The hitchhikers aphids carry within could make them a major biosecurity risk for Australia
Alex Gill Nicholas Bell and Professor Ary Hoffmann Aphids. You might stumble across them in your backyard, snacking on your veggie patch, in fields and orchards where crops are grown and even along roadsides. But this group of sap-sucking bugs are among the most economically damaging pest insects globally. Aphids, like these Green peach aphids, […] -
Breaking Bad bugs: Testing potential biocontrol agents for pesticide tolerance
I have a passion for playing mad scientist with pesticides, all in the name of making agricultural pest control safer and more sustainable. If you’re fond of growing roses, you’re probably familiar with the frustrating critters that invade them in your garden. The critters, in this case aphids, are unfortunately fond of your roses, along […] -

Wolbachia infections in Aedes aegypti: The ‘Bigfoot’ of endosymbionts
Words: Perran Ross Wolbachia are endosymbiotic bacteria found within the cells of many insects, from butterflies and bees to cockroaches and dung beetles. Wolbachia are so common because they often provide their insect hosts with an advantage, aiding their spread through populations. Whether an insect carries Wolbachia is an important question, especially if they’re a […]
