“…Beside 2-heptanone secreted by B. nematocida, several nematophagous fungi have also been found to produce attractive materials. For example, the nematode-trapping fungus Monacrosporium rutgeriensis could produce three different compounds that attract the saprophytic nematode, P. redivivus [63]. Furthermore, the traps produced by several nematode-trapping fungi make these fungi more attractive to nematodes than those without traps [64].…”

Plant-parasitic nematodes (PPNs) cause severe damage to agricultural crops worldwide. As most chemical nematicides have negative environmental side effects, there is a pressing need for developing efficient biocontrol methods. Nematophagous microbes, the natural enemies of nematodes, are potential biocontrol agents against PPNs. These natural enemies include both bacteria and fungi and they use diverse methods to infect and kill nematodes. For instance, nematode-trapping fungi can sense host signals and produce special trapping devices to capture nematodes, whereas endo-parasitic fungi can kill nematodes by spore adhesion and invasive growth to break the nematode cuticle. By contrast, nematophagous bacteria can secrete virulence factors to kill nematodes. In addition, some bacteria can mobilize nematode-trapping fungi to kill nematodes. In response, nematodes can also sense and defend against the microbial pathogens using strategies such as producing anti-microbial peptides regulated by the innate immunity system. Recent progresses in our understanding of the signal pathways involved in microbe–nematode interactions are providing new insights in developing efficient biological control strategies against PPNs. This article is part of the theme issue ‘Biotic signalling sheds light on smart pest management'.

“…It has been confirmed that the attractants of A. dactyloides, A. oligospora, A. conoides, and M. rutgeriense were different from the nematode-killing compounds. [42][43][44][45] The attractants in the nematophagous fungi are thought to be volatile chemicals or a volatile substance, but no chemical components have been identified thus far. Because the chemotaxis-changing substance might not be the attractant, we were unable to conclude that snodprot can attract nematodes.…”
