It's around the same time too, 1942! I wonder if both pests are culprits?
Trying to find anything more about the moth, it's a valid name at least for the species epithet.
Emboloecia sauzalitae papaipemoides

You can download or just open the pdf of an old book where the moth is described on pages 95 & 96, it lists California but doesn't give any other info.
