31

Argyrotaenia is a of tortricid moths in the tribe Archipini, established by Stephens in 1852. The genus includes commonly known as leafroller moths due to the larval habit of rolling or folding leaves for shelter. Several species are economically significant agricultural pests, particularly in orchards. The genus has a primarily New World distribution, with species ranging from North America through Central and South America, and has been recorded as far south as Argentina and Chile. Some species exhibit in wing pattern and size.

Identification

in this are small to medium-sized tortricids with characteristic wing patterns that often include bands or mottled coloration. -level identification typically requires examination of genitalia. may show in wing shape and pattern, as documented in A. socoromaensis where males and females differ in wing size and markings. The genus is distinguished from related tortricid genera by genitalic characters, particularly in the male valva and female sterigma.

Habitat

vary by and include temperate and tropical forests, agricultural areas, and arid Andean environments. A. socoromaensis was described from the arid Andes of northern Chile at elevations in the Andean zone. A. amatana is precinctive to Florida. Many species occupy deciduous forest habitats where their plants occur.

Distribution

New World distribution: North America (eastern Great Plains to Atlantic coast, north to Canada), Central America, and South America. Argentina records include Neuquén, Buenos Aires, and Tucumán provinces. A. socoromaensis represents the first Chilean record for the . A. sphaleropa is widespread in the New World tropics. GBIF records indicate presence in Denmark, Norway, Sweden, Vermont (USA), and other US locations, though these may represent introduced or data artifacts.

Seasonality

periods vary by and latitude. A. velutinana is active over much of the year. A. amatana flight period is documented for Florida. Spring-emerging species occur in temperate regions, with some species showing single- cycles and others multivoltine.

Host Associations

  • Stevia philippiana - larval Asteraceae; for A. socoromaensis
  • Lupinus oreophilus - larval Fabaceae; for A. socoromaensis
  • deciduous trees and shrubs - larval general range for many Argyrotaenia including apple, oak, elm
  • herbaceous plants - larval broad range including leaves and fruits
  • citrus - larval referenced in literature for related , though A. citrana report from South America was erroneous

Life Cycle

Complete with , larva, pupa, and stages. Larvae are leafrollers, constructing shelters by folding or rolling leaves. occurs in a folded leaf on the ground in A. velutinana. Some have one per year; others are multivoltine.

Behavior

Larvae exhibit leaf-rolling , creating shelters by folding or rolling leaves and feeding within. Male A. velutinana show reduced ability to locate calling females in the presence of synthetic , demonstrating potential for . are and attracted to light.

Ecological Role

Larvae function as herbivores on diverse plant . Some are occasional to significant agricultural pests in orchards, particularly on apple. The represents a component of tortricid diversity in New World , with A. socoromaensis representing the first documented member of tribe Archipini in Chile.

Human Relevance

Several are agricultural pests of economic concern, particularly in apple orchards. A. velutinana (redbanded leafroller) is an occasional orchard pest east of the Rocky Mountains. -based has been investigated as a management strategy. Taxonomic research on the supports identification and management of pest species.
