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

open access: yesEntomologia 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.

Complex landscapes, complex diets: DNA metabarcoding reveals lady beetle prey richness increases with landcover diversity

open access: yesEcological Applications, Volume 36, Issue 3, April 2026.
Abstract Understanding the capacity of mobile organisms such as insects to utilize resources across different patches in a landscape can reveal strategies for their conservation. Past research suggests that higher levels of non‐crop habitat or landcover diversity in agricultural regions typically benefit generalist predators who can fortify their diets

Identification of Host Kairomones from Maize, Zea mays, for the Maize Weevil, Sitophilus zeamais

open access: yesJournal of Chemical Ecology, 2012
The maize weevil, Sitophilus zeamais, is an economically important pest of stored grains in tropical and subtropical regions of the world. The behavioral responses of adult S. zeamais to volatile organic compounds (VOCs) from maize seeds, Zea mays, were studied to identify semiochemicals used in host location and provide potential tools for managing ...
