Abstract

To compare the efficiency of collecting methods by structural characterisation of a neuropteroid community the authors carried out an investigation in a commercial apple orchard at Szigetcsép by using three different trapping techniques, Malaise trap, suction trap and light trap. Considering of the individuals of this community, the suction trap seems to be the most useful sampling device outrunning the material caught by light trap and especially those of Malaise trap. During the investigation the suction trap and light trap show the numbers of the species and individuals of Coniopterygidae, Hemerobiidae and Chrysopidae families in a similar way. To record snake flies, Raphidiidae, Malaise trap seems to be the most suitable sampling device while the light trap is the best for sponge flies, Sisyridae. Abundance of Hemerobius humulinus and Wesmaelius subnebulosus was underestimated by Malaise trap compared with the records of suction trap; however Micromus angulatus and Micromus variegatus were overestimated by Malaise trap. Comparing the results of light trap to suction trap Hemerobius humulinus, Wesmaelius subnebulosus and Chrysoperla carnea complex were underrepresented while Micromus angulatus, Micromus variegatus, Chrysopa formosa and Chrysopa phyllochroma were overestimated. Diversity profiles drawn by different sampling techniques show that the diversity of the suction trap samples, except for the beginning of the scale parameter, is significantly (p < 0.01) lower in its total length from the values of light trap and Malaise trap. In the profile of plots of light trap and Malaise trap the diversity of the samples were not different in the species with medium and higher abundance. In conclusion, the sampling techniques used in the ecological investigations can determine the characteristics of neuropteroid communities. These results show that sampling devices have to be chosen cautiously according to the main aims and the interpretation of investigations.
