****In North Carolina, for example, potato is more attractive than corn at peak emergence of the first moth flight, and more heavily damaged. *** Other crops sometimes attacked include buckwheat, grain corn, hop, oat, millet, and soybean, and such flowers as aster, cosmos, dahlia, gladiolus, hollyhock, and zinnia. Some of the common weeds infested include barnyardgrass, Echinochoa crus-galli; beggarticks, Bidens spp.; cocklebur, Xanthium spp.; dock, Rumex spp.; jimsonweed, Datura spp.; panic grass, Panicum spp.; pigweed, Amaranthus spp.; smartweed, Polygonum spp.; and others. A good list of host plants is given by Caffrey and Worthley (1927).

Adult female European corn borer, Ostrinia nubilalis (Hübner).
European corn borer has a very wide host range, attacking practically all robust herbaceous plants with a stem large enough for the larvae to enter. However, the eastern strain accounts for most of the wide host range, the western strain feeding primarily on corn. Vegetables other than corn tend to be infested if they are abundant before corn is available, or late in the season when senescent corn becomes unattractive for oviposition; snap and lima beans, pepper, and potato are especially damaged.

I got to this based on Taña's reference above. See the following examples for the seedcorn maggot.

May 2, 2018 - Note that the Deerfield Enviroweather station model for seedcorn maggot is predicting **peak flight emergence** and egg laying for May 4.
