Pendant plusieurs etes au debut juillet entre 1978 et 83, on a observe le comportement de deplacement nocturne des adultes de premiere generation de la pyrale du mais. Dans la journee, les papillons sont immobiles, au repos sur des vegetaux non-hotes. Le vol commence des le crepuscule et le pic se situe vers 20 h 30. Les papillons quittent les bordures et se dirigent rapidement vers le milieu du champ de mais. On note alors une activite sexuelle importante pour l'espece. Le determinisme et les… 
Influence du type de culture et de l'antécédent cultural sur les déplacements des adultes de la pyrale du maïs Ostrinia nubilalis
TLDR
Les captures d'insectes sauvages indiquent à cette époque une prédominance des mâles due probablement à la protandrie d'environ 8 jours chez l'espèce and à une mobilité naturelle supérieure à celle des femelles.
Gene flow in the European corn borer Ostrinia nubilalis: implications for the sustainability of transgenic insecticidal maize
TLDR
To investigate gene flow in the European corn borer, Ostrinia nubilalis (Hübner), the genetic variability at 29 sampled sites from France was studied, and a high stability of allelic distribution was found among samples collected in the same site over two or three different generations, indicating a high Stability of the genetic structure over time.
Modeling the Development of Resistance by Stalk-Boring Lepidoptera (Crambidae) in Areas with Irrigated Transgenic Corn
TLDR
The population dynamics and population genetics of two bivoltine species of corn borers are modeled in a hypothetical region of irrigated transgenic and nontransgenic corn to examine the potential impact of behavior on resistance development.
Modeling the development of resistance by stalk-boring lepidopteran insects (Crambidae) in areas with transgenic corn and frequent insecticide use.
TLDR
The population dynamics and population genetics of two bivoltine species of corn borers are simulated in a hypothetical region of irrigated transgenic and nontransgenic corn where insecticide was applied only to the nontransogenic refuge crop.

Wesimulated thepopulationdynamics andpopulationgenetics of twobivoltine species of corn borers, the European corn borer, Ostrinia nubilalis (Hübner), and the southwestern corn borer, Diatraea
Evaluation of Oviposition Deterrence in Management of Resistance to Transgenic Corn by European Corn Borer (Lepidoptera: Crambidae)
TLDR
The effectiveness of oviposition deterrence on time to resistance to transgenic insecticidal plants was not changed much when the assumptions about behavior in a sensitivity analysis were altered, and the time to 50% R-allele frequency was similar.
