AbstractTemperature effects on development were studied for two Alberta populations of Ostrinia nubilalis (Hübner), from the South Saskatchewan River valley and the surrounding plains. Lower developmental thresholds for all life stages of both Alberta populations were determined by linear regression. Thresholds for the egg stage were significantly less for plains borers (9.5°C) than for valley borers (10.8°C), and about 2°C lower than for corn borers from the United States. Thresholds in Alberta populations for the 4th (15.3°C) and 5th (14.0°C, plains) instars, and for post-diapause pupation (12.8°C), were much higher than in populations from the United States. Higher temperature thresholds delay development in Alberta populations, thus reducing midsummer pupation. Valley populations developed significantly faster than plains populations during egg development, during the prepupal period of the 5th instar, and during post-diapause pupation. These results explain why valley populations have a partial second generation in some years.

Insecticide Control

The European corn borer, Ostrinia nubilalis Hübner, continues to be a consistent economic pest of field and sweet corn (Zea mays L.) in the upper midwestem United States. In Minnesota alone, O. nubilalis control costs and losses to sweet corn (ca. 50 630 ha) exceed $5,000,000 annually (Noetzel et al. 1985). Despite recent efforts to implement alternatives (Lewis and Bing 1991; Prokrym et al. 1992; Bartels and Hutchison 1993; Bolin et al. 1993), insecticide control continues to play a central role in O. nubilalis management programs.

Abstract European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae), has been present in the United States for over 100 yr and documented on >200 plant species, including economically valuable crops. The reported preferred host of O. nubilalis is corn, Zea mays L. (Cyperales: Poaceae), although it is considered to be a generalist agricultural pest. Life cycles of the two pheromone races, E and Z, align with the seasonality of different agricultural plants. Since the introduction of Bt corn in 1996, overall O. nubilalis presence has declined and suggests that alternative crop plants might not be suitable hosts. We investigated plant vegetation preference of third-instar Z-race O. nubilalis for leaf disks of corn and a variety of other crops using 48 h no-choice and choice tests. Z-race larvae gained more mass on V6 non-Bt field corn leaf disks in comparison to other plant species options. Additionally, a preference for non-Bt field corn leaf disks was observed in most comparisons. Higher consumption of cucumber, Cucumis sativus L. (Cucurbitales: Cucurbitaceae), leaf disks as compared to non-Bt field corn leaf disks suggested an ability to feed on excised leaf tissues of a plant species that does not induce defenses to herbivory.
