Several cholestenols and cholestadienols were tested for ability to support the growth of the silkworm, Bombyx mori. 5α-Cholest-6-en-3β-ol completely fulfilled the insect sterol requirement, whereas 5α-cholest-8 (9)-en-3β-ol and (20Z)-5, 20 (22)-cholestadien-3β-ol were unable to sustain larval growth at all. The other sterols examined were partially effective as nutrients.
