Öğe Recent trends in management strategies for two major maize borers: Ostrinia nubilalis and Sesamia nonagrioides(Springer Heidelberg, 2023) Kaçar, Gülay; Butrón, Ana; Kontogiannatos, Dimitrios; Han, Peng; Peñaflor, Maria Fernanda G. V.; Koca, Abdurrahman SamiStem borers (Lepidoptera) are common cereal pests. In many parts of the world, the species Ostrinia nubilalis and Sesamia nonagrioides stand out as important insect pests of economically important crops such as maize. Their management relied mainly on transgenic host plant resistance over the last 25 years. Technologies based on the insecticidal properties of Bacillus thuringiensis-derived proteins allowed widespread pest population suppression, especially for O. nubilalis. However, the recent discovery of Bt resistance, which has revitalized interest in both pests' biology and management, may jeopardize the effectiveness of such transgenic technologies. Historical information on O. nubilalis bionomy may need to be reassessed in light of changing climate conditions and changing agricultural practices, as well as increased production of alternate host crops across its distribution range. The current paper examines the bioecology and historical research that has been conducted to manage these two important maize-boring pests.
