Acute toxicity effects of pesticides on beneficial organisms - Dispelling myths for a more sustainable use of chemicals in agricultural environments

This study assesses acute pesticide toxicity on 15 beneficial species, revealing that toxicity varies significantly across species and exposure times, challenging the use of limited representative species in toxicity testing.

'Drifting' Buchnera genomes track the microevolutionary trajectories of their aphid hosts

The paper analyzes Buchnera genome variation across aphid clones to show genetic drift with host evolution, finding no plant host or geographic associations.

Acute toxicity effects of pesticides on predatory snout mites (family Bdellidae)

This study assesses the acute toxicity of 22 pesticides on the predatory snout mite Odontoscirus lapidaria, revealing taxon-specific responses and highlighting the need for broader species representation in pesticide testing.

Ace and ace-like genes of invasive redlegged earth mite: Copy number variation, target-site mutations, and their associations with organophosphate insensitivity

Expanding risk predictions of pesticide resistance evolution in arthropod pests with a proxy for selection pressure

This paper uses pesticide product registrations as a proxy for selection pressure to predict resistance risk in agricultural arthropod pests, showing a positive association between pesticide use and resistance status.

Is what you see what you get? The relationship between field observed and actual aphid parasitism rates in canola crops

The paper compares observed parasitism rates from field mummy counts with actual parasitism rates from laboratory-reared parasitoids in canola crops, finding actual rates are significantly higher than observed.

The effects of insecticide seed treatments on green peach aphid Myzus persicae (Sulzer) (Homoptera: Aphididae) parasitism by Aphidius colemani Viereck (Hymenoptera: Aphidiidae) and predation by Mallada signatus (Schneider) (Neuroptera: Chrysopidae)

This study examines how insecticide seed treatments affect parasitism by Aphidius colemani and predation by Mallada signatus on green peach aphids, finding immediate but short-lived effects on parasitoid fitness.

Taxonomy, distribution and host relationships of aphidiine wasps (Hymenoptera: Aphidiidae) parasitizing aphids (Hemiptera: Aphididae) in Australia grain production landscapes

The paper surveys aphidiine wasps in Australian grain landscapes, identifies key species, and provides a key for identification, highlighting their role in pest management.

Forecasting the potential distribution of the invasive vegetable leafminer using "top-down" and "bottom-up" models

This study predicts the future distribution of the invasive vegetable leafminer in Australia using both process-based and correlative species distribution models.
