Our study presents a community-based monitoring system that focuses on three invasive potato tuber moth species (PTM). The monitoring was developed and implemented by young farmers in a remote mountainous area of Ecuador. Local participants collected data from the PTM invasion front, which revealed clear connection between the abundance of one of the species (Tecia solanivora) and the remoteness to the main market place. This suggests that mechanisms structuring invasive populations at the invasion front are different from those occurring in areas invaded for longer period. Participatory monitoring with local people may serve as a cost-effective early warning system to detect and control incipient invasive pest species in countries where the daily management of biological resources is largely in the hands of poor rural people. specialized Insect pest Developing countries Participative monitoring Farmer communities Education Andes 098 076 39 4 325-335 2010 0044-7447 https://www.documentation.ird.fr/hor/fdi:010052852 10.1007/s13280-010-0041-4 0044-7447 [F B010052852] https://www.documentation.ird.fr/hor/fdi:010052852 https://www.documentation.ird.fr/intranet/publi/2010/10/010052852.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-11-05 2026-02-16 fdi:010052852 fre
