Properties of the circadian and annual timing systems are expected to vary systematically
with latitude on the basis of different annual light and temperature patterns at higher …

Numerous studies indicate that target gene silencing by RNA interference (RNAi) could lead
to insect death. This phenomenon has been considered as a potential strategy for insect …

Our highly seasonal world restricts insect activity to brief portions of the year. This feature
necessitates a sophisticated interpretation of seasonal changes and enactment of …

Most organisms possess time-keeping devices called circadian clocks. At the molecular
level, circadian clocks consist of transcription–translation feedback loops (TTFLs). Although …

The short day lengths of late summer are used to program the overwintering adult diapause
(dormancy) of the Northern house mosquito, Culex pipiens. Here, we investigated the role of …

The fruit fly Drosophila melanogaster is an established model organism in chronobiology,
because genetic manipulation and breeding in the laboratory are easy. The circadian clock …

In this article, we explore links between circadian clocks and the clock involved in
photoperiodic regulation of diapause in insects. Classical resonance (Nanda–Hamner) and …

Photoperiodism is an adaptive response used by organisms to assess day length and
anticipate upcoming seasons and to coordinate their (or their offspring's) development and …

This review examines the spectral sensitivities of photoperiodic responses in insects and
mites in relation to circadian‐based models for the photoperiodic clock. It concludes that …

The development of reverse-genetic tools in “nonmodel” insect species with distinct biology
is critical to establish them as viable model systems. The eastern North American monarch …
