Study of individual and sex genetic diversity among each genus and between two genera of Chrysopa and Chrysoperla (Neuroptera, Chrysopidae) based on RAPD-PCR polymorphism.

RAPD (random amplification of polymorphic DNA) was used to distinguish the genetic diversities between two genera of Chrysopa and Chrysoperla (Neuroptera, Chrysopidae). Sixty specimens were collected in different places in Kermanshah, west of Iran. The wing venation was used for identification of each type of two genera, and the gender was determined by study of external genitalia. 20 random primers were used for polymerase chain reaction. Then, the electrophoresis was used for separation of the PCR products on agarose gel. 294 bands were amplified, which 235 bands were polymorph and others (59s) determined as monomorph. The electrophoresis results showed that the primers OPA02 with 19 bands and OPA03 with 8 bands successively amplified the maximum and minimum of bands among the applied primers. The results showed that there are maximum of genetic diversity and minimum of genetic similarity between Chrysopa male (Chrysopa-M) and Chrysoperla female)Chrysoperla-F) population, in contrast, there are maximum of genetic similarity and minimum of genetic diversity between Chrysoperla-M and Chrysoperla-F, and Chrysopa-M and Chrysopa-F. There are also more genetic similarities, between males and females of Chrysopa and Chrysoperla, than between male of Chrysopa with female of Chrysoperla or vice versa.
