Study a potential ‘game-changer’ for mosquito control
Only female mosquitoes bite and transmit pathogens that cause disease.

Research will enable scientists to eliminate females

New research on sex determination in mosquitoes could have a ‘game-changing impact’ on the control of these pests and other insects, according to scientists at The Pirbright Institute.

It is only female mosquitoes that bite and transmit pathogens that cause disease. As such, scientists believe that the manipulation of the sex determination pathway genes, leading to the elimination of females, could have a profound effect on new approaches to mosquito control.

In a recent study, researchers from the Pirbright Institute identified a male-specific gene in a mosquito that transmits malaria. The gene, named Yob, is necessary for the development of males, but lethal to females if incorrectly activated.

In a new study, researchers will expose the molecules which, besides Yob, are involved in the regulation of early development in both male and female mosquitoes.

Lead researcher Dr Jaroslaw Krzywinski commented: “Better understanding of the components of the pathway is instrumental to the creation of new genetic approaches to controlling mosquito-borne diseases. It will enable us to implement genetic modification technology to cause female lethality or, potentially the reversal of genetic females into males; producing male-only mosquito generations.

“The outputs of this study will also enable identification of the sex determination genes in other insect pests such as Aedes and Culex mosquitoes and will stimulate new avenues of research on their genetic control.”

The research project, “Mechanisms of sex determination in Anopheles and they implementation to control mosquito vectors”, will be funded by the Biotechnology and Biological Sciences Research Council.

Campaign highlights ‘devastating impact’ of smoking around pets

News Story 1
 Leading vet charity PDSA has launched a campaign highlighting the ‘devastating impact’ that smoking can have on pets. The launch coincides with National No Smoking Day (14 March 2018) and aims to raise awareness of the risks of passive smoking and how to keep pets safe.

“Recent studies highlight that this is a really serious issue, and we want pet owners to know that they can make a real difference by simply choosing to smoke outdoors away from their pets,” said PDSA vet Olivia Anderson-Nathan. “We want pet owners to realise that, if they smoke, their pets smoke too.”

AWF named charity of the year

The Animal Welfare Foundation (AWF) has been chosen as charity of the year by the Veterinary Marketing Association (VMA). AWF is a vet-led charity, supported by the BVA, which aims to improve animal welfare though research funding, supporting veterinary education, providing pet care advice and encouraging debate on welfare issues.

VMA has pledged a range of support, including raising awareness and funds at their awards ceremony, which takes place on Friday 16 March, as well as offering marketing support through VMA marketing workshops.
