**3.3 The influence of ecological factors on the genetic diversity of** *D. punctatus* **Walker**

Three populations of *D. punctatus* Walker and three populations of geographic subspecies of *D. punctatus* Walker—*D. punctatus spectabilis* Bulter were examined and compared by RAPD. The influence of ecological factors on the genetic diversity is also discussed by the correlation analysis. The correlations between the genetic index and ecological and geographic factors are significant (table40,41).
