Stage specific vulnerability of the laboratory populations of Lipaphis erysimi (kaltenbach) to some convential insecticides

摘要：

Insect susceptibility is inversely proportional to the physiological state of the tested individuals. The present study investigates the instar differences in insecticide receptiveness of Lipaphis ersimi (Kaltenbach) populations. The results indicate an increased vulnerability of latter instars as comparison to earlier ones. These results show the disagreement to past studies. The reasons for this vagueness are also explained.
