This study was carried out to determine the toxicity of Pisum sativum L., extract (Pea Extract) for the subterranean termite, Coptotermes gestroi (Isoptera: Rhinotermitidae). Yellow field peas (Pisum sativum L.) are particularly rich in protein. A solid-liquid hydroalcoholic extraction process was employed on the dried form of pea seeds to obtain one particular peptide PA1b (Pea Albumin 1, subunit b) without any known toxicity or allergenicity. This peptide was extracted from two different routes: with and without delipidation. The two versions had been tested and compared for its efficacy during rapid laboratory screening tests on cellulose paper towards C. gestroi. Cellulose consumption, termite behavior and termite mortality were recorded. This work suggested the good potential of Pea Extract as biobased bait toxicant for the control of subterranean termite populations Coptotermes gestroi in Reunion Island.
