Dr. McGaughey has found that the Indian mealmoth can develop resistance in only two or three generations, and other researchers report that the tobacco budworm can produce it in about a dozen generations.

This species is often confused with the related Indianmeal Moth (Plodia interpunctella).

Another species whose larvae share that name is the Indian meal moth (Plodia interpunctella), though this species is not available commercially.

The Indian Meal Moth (Plodia interpunctella), alternatively spelled Indianmeal Moth, is a pyraloid moth of the family Pyralidae.

Another common name, less unambiguous, is "flour moth", which (like "pantry moth", occasionally used for the present species) may also refer to the related Indianmeal Moth (Plodia interpunctella).

There are also some species of moths, most commonly the snout moths, Scirpophaga incertulas, Chilo polychrysus, Cnaphalocrocis medinalis, Achyra nudalis, Scirpophaga nivella, Leucinodes orbonalis, Corcyra cephalonica, Plodia interpunctella and soforth.
