Population dynamics of the leafhopper Psammotettix alienus Dahlb. and two-year investigations into the occurrence of Wheat dwarf virus (WDV) in crops of winter barley located in the Middle German Dry Region, Germany
From 2000 to 2001 the population dynamics of Psammotettix alienus Dahlb. were recorded using a sweep-net or a biocoenometer. The investigations were carried out in Zscherben near Halle (Middle German Dry Region). The imagines of the first generation of P. alienus could be observed for the first time...

| description | From 2000 to 2001 the population dynamics of Psammotettix alienus Dahlb. were recorded using a sweep-net or a biocoenometer. The investigations were carried out in Zscherben near Halle (Middle German Dry Region). The imagines of the first generation of P. alienus could be observed for the first time at the beginning of May (2000) and at the end of May (2001), respectively. According to our results, in this area three generations of P. alienus are developed. In both years of our observations the barley-strain of Wheat dwarf virus (WDV) occurred. The main important infections appeared in autumn. Furthermore, during the whole period of our investigations the percentage of viruliferous individuals which were caught was recorded by means of a biological test. In June this percentage achieved 84.0% (2000) and 76.7% (2001), respectively. In the course of summer months of both years the percentage of viruliferous P. alienus decreased. In autumn of the year 2000 an increasing portion followed once again. However, in the year 2001 a continual reduction from > 70% in June to < 5% in late autumn could be observed. |
