Oxitec Ltd and its GM mosquitoes – two visitors from Brazil

Oxitec Ltd, the company that developed a self-limited genetically engineered mosquito, has been working with health authorities in Piracicaba, Brazil, in attempt to reduce the population of the Aedes aegypti mosquito, the species that transmits diseases including dengue, chikungunya and Zika. Dengue has been the main mosquito-transmitted disease affecting Piracicaba. Oxitec’s Head of Field Operations, Dr Andrew McKemey, and Dr Pedro Mello, the Secretary of Health for Piracicaba in Brazil, will be in the UK next week and are available to answer any questions you might have about the science behind the GM mosquito, what stage their current mosquito release programme is at, and what the situation is in Piracicaba. Piracicaba City Hall partnered with Oxitec in March 2015 to use the mosquitoes and that programme is now being extended to a larger area of the city. read more

expert reaction to new study on ‘naturally occurring GM butterflies’

A group of researchers have published their work into the transfer of genes between species in nature, and report in the journal PLOS Genetics that the genomes of some species of butterfly have acquired genes from a virus associated with parasitic wasps, some of which they report protect the caterpillar species from infection by a separate virus. read more

expert reaction to study investigating climate change and bumblebee geographical ranges

The pollination of a large proportion of the world’s plants is attributed to bee species, and alterations in the geographical habitats of bumblebees is the focus of a paper published in the journal Science. The authors report differing patterns in terms of the shifting limits of habitat location, including the loss of ranges from southern extremes and movement to higher elevations among southern species. read more

bees and pollution: new research published in Scientific Reports

The decline of the UK’s bee population is rarely out of the headlines, but with discussion often focused on pesticides are there other factors in the environment that might also affect bee behaviour and health? Researchers cam to the SMC to explain their investigation of the impact of common air pollutants in diesel exhaust fumes on the foraging efficiency of honeybees. read more
