| 摘 要： | 为明确球孢白僵菌-玉米共生体对亚洲玉米螟幼虫取食行为及取食选择性的影响，本文通过室内控制试验，采用培养皿叶盘法，研究了共生体对亚洲玉米螟初孵幼虫和3龄幼虫的选择、非选择性取食的影响。结果表明，在48 h非选择性试验中，亚洲玉米螟初孵幼虫在球孢白僵菌-玉米共生体叶片组织（处理组）上的取食率显著低于未接种球孢白僵菌玉米叶片（对照组），第48 h时在共生体和对照玉米上的幼虫取食率分别为35.7%和62.5%，差异极显著；3龄幼虫在共生体茎秆组织上的取食率与对照组玉米差异不显著。在48 h选择性试验中，初孵幼虫在共生体玉米叶片组织上的取食率显著低于对照组，共生体玉米叶片组织上的幼虫取食率随时间的增加呈下降趋势，第48 h时在共生体和对照玉米上的幼虫取食率分别为6.3%和20.6%，差异极显著；3龄幼虫在共生体和对照组玉米茎秆组织上的幼虫取食率随时间的增加呈上升趋势，其中对照组幼虫取食率显著高于处理组，第48 h时在处理组和对照组玉米上的幼虫取食率分别为33.1%和45.6%，差异极显著。本研究初步表明，球孢白僵菌-玉米共生体对亚洲玉米螟幼虫的取食行为有显著的抑制和忌避作用。

| Abstract: | The effects of Beauveria bassiana-maize symbionts on feeding behaviors and feeding preference of the Asian corn borer (ACB) were investigated with a dish leaf-disc method in the laboratory using neonate and 3rd instar larvae of ACB. Our results showed that, in a 48-hour no-choice experiment, feeding on leaves with B. bassiana-maize symbionts (the treatment) by ACB neonates was significantly less than that on leaves without B. bassiana (the control), and the percentages of larvae feeding on the treatment and the control were significantly different, being 35.7% and 62.5%, respectively. However, the percentages of 3rd instars feeding on the stem showed no difference between the treatment and the control. In a 48-hour choice experiment, feeding on leaves by ACB neonates was significantly less in the treatment than in the control, the percentages of neonates feeding on the treatment leaves decreased with extension of time, which were significantly different at the time point of 48 hour between the treatment and the control (6.3% and 20.6%, respectively). The percentages of 3rd instars feeding on the stem of both the treatment and the control increased with extension of time, being significantly higher in the control than in the treatment. At the time point of 48 hour, the percentages in the treatment and the control were 33.1% and 45.6%, respectively. Our results indicate that, there is an obvious inhibition and avoidance effect of B. bassiana-maize symbionts on the feeding ACB. |
