ABSTRACT


There were performed an experiments with entomopathogenic nematodes of four species: Heterorhabditis bacteriophora, Heterorhabditis megidis, Steinernema feltiae and Pharmarhabditis hermaphrodita that were subjected to the liquid static pressure of 52.5 MPa. The static pressure was intermitted. The times of interval and compressive periods were equal 1 minute. The duration of each experiment was 30 minutes. There were counted a relative viability of nematodes before and after treatment. It was not observed that the intermitted pressure, caused death of the nematodes.

Key words: Entomopathogenic nematodes, biopesticides, liquid pressure.
