Mansoa alliacea (Lam.) A.H. Gentry (Bignoniaceae) leaf extracts was tested for its toxicity on the larvae of Bombyx mori L. Phytochemical analysis of different extract of leaves of Mansoa alliacea (Bignoniaceae) was prepared with the five different solvents, which revealed the presence of various bioactive compounds. Quantitative analysis showed highest amount of phenol (49.95 ± 0.087 mg g−1) and flavonoids content (9.27 ± 0.065 mg g−1) in the solvent methanol. Total tannin content was also found highest in methanol (11.19 ± 0.065 mg g−1). No mortality was observed in the toxicity tests when the six day old silk larvae were fed with mulberry leaves treated with four concentrations viz., 0.25%, 0.50%, 0.75% and 1% of Mansoa alliacea (Bignoniaceae) leaf extract for three days. The results revealed that the leaf extract had no harmful effect on the survival of larvae on consumption of the treated mulberry leaves. Normal feeding and growth pattern was observed in all the larvae, which indicated that the leaf extract of Mansoa alliacea (Bignoniaceae) was non-toxic in nature.
