17 Questions
What is a key advantage of biological control in crop protection?
Conservation of beneficial organisms
Which Baculovirus classification is associated with controlling Hymenoptera?
Gamma-: NPV, Hymenoptera
What is one reason consumers are taking an increasingly critical look at the use of microorganisms in crop protection?
Concerns about environmental impact and safety
Which trait by genetic modification is mentioned as possibly improving root colonizing ability and resistance to environmental factors?
Enhancing root colonizing ability
What does the registration of microbials, like metabolites and exotic strains, remain critical for in crop protection?
Maintaining efficacy and regulatory standards
What is the definition of 'biocontrol' according to the text?
The use of living organisms to suppress the population density or impact of a specific pest organism, making it less abundant or less damaging than it would otherwise be.
Which of the following is considered an 'active substance' under this regulation?
Micro-organisms having general or specific action against harmful organisms or on plants.
What is an example of a 'beneficials, microorganisms/virus' in the context of biocontrol?
Bacillus thuringiensis, a bacterium that is toxic to certain insects.
Which of the following is an example of a biocontrol agent's mode of action?
Oral uptake of a Bacillus thuringiensis toxin by insects.
What is an example of the 'microbiology/biotechnology' aspect of biocontrol agents?
The propagation of Cydia pomonella granulovirus (CpGV) in C.pomonella larvae.
Which of the following factors is not mentioned in the text as influencing the development and use of biocontrol agents?
The specific application technology used to apply the biocontrol agent.
What is the difference between classical biological control and inoculation biological control?
Classical biological control involves the introduction of a new beneficial species, while inoculation biological control involves the release of living organisms to control pests temporarily.
What is the primary goal of conservation biological control?
To modify the environment to enhance natural enemies and reduce pest effects.
What distinguishes inoculation biological control from inundation biological control?
Inoculation biological control aims for permanent pest control, while inundation biological control is only temporary.
Which method exclusively relies on living organisms to control pests?
Inundation biological control
What is the main purpose of classical biological control?
To permanently establish exotic beneficial species for pest control.
How does conservation biological control differ from inoculation biological control in terms of sustainability?
Conservation biological control enhances natural enemies for extended periods without permanent establishment, while inoculation biological control expects temporary multiplication for long-term pest management.
Test your knowledge on different methods of biological control including classical biological control, conservation biological control, and the use of beneficials, microorganisms, viruses, and semiochemicals. Explore how these methods help protect and enhance natural enemies to reduce the impact of pests.
