The diversity of Aussie grasshoppers | Part one
Words: Vanessa White Images: Mike Kearney and Vanessa White Why Australian grasshoppers are fantastic research subjects: The Morabine grasshoppers (subfamily Morabinae) commonly known as “matchstick grasshoppers” are endemic to Australia and comprise 40 genera and around 250 species (Rentz 1996). Both sexes are wingless with a characteristic matchstick-like appearance. Some Morabine species have been studied […]blogs.unimelb.edu.au/pearg/2018/10/08/the-diversity-of-aussie-grasshoppers-part-one

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, […] -
BACK FROM THE BRINK | CROWDFUNDING FOR THE GENETIC RESCUE OF EASTERN BARRED BANDICOOTS
Words: Anne Aulsebrook Cover image: Mount Rothwell Conservation and Research Centre An article published in 1934 describes the flavour of bandicoot stew. ‘After chewing a mouthful I gave up.’ The writer states, ‘The stew tasted like roots. I have not sampled stewed bandicoot since.’ At the time of the article, bandicoots in Australia were already […] -
A new and unusual Wolbachia bacteria from Drosophila flies limited to the female sex
Words: Ary Hoffmann Cover image: Perran Ross As Wolbachia bacteria that live inside insect cells continue to be discovered and studied in detail, our appreciation of the diverse ways in which these bacteria interact with their hosts continues to expand. In past work we have found Wolbachia that cause embryo death when infected males mate […] -

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 […] -
NEW PROJECT | Buruli ulcer
Words and photo: Jason Axford On 26 April at the Peter Doherty Institute, Federal Minister for Health, Greg Hunt, announced new NHMRC funding to investigate the mysterious and rather horrific disease commonly known as Buruli ulcer (BU) (formerly known as Bairnsdale ulcer). The project is led by Prof. Tim Stinear in the Department of Microbiology […]blogs.unimelb.edu.au/pearg/2018/05/10/new-project-buruli-ulcer

Biology of the babushkas
Words: Samantha Ward As the name suggests, at the Pest & Environmental Adaptation Research Group we are interested in pest species and enjoy investigating novel approaches to sustainably control such organisms. I began my PhD at PEARG in 2016 studying parasitoid wasps; A group of wasps that lay their eggs inside or onto other arthropods. […]blogs.unimelb.edu.au/pearg/2018/05/10/biology-of-the-babushkas

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 […]
