Investigation of Changes in Expression Levels of Detoxification Genes and Mortality in Pieris Brassicae Larvae Exposed to Nepeta Meyeri

The plant extracts have been researched for the last thirty years to improve alternatives to chemical pesticides and to determine their insecticidal effects. It is also known that plant-based biopesticides are generally more specific and innocuous to other organisms. To date, it has been determined that many plant extracts have biocidal properties. However, research on the discovery of new plant extracts with better biocidal properties continues with great excitement. In this study, the biocidal effects of Nepeta meyeri on the larvae of the large cabbage white, Pieris brassicae (Lepidoptera: Pieridae), an important agricultural pest, were investigated. Three several doses (0.75, 1, and 1.25 mg/mL) of N. meyeri extract were given to the third instar larvae using the droplet feeding method. The larvae were taken to the living environment in the climate cabinet (26°C, 65
