If you mean by Brahmaloka the world of the god Brahma (part of the Trinity), then yes, all the worlds below belong to the realm of dissolution through Pralaya and Mahapralaya.
Prakrutha lokas is a word I have not read. The Vedas and the Upanishads speak of Maya, worlds under the Influence of Maya. In the original literature, there are the Vidyamayi and Avidyamayi Maya, which have been largely forgotten in the later Vedanta. Sri Krishna speaks of Paraprakriti, which is not of the nature of ignorance but of the Divine Himself. The worlds created by the Divine Supernature, Paraprakriti, are worlds of Truth, infinity, eternity, not subject to Time and dissolution. The Supramental belongs to these four higher worlds.
Affectionately,
