median lethal dose致死中量
1.In order to provide the evidence for the wide usage of Steinernema feltiae in controlling Heterobostrychus aequalisfor quarantine (purpose), experiments were done indoor to measure the median lethal dose and lethal time of Heterobostrychus aequalis infected by Steinernema feltiae.在室内测定了斯氏线虫对进境原木上的检疫性害虫———双钩异翅长蠹的致死中量和致死中时间,旨在为大规模应用斯氏线虫检疫处理双钩异翅长蠹提供理论依据。
