Impacts of rodents in piggeries in Australia – review and pilot impact study

open access: yesPest Management Science, EarlyView.
Rodent impacts in Australian piggeries are under‐researched, with limited data on economic losses and control costs. A review and pilot study found average losses of AUD$100 000 annually. Key concerns include disease, damage, and control expenses.

Reversed impacts by specialist parasitoids and generalist predators may explain a phase lag in moth cycles : a novel hypothesis and preliminary field tests [PDF]

open access: yes, 2013
Among cyclic populations of herbivores, inter-specific temporal synchrony has been attributed to both climatic factors and trophic interactions. In northern Europe, winter and autumnal moths undergo regular 9–11 year population cycles.

Characteristics of fungicide resistance in Asian soybean rust (Phakopsora pachyrhizi) in Paraguay for 2022–2023: insights from genetic mutations and molecular dynamics simulations

open access: yesPest Management Science, EarlyView.
Phakopsora pachyrhizi in Paraguay showed diverse resistance to DMI, SDHI, and QoI fungicides at both regional and intra‐field levels, likely driven by target mutation genes. Abstract BACKGROUND Phakopsora pachyrhizi, the causative agent of Asian soybean rust, poses a major threat to soybean production in South America. The rising incidence of fungicide
