The cross-resistance to etofenprox in Nilaparvata lugens with a high adaptability to resistant rice variety IR56.

Pest Manag Sci

January 2025

Key laboratory of Integrated Management of Crop Diseases and Pests (Ministry of Education), College of Plant Protection, Nanjing Agricultural University, Nanjing, China.

Background: The application of resistant rice varieties and insecticides represents two crucial strategies for managing the brown planthopper (BPH), Nilaparvata lugens (Stål). Insects often employ similar detoxification mechanisms to metabolize plant secondary metabolites and insecticides, which poses a potential risk that BPH population adapted to resistant rice may also obtain resistance to some insecticides.

Results: Here in a BPH population (R-IR56) that has adapted to the resistant rice variety IR56 through continuous selection, the moderate resistance to etofenprox was observed.

Does a biological invasion modify host immune responses to parasite infection?

R Soc Open Sci

January 2025

Evolution & Ecology Research Centre, School of Biological, Earth and Environmental Sciences, University of New South Wales, Sydney, NSW 2052, Australia.

Biological invasions can disrupt the close and longstanding coevolved relationships between host and parasites. At the same time, the shifting selective forces acting on demography during invasion can result in rapid evolution of traits in both host and parasite. Hosts at the invasion front may reduce investment into costly immune defences and redistribute those resources to other fitness-enhancing traits.
