Lab-reared mosquitoes maintain their lust for blood
Words and images: Perran Ross Modified mosquitoes raised in laboratories are being released into the wild in disease control programs. These mosquitoes will still bite you, but they’re less capable of transmitting the viruses that cause dengue fever, Zika and more. This antiviral effect is caused by infection with a bacterium called Wolbachia, which occurs […]blogs.unimelb.edu.au/pearg/2019/11/07/lab-reared-mosquitoes-maintain-their-lust-for-blood

Sterile mosquito release leads to 80% population knock-down in Singapore
The National Environment Agency of Singapore released Wolbachia infected male mosquitoes last April in order to suppress the local population. The field study has been a fantastic success with an 80% population reduction achieved in the last nine months. Ary is a member of Singapore’s Dengue Expert Advisory Programme, providing expertise and guidance for the […] -
Marking mosquitoes
Words: Mengjia Liu Images: Perran Ross and Mengjia Liu It is important to study the fitness of different colonies of Wolbachia-infected mosquitoes, and also of interest to test fitness effects within the same colony when mosquitoes are maintained under different conditions. As we have been maintaining uninfected mosquitoes under laboratory conditions for over 25 generations, […] -
Probing the void for blood
Words and video: Perran Ross I recently filmed one of our mosquito colonies trying desperately to reach my arm through their enclosure. The video has been posted on Reddit by a third party and received enormous attention with over 4.5 million views in its first nine hours. To make the video, I held my arm […]blogs.unimelb.edu.au/pearg/2018/07/10/probing-the-void-for-blood

Large male mosquitoes unluckier in love
Words and images: Perran Ross Large male mosquitoes may have more trouble than smaller males in finding a partner. In a new study, we find that small female mosquitoes tend to avoid larger males, preferring to mate with smaller ones. In this study, now available as a pre-print on bioRxiv, we performed laboratory experiments to […]blogs.unimelb.edu.au/pearg/2018/05/31/large-male-mosquitoes-unluckier-in-love

New publication | Fine-scale landscape genomics helps explain the slow spatial spread of Wolbachia through the Aedes aegypti population in Cairns, Australia
Author summary and figures by Tom Schmidt Wolbachia is a bacterium that suppresses the capacity for arbovirus transmission in the mosquito Aedes aegypti, and can spread spatially through wild mosquito populations following local introductions. Recent introductions in Cairns, Australia have successfully established Wolbachia in the Ae. aegypti population, but the infection has spread more slowly than expected […] -
Ambiguous literature | kdr triple resistance mutation – Where has it really been found?
Editors note: This article is direct from our internal research diary Words: Nancy M. Endersby-Harshman The purpose of this article is to recommend very careful reading and analysis of the literature relating to sodium channel mutations in Aedes aegypti and equal care in writing about them. I have uncovered some confusion in the mosquito literature […] -
Collecting fresh mosquitoes | PEARG in the field
Words: Tom Schmidt Photos: Tom Schmidt and Perran Ross At PEARG, we have a great interest in environmental pests and how to deal with them. One of these pests is the mosquito Aedes aegypti, which causes catastrophic damage throughout the world’s tropical zone. Aedes aegypti spreads viruses such as dengue, Zika and chikungunya, and is […]blogs.unimelb.edu.au/pearg/2018/04/30/collecting-fresh-mosquitoes-pearg-in-the-field
