callosobruchus

piperitone is a natural compound from Piper nigrum L

Callosobruchusic acid is an insect pheromone and monoterpene that has been found as a component of the copulation release pheromone erectin in azuki bean weevils (C. chinensis).1It induces copulation release activity in male azuki bean weevils (EC50= 6.5 ng/insect). 1.Mori, K., Ito, T., Tanaka, K., et al.Synthesis and biological activity of optically active forms of (E)-3, 7-dimethyl-2-octene-1, 8-dioic acid (callosobruchusic acid): A component of the copulation release pheromone (erectin) of the azuki bean weevilTetrahedron39(13)2303-2306(1983)

4-Hydroxyhygric acid is a unique non-protein imino acid (a proline analogue) isolated from the leaves of five species of the tropical leguminous tree Copaifera. It serves as a key chemical defense metabolite for the plant. Studies have demonstrated that it functions as a potent inhibitor of larval development in the seed-feeding bruchid beetle Callosobruchus maculatus and exhibits significant feeding deterrence against the leaf-feeding lepidopteran Spodoptera littoralis. By modulating insect growth and behavior, it acts as a natural biopesticide within the tropical forest ecosystem.
