To prevent or manage invasions <strong>of</strong> alien species, it is vital to study<br />

their invasion potential before they colonize new areas. We<br />

assessed the potential <strong>of</strong> a well-known invader, the Colorado<br />

potato beetle (Leptinotarsa decemlineata), to expand north <strong>of</strong> its<br />

current range in Europe by studying genetic variability in life history<br />

traits from four geographically distinct populations (Russia, Estonia,<br />

Poland and Italy). We further assessed the cold tolerance during<br />

development and whether mild stress (pesticide) confers cost in<br />

terms <strong>of</strong> metabolic rate and fat content. Our results show that<br />

European L. decemlineata still exhibit adaptive genetic variation in<br />

life-history traits, indicating that there is potential for evolution in<br />

these traits. In particular the northern population (St. Petersburg,<br />

Russia) <strong>of</strong> L..decemlineata developed significantly faster than the<br />

central one (Poland), indicating adaptation to a short growing<br />

season. Beetles were very cold tolerant as exposing larvae to<br />

subzero temperature (simulating night frosts) did not incur mortality.<br />

We found also that pesticide selection (i.e. parents exposed to<br />

pesticides) can cause significant costs in their <strong>of</strong>fspring (smaller<br />

size, higher metabolic rate), which impairs overwintering success<br />

and thereby may retard their invasion potential and colonization<br />

success. This study demonstrates the importance <strong>of</strong> considering<br />

both ecological and evolutionary aspects when assessing invasion<br />

risk.<br />

The dynamics <strong>of</strong> populations and damage on three industrial vines<br />

newly introduced in Algeria has been studied in a vineyard to the<br />

west <strong>of</strong> the plain <strong>of</strong> the Mitidja by numbering <strong>of</strong> larvae on whole<br />

plants and adults captured by yellow chromoactive traps during<br />

two consecutive years 2005 to 2006. The follow-up <strong>of</strong> populations<br />

showed the succession <strong>of</strong> four generations and those from the<br />

month <strong>of</strong> April until the month <strong>of</strong> August for the two years <strong>of</strong> the<br />

follow-up. The exam <strong>of</strong> infestations showed that the Merlot vine<br />

accuses big preferences in relation to cabernet sauvignon and the<br />

Syrah, indeed the number <strong>of</strong> green leafhopper observed on these<br />

last vines in 2nd and 3rd generations passes the recommended<br />

percentage extensively. The leaf damage was observed in all<br />

variety, so Merlot variety accused the most important damage,<br />

80% <strong>of</strong> their leaf were attacked, 45% about Cabernet-Sauvignon<br />

and 25% for Syrah variety.<br />

The scales on vines were seen from nearly a century as secondary<br />

pests. Recent experiments have shown their involvement in the<br />

transfer and the spread <strong>of</strong> the disease <strong>of</strong> winding vines, which may<br />

affect somewhat taking into account their control. Under a<br />

monitoring pest <strong>of</strong> vineyard in Algeria, mealybug proved as an<br />

important major economic pest in Northen Vineyard <strong>of</strong> Algeria. In<br />

this study we describe and evaluate, infestations, estimate the<br />

damage and understand the sensitivity <strong>of</strong> type <strong>of</strong> wines in Mitidja<br />

areas Northern <strong>of</strong> Algeria. The monitoring was conducted during<br />

2007 season, during spring and summer, the results have shown<br />

differences between grapes and appellations, rates vary<br />

infestations, damage estimated seem to be important mainly for<br />

the some variety Mitidja.<br />

Reintroduction <strong>of</strong> Chinese water deer(Hydropotes inermis)<br />

to Shanghai, China<br />

Chinese water deer ( Hydropotes inermis ) is classified as the<br />

second class <strong>of</strong> protected animals in China, and ranked as LR/nt in<br />

IUCN red data book. The distribution and population <strong>of</strong> the water<br />

deer in China were declined rapidly, the species suffered habited<br />

lost. Based on partly survey, the totally number <strong>of</strong> the Chinese<br />

water deer was estimated not more than 10,000 in the field. It is<br />

necessary to making strategy on conservation and management to<br />

recovery the species. Assessing the feasibility for reintroduction <strong>of</strong><br />

the Chinese water deer based on textual research <strong>of</strong> the deer<br />

populations in the history, survival condition, investigation <strong>of</strong> public<br />

attitude and local condition. The water deer only disappeared in<br />

Shanghai only about 100 years, and most surveyed local people<br />

would like to invest to reintroduction <strong>of</strong> the water deer. The project<br />

selected a plot in Shanghai to the reintroduction and aims to<br />

recovery Chinese water deer in Shanghai. A group <strong>of</strong> Chinese<br />

water deer have been released into a Park on the round-the-city<br />

greenbelt area between rural and urban <strong>of</strong> Shanghai in 2007. If the<br />

water deer can inhabit Shanghai and no incline to invasive local<br />

ecology by monitoring <strong>of</strong> this population, we will plan to release the<br />

deer to open areas around the city.<br />

A pr<strong>of</strong>ile <strong>of</strong> bird invasions – how are they related to European<br />

politics?<br />

We questioned whether European politics in the 20 th century were<br />

responsible for less introductions <strong>of</strong> birds in Eastern Europe than<br />

in Western Europe. We focused on the consequences <strong>of</strong> the socalled<br />

Cold War (1949-1991) that split Europe into two political and<br />

economic blocs. During this period, every aspect <strong>of</strong> trade and<br />

abilities <strong>of</strong> humans to travel have been affected, isolating the<br />

Eastern Europe from the rest <strong>of</strong> the world. To test embargo effects<br />

on bird introductions in Eastern Europe, we assessed variations <strong>of</strong><br />

introduction efforts between the Eastern and the Western blocs,<br />

before, during and after the Cold War. We expected that the<br />

embargo has drastically disrupted introductions <strong>of</strong> birds imported<br />

from other continents.<br />

We used a very recent dataset on bird invasions we generated as<br />

part <strong>of</strong> DAISIE 1 consortium. Introduction histories are presented in<br />

the context <strong>of</strong> trade and people movement regulation policies and<br />

impacts <strong>of</strong> the Cold War were tested using an experimental design<br />

<strong>of</strong> analysis. Our results pointed out the effect <strong>of</strong> the embargo on<br />

the number <strong>of</strong> birds transported and released in Eastern Europe<br />

during the Cold War. Further, we showed the importance <strong>of</strong><br />

multilateral agreements involving countries <strong>of</strong> a same bloc on<br />

pattern <strong>of</strong> introductions.<br />

This study suggests that politics can affect human activities and<br />

subsequent introductions <strong>of</strong> birds at the scale <strong>of</strong> Europe. Any large<br />

scale study should consider economic and political history as a key<br />

factor to understand bird invasion patterns.<br />
