The relationship between the Huanglongbing pathogen and Diaphorina citri with body color polyphenism: field dynamics, acquisition efficiency, and immunity response

Phenotypic plasticity is generally regarded as a crucial adaptation that enables organisms to survive in the face of environmental changes. Diaphorina citri, a vector of Candidatus Liberibacter asiaticus (CLas) that causes citrus Huanglongbing, displays three distinct body color morphotypes: blue/green, gray/brown, and orange/yellow morphs. Here, dynamics monitoring of D. citri population in the field was established to identify the occurrence peak. The orange/yellow is a shared phenotype, and hence we focused on the two most prevalent color morphs blue/green and gray/brown. We evaluated the life‐history characteristics and susceptibility to insecticides of the two color morphs. For the association between the body color polyphenism and CLas, we compared the CLas acquisition efficiency of field and laboratory populations, and investigated immunological competence of the two color morphs.
