Bleicher Krisztina, Markó Viktor & Orosz András: Species composition of Cicada (Auchenorrhyncha) communities on the surrounding vegetation of apple orchards in Hungary - Kabóca közösségek hazai almásokban
136 NATURA SOMOGYIENSIS Material and methods The samples were collected by Malaise traps in the surroundings of three apple orchards in Hungary in years 1999 and 2000. In two investigated areas (Nyírtura and Szigetcsép) three Malaise traps were placed. One inside of the apple orchard, one in the adjacent woodland and one between the apple orchard and the woodland in the open, bushy edge vegetation (named edge). In Vámosmikola two Malaise traps were placed inside of the apple orchard, one in the adjacent woodland and two in the edge. In the present paper data of cicada species found in the surrounding vegetation are given. The faunal list of cicada species collected in the apple orchards is given by BLEICHER et al (2006). Malaise traps (TOWNES 1972) resembled a tent with four open sides and four fine, white mesh panels below a conical mesh top (size of the panels: 2 m high, 1.25 m wide, total area of the four panels: 10 m 2 ). The traps between the adjacent woodland and the orchard were placed at 20-25 m distance from the edge of the orchard. The traps were continuously operated from late April or early May to October and were emptied three times a week. The orchards located in different environments: there was a lowland area with flooded forest (Szigetcsép), a lowland area with agricultural fields (Nyírtura), and a hilly area with forests (Vámosmikola). The exact geographical co-ordinates of the orchards were as follows: Vámosmikola (Lat. 47° 58.4' N, Long. 18° 49.3' E) (two neighbouring, conventionally treated apple orchards), Szigetcsép (Lat. 47.0° 15.0' N, Long. 18° 58.3' E) (conventionally treated apple and pear orchards), Nyírtura (Lat. 48° 0.2' N, Long. 21° 49.5' E) (organic apple orchard). The resolution of geographic coordinate distribution is about 0.1 min in latitude and longitude. That means about 130 m and 200 m of accuracy in the E-W and N-S directions, respectively. The apple orchard in Szigetcsép was situated near by the river Danube. The vegetation of the woody area, which surrounded the orchard, was composed of Populus and Salix species, mainly P. tremula and S. alba, rarely P. alba, mainly with Sambucus nigra and Rubus caesius in the shrub layer. There were also other fruit orchards in the surrounding: pear, apricot, peach, cherry and sour cherry. The orchard in Nyírtura was surrounded by a plantation of Populus x canadensis. The orchard in Vámosmikola was surrounded by forests with Quercus species, mixed with Robinia pseudoacacia. Figure 1. The investigated areas on UTM map
