“…To our knowledge, this is the first olfactory study of N. tenuis and D. maroccanus, but not for M. pygmaeus. Our results for M. pygmaeus are consistent with previous results (Moayeri et al 2006;Ingegno et al 2011). In our work, mirids were in contact with a pepper plant during 24 h before starvation; hence, learning behavior related to plant odor could be included.…”

In recent years, biological control strategies to control many major horticultural pests have been successfully implemented in the Eastern Mediterranean basin. However, the management of some pests, such as aphids in sweet pepper crops, can still be improved. The goal of this study was to examine the potential of the omnivorous predatory mirids Nesidiocoris tenuis, Macrolophus pygmaeus, and Dicyphus maroccanus as biocontrol agents of aphids in sweet pepper crops. First, the capacity to detect Myzus persicae-infested and un-infested plants was studied in a Y-tube olfactometer. Females of the three species of predatory mirids were strongly attracted to the odor of infested M. persicae plants. Second, the prey suitability of young and mature nymphs of M. persicae for these three mirid species was studied. The three species actively preyed on M. persicae, although D. maroccanus resulted the most voracious species preying both young and mature nymphs. Finally, the capacity of the three omnivorous predators to reduce M. persicae in heavily infested plants was determined in semi-field conditions. The three species of mirids could reproduce on aphids and establish on sweet pepper plants. Mirids significantly reduced the number of M. persicae per leaf, reaching levels of aphid reduction close to 100 % when compared to the untreated control. These results suggest that mirids might play a major role in aphid management in sweet peppers. The potential implementation methods of predatory mirids for the biological control in sweet peppers are discussed.

“…1b). In our previous study on the odour‐mediated preference of M. caliginosus between T. urticae and M. persicae on sweet pepper (Moayeri et al. 2006a) conducted under similar conditions we demonstrated that the mirids significantly preferred prey‐infested plants to clean plants, irrespective of the prey species.…”

“…In previous experiments we conducted a comparative study between the direct prey preference and the odour‐mediated preference M. caliginosus between the two‐spotted spider mite and the green peach aphid Myzus persicae (Sulzer) (Hom., Aphididae). We demonstrated a significant response of the mirid to pepper plants infested with M. persicae vs. clean plants and also to pepper plants infested by T. urticae over uninfested pepper (Moayeri et al. 2006a).…”

For example, when green beans ( Phaseolus vulgaris L.) or sweet pepper ( Capsicum annuum L.) are attacked by the two‐spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae), volatile blends emitted by the infested leaves attract the predatory mirid bug Macrolophus caliginosus Wagner (Het., Miridae) (Moayeri et al. 2006a,b).…”

Plants infested with a single herbivore species can attract natural enemies through the emission of herbivoreinduced plant volatiles (HIPVs). However, under natural conditions plants are often attacked by more than one herbivore species. We investigated the olfactory response of a generalist predators Macrolophus caliginosus to pepper infested with two-spotted spider mites, Tetranychus urticae, or green peach aphid, Myzus persicae, vs. plants infested with both herbivore species in a Y-tube olfactometer set up. In addition, the constituents of volatile blends from plants exposed to multiple or single herbivory were identified by gas chromatography-mass spectrometry (GC-MS). The mirid bugs showed a stronger response to volatiles emitted from plants simultaneously infested with spider mites and aphids than to those emitted from plants infested by just one herbivore, irrespective of the species. Combined with results from previous studies under similar conditions we infer that this was a reaction to herbivore induced plant volatiles. The GC-MS analysis showed that single herbivory induced the release of 22 additional compounds as compared with the volatiles emitted from clean plants. Quantitative analyses revealed that the amount of volatile blends emitted from pepper infested by both herbivores was significantly higher than that from pepper infested by a single herbivore. Moreover, two unique substances were tentatively identified (with a probability of 94% and 91%, respectively) in volatiles emitted by multiple herbivory damaged plants: a-zingiberene and dodecyl acetate.
