Orientation of Heterorhabditis megidis to insect hosts and plant roots in a Y‐tube sand olfactometer

Abstract: The host-searching behaviour of Heterorhabditis megidis strain NLH-E 87.3 in the presence of insect hosts and plant roots, offered individually and in combination, was studied using a newly developed Y-tube olfactometer filled with sand. Within a period of 24 hours infective juveniles (IJs) were significantly attracted to living G. mellonella larvae and caused 100% larval mortality. Otiorhynchus sulcatus larvae, however, did not elicit hostoriented movement of IJs and no larval mortality was observed. Roots of… Show more

“…For example, Neoseiulus cucumeris female predatory mites of rust mites (Aceria tulipae) responded to belowground volatiles signals of tulip bulbs infested by A. tulipae but not to volatiles of untreated or wounded bulbs (Aratchige, Lesna, and Sabelis 2004). Two inspiring papers demonstrated for the first time that unknown emissions of odorous cues were responsible for attracting entomopathogenic nematodes to insect damaged roots (Boff, Zoon, and Smits 2001;van Tol et al 2001). To date, few additional tritrophic interactions implying belowground VOCs signaling have been described both in agricultural systems Stelinski 2010, 2011;Rasmann et al 2005) and in wild environment (Rasmann et al 2011).…”

“…Roots alone are attractive (Bird and Bird, 1986;Kanagy and Kaya, 1996;Hui and Webster, 2000), and even more so when they are wounded or fed on by insects (Wang and Gaugler, 1998;Boff et al, 2001;van Tol et al, 2001;Rasmann and Turlings, 2008). The presence of roots in soil enhanced the rate of infection by EPN of non-feeding trap insects (wax moths), but only at low root density (Choo and Kaya, 1991), while high density of roots interfered with host-finding (Choo et al, 1989).…”

“…The induced emission of chemical signals is not limited solely to aboveground plant parts. The entomopathogenic nematode Heterorhabditis megidis was found to be attracted to exudates emitted by plant roots after damage by weevil larvae 9,10 , but the nature of the attractants involved is unknown. Here we show that maize roots damaged by larvae of the economically important coleopteran pest Diabrotica virgifera virgifera LeConte are attractive to entomopathogenic nematodes, and we identify the chemical compound responsible for the attraction.…”
