Pest Management Science, Volume 82, Issue 4, Page 3853-3873, April 2026.A risk classification of registered pesticides in Brazil was conducted, and the contribution of food to cumulative pesticide exposure was evaluated. Model diets were proposed, based on Brazilian consumption patterns. Abstract BACKGROUND Pesticide residue exposure assessments can be carried out during both the pre‐regulation and post‐regulation phases ...

Ecology and Evolution, Volume 16, Issue 3, March 2026.We generated new genomic resources for the invasion front of fall armyworm in Oceania, confirming that the new invasions conform to the population structure initially identified in Benin. We also identified SNVs associated with insecticide resistance that should be a focus of future tracking of the invasion front and established populations.
