New records of insect herbivory on American cranberry in Finland

Introduction

New records of insect herbivory on american cranberry in finland. Discover new records of Aphis fabae (aphid) and eight lepidopteran species (moth larvae) feeding on American cranberry crops in Finland. Learn about these potential pests and their economic importance for Finnish growers.

Abstract

American cranberry (Vaccinium macrocarpon) is a native North American fruit crop, cultivated mainly in a small number of countries, including the USA, Canada, Chile in the New World, and Türkiye, Germany, Belarus, Poland and Sweden in Eurasia. In Finland, experimental and commercial cultivation of American cranberries has recently been initiated, developing new technology for soilless table-top cultivation in high plastic tunnels. Here we report, for the first time, that Aphis fabae, a polyphagous aphid and eight species of lepidopterans (moth larvae) feed on American cranberry plants in Finland. Six species of lepidopterans belong to the family Noctuidae (Lacanobia contigua, Lacanobia oleracea, Xestia baja, Anarta trifolii, Xanthia togata and Amphipyra pyramidea) and two species to the family Geometridae (Biston betularia and Hypomecis roboraria). These insects may become pests of economic importance to Finnish producers. All insects reported in this study have established populations in Finland, feeding on many deciduous trees and herbaceous grasses. The proximity of landscapes containing such plants might have influenced the migration of these insects into the cranberry crop.
