MRCU monitoring population dynamics between two vector species


The Mosquito Research and Control Unit (MRCU) said it’s keeping a close eye on the population dynamics between two species of mosquito capable of transmitting disease.

The MRCU says the Asian tiger mosquito, Aedes Albopictus, is second to the Aedes Aegypti in its efficiency as a vector for disease.

But MRCU Director Dr. Jim McNelly told Cayman 27 the Aedes Aegypti‘s  Albopictus cousins can spread the same diseases like chikungunya, dengue, and Zika.

“What happens if you get rid of the Aedes Aegypti, and you have Aedes Albopictus, and what we are seeing is that once you remove that competition, it looks like Aedes Albopictus might benefit from that,” said Dr. McNelly.

Dr. Mcnelly said the MRCU is still poring over data collected in a five-month trial of Oxitec’s genetically modified mosquitoes in West Bay this year.

GMO mosquito releases were halted this month.
