Pheromone-based monitoring of invasive alien insects along the border of Finland and Russia – methods and unintentionally caught species

Global trade provides pathways for the spread of invasive species. To tackle threat, many countries have designated surveys that are typically conducted at probable ports entry. For Finland, most north-eastern region European Union (EU), such site is border with Russia and imports coniferous roundwood wood chips. In this paper, we describe monitoring systems based on pheromone-trapping three EU-wide quarantine pests: Dendrolimus sibiricus, Polygraphus proximus Bursaphelenchus xylophilus. We also list non-target species caught in an exploratory survey using pheromone traps. During years survey, no pests were detected, but 30 other insects caught. Therefore, – despite not detecting target provided information about abundance As insect diversity reflects status surrounding environment, value data should be increased via co-operation among research institutes.
