Sensitivity of Hylobius abietis (L.) larvae on native species and isolates of entomopathogenic nematodes

The use of entomopathogenic nematodes (Steinernema and Heterorhabditis spp.), against the large pine weevil Hylobius abietis (L.) is currently studied in many countries. They show a great potential of nematodes for H. abietis control in laboratory and field experiments. In 2011 similar studies began in Poland to develop new biological control method of H. abietis with the use of native isolates of the nematodes. The first laboratory stage of the experiments pointed at the estimation of biological activity of 3 native isolates: 2 of Steinernema feltiae (Filipjev) and 1 of S. kraussei (Steiner).
