Answer: Option A

Solution

Answer: Option A
Solution:
The spotted boll worm is Earias vittella.
Earias vittella, an Asian "spotted bollworm", is a moth species in the family Nolidae. The species was first described by Johan Christian Fabricius in 1794. Most records are from Asia, Australia and certain Pacific islands.
Larvae chew holes into the base of bolls and may hollow out locks. Moist frass usually accumulates around the base of the boll. Larvae may also chew shallow gouges in the boll surface, which can become infected with rot organisms.
