“…Two main hypotheses have been postulated to explain such decline: a constraining climate factor not considered in the current formulation of the model; and the effect of a new biotic agent, the exotic seed bug Leptoglossus occidentalis (Heid.) (Bracalini et al, 2013;Lesieur et al, 2014). Seed predation by this insect has been described as a cause of the abortion of unripe conelets, as well as for provoking a significant reduction of the seed yields in mature cones (Mutke et al, 2014;.…”

Aim of the study: To present a new spatiotemporal model for Pinus pinea L. annual cone production with validity for Spanish Northen Plateau and Central Range regions. The new model aims to deal with detected deficiencies in previous models: temporal shortage, overestimation of cone production on recent years, incompatibility with data from National Forest Inventory, difficulty for upscaling and ignorance of the inhibitory process due to resource depletion.Area of study: Spanish Northern Plateau and Central Range regions, covering an area where stone pine occupies more than 90,000 ha.Material and methods: Fitting data set include 190 plots and more than 1000 trees were cone production has been annually collected from 1996 to 2014. Models were fitted independently for each region, by means of zero-inflated log normal techniques. Validation of the models was carried out over the annual series of cone production at forest scale.Results: The spatial and temporal factors influencing cone production are similar in both regions, thus the main regional differences in cone yield are related with differences in the phenological timing, the intensity of the influent factors and forest intrinsic conditions. A significant inhibition of floral induction by resource depletion was detected and included into the model. Upscaling the model results in accurate prediction at forest scale.Research highlights:[1] The new model for annual cone production surpass the detected deficiencies of previous models, accurately predicting recent decay in cone production; [2] Regional differences in cone production are due to phenological and seasonal climatic differences rather than to between provenances genetic differences.

“…The results of a research conducted by Bracalini et al [68] at Maremma regional park in Italy also suggested that the low cone production and high number of damaged seeds agree with an overall decline of stone pine nut production in Tuscany (Italy). The authors claim that the findings have been confirmed by the local nut producing companies [68].…”

“…There are many cone and seed insects of pines mentioned in the literature. For example, Dioryctria mendacella Staudinger, Ernobius parens Mulsant and Rey, Ernobius impressithorax Pic, Pissodes validirostris Sahlberg, and L. occidentalis [64][65][66][67][68]. However, L. occidentalis is one of the most extensively studied insect vectors on pine nuts.…”

Pine nuts are non-wood forest products (NWFP) with a constantly growing market notwithstanding a series of phytosanitary issues and related trade problems. The aim of this paper is to review the literature on the relationship between phytosanitary problems and trade development. Production and trade of pine nuts in Mediterranean Europe have been negatively affected by the spreading of Diplodia sapinea (a fungus) associated with an adventive insect Leptoglossus occidentalis (fungal vector), with impacts on forest management, production and profitability and thus in value chain organization. Reduced availability of domestic production in markets with a growing demand has stimulated the import of pine nuts. China has become a leading exporter of pine nuts, but its export is affected by a symptom caused by the nuts of some pine species: 'pine nut syndrome' (PNS). Most of the studies mentioned in the literature review concern PNS occurrence associated with the nuts of Pinus armandii. We highlight the need for a comprehensive and interdisciplinary approach to the analysis of the pine nuts value chain organization, where research on food properties and clinical toxicology may be connected to breeding and forest management, forest pathology and entomology, and trade development.

“…L. occidentalis L. feeds on the green tissues and cones of conifer hosts; the damage is economically disastrous when it attacks the cones ( Figure 4) and seeds of the stone pine [95], directly hurting the nut industry. Furthermore, stone pines typify the landscape in the coastal areas of many central and southern Italian regions; their waning could cause economic losses in the tourism sector.…”

Abstract:The present-day phytosanitary disasters caused by biological invasions are afflicting urban and peri-urban forest stands worldwide, as well as the varied services they normally provide. In Europe, we are witnessing an alarming situation due to an increasing introduction of infectious diseases and pests. The authors present an up-to-date list of alien microbial pathogens and insect pests affecting urban greening that have been accidentally imported in Italy or that are likely to be introduced. Information about the biology, epidemiology, ethology, and control of these invasive organisms is provided. For each species, the current geographical distribution, including newly-colonized areas, is also given, as well as the chronological progression of its occurrence. Particular detail is used for describing symptoms-the key diagnostic elements for appropriate and timely phytosanitary management. This paper will benefit urban forest management, which is a crucial factor in maintaining the social and ecological viability of urban green spaces, as well as ecosystem services. The importance of engaging citizens in community-based monitoring of urban greenspaces for tracking the location, abundance, and pathways of invasive pathogens and pests will also be touched upon.
