(CNS): The Cayman Islands Mosquito Research and Control Unit, in partnership with the UK-based firm Oxitec, will be releasing genetically engineered male mosquitoes across Grand Cayman in a new initiative to try and suppress the population of the Aedes aegypti, the mosquito that spreads a number of viruses. Following controversial trials here and in Florida, Cayman joins Brazil in this latest initiative, which will start with a release in West Bay.

The MRCU is planning a multi-phase rollout of what was described as the “Oxitec’s solution” but what are, in fact, genetically modified insects, to help reclaim the island from this disease-carrying pest. In March the World Health Organization (WHO) recommended pilot deployment of the modified insects  because of the Zika crisis and after the US Food and Drug Administration’s (FDA) preliminary findings that there were no significant impacts during a trial in the Florida Keys.

MRCU Director Dr Bill Petrie said it has proven very difficult because fo the size of the island and the currently available tools to eradicate the mosquito and his agency was  looking for new approaches.

“The decision to deploy the Oxitec solution comes after the success of a peer-reviewed trial. We believe this environmentally friendly tool can greatly reduce the population of Aedes aegypti and has the potential to eliminate it from Grand Cayman,” he said.

MRCU performed the world’s first  trial with Oxitec’s OX513A self-limiting mosquito – a genetically engineered, non-biting male that mates with disease-transmitting wild Aedes aegypti females – which successfully reduced the target mosquito population by 96%, officials claimed.

The Sister Islands of Cayman Brac and Little Cayman are not threatened by the diseases carried by the Aedes aegypti because the population there remains below the transmission threshold and the MRCU said the aim is to achieve the same for Grand Cayman.

A deal, which has remained under wraps until today, was signed with the project manager from Oxitec, Dr Renaud Lacroix, on Monday 18 April.

Chief Officer in the Health Ministry, Jennifer Ahearn, who is responsible for the health policy,said, “During the time that we have been planning this project it has unfortunately become all the more urgent, with first chikungunya and now Zika threatening Cayman, the Caribbean and the Americas. Fighting the Aedes aegypti vector and potentially eliminating it from the Cayman Islands, is the surest way to protect our residents and tourists from the dengue, Zika and chikungunya viruses.”

The first phase of the project will include a series of activities to inform the community about the programme. Over two months, Oxitec and MRCU employees will provide information to local residents about the programme, how the solution works and why it is effective.

“Oxitec is very proud of our continuing partnership with MRCU. We have benefited greatly from their expertise both for the original suppression trial and in the process of preparing for the current project,” said Glen Slade, Head of Business Development at Oxitec. “The first trial proved that this approach works, and now we have the opportunity to help protect more people from this mosquito.

“Before we release our mosquitoes, which we refer to as ‘Friendly Aedes aegypti‘, it is important to explain that the males do not bite, do not transmit diseases and do not persist in the environment,” said Dr Lacroix, as he avoided any reference to genetic modification. “Our scientists and staff are delighted to talk about this programme, and will be available to answer questions.”

The next phase will be deployment of the ‘Oxitec solution’ to treat an area with about 1,800 residents in West Bay, and an equivalent area without Oxitec treatment will be used for comparison. Then, subject to appropriate approvals and funding, the goal of the programme is to expand from the northwest end of Grand Cayman, where West Bay is located, across the remainder of the island to reduce Aedes aegypti numbers and help eliminate the diseases they carry.

Although government has only just revealed the plans to the wider public, the West Bay MLAs were informed and met with Oxitec representatives yesterday.

Officials have not yet stated how much the project will cost the Cayman government or if the project is being funded by the Oxford-based private sector firm.

Activities to be conducted by MRCU and Oxitec this week include: Thursday to Saturday, 5-7 May, information booth at the West Bay dock; Saturday 7 May, information Desk at a West Bay, location to be announced; and Thursday to Saturday 5-7 May, house visits in the treatment area.

There will also be a town hall meeting at the John A. Cumber Primary School within the coming weeks.

    This is why Cayman will never advance in any form of science. We will always be stuck in the past due to ignorance of the old. Oh well… when you all are gone, they will be room for new ideas from the younger generation. I guess we’ll just wait, we have time on our side =]

    Ask yourself: in whose flower pot basins, overturned tyres, pop cans and eaves will these domesticated Cayman Islands Aedes Aegypti find the missing tetracycline their offspring will require to survive to Adulthood? Not many I suspect, and very likely zero. With little to no agricultural runoff in Cayman. Just to be absolutely sure, there should be a concurrent ban on any drinking water-based pet or livestock antibiotics from Jun2016-Mar2017. The results of the 2010 releases speak for themselves – a massive reduction in the uniquely-adapted domesticated Aedes Aegypti.

      There are no approved vaccines for Zika, Dengue, or Chikungunya.

      The US CDC states:
      No vaccine exists to prevent Zika virus disease (Zika).
      Prevent Zika by avoiding mosquito bites (see below).
      Mosquitoes that spread Zika virus bite mostly during the daytime.
      Mosquitoes that spread Zika virus also spread dengue and chikungunya viruses.
      http://www.cdc.gov/zika/prevention/index.html

      There is no vaccine available against dengue, and there are no specific medications to treat a dengue infection. This makes prevention the most important step, and prevention means avoiding mosquito bites
      http://www.cdc.gov/Dengue/prevention/

      No vaccine exists to prevent chikungunya virus infection or disease.
      Prevent chikungunya virus infection by avoiding mosquito bites
      http://www.cdc.gov/chikungunya/prevention/index.html

      Help fight Zika, Dengue, and Chikungunya by helping to eliminate mosquito breeding sites. The MRCU has advice on the importance of preventing stagnant water in flower pots, discarded tyres, and other debris. Such water can be used by mosquitoes to breed.

    Short-lived sterile males cannot fertilize the eggs produced by the feeding females. They are shooting blanks. End of story. It won’t be the end of the problem, all it does is (hopefully) reduce the quantity of subsequent generations.

      wrong. GMO mosquitoes produce offspring that die before they reach adulthood. Or should die. some offspring will still survive and pass on their genes

        If they are missing a gene that would otherwise advance them from larva to adulthood, how can they pass along a missing gene (or some new sinister supergene) after their expiration. How does that work?

        Die young like the infant humans born with microcephaly which is supposedly caused by Zika?

        Brazil has done the same experiments with GM mosquitoes and it wasn’t until after these experiments were done that children began to be born with deformities. There could be a link between the GM mosquitoes and the tragic rate of deformed babies in Brazil. How can we be sure there isn’t?

        • Anonymous says:

          Cayman has done these experiments with Oxitec’s GM modified mosquitoes starting in 2009. It wasn’t until after this in January of 2010 that Haiti suffered a devastating earthquake.

          Oxitec trials did not cause the Haiti earthquake any more than they caused the Zika outbreak in Brazil. Correlation does not mean causation. More proof is needed.

          The Oxitec trials in Brazil were done in Jacobina, Bahia state starting in 2014. Zika was already present in Bahia state from 2007. Oxitec trials did not cause Zika virus infections. Zika was already there.

          Zika already existed and was already associated with microcephaly in other countries prior to the Oxitec trials in Brazil. French Polynesia saw a Zika outbreak starting in 2013 associated with a 1 in 100 risk of microcephaly in babies fo women who were infected in the first trimester. Real research was published in The Lancet documenting this association: http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(16)00651-6/abstract

          Oxitec trials did not cause microcephaly. Zika was alreday causing micocephaly prior to Oxitec starting trials.

          But since the Oxitect trials did lower the population of the A egypti mosquito vector it is possible that the Oxitec trials prevented some Zika infections and cases of microcephaly.

    Why mess with the food chain. Birds eat insects as do frogs and chickens. What happens to the food chain when some animals insects / animals are removed from the chain? My guess is at some point the island will be void of all non domesticated animals and wants a country like that.

    Why don’t they provide the results from the first batch they released couple years ago?

      @ Lo-cal,
      While your concern shouldn’t be dismissed lightly, surely you will agree that a perpetual chemical approach is futile, and possibly more hazardous to all other life form (?).

      • lo-cal says:

        I agree that the chemical solution is also not beneficial however there is a natural order of things for a reason.

        Have you ever heard of anyone in Cayman being infected by Dengue or any other mosquito born decease? Is the situation here so pressing that we have to be the guinea pigs for this experiment. Surely there are countries that have chronic problems with this disease but you don’t see them lining up for the experiment.

        In my opinion, all the development going on is rapidly getting rid of the mosquito and other insects anyway. every year i see less and less Soldier Crabs, Land Crabs and snakes. The only thing we cant seem to get rid of is the iguana.

        • Anonymous says:

          @Lo-cal,
          To your question on the infection of Dengue in the Cayman Islands , my answer is ‘No’. However, that does not make you correct in your assumption.

          Perhaps, you could also consider this question – Are there any documented case/s of individual/s becoming ill from chemical exposure as a result of chemicals use to control, or eradicate mosquitos in the Cayman Islands?.. My short answer to this question is also ‘No’.

          I am of position, that it would be reckless to presume that the my two answers (‘No’) to the above questions has settled this matter.

          On your comment, “There is a natural order of things for a reason”. That is myopic at the very least, and a debate for another day.

        • Anonymous says:

          First of all, there is no natural order with the Mosquitos here because they are evasive species. They are originally from North Africa and have been able to spread through out the world. So if we get rid of them it would actually be restoring nature as it once was. Also no animal solely rely on this specific species to survive.

          And yes there has been cases with people who have been infected by the Aedes Aegypti mosquito here. Also we have a very large number of these specific mosquito in westbay and George Town and it’s just best to reduce the population. It’s better to be safe than sorry.

          And to inform you. There is no “development ” that is rapidly getting rid of the Aedes Aegypti Mosquitos to be specific. In fact they are increasing more and more because they are getting very resistant to the pesticides.

          I advise you to read up on this a bit more.

      Well, the mosquito species this is exclusively aimed at are already an introduced species so hopefully the bug-eating animals will have enough ‘native’ mosquitos (if there is such a thing) to live off of. And we native people have less chance of mosquito borne diseases.

    • Anonymous says:

      Aedes Aegypti are a specialised insect pest feeding on humans only, invasive – arriving in Caribbean only a few years ago, domesticated and not part of any native food chain. Their entire life cycle is contained within meters of human dwellings, not in swamps. Results of the peer-reviewed 2010 release in Cayman were published here and all around the world. Search and you will find many articles and scientific journals. You will read that MRCU is leading the planet in the eradication efforts of this pest. With the absence of agricultural runoff in Cayman, we have a fighting chance of exterminating this invasive species from our shores. Cayman will still have far too many of the 6 other types of mosquitos commonly found flying around – those are not domesticated mosquitos, and not the vectors of the diseases we want to keep people safe from.

    • Anonymous says:

      Of the more than half dozen endemic mosquito species of Cayman, Aedes Aegypti and Aedes Albopictus are both invasive pests, arriving just in the last few years. Unlike most mosquito species, they live around homes, not swamps, are not part of any native food chain. They have the capability to carry and rapidly spread dangerous diseases. Everyone can help eliminate these pests by learning about what makes them unique and eliminating habitat around their homes.

          Man has been genetically modifying species for as long as time. A great example is a Mule which is a Donkey and a Horse bred together. They cannot reproduce and would never mate in the wild. Mules were used in Jesus day and were sometime called an Ass…so Jesus may have even rode on one. Fruit trees and other plants have been grafted together to produce hybrid crops for centuries. Plants have been grown in locations they were not naturally occurring and have mutated to match. I think people need to stop listening to their preachers as who as Jesus said Tickled the ears of the flock. People today like to sound smarter than they are so now we use the term Genetically modified. Dog, Horse, Cat, Goat, Sheep, Pig, Cows……breeders have been doing these things since the beginning of time….it’s why GOD gave us a brain in his image…You know the scripture that says…GOD CREATED MAN IN HIS OWN IMAGE. Doing these things are part of that image…And if you really believe in god..imitation is the highest form of flattery.
