FAQs on Biocontrol Agents Video Lecture - Capsule course of Botany for NEET

1. What are biocontrol agents?
Ans. Biocontrol agents are living organisms, such as predators, parasites, or pathogens, that are used to control pests and diseases in agriculture and forestry. They act by suppressing the population of the target pest or disease organism, providing an environmentally friendly alternative to chemical pesticides.
2. How do biocontrol agents work?
Ans. Biocontrol agents work through various mechanisms. Predators, such as ladybugs, feed on pests directly, reducing their population. Parasitoids lay eggs inside the pest, which then develop and kill the host. Pathogens, like bacteria or fungi, infect and kill the target pest. These agents can also stimulate the plant's natural defense mechanisms to resist pests or diseases.
3. What are the advantages of using biocontrol agents?
Ans. Using biocontrol agents has several advantages. Firstly, they are environmentally friendly and do not leave harmful residues in agricultural produce. Secondly, they have a targeted approach, affecting only the specific pests or diseases they are intended to control. Moreover, they can be used as part of an integrated pest management strategy, reducing the reliance on chemical pesticides and minimizing the risk of resistance development.
4. How are biocontrol agents introduced into the environment?
Ans. Biocontrol agents can be introduced into the environment in various ways. They can be released directly into the field, either as adults, eggs, or larvae, depending on the life stage of the agent. Alternatively, they can be applied as formulations, such as sprays or granules, containing the agent's propagules. The timing and method of introduction depend on the target pest or disease and the specific biocontrol agent being used.
5. Are biocontrol agents effective in controlling pests and diseases?
Ans. Yes, biocontrol agents can be highly effective in controlling pests and diseases. However, their success depends on several factors, including the specific agent used, the target pest or disease, and the environmental conditions. It is essential to select the most suitable biocontrol agent for the specific situation and to implement proper monitoring and management practices to ensure their effectiveness.
