摘要： In this study, we successfully established a Bactrocera dorsalis (Diptera: Tephritidae) embryonic cell line, i.e., QAU-Bd-E-2, from the insect eggs. The cells have been stably passaged for more than 60 times in TNM-FH medium with 10% fetal bovine serum (FBS). QAU-Bd-E-2 cells are adherent cells. Most of the cells were round, spindle-shaped, and rod-shaped. Round cells accounted for 82.3%, with a diameter of 13.9 +/- 2.6 mu m; spindle-shaped cells accounted for 9.8%, with the size of 51.2 +/- 11.2 mu m x 10.3 +/- 3.1 mu m; the rod-shaped cells accounted for 7.9%, with the size of 35.2 +/- 9.4 mu m x 12.0 +/- 2.5 mu m. The mitochondrial cytochrome oxidase I subunit (CoI) gene from QAU-Bd-E-2 cells was amplified, and the 657 bp fragment had a 100% similarity with the CoI gene of B. dorsalis, suggesting that the cell line was derived from B. dorsalis. The chromosome number of QAU-Bd-E-2 cells was mostly 12, which is the same as the B. dorsalis chromosome number. The cell density of QAU-Bd-E-2 cells reached the maximum (3.4 x 10(6) cells/mL) at 192 h, and the population doubling time was 31.9 h. Bactrocera dorsalis cripavirus (BdCV) could replicate in QAU-Bd-E-2 cells, suggesting that this cell line could be used for in-depth study of the relationship between virus and host.
