The blowfly Lucilia sericata (Meigen, 1826) (Diptera: Calliphoridae) is the primary agent of cutaneous myiasis of sheep in northern Europe, southern Africa, Australia and New Zealand. As the application of chemicals has several disadvantages, alternative control measures of traumatic myiasis of livestock must be developed. In this study, the use of entomopathogenic nematodes (EPNs) as potential biocontrol agents against second instar larvae of Lucilia sericata was considered. The following nematode species were tested: Heterorhabditis bacteriophora (IS 5, HHU 1, Hmo1, HNC 1, HAZ 36, Hbrecon, HHU 2, HAZ 29, HHP 88, HHU 3, HHU 4 and HGua), Steinernema intermedia, NC513 strain of S. glaserii, S. anomali, S. riobrave, Steinernema sp. and 5 strains of S. feltiae (22, Vija Norway, HU 1, scp, and IS 6). None of the examined EPN species or strains showed larvicidal efficacy at 37°C (no killing effect was observed in the case of the two heat-tolerant strains - H. bacteriophora and S. feltiae) against L. sericata larvae. At lower temperatures (20°C and 25°C) only strainsof S. feltiae were found to be active. The overall odds ratios calculated for L. sericata maggots to contract S. feltiae nematode infection show significant (p < 0.05) effect only in the case of strains HU 1, 22 and IS 6. In the case of strains HU 1 and 22 parasitic forms of S. feltiae could be detected in the dead larvae of L. sericata. Strain IS 6 (and also Vija Norway at 20°C) penetrated and killed fly larvae, but only adult forms of the nematode occurred in the cadavers.
