| 摘 要： | 采用不同浓度的球孢白僵菌Bb050230 菌株，对棕榈蓟马成虫和若虫进行致病力测定。结果
表明：球孢白僵菌对棕榈蓟马的成虫和若虫具有较高的毒力，用浓度为3.0×108 个·mL-1 的球孢白僵菌
孢子悬浮液接种8 d 后对棕榈蓟马成虫和若虫的累计校正死亡率分别为85.76% 和83.25%，致死中时间
（LT50）最短分别为4.43 d 和4.79 d，第8 天棕榈蓟马成虫和若虫的致死中浓度（LC50）分别为3.106×105
个·mL-1 和3.284×105 个·mL-1。

| Abstract: | Virulence of Beauveria bassiana Bb050230 strain at different concentration to the
adults and larvae of Thrips palmi Karny was evaluated in the laboratory. The results indicated that the
strain Bb050230 had higher pathogenicity to adults and larvae of Thrips palmi Karny．After inoculating
strain Beauveria bassiana Bb050230 with 3.0×108 conidia·mL-1 for 8 days，the correct mortality
of adult and larvae were 85.76% and 83.25%，respectively. The median lethal times（ LT50） were 4.43
days and 4.79 days. The median lethal concentration（LC50） for adult and larvae at the 8th day were
determined as 3.106×105 conidia·mL-1 and 3.284×105 conidia·mL-1，respectively. |
