“…Therefore, in terms of metapopulation dynamics the transition from empty to occupied patches can be considered as the immediate consequence of patch colonization rather than within-patch processes. The documented contribution of the movement to the local dynamics in many forest Lepidoptera species like PPM (Masutti and Battisti, 1990) further justifies the role of connectivity and of the colonization process in metapopulation dynamics.…”

“…and Schiff), PPM) populations dynamics in fragmented forest stands of the National Park of Aspromonte, Calabria, Italy. Infestations by PPM cause damage to pine trees that may result in yield loss, negatively affect the value of forests for recreational purposes and diminish the aesthetic value of individual trees in urban environments (Masutti and Battisti, 1990). Pest status is further increased by the production of setae by larvae, often causing serious allergic reactions in humans and various animals (Lamy, 1990).…”

a b s t r a c tForecasting pest population abundance is a time and resource consuming task, and in particular for areawide pest management is complicated by demographic and environmental stochasticity. These factors make difficult the development of quantitative tools to design and evaluate different management strategies performances by taking into account various form of variability and uncertainty. Pest management could benefit from methods supporting decision making based on models ease of development under scarce data and high uncertainty. Host plants for many agricultural and forest pests are often patchily distributed, therefore population dynamics can be suitably described in terms of metapopulations. Despite the fact that metapopulation models were originally proposed for pests, they remain a widely used tool in conservation biology but receive little attention in large scale pest management.The aim of this paper is to propose a framework allowing the ranking of the efficacy of area-wide pest control strategies, taking into account population spatial distribution in discrete patches. The Kullback-Leibler divergence, well known in Information Theory, Probability and Statistics, is used to measure how far the state of the metapopulation as predicted by a spatially explicit metapopulation model is from a suitable reference state.The method is applied to compare the efficacy of different types of predefined control strategies of the Pine processionary moth (Traumatocampa pityocampa (Den. and Schiff)). The analysis of a dataset on metapopulation dynamics of this moth from a fragmented Mediterranean pine forest allows to derive some rules of thumb for the rational allocation of control effort, in terms of spatial and temporal distribution of the interventions.

Abstract:The Pine Processionary moth in the pinewoods of Calabrian Apennines, Italy. The results of a study carried out on the Pine Processionary moth [Traumatocampa (=Thaumetopoea) pityocampa (Denis & Schiffermüller)] in Calabria (Italy) during 1997-98 are reported. The preliminary aim of this investigation was to assess the presence of the lepidopteran in the main pinewoods of the Calabrian Apennine ridge. The research started with a census, conducted in 1997, of the areas where the Processionary moth was present; in the second year (1998) male flight dynamics were monitored using pheromone traps in 26 selected sites. Besides, during the first year the infestation levels were measured, recording the percentage of infested plants as well as the number of nests on 10 infested trees randomly chosen. The correlation coefficient of the above-mentioned parameters was measured in order to be able to optimize the monitoring system. The data collected confirmed that the Pine Processionary caterpillars adapt their own biology and ethology to the different altitudes and to the various climatic conditions of the Calabrian pinewoods. Pure pinewoods were more infested than the mixed ones, besides artificial woods were more susceptible to the attacks of the moth than the natural ones. The parameters that were measured (% of infested plants and number of winter nests per plant) were positively and significantly correlated. Male captures were higher at elevations ranging from 0 to 400 m and peaked in August up to 800 m and at the beginning of July between 800 and 1400 m. Statistical analysis showed that the number of nests per plant is not significantly related to the number of male captures during the following season. IntroduzioneIl lepidottero notodontide Traumatocampa (=Thau-metopoea) pityocampa (Denis & Schiffermüller) ( fig. 1) comunemente noto come "Processionaria dei pini" è sicuramente il fitofago chiave nella gestione delle pinete vegetanti nell'areale Mediterraneo.E' un defogliatore tipicamente legato a diverse specie del genere Pinus, e in presenza di formazioni miste dello stesso, l'attività defogliatrice risulta più marcata (Tiberi 1983). Ospiti occasionali del lepidottero possono essere: Cedrus spp., Picea abies L. e Pseudotsuga menziesii (Mirbel) (Battisti 1986). Nelle regioni meridionali italiane, i maggiori danni, in rapporto ai luoghi e alle condizioni di vegetazione, sono segnalati su Pinus pinaster Aiton nei popolamenti naturali dell'isola di Pantelleria e nelle formazioni degradate lungo il litorale ionico, nonché in comprensori dell'Etna a quota 2000 m su Pinus laricio Poiret, dove la specie è stata utilizzata per i rimboschimenti .

“…The pine processionary moth (Lepidoptera, Notodontidae), hereafter PPM, is an economically important pine pest in the Mediterranean forests (Masutti and Battisti, 1990), as its larvae feed on needles of pines, and its urticating larval setae cause severe allergy, especially in mammals (Vega et al, 1997;Rodríguez-Mahillo et al, 2012). PPM larval development generally occurs through the winter.…”

The pine processionary moths Thaumetopoea pityocampa and T. wilkinsoni are among the most important Mediterranean pine defoliators. Although recent studies suggest that the two species may coexist in Turkey, the relevant literature lacks precise information on the occurrence and exact distribution of the two species in this country. In particular, whether the two sister taxa form a contact zone is still unknown. In this study, we aimed to reveal the limits of the ranges of the two species in Turkey by using nuclear (ITS-1, photolyase) and mitochondrial markers (COI). Multilocus molecular characterization of the two species showed for the first time that the two species co-occur in some of the sampling sites. In addition, we determined clear signatures of mitochondrial introgression between the two species, and therefore the existence of a possible hybrid zone within Turkey. These results bring up interesting questions relating to the evolution of the identified hybrid zone.
