Abstract

The calling of female blueberry spanworms occurs primarily during the first few hours of the photophase under controlled laboratory and field conditions. Peak calling occurred 2 h after lights-on at laboratory test temperatures of 20,15, and 10 °C under a light:dark regime of 16:8; duration of calling was prolonged at 10 °C. Under continuous scotophase, female calling activity free-runs at a natural periodicity of ca. 27 h. However, under continuous photophase the circadian rhythm is damped to a low level of activity but maintains a ca.24-h periodicity.

Résumé

L'appel des femelles a lieu principalement durant les premières heures de la photophase en conditions contrôlées de laboratoire et sur le terrain. Les pics d'appel se sont produits 2 h après l'ouverture des lumières aux températures de 20, 15 et 10 °C sous un régime lumière : noirceur de 16 : 8; la durée de l'appel s'est prolongée à 10 °C. En scotophase continue la périodicité de l'appel s'exprime librement à intervalles d'environ 27 h. Cependant, sous photophase continue le rythme circadien est atténué fortement mais maintient une périodicité d'environ 24 h.
