Effects of a Compound Derived from Abietic Acid on Silk Production of the Solkworm, Bombyx mori L. : Lepidoptera : Bombycidae

Abstract

When the 5th-instar larva of the silkworm, Bombyx mori L., was fed with methyl 6, 7-dioxo-5α, 10α-podocarpa-8, 11, 13-trien-15-oate (compound A-11), the instar period was prolonged and silk productivity increased. The relationship between the method of administration and the specific quality of cocoon were examined.
