“…The factors causing this effect resulted from olfactory cues (the difference in the amounts of volatiles from 16 and four uninfested plants), visual cues or both. The synergistic roles of uninfested plant volatiles on the response of predatory mites and parasitoid wasps to host‐ and/or prey‐induced plant volatiles have been reported (Büchel et al., ; de Boer & Dicke, ; Mumm & Hilker, ; Van Wijk et al., ). For example, Mumm and Hilker () showed that the egg parasitoid Chrysonotomyia ruforum responds to ( E )‐β‐farnesene only when coupled with a background odour of undamaged pine volatiles.…”

“…In their habitat, however, infested plants exist among conspecific and/or heterospecific uninfested plants. In fact, the foraging behaviour of parasitoid wasps and predators mediated by host‐ and/or prey‐infested plants is affected by the presence of uninfested plants (Büchel et al., ; de Boer & Dicke, ; Mumm & Hilker, ; Van Wijk, de Bruijn, & Sabelis, ). For example, Van Wijk et al.…”

“…infested plants exist among conspecific and/or heterospecific uninfested plants. In fact, the foraging behaviour of parasitoid wasps and predators mediated by host-and/or prey-infested plants is affected by the presence of uninfested plants (Büchel et al, 2014;de Boer & Dicke, 2004;Mumm & Hilker, 2005; Van Wijk, de Bruijn, & Sabelis, 2011). For example, Van Wijk et al (2011) showed that volatiles from the freshly excised leaf discs of noninfested lima bean that elicited no behavioural response from Phytoseiulus persimilis, a predatory mite of spider mites of the genus Tetranychus, contributed to the attractiveness of Tetranychus urticae-infested lima bean leaf volatiles for P. persimilis.…”

A blend of four volatile compounds, (Z)‐3‐hexene‐1‐yl acetate, α‐pinene, sabinene and n‐heptanal, emitted from cabbage plants infested by diamondback moth (DBM) larvae (hereafter called the attractant) attract females of Cotesia vestalis, a dominant parasitoid wasp species of DBM larvae. Here, we tested the effects of the presence of uninfested komatsuna (Brassica rapa var. perviridis L. cv. Rakuten) plants on the wasps’ response to the attractant in the choice chamber under laboratory conditions. Satiated female wasps were equally distributed between groups of 16 and four uninfested plants. However, the wasps preferred the group of 16 uninfested plants with the attractant to that of four uninfested plants with the attractant, indicating that the greater biomass of uninfested plants synergistically increased the attractiveness of the attractant. The effects of honey (a food of C. vestalis while rearing) on the wasps’ responses to the attractant were also tested using starved females. The wasps showed an equal distribution between honey with four uninfested plants and four uninfested plants. When both odour sources were coupled with the attractant, the wasps significantly preferred the former odour source, indicating a synergistic effect of honey on the attractiveness of the attractant. This effect, however, was observed when C. vestalis females had been reared with the tested honey but not when they had been reared with aqueous sucrose. In the experimental glasshouse, when comparing a group of infested plants coupled with uninfested plants, honey and the attractant to a group of infested plants, female wasps preferred the former. In addition, this preference was significantly greater than their preference for infested plants coupled with the attractant over infested plants. Thus, there was a synergistic effect of uninfested plants and honey on the attractiveness of the attractant–infested plant complex under glasshouse conditions.

“…In conclusion, the odor background can affect responses to target odors (e.g., Büchel et al, 2014 ). Thus, for example, efficient odor baits developed in the laboratory could fail to attract insects under field conditions, where different background odors are present.…”

Neuroethology of Olfactory-Guided Behavior and Its Potential Application in the Control of Harmful Insects

Harmful insects include pests of crops and storage goods, and vectors of human and animal diseases. Throughout their history, humans have been fighting them using diverse methods. The fairly recent development of synthetic chemical insecticides promised efficient crop and health protection at a relatively low cost. However, the negative effects of those insecticides on human health and the environment, as well as the development of insect resistance, have been fueling the search for alternative control tools. New and promising alternative methods to fight harmful insects include the manipulation of their behavior using synthetic versions of “semiochemicals”, which are natural volatile and non-volatile substances involved in the intra- and/or inter-specific communication between organisms. Synthetic semiochemicals can be used as trap baits to monitor the presence of insects, so that insecticide spraying can be planned rationally (i.e., only when and where insects are actually present). Other methods that use semiochemicals include insect annihilation by mass trapping, attract-and- kill techniques, behavioral disruption, and the use of repellents. In the last decades many investigations focused on the neural bases of insect's responses to semiochemicals. Those studies help understand how the olfactory system detects and processes information about odors, which could lead to the design of efficient control tools, including odor baits, repellents or ways to confound insects. Here we review our current knowledge about the neural mechanisms controlling olfactory responses to semiochemicals in harmful insects. We also discuss how this neuroethology approach can be used to design or improve pest/vector management strategies.

“…Sabidamente, os odores do habitat podem maximizar a resposta dos parasitoides aos compostos exclusivos do hospedeiro, ou então, mascarar a fonte de odor, resultando em um efeito inibitório ou mesmo repelente (AZEEM et al, 2015;BEYAERT et al, 2010;BÜCHEL et al, 2014;FÜRSTENAU et al, 2016;MUMM;HILKER, 2005;SCHRÖDER;HILKER, 2008).…”
