Quickscan Contarinia sp. in Alstroemeria
This Quickscan was prompted after the finding of a gall midge in an Alstroemeria crop grown for the production of cut flowers in a glasshouse in the Netherlands in July 2016. The gall midge was diagnosed as Contarinia sp. and may be a new yet undescribed species. The origin of the outbreak is unknown. Flower buds were heavily damaged and no marketable cut flowers could be harvested from affected plants. The grower has taken measures to eradicate the gall midge from the glasshouse. It is currently unknown if the gall midge can survive outdoors in the Netherlands.
