ABSTRACT: In Vietnam, field surveys of N. viridula (Hemiptera: Pentatomidae) on host plants (rice, corn, sesame) was collected 10 color morphs including G, O, F, R, OR, GY, OG, Y, B and C. Among them G and O types were common. The rare phenotype included B, C, Y, OR, OG and GY. Type G is the best adapted to colonize different environments. The emergence of the phenotype depends on the temperature and food (host plants). Type F and R are better adapted to higher temperatures in summer crop on sesame. Low temperatures are the good conditions for the emergence of O type. The 4^th and 5^th instars belong to both in GxG and GxO, had two colors: green and black; among colors, green was the most common. GxO pair created 4 phenotypes: G, O, F, R. The GxG pairs created 3 phenotypes: G, O, F.
