“…For example, the volatile profiles of Pinus caribaea var. bahamensis were reported to be valid indicators of susceptibility towards PTS and predictors of environmental stresses (Green et al 2015(Green et al , 2017. The same approach should be considered to characterize the interactions established between PTS and P. pinea in Italy.…”

Invasive pests are considered a major threat to biodiversity, conservation and agriculture. The Italian peninsula is a major site of intensive commercial exchange and transport of plants and goods, being consequently one of the European countries most invaded by alien insects. Hemiptera Coccomorpha are the largest group of non-native species recorded in Europe. For example, in the last 70 years more than 50 scale insect species have been accidentally introduced into Italy, 50% of which are now well established. This study was conducted to investigate the biology and the damage of the non-native pine tortoise scale Toumeyella parvicornis Cockerell (Hemiptera: Coccidae) accidentally introduced a few years ago into southern Italy. T. parvicornis is multivoltine in the invaded territories, being able to complete at least three generations per year, overwintering in the adult female stage. Oviposition periods during 2015-2017 surveys occurred from late April to end of May, from July to first half of August, and from mid-September to November. Fecundity was positively correlated to body size of gravid females and varied among the generations. Investigations on natural control by autochthonous species showed a seasonal activity of Metaphycus flavus (Hymenoptera: Encyrtidae), parasitizing mainly immature male individuals. The morpho-molecular approach confirms the hypothesis of an ongoing shift of parasitoid populations from other indigenous soft scales to the invasive one. Unfortunately, the low level of natural control was ineffective in hampering the spread of T. parvicornis, and preventing the dieback of local pine species, Pinus pinea, as observed in all invaded areas.

“…4), the CPRP team developed a trail (∼1 m wide) partially based on a historic path (Manco et al., 2016) to access patches of the remaining forest. This enabled the development of three Permanent Monitoring Plots in 2010 (Earle-Mundil, 2010) within the North Caicos CCA, seed collecting from the few trees that survived the fire, seedling rescue from areas prone to flooding, and comparative research across the three CCAs as reported in Green et al. (2017) and Sanchez et al.…”

“…In response to the discouraging challenges TCI's wild Caicos pine populations are facing, the CPRP team of local and international scientists and conservationists have developed a restoration strategy to rescue this taxon from local extinction (Hamilton et al., 2016). The strategy is based on tested horticultural protocols for growing Caicos pines locally (Sanchez et al., 2016b), data from permanent monitoring plots established in the pine yards (Earle-Mundil, 2010) and scientific research on pine population genetics, mycology, restoration ecology, chemical volatiles and seed biology (Green et al., 2017, Sanchez et al., 2016a). Concomitantly, to ensure that sufficient genetic diversity was captured before all mature trees died in the wild, saplings were rescued from badly infested areas, seeds were collected for propagation and gene banking, and saplings were locally propagated for re-introduction.…”

The severe and rapid attack on the Caicos pine Pinus caribaea var. bahamensis (Pinaceae) by the non-native invasive pine tortoise scale, Toumeyella parvicornis , has resulted in the death of most of the trees in the Turks and Caicos Islands (TCI) in just over a decade. Local and international conservation efforts have enabled the necessary multi-disciplinary research, data gathering, and monitoring to develop and implement a restoration strategy for this endemic tree from the Bahaman archipelago. The native plant nursery established on North Caicos and horticultural expertise acquired throughout the years were crucial to the successful rescue of Caicos pine saplings from the wild populations and cultivation of new saplings grown from locally sourced seeds. These saplings have been used to establish six Restoration Trial Plots on Pine Cay and a seed orchard on North Caicos in TCI. Core Conservation Areas (CCAs) for the Caicos pine forests have been identified and mapped. To date, forest within the Pine Cay CCA has been supplemented by planting more than 450 pine trees, which have survived at a high (>80%) rate.
