Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

Entomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 527-535, June 2026.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.

Insecticidal Activity of Trichilia hirta L. (Sapindales: Meliaceae) Extracts Against Spodoptera frugiperda (Lepidoptera: Noctuidae) Larvae and the Identification of Bioactive Compounds

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Fruits of Trichilia hirta were extracted and fractionated according to solvent polarity. The resulting partitions were screened for insecticidal activity by evaluating larval mortality and weight after 7 and 14 days. LC‐MS analysis of the most active fraction enabled the annotation of secondary metabolites potentially associated with the observed ...

Controlling Scaphoideus titanus: are pyrethrins and phytoseids compatible?

OENO One
Mites of the family Phytoseiidae are important generalist predators in European vineyards, where they regulate phytophagous tetranychid and eriophyoid mites. As long as they are not affected by pesticides, they survive, even without prey.
