Abstract

Glischrochilus beetles as pests of raspberry and strawberry fruits in Latvia.

Abstract

Glischrochilus beetles, belonging to family Nitidulidae, subfamily Cryptarchinae usually are not traditional plant pests and some are even predaceous species, however other species may be vectors of fungi. In Latvia, several complaints about Glischrochilus beetles found in fruits of raspberries and strawberries have been received from growers during the last ten years, and the same observations have been made by author. The observations show that Glischrochilus beetles in raspberry and strawberry fruits become more common over time. In July 2018, Glischrochilus grandis beetles were found in each of six randomly selected ripened fruit collected from one Rubus idaeus plant of unknown cultivar at orchard of Institute of Horticulture, Krimūnu pagasts. Before 2018, Glischrochilus beetles damaging raspberry and strawberry fruits were incorrectly presumed to be "Glischrochilus hortensis". The recent spread of two alien species Glischrochilus grandis and Glischrochilus quadrisignatus in Latvia may be the cause of more frequent observations in these crops.
