The Consortium's Genotoxicity Technical Working Group is exploring a genotoxicity testing strategy based on the use of <em>in silico</em> modeling and the bacterial reverse mutation and <em>in vitro</em> micronucleus assays and including several options for additional tests to further characterize genotoxicity and mode of action when indicated. The effectiveness of this testing strategy is being evaluated using 13 well-characterized botanicals with existing toxicological data as case studies. A brief overview of each of these 13 botanicals is provided.

The highest concentration of DTO significantly increased <em>Staphylococcus aureus</em> uptake while decreasing phagolysosome formation and bactericidal efficacy. Lastly, exposure to DTO significantly increased basal production of Mcp-1.

New insecticidal molecules, like cyantraniliprole, aim to reduce side effects due to the high toxicity of pesticides and their harmful effects on health and the environment. Its mechanism involves binding to ryanodine receptors, causing rapid calcium ion release. As a new molecule, studies on its effects on mammals are scarce. This work evaluates oral cyantraniliprole's impacts during pregnancy and lactation on maternal behavior and the reproductive system of female offspring. Approved by CEUA-UEL (OF. CIRC. CEUA n. 20/2020), <em>Wistar</em> rats were mated, and after pregnancy diagnosis, divided into control groups, C1, C10, and C150, receiving water and cyantraniliprole at 1, 10, and 150 mg/kg/day, respectively, by gavage. Maternal behavior, offspring physical development, uterine and ovarian histology, and oxidative stress levels were analyzed. Maternal exposure to 150 mg/kg/day was toxic to pregnancy, causing loss of the experimental group. Analysis showed significant changes in maternal behavior in C1 and C10, with increased pup contact, longer breastfeeding, and less cleaning time. No changes in offspring development were observed in C1 and C10.
