This Thursday, September 22, CTT will present a philatelic broadcast on the International Year of Plant Health, recognized by the United Nations as being of great importance for life on Earth.
In this issue, four species are represented: the phylloxera, the pine longicorn, the fruit fly and the palm beetle.
Phylloxera is an insect originating in North America, having first appeared in Europe in 1863, in France. Portugal was very affected, with the first official record dated 1871 in the Douro region, where many vineyards were completely destroyed and transformed into extensive areas of the Douro landscape, causing the ruin and depopulation of the regions most affected. It was precisely with phylloxera that the concept of plant protection was born globally and, consequently, in 1881, a Convention was signed in Bern, between 5 countries (Germany, Austria-Hungary, France, Portugal and Switzerland).
The Pine Wood Nematode (PWN) is considered as one of the organisms that has the greatest destructive potential for the coniferous forest. This microscopic worm is transmitted to trees by an insect - in Portugal, it is the Longicorn-of-pine. In Europe, the nematode was first identified in mainland Portugal in 1999 and, more recently, on the island of Madeira and Spain. Currently, PWN is one of the main phytosanitary problems in our pine forest.
The fruit fly is a pest that attacks various crops and also spontaneous plants, depositing their eggs in the fruits. Its larvae cause significant damage and make the affected fruit unavailable for sale. As it is a very dispersed insect in our territory, it is also one of the main restrictions on the export of national fruit to third countries. Its effective control is not only crucial for safeguarding the sustainability of national production, given that it affects most of the fruits, but it is also essential for international phytosanitary agreements to be made to export our fruits.
Finally, the Escaravelho-da-paleira attacks several species of palm trees, causing damage that, without proper treatment, can lead to the death of these plants. In Portugal, this insect was first detected in 2007, in the Algarve, and is currently dispersed over a large part of the national territory, having led to the death of thousands of palm trees throughout the country, altering the landscape of many places .
This philatelic issue consists of four stamps, each with a circulation of 100,000 copies each and face values of € 0.53, € 0.86, € 0.91 and € 2.00. The design was in charge of Francisco Galamba of CTT and the illustrations are by Nuno Farinha.
The first day's obliterations will be made at Restauradores stores in Lisbon, Municipality II in Porto, Zarco in Funchal and Antero de Quental in Ponta Delgada.
