Specific Accumulation of p-Hydroxyphenyllactic Acid as a Metabolite of Tyrosine Metabolism in the Haemolymph of the Larva of Bombyx mori L. : Lepidoptera : Bombycidae : Intoxicated with MTMC (m-tolyl-N-methylcarbamate)

Abstract

Carbamate insecticides caused an elevation in the concentration of hydroxyphenyl compounds in the heamolymph of the silkworm of the silkworm larva at treatment with a lower dose. A specific accumulation of HPLA (p-hydroxyphenyllactic acid) was evident in the silkworm.
