“…The observation that significantly more male moths were captured in pheromone traps when they were positioned in Q. robur suggested that the moths were orientating specifically to traps in this tree species for a reason, and hence that they may have been influenced by the volatile components of the foliage. Numerous studies have demonstrated that plant volatile organic compounds (VOCs), particularly green leaf volatiles, can be highly influential in attracting and repelling insects (Reddy & Guerrero, ; Bruce & Pickett, ; Xu & Turlings, ). Since OPM is a monophagous insect feeding only on Quercus spp., adult moths need to be able to orientate to specific host plants to maximize their reproductive success.…”

“…Because woodlands and amenity areas are commonly planted with a wide range of tree species, it is particularly important to establish whether the positioning of pheromone traps for OPM needs to be in oak trees or whether it can be just as effective to place pheromone traps in other tree species. There are now many examples demonstrating that plant volatiles (semiochemicals) can synergistically enhance the response or modify the behaviour of a male insect to the female sex pheromone (Landolt & Phillips, ; Reddy & Guerrero, ; Bruce & Pickett, ; Xu & Turlings, ). Although most studies describe the synergistic improvements that plant volatiles have on male insects responding to the female sex pheromones, there are also examples where plant volatiles can inhibit or repel insects (Reddy & Guerrero, ).…”

1 Many factors influence the efficiency of insect pheromone trapping systems. In particular, captures of male oak processionary moth (OPM) Thaumetopoea processionea in pheromone traps can be highly variable, hence, two trials were conducted to determine whether the tree species in which traps are positioned or edge effects are influential factors in OPM pheromone trapping. 2 In a 'host plant trial', pheromone traps that were positioned in the canopy of pedunculate oak (Quercus robur) trees captured significantly more male OPM than traps positioned in any of the other six tree species (including other species of oak) used in the trial over two successive years. 3 In an 'edge effects trial', pheromone traps positioned on the edges of oak woodland blocks captured more moths than traps positioned within the oak woodland itself. 4 Although wind direction influenced the numbers of moths that were captured in pheromone traps on woodland edges, with more moths captured in traps positioned on sheltered north-facing edges, the differences in trap catches between north, south, east and west edges were not significant. 5 The results from the present study indicate that a greater emphasis should be taken to deploy pheromone traps for oak processionary moth in the canopies of pedunculate oak trees with an open, sunnier disposition rather than within the interior of the forest or woodland, thereby maximizing their efficiency.

“…We found that the relatively low concentration of β-caryophyllene can attract gravid females, while a higher level of β-caryophyllene deterred oviposition in the fruits, showing that the olfactory response of gravid females of B. dorsalis to β-caryophyllene is dose-dependent. The volatiles released by host plants provide essential information for phytophagous insects to identify and locate their hosts 46–48 . β-caryophyllene is a typical terpenoid emitted by many kinds of plants, and β-caryophyllene plays an essential role in attracting or avoiding phytophagous insects.…”

“…Volatile organic compounds (VOCs) are particularly effective in specialist herbivore species foraging in a highly complex environment mixing very different stimuli (Schröder & Hilker, 2008). Plant VOCs have also been shown to act synergistically with sex pheromones to enhance male moth attraction to female pheromones (Landolt & Phillips, 1997;Reddy & Guerrero, 2004;Bruce & Pickett, 2011;Xu & Turlings, 2018). Thus, we can speculate that Q. petraea released a specific blend of VOCs that improved the response of male OPMs to pheromone lures.…”

Pure forests are often seen as being more prone to damage by specialist pest insects than mixed forests, and particularly mixed forests associating host and nonhost species. We addressed the effect of tree diversity on oak colonization and defoliation by a major specialist pest, the oak processionary moth (OPM) We quantified the number of male OPM moths captured and larval defoliation in pure stands of two oak host species (Quercus robur and Quercus petraea) and in mixed stands associating the two oak species or each oak species with another nonhost broadleaved species. We conducted two complementary studies to test the effect of host species and stand composition: (i) we used pheromone trapping to compare the number of males OPM captured throughout the distribution of oak hosts in France and (ii) we noted the presence of OPM nests and estimated defoliation in mature forests of north‐eastern France. Oak species and stand composition significantly influenced the number of male OPM captured and defoliation by OPM larvae. Quercus petraea was consistently more attractive to and more defoliated by OPM than Q. robur. Both oak trees were attacked more in pure stands than in mixed stands, in particular mixed stands associating oaks with another (nonhost) broadleaved species. The results of the present study support the view that mixed forests are more resistant to specialist pest insects than pure stands, and also indicate that this trend depends on forest composition. Our study provides new insights into OPM ecology and has potential implications for forest management, including the management of urban forests where OPM causes serious human health issues.
