The effect of rearing time in the laboratory (estimated as the number of consecutive generations) on survival, size and fecundity of two colonies of Harmonia axyridis was evaluated. It was found that colonies of this insect can be sustained in mass rearing for at least 4.25 years (17 generations) without significantly affecting its expression of vigour, reproductive performance and field behaviour (as a biological control agent of plant pests).
