Baculoviruses are pathogens that attack insects and other arthropods. The majority of them used as a biological control agents are in the genus Nucleopolyhedrovirus.These viruses are excellent candidates for species-specific, narrow spectrum insecticidal applications. Infection with baculoviruses occurs when susceptible hosts eat virus particle present on foliage and dies. These are important in organic farming because of their specific action on harmful insects without causing any damage to beneficial insects as well as to the environment.

Which of the following statements regarding baculoviruses as biocontro...
Statement a: The majority of baculoviruses used as biocontrol agents are included in the genus - Nucleopolyhedrovirus.
Explanation: This statement is correct. Baculoviruses are a family of viruses that infect insects. The majority of baculoviruses used as biocontrol agents belong to the genus Nucleopolyhedrovirus (NPV). NPVs are highly specific to certain insect species and are widely used in biocontrol programs to target specific pests.
Statement b: Infection with baculoviruses occurs when susceptible hosts (e.g., some specific insects) eat virus particles present on foliage and die.
Explanation: This statement is correct. Baculoviruses have a unique mode of transmission. Infection occurs when susceptible hosts, such as specific insects, consume virus particles that are present on foliage or other food sources. Once ingested, the virus particles replicate within the insect's body, leading to the death of the host.
Statement c: Baculoviruses are important in organic farming because of their specific action on harmful insects without causing any damage to beneficial insects as well as to the environment.
Explanation: This statement is correct. Baculoviruses are highly specific to certain insect species and do not have a broad spectrum of activity. This specificity makes them ideal for use in organic farming, where the goal is to control harmful insect pests while minimizing harm to beneficial insects and the environment. Baculoviruses have been successfully used in organic agriculture to control pests like the corn earworm, cabbage looper, and gypsy moth.
Therefore, all of the given statements (a, b, and c) are correct. Baculoviruses, specifically those belonging to the genus Nucleopolyhedrovirus, are widely used as biocontrol agents. Infection occurs when susceptible hosts consume virus particles, and these viruses are important in organic farming due to their specific action on harmful insects without causing damage to beneficial insects or the environment.
