Novel but stable endosymbionts have contrasting effects on aphid dispersal and plant feeding damage in the cereal pest Diuraphis noxia

This study shows that introducing novel endosymbionts into the aphid Diuraphis noxia alters its dispersal ability and plant feeding damage, with Rickettsiella increasing damage and Regiella reducing it.

New genomic resources for an invasive mite pest expand the known diversity of pesticide resistance mechanisms and guide development of KASP diagnostic markers

This paper presents a chromosome-level genome and genomic dataset for the invasive mite Halotydeus destructor, identifies pesticide resistance mutations, and develops KASP markers for resistance diagnostics.

The ecological and economic benefits of sustainable agricultural practices: Evidence from on-farm trials in broad-acre grain crops

This study evaluates the ecological and economic benefits of sustainable agricultural practices through on-farm trials in Australia, finding similar yields and profits between conventional and sustainable methods while supporting biodiversity.

Spread of a single superclone drives insecticide resistance in Acyrthosiphon kondoi across an invasive range

The paper identifies a superclone driving insecticide resistance in Acyrthosiphon kondoi across its invasive range through genomic and functional analyses.

A persistent bacterial Regiella transinfection in the bird cherry-oat aphid Rhopalosiphum padi increasing host fitness and decreasing plant virus transmission

This study transinfected the bird cherry-oat aphid with Regiella insecticola, enhancing host fitness and reducing plant virus transmission.

The endosymbiont Rickettsiella viridis increases the virulence of Diuraphis noxia but reduces alate frequency

The redlegged earth mite draft genome provides new insights into pesticide resistance evolution and demography in its invasive Australian range

The paper presents the first reference genome of the redlegged earth mite, identifying genes associated with pesticide resistance and population structure in its invasive range.

Genome-wide SNPs of vegetable leafminer, Liriomyza sativae: insights into the recent Australian invasion

The paper uses ddRAD-seq SNP data to analyze the genetic origin and invasion history of Liriomyza sativae in Australia, finding connections to the Torres Strait, Bali, and Papua New Guinea.
