An entomologist looked for six years and concluded that five rare Florida butterflies are now extinct.

(Reuters) - U.S. environmental regulators are failing to protect honey bees and their role in pollinating important food crops, and should immediately suspend use of some toxic insecticides tied to the widespread deaths of the bees, a lawsuit filed on Thursday charges.

On Thursday four professional beekeepers and five environmental and consumer groups said they would try to get a court to order the EPA to take action. The groups filed their lawsuit against the EPA in the Northern District Court of California, demanding that the regulatory agency suspend the use of pesticides clothianidin and thiamethoxam.

The pesticides, which are part of a class of systemic insecticides known as neonicotinoids, are absorbed by plants and transported throughout a plant’s vascular tissue, making the plant potentially toxic to insects, the groups said.

Clothianidin and thiamethoxam first came into heavy use in the mid-2000s, at the same time beekeepers started observing widespread cases of colony loses, leaving beekeepers unable to recoup their losses, they said.

“Beekeepers and environmental and consumer groups have demonstrated time and time again over the last several years that EPA needs to protect bees. The agency has refused, so we’ve been compelled to sue,” said Peter Jenkins, a lawyer for the Center for Food Safety who is representing the coalition of plaintiffs.

The groups said they have obtained records that show several “legal violations” by EPA officials connected to the approvals for clothianidin and thiamethoxam products.

The case also challenges the EPA’s use of “conditional registrations,” which expedite the approval process for chemical companies seeking to bring new products to market. Since 2000, over two-thirds of pesticide products, including clothianidin and thiamethoxam, have been brought to market as conditional registrations, the groups said.

I don’t see the suit being won, but will be interesting to follow during 2013.

Solid reporting on this one.

Superweeds, Superpests: The Legacy of Pesticides

“The rapid adoption of a single weed-killer for the vast majority of crops harvested in the United States has given rise to superweeds and greater pesticide use, a new study suggests. And while crops engineered to manufacture an insect-killing toxin have reduced the use of pesticides in those fields, the emergence of newly resistant insects now threatens to reverse that trend.

Farmers spray the herbicide glyphosate, widely sold under the Monsanto brand Roundup, on fields planted with seeds that are genetically engineered to tolerate the chemical. Found in 1.37 billion acres of corn, soybeans, and cotton planted from 1996 through 2011, this “Roundup Ready” gene was supposed to reduce or eliminate the need to till fields or apply harsher chemicals, making weed control simple, flexible, cheap, and less environmentally taxing.

In fact, this system has led farmers to use a greater number of herbicides in higher volumes, according to the study, published this week in the peer-reviewed journal Environmental Sciences Europe.”

“As the region has warmed since the 1980s, some of these species have added an extra generation during the summer for the first time on record in that location.

Among the 263 species already known to have a second or third generation there during toasty times, 190 have grown more likely to do so since 1980, Altermatt reports online December 22 in Proceedings of the Royal Society B.

Only a rough third or so of all the species Altermatt reviewed show the capacity to breed more than once a year. What warming is probably doing for them, he speculates, is jolting the insects’ overwintering form into action early and also speeding up insect development. These head starts may allow time for a bonus generation before a non-temperature cue, autumnal day length, plays its role in shutting down insects for winter.

“From a pest perspective it’s an important issue,” says population ecologist Patrick Tobin based in Morgantown, W.Va., for the Forest Service Northern Research Station. Tobin has studied a warmth-related extra generation in a North American pest, the grape berry moth. He points out that an extra surge of attacking pests in the growing season means yet another headache, expense and round of damage for farmers.”

France has asked the European regulators to suspend the authorization to plant Monsanto’s genetically modified (GM) MON810 corn. France’s ecology minister says the decision is based on studies showing GM crops “pose significant risks for the environment.”

Agence France-Presse reports:

The request is “based on the latest scientific studies” which show that the use of the GM crops “pose significant risks for the environment,” the ministry said in a statement.

The ministry pointed to a recent study by the European Food Safety Authority (EFSA) that raised concerns with another form of GM crop, BT11, that it said could also be applied to MON 810.

“If the European Union does not act, we can invoke the safeguard clause” which allows EU nations to independently restrict or prohibit the sales of products, it said.

President Nicolas Sarkozy in November pledged to seek new legal measures after the European Court of Justice and France’s top administrative court overturned a French ban on GM crops from US agriculture giant Monsanto.

France tv info writes that six countries in the EU also ban the cultivation of genetically modified corn: Germany, Hungary, Greece, Luxembourg, Austria et Bulgaria.
