Which virus is NOT used for insect control?

The virus that is not used for insect control is an Arbovirus, which primarily refers to a group of viruses that are transmitted by arthropod vectors, such as mosquitoes and ticks. Arboviruses are often associated with diseases in vertebrates, including humans, and are not typically employed in biological pest control. Their main role is tied to vector-borne diseases rather than the direct control of insect populations.

In contrast, Baculoviruses and Granulosis viruses are specifically utilized in pest management strategies. Baculoviruses are a group of viruses that primarily infect insects, and they are beneficial in controlling pest populations in agriculture by targeting specific insect hosts. Granulosis viruses are a subset of baculoviruses, effective against certain insect larvae, and they contribute to integrated pest management programs by acting as a natural pesticide.

None of these other options, therefore, classify as non-viable for insect control as they are directly applied in pest management, highlighting why the correct answer emphasizes Arboviruses' lack of applicability in that context.
