Variation in antennal sensory system in different phenotypes of large fruit-tree tortrix Archips podana scop. (Lepidoptera: Tortricidae)

Quantitative composition of antennal sensilla was studied in different phenotypes of large fruit-tree tortrix imago. Changes in the number of sensilla were observed in individuals reared on lilac: male phenotypes AB and B differed by the number of chaetoid, coeloconic, auriculate, and basiconic sensilla; female offspring of males with AB and B phenotypes differed by the number of short trichoid sensilla and auriculate sensilla of the first type. The relationship between male phenotype and the number of sensilla as well as the impact of parental male genotype on the variation in antennal sensory system in female offspring are discussed.
