The number of flying insects in Germany has been dropping at an "alarming" rate that could signal serious trouble for ecosystems and food chains in the future, scientists say.

According to a study published Wednesday in the journal PLOS ONE, researchers using funnel-shaped traps at 63 sites across western Germany recorded a 76 percent decline in bug volume from 1989 to 2016. The midsummer loss during the 27-year-period was as high as 82 percent.
"The widespread insect biomass decline is alarming, ever more so as all traps were placed in protected areas that are meant to preserve ecosystem functions and biodiversity," the authors said.
The drop in airborne insects over Germany was higher than the global estimated insect decline of 58 percent between 1970 and 2012.
The researchers, led by Caspar Hallmann of Radboud University in Nijmegen, Netherlands, said it was unclear why the numbers in Germany have declined so sharply, but concluded that neither landscape nor climate change are likely to be the cause.

Instead, they speculated that intensive agriculture and pesticide use may be to blame. The authors called for further research into the possible reasons for the decline, noting that flying insects play an important role in pollinating plants and are a source of food for other species.
"Although lower numbers of some pest insects might be welcome news, the loss of pollinators, beneficial insects and of food for insect-eaters such as birds and bats will have ecosystem-wide consequences," said David Inouye, an ecologist who wasn't involved in the study.
Inouye, an emeritus professor at the University of Maryland, said the research was remarkable for the length and quality of its observation, which benefited from the help of volunteer "citizen scientists."
BRUSSELS (AP) — Italy on Friday gave crucial support to plans by the European Union to seal a huge free trade deal with five South American nations neighboring Venezuela that has been negotiated for over 25 years.
Italy's Prime Minister Giorgia Meloni was long seen as the key vote in the campaign by European Commission President Ursula von der Leyen to rally support for the trade deal with the Mercosur nations of Brazil, Argentina, Bolivia, Paraguay and Uruguay.
Von der Leyen said the successful vote sends “a strong signal” of the EU's economic clout and stability “in the face of an increasingly hostile and transactional world." She said she would travel to Paraguay soon, where Mercosur nations are meeting next week. The European Parliament will vote on it before it enters into force.
“At a time when trade and dependencies are being weaponized and the dangerous, transactional nature of the reality we live in becomes increasingly stark, this historic trade deal is further proof that Europe charts its own course and stands as a reliable partner,” von der Leyen said.
Italy confirmed its support for the deal on Friday, with Foreign Minister Antonio Tajani hailing it as "good news for Italy.”
“This agreement is destined to boost our exports, with the goal of reaching 700 billion euros ($814 billion) in exports," Tajani wrote in a post on X.
Meloni said she never had “any ideological objections” to the Mercosur agreement.
"We have always said we will be in favor of it when there are sufficient guarantees for our farmers,” she told a press conference on Friday. “The agreement’s potential is good, but not at the expense of the excellence of our products.”
German Chancellor Friedrich Merz said the agreement "is a milestone in European trade policy and an important signal of our strategic sovereignty and ability to act.”
In a statement, he said “with this agreement, we are strengthening our economy and trade relations with our partners in South America — which is good for Germany and for Europe."
The deal would create one of the world's largest free trade zones, covering some 780 million people from Uruguay to Romania and a quarter of the globe’s gross domestic product.
It also gives Brussels a diplomatic win at a time of economic upheaval, providing a stark counterpoint to the gunboat diplomacy of Washington and the coercive export controls of Beijing.
“Given Trump’s policies of isolating the U.S. from the rest of the world, it is an imperative for the EU to lead trade integration policies at the global level and to look for partners elsewhere,” said Antonio Fatas, a macroeconomist at the French business school INSEAD.
On the other side of the Atlantic, Brazil's President Luiz Inácio Lula da Silva celebrated the agreement. His country's economy, worth between $2.3 billion and $2.1 billion last year, is by far the most robust of the South American trade bloc.
“This is a historic day for multilateralism,” Lula said in his social media channels. “In an international scene of growing protectionism and unilateralism, the (EU-Mercosur) deal is a favorable sign for international trade to be a factor for economic growth, with benefits for both blocs.
In the wake of Trumps’ tariff wars, Brussels has sought to curtail its dependency on the U.S. market with trade deals forged across the world. The EU has struck deals with Japan and Indonesia, and are working on one with India.
A delay in December to the signing of the deal had infuriated Lula and led experts to worry a last-minute stumble would wreck the EU's credibility.
“For Europeans, the finalization of free-trade agreements with new partners stands among the best responses to US tariffs, growing protectionism and trade tensions with China,” said Agathe Demarais, a senior fellow at the European Council on Foreign Relations. She said the current EU reliance on China for some critical raw materials could be broken by tapping into Mercosur's deposits.
Opposition to the deal was led by France and Poland, with riled-up farmers flooding streets and blocking roads with tractors from Brussels to Athens. Austria, Hungary and Ireland also voted against it.
Ireland's Prime Minister Micheal Martin said Thursday in Shanghai during a state visit to China that “we don't have confidence that (Irish farmers) wouldn't be undercut by that,” according to Irish public broadcaster RTE.
Both Martin and French President Emmanuel Macron said that internal negotiations sparked by the political furor surrounding the deal had led to reforms that better protect European farmers. But they acknowledged such reforms were not enough to overcome domestic political pressure.
Posting on X on Thursday, Macron said three of France's key demands were now being met: New safeguards to an “emergency brake” of imports if they are found to undercut EU prices by 5% or more; the mirroring of EU food safety regulations in the Mercosur bloc; and an increase of inspections of agrifood imports at EU ports and beyond.
Still, Macron said the potential economic gains of the Mercosur deal are limited and do not justify the risks it poses to EU agriculture. His office stated that the deal would only add 77 billion euros ($89.7 billion) by 2040 — 0.5% of the EU's GDP.
Green members of the European Parliament had vowed to take the Commission to court over the deal. They said the agreement would accelerate deforestation in the Amazon and weaken the EU's climate targets.
Frances Verkamp, trade campaigner at Friends of the Earth Europe, described the deal as “toxic." She said Brussels is "playing a game of imperial dominance in global trade with China and the U.S. that wins nothing for workers or consumers — and even less for nature and climate.”
