Effects of Red and Blue Laser Irradiation on the Growth and Development of Ostrinia furnacalis

Year: 2025

Type: article

Abstract: This study evaluated the effects of red and blue laser irradiation on the development and reproduction of the Asian corn borer (Ostrinia furnacalis (Guenée)) under controlled laboratory conditions, aiming to explore its potential for non-chemical pest control. Larvae were exposed to laser light at different wavelengths and intensities, and key biological parameters—including egg hatching, larval duration, pupation, adult emergence, and oviposition—were assessed. Red laser light slightly delayed egg hatching but had minimal effects on subsequent developmental stages. In contrast, blue laser irradiation significantly prolonged the larval period and reduced pupation rates. Combined red–blue treatments produced similar inhibitory effects to blue light alone, suggesting that blue wavelengths were the primary factor driving developmental delays. These findings demonstrate that blue and red–blue laser irradiation can effectively interfere with the life cycle of O. furnacalis, offering a promising approach for sustainable, light-based pest management strategies.
