The multicolored Asian ladybird beetle, Harmonia axyridis, which demonstrates typical genetic polymorphism in its elytra color patterns. Early studies have color polymorphism in terms of geographical clines while a few investigated temporal populations in Coccinellidae. Nevertheless, note that geographical and temporal morph variation does not always correspond to what is expected from thermal and industrial adaption theories. A recent study of transformation and RNAi of the ladybird beetle, however, there is yet no evidence to indicate the variation is genetic or environmental factors. Here we describe a relatively new molecular fingerprinting technique, amplified fragment length polymorphism (AFLP). Because we think that color polymorphism in Coccinellidae is affected by genetic polymorphism. In total 38 markers were scored from which some markers were polymorphic. Supsequent UPGMA cluster analysis revealed 3 major group of Harmonia axyridis populations. But for strains that are more genetically similar, different primer combinations may be need to generate enough polymorphic marker.
