We recently identified a novel Drosophila circadian output, temperature preference rhythm (TPR), in which the preferred temperature in flies rises during the day and falls during the night. TPR is regulated independently from another circadian output, locomotor activity. Here we describe the design and analysis of TPR in Drosophila.

Insects have an optimal environmental temperature range which they seek to remain within, and many external and internal factors can alter this preference. Here, we describe a cost-effective and simple method to study temperature choice, which allows insects to freely exhibit their natural behaviors.

FAQs
Temperature-sensitive receptors provide information about surrounding thermal conditions. Neural circuits then integrate those signals with internal needs and the organism’s behavioral state, allowing responses to differ according to physiological demands. This integration can guide movement, posture, habitat choice, or activity, linking sensory detection with behavioral thermoregulation rather than treating temperature as an isolated environmental variable.
Internal needs influence how thermal signals are interpreted and acted upon. An organism may adjust movement, posture, habitat choice, or activity as its physiological function or behavioral state changes. Studying these adjustments helps researchers examine how environmental temperature interacts with ongoing behavior, rather than measuring thermal selection as a purely fixed response.
Ectotherms are particularly useful for studying temperature preference because environmental temperature is closely connected to their physiological conditions and behavior. Observing their thermal choices can help investigators examine behavioral thermoregulation and consider how changing thermal environments may affect feeding, reproduction, development, and survival.
Researchers can expose organisms to environmental temperatures and record where they select or remain, along with related movement, posture, habitat choice, or activity. A controlled design makes it possible to examine behavioral responses under defined thermal conditions and relate those responses to physiological function or behavioral state without changing the question being tested.
Measurements of temperature preference can reveal how thermal conditions relate to feeding, reproduction, development, and survival. These outcomes extend the value of observing temperature selection beyond location alone. In behavior research, they help connect an organism’s thermal decisions with broader consequences for performance and persistence under particular environmental conditions.
Temperature preference studies provide behavioral information relevant to predicting responses to climate change. By identifying how organisms select or remain within thermal conditions, researchers can assess how behavior may interact with altered environments. The approach is also useful for designing controlled experiments that examine thermal effects on animal behavior under defined conditions.
