IAN & SPAIN

WELCOME TO MY BLOG. HAVING LIVED IN SPAIN FOR OVER TWENTY YEARS I HAVE TRULY MANAGED TO IMMERSE MYSELF IN THE LOCAL CULTURE AND FEEL TOTALLY INTEGRATED. I WILL BE WRITING ABOUT MY PASSION FOR SPANISH FOOD AND DRINK AS WELL AS ITS CULTURE, PEOPLE AND PLACES OF SPECIAL INTEREST. PLEASE FEEL FREE TO LEAVE A COMMENT.

Genetically-modified olive flies will be released in a Catalan olive grove if a field trial proposed by British biotech company Oxitec is approved in Spain. According to German expert group Testbiotech, which opposes the trial, it would be the first release of GM animals in the European Union. The UK company Oxitec is planning to release genetically engineered olive flies into the environment in Spain (Catalonia) and Italy. The male insects are genetically manipulated in such a way that female descendants will die as larvae. The intention is to reduce the populations of olive flies. The larvae of these insects live inside the olives and can cause substantial economical damage. Oxitec plans to release an unspecified number of its genetically engineered male insects in Spain, near the town of Tarragona. The field trial will be netted to try to prevent the flies from escaping. Similar releases are planned in Italy. The experiments – as far as Testbiotech knows – have not yet been authorised by the national authorities, and it would be the first release of genetically engineered animals in the EU.

“Amongst other things, the trials imply risks for the olive farmers. If the genetically engineered flies escape, the harvest in the regions concerned would become nonmarketable. Genetically engineered larvae living inside the olives are not allowed for food consumption in the EU”, says Christoph Then for Testbiotech. “While the female descendants are supposed to die as larvae, the male individuals can survive for several months, mate and propagate further. If they escape, which according to the application of Oxitec, can not be excluded, they can move into the environment and spread without control. Olive flies are able to fly over distances of several kilometers.”
Currently olive flies are controlled with insecticides, or by using biological means such as insect traps and also irradiated sterile insects. However, the genetically engineered insects, which also inherit the DNA for fluorescent proteins cannot be compared with the irradiated insects. The Oxitec insects are manipulated with synthetic DNA, which is a mix of maritime organisms, bacteria, viruses and other insects. It is not known how these insects will interact with changing environmental conditions, so far they have only been bred in the laboratory.
Christoph Then says: “In 2012 Oxitec approached investors and commercial partners because of the releases now planned in southern Europe. The company also filed several patents on its insects. It is a matter of concern that these trials are driven by commercial interests rather than by finding a way to solve problems with olive flies. From the knowledge we have gained so far we recommend that these applications for environmental release are rejected.“

In my personal opinion I think this is realy scary, to think that we could set loose genetically modified insects into nature with no real way of knowing how this could effect the ecosytem, which it undoubtedly will. Anything genetically modified scares me and you need look no further then the US company Monsanto and see how they are monopolising the US crop sector with their genetically modified seeds. Insect would leave genetically modified lavae in the fruits and it would die inside them and these are the fruits or olives that would later be consumed by humans. I don't know you but I don't want anything genetically modified inside my organism. The worrying factor is that we are probably already eating genetically modified foods and we don't even know it and here we are just discussing flies, but what will be next?

"The field trial will be netted to try to prevent the flies from escaping."
Is that the best that they can do ? Can they guarantee that the flies will agree to stay within the netted area and not try to squeeze under the edges - just like all the bugs that manage to get past our window fly screens. Unfortunately, there is such big money and lobbying involved in the genetics industry that this will probably be allowed to take place.

My thoughts entirely Ray. This is a much more serious problem than people actually think and the problem is when people start to get angry about this and protest it will be too late, there will be no going back as the modified genetic strain would have already integrated in nature. There is no way of knowing how nature will react over time, nor if the fly actually serves a purpose that we haven't identified yet...

It should not be allowed to go ahead. Once the genie is out the bottle..........

Not yet been authorised by national authorities? Then how is this going ahead? Because it's Catalonia?

No it hasn't been approved yet. But with all the money that has been spent there is a great worry that it will be approved. There are multi million euro interests in play here...

Tarragona is a large Roman city on the coast, not a town, as well as a province of Catalunya, I live there, do you know exactly where they will release these flies?

Sorry no idea as of yet, but I will be following the news and if approved will post all information.

Update on this trial has been posted on my blog
