No. Aedes aegypti is the species of mosquito which is primarily responsible for spreading dengue. Also, only female mosquitoes can spread dengue or chikungunya.  Males do not bite or spread disease (in fact males cannot bite). Other Aedes species such […]

We’ve introduced a gene into the mosquitoes which stops their cells from functioning normally, and this only affects the mosquito. The self-limiting gene is able to tie up the normal processes in an insect cell and as a result, the […]

A

There were no human impacts reported in Cayman, Panama and Brazil field trials. The bite of an Oxitec female mosquito is the same as a wild one because the proteins of the two introduced genes (pest control gene and colour […]

Oxitec is pioneering a new solution to control harmful insect populations, including the mosquito species Aedes aegypti which spreads Dengue Fever and Chikungunya. According to the Centers for Disease Control and Prevention, approximately 100 million people each year suffer from […]

Wolbachia are bacteria that live within insect cells and are passed from one generation to the next through the insect’s eggs. Wolbachia is present in up to 60% of all the different species of insects. However Wolbachia is not naturally […]

The Sterile Insect Technique (SIT) is a method of insect control that involves irradiating the insect with ionizing radiation from toxic isotopes such as Cobalt 60. Although SIT has proven an effective technique to control some agriculturally important insect pests, […]

A

Yes. Oxitec and its collaborators have performed open field release tests of Oxitec’s Aedes aegypti (under permit from the regulators) in several countries (including the Cayman Islands, Malaysia and Brazil) from 2009.  In each trial aimed at suppressing the native […]

Insecticides kill insects and they can be very effective. In agriculture the use of insecticides has been enormously beneficial to farmers and has contributed to greatly increased food quantity and quality.
In health, the situation is different. Insecticides can only […]

Dengue fever is a severe, flu-like illness that affects infants, young children and adults. There is neither specific medicine nor vaccine for dengue fever. Dengue fever is transmitted by the bite of an Aedes aegypti mosquito infected with any one […]

Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It causes fever and severe joint pain. Other symptoms include muscle pain, headache, nausea, fatigue and rash.
The disease shares some clinical signs with dengue, and can be misdiagnosed […]

No, we don’t believe this to be practical or indeed possible. Aedes aegypti originates from Africa and has spread around the world largely through human transport (sea freight, airplanes etc.) and now infests urban areas right across the world. Our […]

A

No, Aedes aegypti mosquitoes cannot produce viable offspring with other insects in the wild, not even with other species of mosquito. Therefore the genes are restricted to this single species of mosquito. Animals that eat the OX513A Aedes aegypti mosquito […]

A

All Oxitec insects and their offspring contain a fluorescent protein that can be seen using a special light. In OX513A this can be seen at the larval stage.  The colour marker is an important part of our approach. Through this […]

A

Mutation can occur in insects, so it’s worth considering what would happen in the highly unlikely event that there was a mutation that made the self-limiting gene ineffective.
We regularly check the genetic make-up of our mosquitoes, approximately every 7 […]

A

As with all methods of controlling insects, there is always a small chance that resistance could develop. But the chance is much smaller with our solution than conventional pesticides. That’s because when pesticides are sprayed in the wild, mosquitoes will […]

A

Yes. Once the released males have mated with a wild female, they will not survive beyond their short lifespan of less than a week.  Females that have mated an Oxitec male lay eggs which hatch into larvae, but the larvae […]

A

In the laboratory where reared in ideal conditions, a very small number of larvae (up to 5%) can survive to adulthood but in the wild, this is extremely unlikely. But even if they did, this would not be a problem […]
