The potential use of entomopathogenic nematodes against Typhaea stercorea
BioControl 45 (1), 97-111
Abstract: Four entomopathogenic nematode species, Steinernemacarpocapsae, S. feltiae, Heterorhabditis bacteriophoraand H. megidis, were tested in a petri dish assay againstlarvae and adults of the hairy fungus beetle Typhaea stercorea. In general, adults were lesssusceptible than larvae and the LC50 decreasedwith the duration of the exposure to nematodes. S. carpocapsae was the most effective species againstadult beetles (LC50 after 96 hours exposure =67 nematodes/adult). Against larvae S.carpocapsae and H. megidis were comparablyeffective with an LC50 of 30 and 55nematodes/larvae, respectively. S. carpocapsaewas tested at 70 and 100% RH against adults in baitsof either chicken feed or crushed wheat, bothsupplemented with horticultural capillary mattingpieces in order to obtain a wet weight of 50-60%. At70% RH no significant effect of the nematodes wasobtained due to desiccation of the bait. In chickenfeed at 100% RH the mortality reached 80% with 500nematodes/adult. In wheat significant mortality wasobtained only at 5000 nematodes/adult. Heavy growth ofmould probably limited the nematode infection. Whenthe bait was used in tube traps, desiccation andgrowth of mould was prevented, but nematode efficacydropped to 4.4% in the traps and 12% in thesurrounding litter.
