The use of the mix Mospilan is endangering the non-target species of the crown fauna. By the method of shedding to sails were observed species Quercus petraea, Quercus robur, Betula pendula, Fagus sylvatica, Carpinus betulus, Larix decidua, Pinus sylvestris, Robinia pseudoacacia, Tilia spp. in June – August period. The control samples in fortnightly interval, one-off sample 100-150 pieces (woody plant/term), conservation 75% ethanol, sorting in lab, determination in cooperation with specialists.

The predation component represented 33,5 %, overall the most numerous was the species Araneae. The minority was represented by Coccinellidae, Carabidae, Diplopoda a Chilopoda. In mid-May, the pseudocaterpillar were in the crown fauna, Curculionidae and caterpillars of Lepidoptera were in the crown fauna at the start of vegetation period. Critical stages of Panolis flammea were found during the check in 2018.
