
-
Reduced reliance on chemical pesticides
-
Increased biodiversity in the ecosystem
-
Potential for pest resurgence
-
Lower production costs
C
Correct answer
Explanation
Cultural control methods generally do not lead to pest resurgence, as they focus on long-term prevention and management rather than rapid pest suppression.
Biological control agents are often selected based on their:
-
Ability to prey on or parasitize a wide range of pests
-
Specificity to the target pest species
-
Compatibility with the local ecosystem
-
All of the above
D
Correct answer
Explanation
Biological control agents are selected based on their ability to prey on or parasitize the target pest species, their specificity to avoid harming beneficial organisms, and their compatibility with the local ecosystem.
Which of the following is an example of a chemical control method in IPM?
-
Releasing ladybugs to control aphids
-
Applying chemical pesticides
-
Using crop rotation to disrupt pest life cycles
-
Removing infested plant material
B
Correct answer
Explanation
Chemical control involves the application of chemical pesticides to kill or repel pests.
Which of the following is NOT a prohibited substance in organic aquaculture?
-
Synthetic pesticides
-
Antibiotics
-
Organic fertilizers
-
Genetically modified organisms (GMOs)
C
Correct answer
Explanation
Organic fertilizers are not prohibited in organic aquaculture, as they are derived from natural sources and do not contain synthetic chemicals.

What is the Rotterdam Convention's vision?
-
A world where hazardous chemicals and pesticides are used safely and sustainably.
-
A world where human health and the environment are protected from the harmful effects of hazardous chemicals and pesticides.
-
A world where the risks associated with hazardous chemicals and pesticides are minimized.
-
A world where the benefits of hazardous chemicals and pesticides outweigh the risks.
-
All of the above.
E
Correct answer
Explanation
The Rotterdam Convention's vision is 'A world where hazardous chemicals and pesticides are used safely and sustainably, human health and the environment are protected from the harmful effects of hazardous chemicals and pesticides, the risks associated with hazardous chemicals and pesticides are minimized, and the benefits of hazardous chemicals and pesticides outweigh the risks'.
Which of the following is NOT a common method of forest disease management?
-
Chemical control
-
Biological control
-
Cultural control
-
Mechanical control
A
Correct answer
Explanation
Chemical control is not a common method of forest disease management, as it can have negative impacts on the environment and human health.
What are some of the mathematical methods used in Mathematical Toxicology?
-
Differential equations
-
Partial differential equations
-
Integral equations
-
Numerical methods
-
All of the above
E
Correct answer
Explanation
Mathematical Toxicology uses a variety of mathematical methods, including differential equations, partial differential equations, integral equations, and numerical methods, to model the complex processes involved in toxicity.
Which of the following is a common method of pest control in Indian agricultural engineering?
-
Chemical pesticides
-
Biological control
-
Cultural practices
-
All of the above
D
Correct answer
Explanation
Chemical pesticides, biological control, and cultural practices are all common methods of pest control used in Indian agricultural engineering.
Which of the following is an example of a toxic chemical that can disrupt ecosystems?
-
DDT
-
PCBs
-
Dioxins
-
All of the above
D
Correct answer
Explanation
DDT, PCBs, and dioxins are all known to disrupt ecosystems.
Which of the following is NOT a key component of IPM in natural areas?
-
Prevention
-
Monitoring
-
Targeted control
-
Routine pesticide application
D
Correct answer
Explanation
Routine pesticide application is not a component of IPM in natural areas, as it can harm beneficial insects and disrupt the ecosystem balance.
What is the first step in implementing IPM in a natural area?
-
Identifying pest thresholds
-
Applying pesticides
-
Monitoring pest populations
-
Releasing beneficial insects
A
Correct answer
Explanation
Identifying pest thresholds is the initial step in IPM, as it helps determine the level of pest infestation at which control measures should be implemented.
Which of the following is an example of a non-chemical pest control method used in IPM?
-
Biological control
-
Chemical control
-
Cultural control
-
Mechanical control
A
Correct answer
Explanation
Biological control involves introducing natural enemies of pests, such as predators or parasites, to control pest populations.
