Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 436-452, May 2026.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Topographical Features of the Lunar Surface Unveiled Through Spherical Geodesic Triangulation Analysis Method of DEM Roughness at Equal Spatial Scales

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract This study introduces an innovative method using equal spherical geodesic triangulation to uniformly sample the digital elevation model (DEM) of the lunar surface, ensuring an even distribution of elevation data. Utilizing spherical spline fitting, we have proposed new methods for calculating slope angles and aspects. An equilateral triangular
