Residual efficacy of spinosad-treated surfaces on Rhyzopertha dominica and Tribolium castaneum adults

Julius-Kühn-Archiv, 2018
Rhyzopertha dominica and Tribolium castaneum cause massive losses in stored food. These insects are effectively controlled by synthetic insecticides and fumigants but they accompany many demerits on biotic and abiotic environment. Spinosad is a bacterial

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 ...

Development of Nanocomposite Bioactive Diffusion Films (BDFs) Combined With Gamma Irradiation for Control of the Rice Weevil Sitophilus oryzae, a Stored Product Pest

Journal of Food Science, Volume 91, Issue 1, January 2026.
ABSTRACT The fumigant toxicity of 6 essential oils (EOs) (Mediterranean, Southern, citrus, cinnamon, Asian, and savory thyme), 2 citrus extracts (CEs: organic OCE and natural NCE), and 2 active formulations (microfluidized nanoemulsions AF‐1 and AF‐2) was investigated for control of rice weevil (Sitophilus oryzae), a stored product pest.

Epoxy tetrahydrophthalimides as potential bioactive agents: synthesis and computational study

Pest Management Science, Volume 81, Issue 12, Page 7995-8006, December 2025.
Epoxy tetrahydrophthalimides were synthesized and evaluated for phytotoxic activity. Some compounds showed greater inhibition than S‐metolachlor against Sorghum bicolor. Docking studies indicated interaction with mitogen‐activated protein kinase, suggesting it as a potential target.
