“…Further work in this area will include screening for the key odours involved in M. cingulum attraction, and using mutants and transgenic maize with different levels of volatile emissions to investigate the biosynthesis, metabolic engineering and function of O. furnacalis-induced maize volatiles. Moreover, field studies are needed in order to reveal the role of plant volatiles in determining the population dynamics of pests and their natural enemies, because the responses of natural enemies to HIPVs are more complex in real agricultural settings than in the laboratory (Salamanca et al, 2017).…”

The Asian corn borer (Ostrinia furnacalis Guenée) is a destructive pest of maize (Zea mays L.). Despite large-scale commercial maize production, little is known about the defensive responses of field-grown commercial maize to O. furnacalis herbivory, and how these responses result in direct and indirect defence against this pest. To elucidate the maize transcriptome response to O. furnacalis feeding, leaves of maize hybrid Jingke968 were infested with O. furnacalis for 0, 2, 4, 12 and 24 h. Ostrinia furnacalis feeding elicited stronger and more rapid changes in the defence-related gene expression (i.e. after 2 h), and more differentially expressed genes (DEGs) were up-regulated than down-regulated at all times post-induction (i.e. 2, 4, 12 and 24 h) in the O. furnacalis pre-infested maize plants. KEGG pathway analysis indicated that the DEGs in the O. furnacalis pre-infested maize are involved in benzoxazinoids, phytohormones, volatiles, and other metabolic pathways related to maize resistance to herbivores. In addition, the maize leaves previously infested by O. furnacalis for 24 h showed an obvious inhibition of the subsequent O. furnacalis performance, and maize volatiles induced by O. furnacalis feeding for 24 and 48 h attracted the parasitic wasp, Macrocentrus cingulum Brischke. The increased direct and indirect defences induced by O. furnacalis feeding were correlated with O. furnacalis-induced phytohormones, benzoxazinoids, and volatiles. Together, our findings provide new insights into how commercial maize orchestrates its transcriptome and metabolome to directly and indirectly defend against O. furnacalis at the mid-whorl stage in the field.

“…In the past 30 years, research has shown that herbivore feeding induces the production of volatiles from plants, commonly referred to as herbivore‐induced plant volatiles (HIPVs), and that, in turn, the natural enemies of herbivores can be attracted to these HIPVs during prey location . As a result, various synthetic HIPVs have been tested to manipulate natural enemy behavior in agro‐ecosystems . However, the use of HIPVs for this purpose has remained controversial because there is the risk of disrupting biological control by confusing the natural enemies instead of helping them during prey or host location, by possibly increasing ecological risks by unintentionally attracting the herbivores themselves, or by attracting the enemies of the natural enemies, for example hyperparasitoids, which in turn may reduce populations of the third trophic level.…”

“…abundance); (2) this attraction should reduce pest populations, thus enhancing natural enemy ecosystem function; and (3) a reduction of pest populations should cascade down to reduce damage and increase crop productivity, thus enhancing ecosystem services provided by the natural enemies. Several studies have shown that natural enemies are attracted to HIPVs in agro‐ecosystems (criterion 1) . For example, in an early study, Flint et al .…”

“…We tested this hypothesis in a system consisting of common bean ( Phaseolus vulgaris L.) plants, the HIPV MeSA, and coriander ( Coriandrum sativum L.) as a companion plant. Both MeSA and coriander have been shown to attract natural enemies of herbivores in agro‐ecosystems (see below). We predicted that MeSA and coriander would interact synergistically to alter the arthropod community, i.e.…”

BACKGROUND Biological control plays a key role in reducing crop damage by Tuta absoluta (Meyrick) and Trialeurodes vaporariorum (Westwood), which cause huge yield losses in tomato (Solanum lycopersicum L.). The mirid predator Nesidiocoris tenuis (Reuter) preys heavily on these pests, with satisfying control levels in tomato greenhouses. Although N. tenuis is known to be attracted to volatiles of tomato plants infested by T. absoluta and whitefly, little is known about the specific attractive compounds and the effect of prey density on the predator response. RESULTS Y‐tube olfactometer bioassays revealed that the attraction of N. tenuis to tomato volatiles was positively correlated with the density of T. absoluta infestation, unlike T. vaporariorum infestation. The predator was also attracted to volatiles of T. absoluta larval frass, but not to T. vaporariorum honeydew or T. absoluta sex pheromone. Among the herbivore‐induced plant volatiles (HIPVs) that characterised the attractive plants infested with 20 T. absoluta larvae, olfactometer bioassays revealed that N. tenuis is attracted to the monoterpenes α‐pinene, α‐phellandrene, 3‐carene, β‐phellandrene and β‐ocimene, whereas (E)‐β‐caryophyllene was found to repel the predator. In dose–response bioassays, the five‐component blend of the attractants elicited a relatively low attraction in the predator, and removal of β‐phellandrene from the blend enhanced the attraction of the predator to the resulting four‐component blend, suggesting synergism among four monoterpenes. CONCLUSION These findings suggest that a four‐component blend of α‐pinene, α‐phellandrene, 3‐carene and β‐ocimene could be used as a kairomone‐based lure to recruit the predator for the biological control of T. absoluta and T. vaporariorum.
