Entomopathogenic nematodes and their associated bacteria comprise together highly pathogenic complex able to invade and kill insect host within two days. Both bacteria and nematodes produce variety of factors interacting with insect immune system that help to overcome host defences. These factors are specific for each of nematobacterial complexes leading to the differences in their pathogenicity. Moreover, we observed difference in pathogenicity also between two isolates of one nematobacterial complex, Steinernema carpocapsae – Xenorhabdus nematophila. Ability to invade and kill insect host is low in newly emerged nematodes and develops through the time reaching its maximum after three weeks in complex Heterorhabditis bacteriophora – Photorhabdus luminescens. Differences in pathogenicity were observed also among particular generations of nematodes released from insect cadaver. Nematodes collected at the beginning of emergence were less pathogenic than subsequent collections. From third week of collection further we did not detect any other significant changes in nematobacterial pathogenicity, which is then influenced only by the survival of nematodes. Data describing development of infectivity and pathogenicity of Heterorhabditis bacteriophora – Photorhabdus luminescens complex will be used to increase efficiency and reproducibility of experimental infections used to describe immune response of insect to the nematobacterial complexes. Our research was supported by the project KONTAKT II LH14047 and program CZ.1.07/2.3.00/30.0009 co-financed from European Social Fund and the state budget of the Czech Republic.
