In that framework, <em>Clerodendrum inerme</em> essential oil (EO) was hydrodistiled and analyzed by using gas chromatography-flame ionisation detection (GC-FID) and GC/Mass spectrometry (MS). Isoeugenol (33.1 %) and dibutyl phthalate (29.3 %) were identified as the main oil components. Silver nanoparticles (<em>Ci</em>-based AgNPs) were produced using the methanol (MeOH) extract and characterized microscopically and spectroscopically.

Upon a contact toxicity using treated filter paper, <em>Ci</em>-based AgNPs exhibited the strongest effect, followed by the EO, isoeugenol, dibutyl phthalate, MeOH, and aqueous extracts with larval LC<sub>50</sub> values after 48 h ranged between 14.8 and 53.7 μL/cm<sup>2</sup>, and between 21.3 and 61.1 μL/cm<sup>2</sup> against adults.

At sub-lethal concentrations, the phytochemicals remarkably altered the nutritional parameters and feeding behavior of adult beetles. The phytochemicals significantly inhibited insect's AChE activity.

This study aimed to assess the physical grain quality of common bean genotypes and to select those less prone to changes in these traits as a function of the growing season and cold storage period. Seven black and four carioca common bean genotypes were evaluated over four cold storage periods (0, 60, 120, and 180 days) and two growing seasons (2020 rainy and 2021 dry seasons). Physical grain quality was determined based on moisture, mass of 100 grains, color (L∗, a∗, and b∗values), water absorption, percentage of normal grains, and cooking time. Genetic variability was absent only for moisture content in both commercial classes and for percentage of normal grains in carioca grains. The genotypes exhibited variable responses in physical grain quality traits according to the growing season and storage time. The genotypes least susceptible to quality changes across the two growing seasons are: Fepagro Triunfo, IPR Urutau, and Pérola (mass of 100 grains ≥25 g); LEC 03–16 (very light-colored grains and shortest cooking time); CHP 12 355-02 (highest water absorption and percentage of normal grains); and IPR Urutau (ranked second for shortest cooking time).
