Tunisian Journal of Plant Protection Vol. 11, No. 2, 2016 Guest Editorial Reflection on forest insect pests in the Mediterranean region, with particular attention to Tunisia The forest area in Mediterranean health problems, including those countries was over 85 million ha, associated with insect pests and diseases. representing 2% of the world’s forest A total of 89 insect pests with area. The Mediterranean vegetation major outbreaks were reported from the support 20% of the plant species on Mediterranean countries (FAO, 2013). Earth, where there are more than 25 000 Over the 27 insect pests reported as the plant species and more than half are most serious ones, 13 were coleopterans endemic. Many hot spots are located (beetles), 9 were lepidopterans there, giving to the Mediterranean (butterflies and moths), 4 were ecosystems a high biological value. The hymenopterans (sawflies), and one was a climate is typically warm temperate, with hemipteran (aphid). a dry summer season usually not Insect pests indigenous to the exceeding 4 months but giving it a certain Mediterranean region cause considerable severity. Everywhere however, climate damage. Bark beetles count among the change allows worrying about dramatic most dangerous insects that attack pine problems regarding tree health, as well forests to which they can cause severe as risk of extension of Mediterranean damage, such as Tomicus destruens and pests outside of their native areas. Orthotomicus erosus which is a carrier of The Mediterranean vegetation is pathogenic fungi and is known to carry dominated by evergreen shrubs and Sphaeropsis sapinea, which causes sclerophyllous trees adapted to the mortality in many Pinus species. distinctive climatic regime of summer Defoliators such as the gypsy moth drought and cool moist winters with only (Lymantria dispar) and Pine sporadic frost. In addition to the Processionary Moth ‘PPM’ woodland, we distinguish two main types (Thaumetopoea pityocampa) are also a of degraded forest, the maquis (dense regional problem. L. dispar is a shrub formations) and garrigue (more significant pest because the caterpillars open and aromatic shrubs). The most have various appetites for more than 300 forest species are: Quercussuber (cork species of trees and shrubs. The oak), Quercus ilex (holm oak), Cedrus caterpillars defoliate trees, leaving trees atlantica (Atlas cedar), Pinus halepensis vulnerable to diseases and can eventually (Aleppo pine), Pinus pinea (stone pine), kill the tree. In Tunisia, currently, this Pinus pinaster (Maritime pine). pest is in a latency phase (low level and The Mediterranean forest is absence of defoliation). However, since threatened by abiotic factors (such as air 1995 the PPM’s range has been pollution, storms, drought and fire) and expanding constantly, in both latitude and other biotic factors (such as woody altitude. Moreover, in some areas, invasive species, wildlife browsing and outbreaks are becoming more severe, as grazing). They also have many forest well as repeating over time. The PPM is a major pest in the Mediterranean basin Tunisian Journal of Plant Protection Vol. 11, No. 2, 2016 due to their larvae, which voraciously destroying many hectares of planted feed on pine needles and have urticating areas. P. semipunctata was established in hairs.
