摘要
Transferrins are involved in iron metabolism, immunity, xenobiotics tolerance, and development in eukaryotic organisms including insects. However, little is known about the relationship between transferrins and insecticide toxicology and resistance. Three transferrin family genes, NlTsf1, NlTsf2, and NlTsf3, of the brown planthopper, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae)a major insect pest of rice field in Asia, had been identified and characterized in this study. Quantitative polymerase chain reaction results demonstrated that NlTsf1 was significantly higher than the other two genes in different tissues. All of them were expressed at higher levels in abdomen and head than in antenna, leg, stylet, and thorax. Compared with the control, the expression of three N. lugens transferrin family genes decreased dramatically 24 h after treatment with buprofezin, pymetrozine and imidacloprid.
