Abstract

Ladybirds Harmonia axyridis (Pallas) belonging to the autochthonous and invasive populations from Irkutsk and Sochi that differed in the photoperiodic induction of diapause were crossed in laboratory conditions. The individuals from the Irkutsk population show a strong induction of diapause under short day conditions, while individuals from the Sochi population exhibit very weak photoperiodic induction of diapause. The F1 hybrids obtained from reciprocal crosses demonstrated a photoperiodic reaction similar to that of the parental individuals of the Irkutsk population. The obtained data suggest that the strong photoperiodic induction of diapause is dominant and the effects of male and female genotypes on progeny phenotype are equal.
