Catalonia recently hosted a national simulation exercise in Tarragona to strengthen preparedness against the potential detection of the Popillia japonica, an invasive Japanese beetle. This coleopteran poses a significant threat to agricultural crops, green spaces, and natural ecosystems.
The drill, organised by the Department of Agriculture, Livestock, Fisheries and Food in coordination with the Ministry of Agriculture, Fisheries and Food (MAPA), brought together nearly 70 professionals from various autonomous communities across Spain. The main goal was to test surveillance, notification, and diagnosis protocols for an eventual appearance of the beetle. It also aimed to improve coordination between administrations and on-the-ground intervention teams.
Why the Japanese Beetle is a Concern
This invasive beetle is particularly worrying due to its rapid expansion capabilities and the risk of dispersal through the transport of goods, vehicles, or plant material. Its presence has already been detected in various parts of Europe, leading to reinforced phytosanitary surveillance systems. According to officials, the beetle is already a serious problem in North America and parts of Europe.
New invasive species threats arrive at a time of growing concern over the spread of the Asian hornet, Vespa velutina, which has expanded its presence in Catalonia in recent years. This species primarily affects bees and biodiversity, and also causes public alarm due to nests found in urban and natural areas.
Strengthening Regional Defence
The increase in invasive pests and harmful organisms has forced administrations to reinforce prevention and rapid response systems. This is especially true in strategic territories like Catalonia, which features international ports, airports, and high mobility of goods and people.
During the simulation, complementary technical activities and exchange sessions were organised among specialists from different regions. These sessions allowed participants to share protocols and experiences. The Generalitat highlighted that such exercises help identify areas for improvement and strengthen operational capacity against threats that could have a strong agricultural, environmental, and economic impact.
