Voltinism

Voltinism is a term used in biology to indicate the number of broods or generations that an organism has each year. The term is most often applied to insects, and is particularly in use in sericulture, in which silkworm varieties vary in their voltinism.

The following adjectives describe organisms:

  • Univoltine (monovoltine) – having one brood or generation per year
  • Bivoltine (divoltine) – having two broods or generations per year
  • Trivoltine – having three broods or generations per year
  • Multivoltine (polyvoltine) – having more than two broods or generations per year
  • Semivoltine – with two meanings:
  • being less than univoltine; having a brood or generation less often than once per year
  • having a generation time that lasts more than one year.
