Genetic regulation on the black phenotype mutants of moth and pupa of Helicoverpa armigera (Lepidoptera: Noctuidae).

Genetic regulation on body color of a mutant strain, JBM of Helicoverpa armigera with black body color of pupae and adults, was investigated. Reciprocal crosses between JBM and JBW (a wild strain with yellow brown body color of pupae and adults) were used to determine the inheritance characteristics of body color. Analysis of the ratio of phenotype segregation from the F1 generation, F2 generation, F3 generation, BC1 (F1 x JBM) generation and F1 generation of BC1 indicated that the black body color was controlled by one recessive gene.
