【 摘 要 】

The rose flea beetle, RFB (Luperomorpha xanthodera Fairmaire 1888) is a new flower pest inEurope. In 2012, it was brought accidentally to central Poland. To search for this introducedspecies in the area adjacent to the site of the first finding, 29 plant species belonging tofive botanical families (Lamiaceae, Brassicaceae, Asteraceae, Plantaginaceae, Crassulaceae)were monitored over a 3-year-long study (2016−2018). RFB were found on 11 herbaceous/ornamental plant species (Lamiaceae, Brassicaceae, Asteraceae) along with feeding damageto the flowers. White mustard (Sinapis alba L., Brassicaceae), hyssop (Hyssopus officinalisL.), and Monarda spp. (Lamiaceae) were its most preferred host plants. In each season, RFBfemales preferred host plants which bloomed abundantly and vividly. However, among theexamined plant species there was a large variation in the year-to-year RFB abundance. Overthe examined period the RFB extended its abundance exponentially, and its populationsurvived and established itself in the area. The general sex ratio of the beetles was stronglyfemale biased. In the female pool, females with conspicuously swollen abdomens predominated.The results of our study provide more insight into RFB behaviour, its establishmentand spreading into new areas. To support the evidence for the RFB risk factor as an agricultural/horticultural pest, further research should focus on the beetles’ biology, reproductivetactics, larval host plant preference, larva-inflicted damage and harmfulness, the impact ofthe RFB on the native fauna, as well as its further local and distant migration propensity.Presently our knowledge about these aspects is still fragmentary.
