title: [Genetic heterogeneity and adaptive strategies of the lady beetle Harmonia axyridis pall. (coleoptera, coccinellidae)].
abstract: Analysis of microstatial variability of the phenetic composition of populations of the lady beetle Harmonia axyridis Pall. is performed in Baikal region of the Primorskii Krai. It is revealed that the phenetic composition of the Baikal H. axyridis 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 succinea morp. Individual and family testing of H. axyridis 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 succinea 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 succinea 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.
