Abstract

This paper presents historical information on the Danube huchen, Hucho hucho (L.), in Polish sources from the sixteenth to early twentieth centuries in the Danube, Prut, Dniester, and Vistula river basins. These accounts concern the historical distribution of the species and its economic importance, culinary value, fishing methods, and artificial reproduction and propagation. The occurrence of huchen in the Dniester River basin until the beginning of the eighteenth century merits special interest, because this river is not mentioned by any modern source on the natural distribution of this species. The extinction of the huchen in this river can likely be attributed to anthropogenic changes in the environment that were associated mainly with agricultural development.

Abstract

This is the first report on the occurrence of andromeda lace bug, Stephanitis (Stephanitis) takeyai Drake and Maa, 1955, and rhododendron lace bug, Stephanitis (Stephanitis) rhododendri Horvath, 1905, in Slovakia. Syntopic colonies of both species were found on rhododendron shrubs (Rhododendron sp.) in south-western Slovakia in 2015. The feeding of the lace bugs resulted in damage to infested rhododendrons. Leaves turned yellow and brown, prematurely dropped what led to continuous drying up of twigs and the whole plants. Details on morphology of adult stages of the two species, description of damage symptoms and economic importance of these pests are presented and discussed.

Abstract

The Ligurian leafhopper (Eupteryx decemnotata Rey 1891) has been recorded for the first time in Poland, in a commercial greenhouse in Warsaw. Individuals were collected from rosemary (Rosmarinus officinalis L.). Intense feeding of this species caused serious damage in the cultivation of rosemary. For this reason, the range extension of this species must be monitored.
