Molecular and Structural Characterization of Foam Proteins from Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) Nymphs Reveals Adaptive Features and Potential Targets for Pest Control

Archives of Insect Biochemistry and Physiology, Volume 121, Issue 2, February 2026.
Nymphs of Mahanarva spectabilis produce a protective foam that supports survival, reduces plant damage, and contributes to adult population establishment. Proteomic profiling combined with protein sequencing and structural modeling revealed foam proteins enriched in functional domains associated with environmental resilience.

Sewage sludge-based organomineral fertilizer improves phosphorus efficiency in Urochloa brizantha

Revista Brasileira de Ciência do Solo
ABSTRACT Sewage sludge (SS) from wastewater treatment has reasonable phosphorus (P) levels, which could be used as fertilizer in agriculture. However, SS-P content is lower than mineral fertilizers, which limits its operational application.

Agronomic performance of maize and cover crops using composted sewage sludge to supply phosphorus

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract The application of composted sewage sludge (CSS) in crop production offers a sustainable solution for nutrient recycling and reducing reliance on mineral fertilizers. This study evaluated the residual effects of CSS on phosphorus (P) bioavailability and agronomic performance of maize and cover crops in P‐fixing soils of the Brazilian Savannah (
