摘要
The whitefly, Bemisia tabaci Gennadius, poses a significant threat to a wide range of crops on a global scale. This research was conducted to study the chemical composition of Cinnamomum zeylanicum bark extracts and its effect on the physiological and molecular aspects of B. tabaci. Gas Chromatography-Mass Spectrometry (GC-MS) revealed 15 significant compounds present in the cinnamon extract, with Cinnamaldehyde (97 %) and alpha-Muurolene (99 %) emerging as the predominant constituents. Bioassays were performed utilizing five concentrations (0.625 %, 1.25 %, 2.5 %, 5 %, and 10 %) of cinnamon extract to evaluate toxicity, indicating that the LC50 value was determined to be 2.34 %. Sublethal concentrations led to a notable decline in adult fecundity, exhibiting a 45 % reduction at a concentration of 2.5 %. Additionally, life table parameters were adversely affected, with a 38 % decrease in the net reproductive rate (Ro) and a 30 % decrease in the intrinsic rate of increase (r). The analysis of gene expression revealed a notable upregulation of genes associated with detoxification, with the relative expression of CYP6CM1 exhibiting a 3.09-fold increase in the F1 generation. The findings indicate that extracts from bark of C. zeylanicum may serve as a promising biopesticide, providing a viable alternative to synthetic insecticides for the management of whitefly populations.
