“…Methyl salicylate has been reported as an aphidrelated compound in a number of different crop plants (Zhu & Park 2005;Sasso et al 2007) and, not surprisingly, it is recognized by the aphid parasitoid A. ervi even at a concentration as low as 0.01 mg/ml (Sasso et al 2009). When applied as vapor, this compound showed a significant negative effect on aphid fixing behaviour and fertility in accordance with previous studies in the olfactometer (Hardie et al 1994;Glinwood et al 2007).…”

“…This compound has been reported to be repellent for the aphids Sitobion avenae (Bruce et al 2003) and Aphis gossypii (Moraes et al 2009) but highly attractive towards the aphid parasitoid A. ervi (Birkett et al 2000;Sasso et al 2009). These contrasting results can only be explained by a specific plant-mediation.…”

“…In the system consisting of tomato, Solanum lycopersicum (L.), the aphid Macrosiphum euphorbiae (Thomas) and its natural enemy, the endophagous parasitoid Aphidius ervi (Haliday), the profile of the VOCs released by tomato plants following aphid infestation has been quantified and characterized (Sasso et al 2007). Such VOCs were subsequently tested for olfactory recognition (EAG) and parasitoid attractiveness (wind tunnel bioassay), and a final 'chart' was compiled on the basis of the combined results (Sasso et al 2009). All these observations were restricted to the highest level of the trophic chain, i.e.…”

In the tritrophic system consisting of tomato, Solanum lycopersicum (L.), the aphid Macrosiphum euphorbiae (Thomas) and its natural enemy, the parasitoid Aphidius ervi (Haliday), it has been shown that the release of volatile organic compounds following aphid attack is responsible for attracting aphid parasitoids in wind tunnel experiments. The main compounds involved in these multitrophic interactions have been characterized and quantified. In this work, the possible activity of such compounds on plant direct defences against the aphid M. euphorbiae was assessed in laboratory tests. The selected compounds were applied to uninfested tomato plants, either by evaporation or contact, and performance of aphids, in terms of plant acceptance, fixing behaviour and aphid development, calculated in standard conditions. The results showed that two compounds, namely methyl salicylate and cis-hex-3-en-1-ol, alter aphid performance. These two compounds have been reported to be those eliciting the best response by A. ervi in terms of flight behavior (wind tunnel bioassay) and antennal stimulation (EAG bioassay).

“…In this view, we tried to assess the attractiveness for parasitoids of GM tomato plants with respect to control plants. No differences in the flight behavior of this parasitoid were found, and since the response of A. ervi remained unchanged, we therefore hypothesize that the volatile profile of the Cry3Bb expressing tomato plants was not different from conventional plants in relation to plantÁparasitoid interactions, at least for those compounds involved in the foraging behavior of A. ervi (Sasso et al 2009). This hypothesis was reinforced by the fact that the values of attractiveness recorded for our Bt tomato plants were very similar to those reported for different (not infested) cultivars of tomato, namely M82 (30%, Guerrieri et al 2004), Better Boy (20%, Corrado et al 2007) and UC82 (20%, Sasso et al 2007).…”

Bacillus thuringiensis Berliner toxins are highly specific in terms of insect pest targeted. For example, Cry3Bb is active against Coleoptera. As a consequence, in the framework of using genetically modified plants expressing different Bt toxins in sustainable agriculture, there is a growing interest about the impact of these crops on the environment and on non-target organisms. The effects of genetically modified Bt-tomato plants expressing the toxin Cry3Bb on the aphid Macrosiphum euphorbiae (Thomas) and its natural enemies, the generalist predator Macrolophus caliginosus Wagner and the endoparasitoid wasp Aphidius ervi Haliday, were assessed under laboratory conditions. No significant differences between performance of M. euphorbiae were observed on genetically modified tomato plants (line UC82Bt) with respect to their near-isogenic control line (line UC82). Immunoassays did not detect Cry3Bb protein in M. euphorbiae developing on Bt-expressing tomato plants. Similarly, no significant differences were found on the longevity and prey consumption of M. caliginosus when fed aphids reared on UC82Bt or on UC82. Moreover, the genetic modification did not affect the attractiveness of uninfested tomato plants toward A. ervi. It is therefore concluded that Cry3Bb-expressing tomato plants did not show any acute adverse effects on the biological parameters of the non-target herbivore M. euphorbiae or its natural enemies, M. caliginosus and A. ervi, under laboratory conditions.

Societal Impact StatementArbuscular mycorrhizal fungi (AMF) impact the relationships between plants, aphids (insects that feed on plant phloem), and their natural enemies (insects that prey on or parasitize aphids). The presence of AMF influences the growth and population of different aphid species and affects the development of aphid‐killing wasps and their attraction to plants. This research has been conducted also considering the insects' feeding strategy and their feeding specialization. This study provides novel perspectives on how these fungi shape interactions in the natural world, offering potential insights for the development of sustainable pest management strategies in agriculture.Summary Arbuscular mycorrhizal fungi (AMF) are major root symbionts regulating plant physiology. Their presence affects the performance of aboveground insect herbivores in relation to their feeding strategy and their feeding specialization. For example, the effect of the arbuscular mycorrhizal (AM) symbiosis on chewing insects, positive for specialists and negative for generalists, has been previously demonstrated. Conversely, the impact of AMF on phloem‐suckers with relatively different levels of specialization remains unexplored. We tested the influence of the AM Funneliformis mosseae on the fitness of the specialist aphid Acyrthosiphon pisum and the generalist aphid Myzus persicae on Vicia faba plants. Further, we investigated the effects of AMF on the higher trophic level, the aphid parasitoids Aphidius ervi (specialist) and Aphidius colemani (generalist), by evaluating plant attractiveness and parasitoid fitness. To support the results of behavioral and biological bioassays we characterized the photosynthetic parameters, the volatilome and the transcriptome of tested plants. Mycorrhizal plants proved unsuitable for the generalist M. persicae but enhanced the fitness of the specialist A. pisum. The AM symbiosis had no effects on the behavioral response of A. colemani and enhanced the attraction and fitness of A. ervi. Volatilome and transcriptome profiling corroborated the results of bioassay highlighting a bottom‐up effect of the AMF across a plant–aphid–parasitoid system.
