Pyemotes herfsi (Oudemans, 1936) as causative agent of another mass dermatitis in Europe (Acari, Pyemotidae).

The authors describe new cases of human dermatitis caused by Pyemotes herfsi occurring in the food mixing shed for the farrowing house in the piggery at a farm in the destrict of Olomouc, where seven persons handling feedstuff were infected. The disease became manifest as a papular rash, appearing particularly on the back, and all over the body except on the hands and face. When the afflicted person discontinued work in the feed mixing shed, the rash disappeared quickly. The mites were found in the granular dust accumulated in the loft above the food mixing shed. The initial host (insects) could not be identified. After cleaning and disinsecting the contaminated premises with Metation E 50 the workers were free from any symptoms. The mites of the genus Pyemotes, particularly the species P. herfsi (Oudemans, 1936) are little known, but probably frequent causative agents of human dermatitides.

Allergogenous mites (Acari: Pyroglyphidae) in private recreation houses.

The bed fauna of periodically inhabited dwellings markedly differs from the bed fauna in town apartments, both in quantity--a higher number of mites and quality--an important dominance of the species Euroglyphus maynei which makes up 70.4% of mites in country cottages, but only 28% in town apratments used by the owners of such recreation houses. In other apartments it is very rare. There differences are explained by the specific regime of humidity and temperature in the periodically inhabited rooms. The patients' worsening condition is apparently caused by quantitative changes.

Application of Bathurin and borax in the biological control of Monomorium pharaonis in housing estates.

Of two apartment houses infested with ants of the species Monomorium pharaonis, one was treated with a biological, the other with a chemical substance. In the first case we used Bathurin in combination with borax at a concentration of 1.3% for both substances. In the first week, borax was added to the bait (minced beef), within the next three weeks, the bait was mixed with Bathurin. The procedure was repeated 5 times. After this period, we achieved complete control of the ants on the infested premises.--Our results obtained with the chemical substance (the insecticide Anthrix) were less successful. This indicates that the first method, although time-consuming and requiring a perfect collaboration with all inhabitants, is safer, because it leads to the complete eradication of ants in the infested premises.
