First Collection Records of \u3ci\u3eHippodamia Variegata\u3c/i\u3e (Coleoptera: Coccinellidae) in Minnesota Corn and Soybean

The coccinellid Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) is a relatively recent addition to the North American coccinellid fauna. This species was first reported in 1984 near Montreal, Quebec (Gordon 1987). Since then, its range has expanded beyond northeastern North America with the newest records in the midwestern United States, including Michigan (Gardiner and Parson 2005), Ohio (Pavuk et al. 2007), Wisconsin (Williams and Young 2009), and most recently South Dakota (Hesler and Lundgren 2011). Here we provide the first records of H. variegata in Minnesota. In addition, our records further define the movement pattern of this beetle across the Midwest by documenting its presence in the gap between Wisconsin and South Dakota

Flash floods and debris flow in the city area of Messina, north-east part of Sicily, Italy in October 2009: the case of the Giampilieri catchment

Abstract. This paper concerns the analysis of the 1 October 2009 flash flood and debris flow event caused by a very intense rainfall concentrated over the Messina area. The storm caused severe flash floods in many villages around the city of Messina, such as Giampilieri, Scaletta Zanclea, Altolia Superiore and Molino, with 38 casualties and significant damages to property, buildings, roads and bridges estimated close to 550 million Euro. The main focus of this work is to perform a post event analysis, putting together available meteorological and hydrological data in order to get better insight into temporal and spatial variability of the rain storm, the soil moisture conditions and the consequent flash flood in the Giampilieri catchment. The event was investigated using observed data from a raingauge network. Statistical analysis using GEV distribution was performed and rainfall return period (storm severity) was estimated. Further, measured rainfall data and rainfall-runoff modelling were used to estimate soil moisture conditions, to analyse the hydrological behaviour and to reconstruct flood hydrograph. With the help of GIS technology and particularly spatial analysis, the volume of debris which has gone down into the Giampilieri village was also calculated. GIS maps with landslide and material deposit areas were produced and analysed.</p
