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.

Cold-water dip to raise funds for Vetlife

News Story 1
 The veterinary mental health charity Vetlife is inviting the veterinary community to join it for a sponsored cold-water dip.

The event will take place at Walpole Bay, Margate, on 17 May during Mental Health Awareness Week. Participants of all abilities can join in the challenge and are advised to bring a towel, a hot drink, a snack, and warm clothes to get changed into afterwards.

Those taking part are being asked to try to raise £100 each to support the work of the charity.

Details about how to take part can be found here

Bluetongue low vector period ends

In an update to its bluetongue guidance, the Department for Environment, Food and Rural Affairs (Defra) has announced that the seasonal low vector period for the disease has ended.

With winter over, Defra is planning for a possible increase in cases as midges become more active. It has warned that farms along the east coast of England from Norfolk to Kent, and along the south coast from Kent to Devon, are at highest risk from infected midges blown over from northern Europe.

Since the virus was detected in England in November 2023, there have been 126 confirmed cases. The most recent case to be confirmed was on 1 March 2024.

Farmers are asked to continue to frequently monitor their livestock and ensure their animals and land are registered with the Animal and Plant Health Agency.
