Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

open access: yesEnvironmental Toxicology, Volume 41, Issue 8, Page 507-522, August 2026.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Soil‐Applied Silicon Does Not Affect the Performance of Aphis craccivora on Cowpea Genotypes

open access: yesEntomological Research, Volume 56, Issue 8, August 2026.
ABSTRACT Cowpea (Vigna unguiculata) is an important crop in tropical regions, where infestations of the black aphid, Aphis craccivora Koch (Hemiptera: Aphididae), can significantly reduce productivity. Silicon (Si) fertilization has been proposed as a strategy to enhance plant resistance to herbivores, although its effectiveness varies among plant ...

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields

open access: yesPest Management Science, Volume 82, Issue 6, Page 5780-5794, June 2026.
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management
