RELATIONSHIP OF AMBIENT TEMPERATURES TO DIEL PERIODICITIES OF SEX ATTRACTION IN SIX SPECIES OF LEPIDOPTERA1

Published online by Cambridge University Press:  31 May 2012

Abstract

Field studies of male sex attraction rhythms in Argyrotaenia velutinana and five other lepidopterous species reveal that the diel periodicity was modified by ambient temperature. The temperature near the mean hour of attraction appeared to be the most important environmental parameter correlated to the shift in rhythmicity.

Résumé

Des études en plein champ sur le rythme circadien d’attraction sexuelle chez Argyrotaenia velutinana et cinq autres espèces de Lépidoptères montrent que l’heure d’expression du rythme est modifiée par les températures ambiantes. La température aux environs de l’heure d’attraction semble être le paramètre météorologique le plus important en corrélation avec ce rajustement du rythme.
