Abstract

1. We have observed the frequency , geographi variation and microgeographic variation of the elytral pattern types and the elytral edge of the population of Lady-beetle, Harmonia axyridis PALLACE, collected in Jinju and other 6 localitites in South Korea. 2. the number of specimen collected were 6,625 in which Succinea was 90.32% : Axyridis ; 0.74% : Spectabilis , 3.82% ; and Conspicua 5.07%. 3. We have found that 92.26% of all specimens have elytral edge. 4. There were some differences in the compositional of the elytral pattern types and elytral edge to the population among the Western seaside , inland and southern seaside of South Korea , whereas as great difference was in the compositional proportion tot he population of Spectabilis between the western and southern seaside . There was also a gret difference of the elytral edge between the inland and southern seaside. 5. A micro-geographic variation was observed in Jinju , located on southern area of South Korea. In the samples collected from the pine trees at Jinju area the Succinea occupied 73.25%, and 69.61 % were found to be provided with elytral edge, while in the general population 92.46% of specimen were Succinea and 98.35% were found to have elytral edge.
