Bio‐Insecticidal Efficacy of Phytochemicals in Acorus calamus Rhizome and Piper longum Plant Extracts as Green Alternatives to Synthetic Insecticides Against Tribolium castaneum

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 2, June 2026.
ABSTRACT To meet the increasing food demands of a growing global population, agricultural productivity must rise substantially. However, the excessive reliance on synthetic pesticides has resulted in the development of resistance among stored‐product insect pests, necessitating the search for sustainable and eco‐friendly alternatives. The present study

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.

Effect of Storage Duration on Sorghum Seed Quality: Seed Composition and Storage Pest Activity

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
This study aimed to determine the effect of storage duration on sorghum seed quality, specifically focusing on weight loss and storage pest infestation, under laboratory conditions. Eight different sorghum cultivars (Kawali, Numbu, Suri 4, Super 1, Soper 6, Bioguma 1, Bioguma 2 and Bioguma 3) were tested, each with an initial moisture content of 12 ...
