“…This region corresponds to the expansion area of T. pityocampa (Robinet et al, 2007) where driving factors of population dynamics can be different than those operating in the core area. For example the natural enemies of the pine processionary moth may have not yet followed their prey in the new colonized range (Auger-Rozenberg et al, 2015). The spectral analysis also failed to detect regular cycles in about 30% of the clusters of plots.…”

“…Besides the two species previously noted as preying upon it, namely R. euryale and M. schreibersii (Arrizabalaga-Escudero, 2016; Aizpurua et al, 2018; Galan et al, 2018) our study has unfolded predation by another five. Remarkably, we found that T. pityocampa is also eaten by R. ferrumequinum , a horseshoe bat previously discarded as a potential consumer of this pest because it has seldom been reported using pine stands as hunting grounds (Auger-Rozenberg et al, 2015). P. austriacus and B. barbastellus had been already appointed as potential predators of T. pityocampa (Charbonnier, Barbaro & Theillout, 2014; Auger-Rozenberg et al, 2015) whereas T. teniotis and N. lasiopterus have never been referred to.…”

The low dependency of H. savii on moths (Beck, 1995; Horáček & Benda, 2004; Whitaker & Karataş, 2009) may explain the differences observed between this and other edge space foragers.…”

“…T. pityocampa also have a diverse array of natural predators, however, many of them are either occasional or incidental (Hódar, Torres-Muros & Senhadji, 2013) and mortality caused by most does not apparently affect population dynamics (Battisti et al, 2015). Bats and nightjars ( Caprimulgus spp) are the main vertebrate consumers of the adult moth (Auger-Rozenberg et al, 2015), but because bats are overwhelmingly in higher numbers than nightjars, the former are expected to pose the main predatory threat to the moth.…”

Bats from different foraging guilds prey upon the pine processionary moth

Outbreaks of the processionary moth Thaumetopoea pityocampa (Denis & Schiffermüller, 1775), a forest pest from the Palearctic, are thought to induce a behavioral response of bats, but up to now the moth has been seldom identified as bats’ prey. Studies on bat diets suggest moths with cyclical outbreaks attract a wide array of bat species from different foraging guilds. We test whether bats feed upon T. pityocampa in the Iberian Peninsula irrespective of the predator’s ecological and morphological features. We found that seven out of ten bat species belonging to different foraging guilds contained T. pityocampa DNA in their faeces and no difference was found in the foraging frequency among foraging guilds. A different size of the typical prey or the lack of fondness for moths can explain the absence of the pest in some bat species. Moreover, the intraspecific foraging frequency of T. pityocampa also changed with the sampling site likely representing differential availability of the moth. Lack of information on flight and dispersal behavior or the tympanate nature of the adult moth complicates understanding how different foraging guilds of bats prey upon the same prey. Our data suggests that T. pityocampa is a remarkable food source for many thousands of individual bats in the study area and we anticipate that more bats besides the species studied here are consuming this moth.

“…Moreover, insecticide applications in the anthropized sites may be ineffective, as some parts of the plants remain untreated and spraying in inhabited areas often triggers complaints from residents. Biological control has to be stringently applied to achieve a satisfactory level of management [8,9,10,11].…”

Recent Advances in Management by Pheromones of Thaumetopoea Moths in Urban Parks and Woodland Recreational Areas

Caterpillars of the pine processionary moths, Thaumetopoea complex, cause serious defoliation to Cedrus, Pinus, and Pseudotsuga trees. Thaumetopoea caterpillars also have fine hairs on their abdominal tergites that contain a protein that can severely irritate and cause dermatitis in humans and domestic animals. The control of the T. pityocampa pine processionary moth has become necessary in many European countries because of the sanitary risks that are related to larval urtication and the defoliation threat to pine forests and plantations. New research activities have been aimed at the development of eco-friendly, innovative technologies for Integrated Pest Management (IPM) of these moths, particularly in urban parks and woodland recreational areas. This paper describes the recent advances in the use of pheromones in monitoring, mass trapping, and mating disruption related to management of processionary moths T. hellenica and T. pityocampa. According to the results, the use of pheromones may provide a practical alternative to insecticide sprays, as they can be safe and simple as compared to other control methods.
