title: [Study of temperature-sensitive mutations in the virilis group of Drosophila. 4. Phenogenetics of a temperature-sensitive mutation affecting the development of imaginal discs in Drosophila virilis Sturt].
abstract: The phenogenetics of a new temperature-sensitive mutation diskless-ts (dl-ts, 2nd chromosome) has been studied in D. virilis. The rearing of larvae from the 1st instar at the temperature 31 degrees resulted in the complete or partial arrest of the development of imaginal discs and, consequently, the death of larvae prior to the pupation, at the prepupa stage. The change of temperature from 25 to 31 degrees during the second half of development in the 3rd instar affects the differentiation of imaginal discs. Some organs differentiate completely or partially (eyes, wings, legs) whereas the rest do not develop at all. The sensitive period embraces the whole larval development till the beginning of pupation.
