| 1909 I. McCracken in Jrnl. Exper. Zool. VII. 749 The brood..as a whole followed the racial character of its female parent in regard to its voltinism (if I may use this term to express the number of generations destined to be produced in a year). 1923 Genetics VIII. 333 As known for a long time the voltinism is very easily changed by the environment, especially by the incubating temperature. 1980 Canad. Entomologist CXII. 788 Limnoporus notabilis occurs as far south as Arizona.., but we have not seen data concerning the life cycles and voltinism of more southern populations. |
