Intercrop effects on the distribution of populations of the European corn borer, Ostrinia nubilalis, in maize

Field investigations conducted from 1982 to 1984 to assess intercrop effects on the distribution of Ostrinia nubilalis (Hübner), Lepidoptera, Pyralidae, in maize revealed that the incidence of damage by O. nubilalis was influenced significantly by the proximity of maize to potato. Maize fields adjacent to potato fields had a lower incidence of early season damage by O. nubilalis and a higher incidence of late-season damage than maize isolated from potato.
