Italian agronomists show that sustainable maize production is possible without neonicotinoids

In the early 2000s, Italian beekeepers began to report bee mortality events linked to maize sowing. Evidence pointed to three neonicotinoids (imidacloprid, clothianidin, thiamethoxam) and a phenylpyrazole (fipronil) used for seed dressing that were dispersed in the environment during sowing. Following these events and based on the precautionary principle, in September 2008, the Italian Ministry of Health suspended these four active ingredients as maize seed dressing.

De huidige MTR voor clothianidine in het oppervlaktewater is veel te hoog

Het neonicotinoïde insecticide clothianidine is in Nederland toegelaten als middel voor behandeling van zaden van suikerbieten en voederbieten ter voorkomen van schade door insecten. De stof is zeer persistent in de bodem met een halfwaardetijd van 545 dagen, en spoelt bovendien gemakkelijk uit naar het grondwater of komt door afspoeling in het oppervlaktewater terecht.

Vögel leiden unter Insektensterben

Viele Zugvögel kommen jetzt wieder in die oberschwäbischen Gärten zurück – oder sind bereits da. Doch jedes Jahr werden es weniger: Denn mit dem Insektensterben bricht für die meisten Zugvögel die Nahrungsgrundlage weg und auch den Obstbauern fehlen die Insekten. „80 Prozent der Biomasse der Insekten sind in den vergangenen zehn Jahren weggefallen“, sagt Georg Heine vom Naturschutzbund (Nabu) Wangen.

US surface waters are contaminated with neonicotinoid insecticides, with catastrophic effects on the insect world

Data collected by the U.S. Geological Survey (USGS), as part of the Pesticide National Synthesis Project, show that use of neonicotinoids in agriculture rose from about 150 metric tons (all imidacloprid) in the late 1990s and early 2000s to between 510 and 625 tons in 2004. From 2004 to 2007, these figures nearly doubled, and in 2012, according to USGS data, between 2,677 and 2,819 tons were used. Data for 2013 and 2014 are still preliminary but suggest the numbers have continued to rise.

Bird Population Faces Crisis In The Vermont Forest

Vermont is famous for its natural and mesmerizing landscape that includes a big forest. Unfortunately, a recent report has revealed the decrement of the bird population there. ABC News reported a sharp decline of 14.2 percent in the bird population over the last 25 years in the Vermont forest. The latest study has unveiled this crucial fact. Several rare and common bird species exist in the said forest. Among them, some species solely depend on the flying insects and they form a major portion of the bird population.

Im Schrebergarten ist der Gartenrotschwanz selten Zaungast

Der Gartenrotschwanz (Phoenicurus phoenicurus) war noch vor hundert Jahren in der Schweiz weit verbreitet. Doch heute begegnet man dem Singvogel mit dem orangen Schwanz kaum mehr. Dass dieses Gezwitscher selten geworden ist, hat einen guten Grund: Gartenrotschwänze ernähren sich von allerlei Kleingetier, das auf dem Boden und auf Gräsern herumkrabbelt. Von einer Sitzwarte aus, einem Baumstrunk zum Beispiel, suchen die Vögel den Boden ab: nach Käfern, Ameisen, Raupen und Spinnen. Doch haben Düngemittel und Pestizide vielen dieser Bodenkrabbeltiere den Garaus gemacht.

River Irwell suffers serious pollution for the second time in three weeks

The River Irwell appears to have been polluted for a second time in three weeks. Countless fish and insects died following reports a pesticide which was poured down a drain and devastated a 25-mile stretch of the river from Rawtenstall into Manchester city centre earlier this month. Now a second incident has been reported on a section of the Irwell north of Bury. The incident has been reported to the Environment Agency. Mike Duddy, chief executive of the Mersey Basin Rivers Trust, said virtually no river life had survived the previous incident.

Surface waters in the Salinas and Santa Maria regions of California are contaminated with imidacloprid

Surface water monitoring for pesticides in agricultural areas of California is one of the California Department of Pesticide Regulation’s (CDPR’s) key environmental monitoring activities. The Salinas, Santa Maria and Imperial valleys have previously been designated as high priority areas for long-term surface water monitoring due to high pesticide use. This 2013 study is a continuation of the agricultural monitoring project.

Imidacloprid the most frequently detected insecticide in surface waters in eastern Massachusetts during 2009 and 2010

Pesticide occurrence was determined in two suburban surface waters in eastern Massachusetts, USA during 2009 and 2010. Out of 118 collected samples, 45 samples showed detections of one or more target pesticides. Among the herbicides, 2,4-D was the most frequently detected and imidacloprid was the most frequently detected insecticide. Regulatory phaseout of chlorpyrifos and diazinon from residential use by 2004 was reflected in the results by the absence of chlorpyrifos detections and lower detection frequencies of diazinon.

Honeybees encounter danger due to lingering and wandering pesticides

Honeybees -- employed to pollinate crops during the blooming season -- encounter danger due to lingering and wandering pesticides, according to a new Cornell University study that analyzed the bee's own food. Researchers used 120 pristine honeybee colonies that were placed near 30 apple orchards around New York state. After allowing the bees to forage for several days during the apple flowering period, the scientists examined each hive's "beebread" -- the bees' food stores made from gathered pollen -- to search for traces of pesticides.
