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