The efforts of scientists to control the dengue causing population of Aedes aegypti mosquitoes by Genetically Modified (GM)male mosquitoes using RIDL (Release of Insects carrying a Dominant Lethal) technology hit a stumbling block as they seems to fail to complete their mission in the presence of tetracycline, an anti biotic. The GM mosquitoes, particularly the male ones carry a genetic regulation that in the absence of antibiotic tetracycline cause death to the larval stage of the off spring there by reducing the Ae.aegypti population. The GM mosquitoes are currently undergoing field trials in Cayman Islands, Malaysia and Brazil with further approvals pending in the United States. An article published by Camilo Rodriguez-Beltran and circulating at the COP-MOP 6 here at the HICC, claims that a confidential report by Oxitec, says that survival rate of the transgenic line rose to 15 percent as the chicken used as food in the experiment is fed on antibiotics such as tetracycline. Actually the survival rate of GM mosquitoes in the absence of tetracycline about 3 per cent. MORE UNI KNR RSA NS2221 NNNN
