Adults of Green hawker were collected in light traps in the valley of the river Narewka in Białowieża village, NE Poland (2006-07-22, 1 ♀ at mercurial lamp and 2006-07-23, 3 ♀♀ and 1 ♂ at arclamp). All specimens were caught on ca 2140. The collected individuals were sitting frontally to the lamp so that their body axes were forwardly directed to the source of light. The authors discuss the known cases of light-trapped dragonflies, especially in the zone of temperate climate and in Europe. This phenomenon can be the result of spontaneous activity of dragonflies or their arousal to activity by strong light. Up-to- date observations have shown that there are two possible explanations: in particular cases the first or the second mechanism was involved. For the observations from Białowieża more possible is the second one: Aeshna viridis was multiply found in the valley of the Narewka River, also at the sites where light traps were provided. It seems that many cases of dragonflies attracted to the light source are overlooked for odonatologists do not use the method and other entomologists who set light traps are not interested in dragonflies or underestimate such observations. So for gathering more data on the subject the cooperation of odonatologists and specialists of other insect groups is needed.
The objective of the research was to assess the presence of mycotic microbiota on the integument of wild boars and roe-deer, as well as to isolate and identify each species. The research material comprised groin screening swabs collected from 13 wild boars and 56 roe-deer from the Lublin State Forests. The fungi were identified concurrently on the Sabouraud and MLNA medium at 25°C, 32°C and 37°C temperature for 14 days. Initial identification proceeded according to the conventional mycological procedures followed by the application of the commercial API Candida and API 20C Aux (bioMerieux) (Candida genus) tests and the phenotypic scheme developed by Guillot et al. (Malassezia genus). The present research has revealed that mycotic flora was recovered in all a total of 69 examined animals. The most frequently isolated fungi included Penicillium spp., Alternaria spp., Cladosporium spp. and Malassezia spp. and Rhodotorula spp. The species analysis of the isolated fungi has confirmed the presence of potential pathogens, such as Malassezia sympodialis, Aspergillus fumigatus and Candida non-albicans. The obtained results indicate that a population of free-living animals may constitute a critical link in the epidemiologic chain of mycotic infections.
