density. Both strains exhibited a preference for larvae. Rearing strain and life stage were significant factors influencing the probability of cannibalism, and a significant interaction was observed between them. Specifically, the OB-strain showed significantly lower cannibalism than the TU-strain only toward eggs, although it also displayed a lower (non-significant) cannibalism trend across other life stages. These findings provide a basis for optimizing population stability and production efficiency in mass-rearing systems.
