异小杆线虫对亚洲玉米螟越冬代幼虫的侵染力
Infectivity of Heterorhabditis bacteriophora to the overwintering Larva of Ostrinia furnacalis
【摘要】 测定了异小杆线虫(Heterorhabditisbacteriophora)对亚洲玉米螟(Ostriniafurnacalis)的侵染力,结果表明:在供试剂量下,该种昆虫病原线虫对亚洲玉米螟的致死中量LD(50)=17.78±2.74(条线虫/玉米螟幼虫,IJ/L),置信区间为23.15~2.41IJ/L,越冬代玉米螟幼虫对该种线虫高度敏感,应进一步进行田间防治试验。
【Abstract】 Infectivity ted of entomopathogenic nematode to the larva of overwintering O.furnacalis was conducted in laboratory. The results showed that the lethal dose LD50=17.78±2.74(IJ/L). The larvae was sensitive highly to the entomopathogenic nematode, further field trial should be carried out in order to test the efficiency of field application.
