The knowledge of the endemic drosophilid assemblage is a useful reference to study population dynamics when new species are introduced in a geographical area. The introduction of invasive species can change the structure of the drosophilid community; hence, the distribution data for endemic...

This article provides a comparison of the vascular alien flora of Sardinia (Italy) and that of Corsica (France), both territories belonging to the Western Mediterranean biogeographic subregion. The study has recorded 598 (90 doubtful) alien taxa in Sardinia (18% of the total flora) while 553 (87...

Climate variability may enhance the establishment of pests into areas which had been previously unfavourable for survival and establishment because of unsuitable climatic conditions. Within the wider Caribbean geographic area, there have been several introductions of invasive pest species over the...

This proceedings contains papers focusing on the current situation of invasive alien species (IAS; including insect pests, weeds and aquatic organisms) in natural and agricultural areas in the region. These papers discusses the different aspects of IAS, presenting the latest situation that has been ...

Information about the geographic distribution of agricultural pests is the basis for all pest-related agricultural and environmental protection policies. However, often the pest's records are incomplete and uncertain. Even with limitations, the pest records are needed for any country to organize a...

The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae), is a pest from Southeast Asia accidentally introduced into North Africa and Europe two decades ago. In Sicily, RPW was recorded for the first time in 2005, then, in few years, it established becoming the most...

In Slovenia, pines (Pinus spp.) are frequently damaged by numerous autochthonous diseases and pests, but introductions of alien harmful organisms represent even higher dangers for pine trees. Estimated loss as a consequence of these introductions will be a sum of direct losses connected to the...

The two congeneric sea rockets (Cakile maritima and Cakile edentula) have invaded coastal sand dunes in Australia. C. edentula was the first species to arrive; however, it almost disappeared and was replaced by the later introduced C. maritima. A higher level of variation (genetic and phenotypic)...

Plant invasions continue to extract a huge environmental and economic toll worldwide. Consequently, sustaining the control of these pests as well as limiting the spread of potentially invasive plants would seem topics of accepted public policy. They are however anything but permanent, the...
