GENETIC HETEROGENEITY AND ADAPTIVE STRATEGIES OF THE LADY BEETLE <i>HARMONIA AXYRIDIS </i>PALL. (COLEOPTERA, COCCINELLIDAE)
Analysis of microstatial variability of the phenetic composition of populations of the lady beetle <i>Harmonia axyridis </i>Pall. is performed in Baikal region of the Primorskii Krai. It is revealed that the phenetic composition of the Baikal <i>H. axyridis </i>population is significantly more labile than in Prumorie. In individual micropopulations the phenoimage is clarified because of the local increase of the frequency of the <i>succinea </i>morp. Individual and family testing of <i>H. axyridis </i>individual from the Primorie and Baikal populations is performed by the quantitative parameters affecting the adaptability - the larval and pupal survival at starvation, critical weight of pupation, the imago weight and fertility. At starvation of larvae of the IV age for 3-4 days, only the <i>succinea </i>morp Individuals from the Primorie population reached the imago stage. The egg-batch value in these imago corresponded to the mean for population (31.2 ± ± 1.06 eggs). The obtained result confirms the earlier expressed suggestion that the <i>succinea </i>morp is distinguished by a high ecologic plasticity. It is able to survive under conditions of the food deficit and is characterized by the intermediate, but stable reproduction
