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...
