Furthermore, low\u2010concentration Cry1Ac exposure led to changes in the messenger RNA (mRNA) levels of genes associated with sex pheromone biosynthesis, as well as alterations in physiological parameters, including cyclic adenosine monophosphate (cAMP) levels, calcium ion (Ca\n                      <jats:sup>2+<\/jats:sup>\n                      ) levels, and the activities of enzymes involved in sex pheromone biosynthesis, ultimately resulting in a significant decrease in sex pheromone production and mating success. Most importantly, exposure to low concentrations of Cry1Ac exhibited transgenerational effects on crucial population metrics such as survival rates and reproductive output.\n
