Paper contains the literature review on the following subjects: - occurrence and spreading, - morphology of eggs, larvae and adults, - host plants and nutritive preferences, - biology, mainly development activity of adults and fertility of females, - methods of control.
Results of presented experiments indicated, that iron phosphate (III) protected plants of Hosta fortunei and Tagetes patula against damage caused by Iberian slug (Arion lusitanicus) and Whitelipped banded snail (Cepaea hortensis). This product showed very similar results to reference products based on metaldehyde and methiocarb.
Soil samples were collected from 10 plantations of tulip. The most often found plant-parasitic nematode was Pratylenchus neglectus, of which 80 species were found. But P. neglectus was usually not over 10% of the individuals in the samples. Among ectoparasitic nematodes, the most often found was Bitylenchus dubius. The occurrence of Bitylenchus dubius was not dependent on the acidity of the soil. Facultative parasites were the most numerous group, especially Filenchus vulgaris and Basiria graminophila. The plant-parasitic nematode populations which occurred on plantations of tulip did not cause severe damage.
