Attack of the clones!!! Green peach aphids, Myzus persicae, under a microscope, aren't they cute? But they will come for your crops... beware! If you are having issues with rhem in your garden, think about releasing some beneficials: ladybirds, lacewings, or parasitoid wasps... no spray spring!!!
Aphid location on plants is something that inspired me for this study: doi.org/10.1093/aesa... Pest behaviour is an underrated field that can help us better understand how to coexist with these animals without having to use broad spectrum pesticides that have serious consequences on our ecosystems.
New paper led by @phiddlesticks.bsky.social shows how endosymbionts can affect aphid responses to predators academic.oup.com/aesa/advance...
Changes in the behavior of Myzus persicae (Hemiptera: Aphididae) in response to predators after transinfection with Rickettsiella (Legionellales: Coxiellaceae) endosymbionts
Abstract. Infection with endosymbionts can cause changes in the phenotype of their insect hosts, particularly for life-history traits such as fecundity and

Fieldwork in Australia means unexpected encounters.... it looks soft and the voices in my head go: pet it!
NEW PREPRINT on Aedes vigilax - the Australian saltmarsh mosquito. This mosquito can fly great distances, but there's more to this than initially meets the eye www.biorxiv.org/content/10.1...
Populations of the Australian saltmarsh mosquito Aedes vigilax vary between panmixia and temporally stable local genetic structure
Pest management programs can operate more effectively when movement patterns of target species are known. As individual insects are difficult to track, genomic data can instead be used to infer moveme...

Farmers trial sunn hemp to save cotton crops in Queensland
After years planting cotton, a growing region has built up a soil pest that sucks the life out of crops — but there may be a solution on the horizon.

Energetic shifts predict the mortality of Anopheles gambiae
Life history theory predicts that resource allocation adapts to ecological and evolutionary pressures. We investigated resource and energy dynamics in the malaria vector Anopheles gambiae after exposu...
