B.
Larval
C.
Pupal
D.
Embryonic
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
Type of diapause found in Bombyx mori is Embryonic.
In Bombyx mori, embryonic diapause is induced transgenerationally as a maternal effect.
In the silkworm, Bombyx mori, diapause occurs at a specific embryonic stage, i.e. after formation of the germ band with cephalic lobes and telson and sequential mesoderm segmentation.
As long as the eggs are incubated at 25°C, cell divisions and morphological development of the embryos cease.
