Genetical Studies on the Lady-beetle, Harmonia axyridis Pallace Population in Korea

1. Author has surveyed the frequency, geographic variation and micro-geographic variation of the elytral pattern types and the elytral edge of the population of lady-beetle, Harmonia axyridis Pallace which was collected in Seoul and the other 6 localities in Korea. 2. The number of specimen collected were 3.051 in which succinea occupied 88.32 % : Axyridis, 1.00% : spectabilis, 6.145 : and Conspicua , 4.545. 3. Of all 84.80% were found to have elytral edge. 4. There was a little difference in compositional proportation of the above four types to population and in the frequency of elytral edge between the population of west seaside and that of inland of Korea. 5. An interesting micro-geographic variation was observed in Dae-Chun, a beach located on west seaside of south Korea. In this locality , the Succinea occupied 45.23% and 27.805 were found to be provided with elytral edge in the specimen collected in pine trees ( Pinus thunbergii Parlatore), while in the specimen collected in burley field, oak, willow etc. 92.00% were Succinea and 90.93% were found to have elytral edge.
