“…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). Unexpectedly, on the tomato, this compound seemed to have no direct effect on aphid behavior and performance when sprayed on the plant, even though a lower number (but not significant) of fixed aphids were observed at the end of the assay.…”

“…San Marzano at the age of three weeks were transferred singly in a perspex cage (4.7 dm 3 ), together with 10 ml of a volatile pure compound spotted on filter paper (Glinwood et al 2007). Assuming the complete evaporation of VOC in the box, we obtained the following concentrations: cishex-3-en-1-ol 18.01 mM, b-caryophyllene 9.38 mM, (()-a-pinene 13.38 mM, methyl salicylate 16.42 mM, cis-jasmone 12.18 mM.…”

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 other plant-herbivore systems, various organic compounds produced in response to plant damage have been shown to affect plant defence and plant gene expression in neighbouring plants, deterring herbivores and attracting their natural enemies (Dicke et al 2003;Baldwin et al 2006). Two such compounds, methyl jasmonate and methyl salicylate cause reduced host acceptance by R. padi in barley, but with a different diurnal response pattern than allelobiosis induction as measured both by aphid responses and gene expressions Glinwood et al 2007). …”

Abstract. Methyl jasmonate (MEJA), a well-known herbivore-induced plant volatile, promotes plant defences against various stress factors. The aim of this study was to investigate the effects of different doses of exogenously applied MEJA on the population densities of wheat insect pests and their natural enemies by employing three sampling methods (direct visual sampling, sweep net, sticky traps) in 2012 and 2013 under semi-arid conditions. MEJA treatments had repellent effects on aphids (Hemiptera: Aphididae), phytophagous thrips species (Thysanoptera: Phlaeothripidae and Thripidae) and hoverfly species (Diptera: Syrphidae), whereas it was attractive to wheat stem sawflies (Hymenoptera: Cephidae), lady beetle species (Coleoptera: Coccinellidae) and Collyria coxator (Hymenoptera: Ichneumonidae). MEJA treatments had no effect on aphid parasitoids abundances (Hymenoptera: Braconidae). The experimental outcomes varied, depending on plant phenology and sampling method. MEJA treatment also led to reductions in wheat yield and plant height. MEJA treatment could be beneficial as a natural pest control tool when certain species are targeted.
