As more populations of certain wild species carrying detrimental genes are becoming more widespread, offspring are necessarily dying due to the inheritance of these lethal genes. Some of the more traditional ways of combating this problem are to sterilise the males from a wild population (however, this has potenti ally harmful side-effects in most cases), but another technique is to use radiation (however, this is could be ineffective or even lethal if dosage is not optimal). The sterilisation of males is a specialised method, as it will altogether affect the chosen species. This is on that pointfore much more opportune than pesticides, which are far less specialised, and affect a novelty of different organisms.
An Oxford based fellowship called Oxitec has found a beginning in the form of a fluorescent label. The company Oxitec beginning used this method with a moth-caterpillar, but are promptly targeting a species of mosquito called genus Aedes Aegypti which is a carrier of the viral disease, Dengue. These trials are being carried out in Juazeiro in Brazil.
As there are problems associated with sterilising males, collecting, and releasing them into the wild without harming them, Oxitec has had to look for alternative methods.
The company has found a special protein associated with the flight-muscles in females, which has en opend the company to sustain flightless females. This substance that these females will not be able to mate, and therefore their eggs can be distributed as is necessary. This means that the gene coding for protein for weakened flight-muscles will be passed downward(a) to future generations of females.
However, this technique is not always effective with all species of mosquitoes, as some (carriers of Malaria)have less predictable distributions that other species, for example, Aedes Aegypti, and is therefore harder to capture the desired females.If you want to get a full essay, order it on our website: Orderessay
