Baculoviruses are pathogens that attack:

The correct answer is Option (1) → Insects

Baculoviruses are used in biological control of insect pests. Most of those used belong to the genus Nucleopolyhedrovirus. They are species-specific, so they kill the target pest and leave other organisms unharmed.

Option (1) Insects — Correct. Baculoviruses are pathogens that attack insects and other arthropods. They are species-specific, so they are used in biocontrol without harming useful insects.
