What is Selective breeding and characterization of a black mealworm strain of Tenebrio molitor Linnaeus (Coleoptera: Tenebrionidae) about?

Larvae of Tenebrio molitor Linnaeus are edible insects and are approved as a food ingredient in Korea. They are typically yellow; however, rare black larvae have been found in breeding boxes at insect farms. It is not clear whether black larvae represent a different species that invaded and hybridized with the yellow larvae of T. molitor or whether T. molitor shows intraspecific color variation. In this study, we characterized and identified black larvae for applications in industrial fields as well as accurate breeding and management. First, in a comparative analysis, we did not detect differences in the morphological characteristics of yellow and black larvae and adults, with the exception of larval body color. For accurate species identification, molecular analyses (p-distances and neighbor-joining) were performed based on partial COI sequences of 33 yellow and seven black larvae. Genetic divergence between yellow and black larvae ranged from 0.0% to 2.1%, revealing intraspecific variation. A neighbor-joining analysis strongly supported the classification of the two morphs as a single species. Black larvae were separated from yellow larvae and maintained by selective breeding. A
