Laboratory evaluation of PA1b, an insecticidal protein extracted from pea seeds (Pisum sativum), as bait active ingredient against the subterranean termite Coptotermes gestroi (Blattodea: Rhinotermitidae) in tropical zones
2024 - IRG/WP 24-11038
Coptotermes gestroi (Wassman 1896) is one of the worst pests in tropic areas, economically. Two types of curative methods are used since decades to eliminate colonies that attack constructions: injection of biocidal treatment solutions on wood, walls and soil, and population control using baits. In application of the current regulations, the first technique can no longer be used in Europe, to lim...

Efficacy performance of Pea Extract as bait toxicant for termite control in Reunion Island
2024 - IRG/WP 24-11050
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...

Field facility for conducting wood durability tests at LSU Agricultural Center
2024 - IRG/WP 24-41012
Efforts by Louisiana State University Agricultural Center (LSU AgCenter) to conduct wood durability research on C. formosanus and other wood-related topics, have led to establishing three field research sites to test wood products against Formosan subterranean termites (New Orleans, La), and native subterranean termites (Franklinton, LA), and to test utility poles for outdoor exposure, decay resis...
