Knowra Diapause Diapause Diapause is a regulated period of arrested development and reduced activity that helps an animal survive predictable adverse conditions. It is initiated by environmental cues and can persist even when conditions temporarily improve.
Photoperiodism : A biological response to the relative lengths of daylight and darkness. Day length often signals seasonal change early enough to induce diapause.
Dormancy : A period of reduced biological activity that helps an organism endure unfavorable conditions. Diapause is a regulated form of dormancy, especially associated with animal development.
Insect pest management : Strategies for reducing insects that damage crops, stored goods, or human health. Diapause can make pest populations persist through seasons when control measures are applied.
Monarch butterfly : A migratory butterfly native to the Americas, known for its orange-and-black wings. Some monarchs delay reproductive development during migration and overwintering.
Climate change and insects : The effects of changing climate on insect distributions, populations, and life cycles. Shifting seasons can disrupt the environmental cues that time diapause.
Endocrine system : A network of glands and hormones that regulates bodily processes. Hormonal signals coordinate the developmental arrest characteristic of diapause.
Quiescence : A direct, reversible slowdown of activity caused by immediately unfavorable conditions. Unlike quiescence, diapause is programmed in advance and may persist after conditions improve.
Biological control : The use of living organisms to suppress pests or invasive species. Diapause timing affects when natural enemies can be released and remain effective.
Silkworm : The domesticated larva of the silk moth Bombyx mori, raised to produce silk. In many strains, embryos enter diapause in response to maternal and seasonal cues.
Circadian rhythm : An internal biological cycle with a period of roughly 24 hours. Daily timing systems may help organisms measure photoperiod and detect seasonal change.
