Abstract

Four entomopathogenic nematode species, Steinernema carpocapsae, S. feltiae, Heterorhabditis bacteriophora and H. megidis, were tested in a petri dish assay against larvae and adults of the hairy fungus beetle Typhaea stercorea. In general, adults were less susceptible than larvae and the LC50 decreased with the duration of the exposure to nematodes. S. carpocapsae was the most effective species against adult beetles (LC50 after 96 hours exposure = 67 nematodes/adult). Against larvae S. carpocapsae and H. megidis were comparably effective with an LC50 of 30 and 55 nematodes/larvae, respectively. S. carpocapsae was tested at 70 and 100% RH against adults in baits of either chicken feed or crushed wheat, both supplemented with horticultural capillary matting pieces in order to obtain a wet weight of 50-60%. At 70% RH no significant effect of the nematodes was obtained due to desiccation of the bait. In chicken feed at 100% RH the mortality reached 80% with 500 nematodes/adult. In wheat significant mortality was obtained only at 5000 nematodes/adult. Heavy growth of mould probably limited the nematode infection. When the bait was used in tube traps, desiccation and growth of mould was prevented, but nematode efficacy dropped to 4.4% in the traps and 12% in the surrounding litter.
