An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

Pest Management Science, Volume 82, Issue 3, Page 2694-2707, March 2026.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

Synthesis of novel meta-diamide compounds containing pyrazole moiety and their insecticidal evaluation

Heterocyclic Communications
A novel series of meta-diamide compounds incorporating a pyrazole moiety (2a–2v) were designed and synthesized based on cyproflanilide. Their structures were validated through 1H NMR, 13C NMR, and HRMS analyses.

Microbiome variation correlates with the insecticide susceptibility in different geographic strains of a significant agricultural pest, Nilaparvata lugens

npj Biofilms and Microbiomes, 2023
Microbiome-mediated insecticide resistance is an emerging phenomenon found in insect pests. However, microbiome composition can vary by host genotype and environmental factors, but how these variations may be associated with insecticide resistance ...

Climate Change Can Generate Enemy‐Free Space for Crop‐Feeding Herbivores

Global Change Biology, Volume 32, Issue 3, March 2026.
Magnitude and direction of change in parasitoid pressure for 14 agricultural pests subject to climate‐driven distributional shifts. Pests are organized per increasing parasitoid pressure under current climatic conditions (X axis). Bubble size is reflective of the (absolute) area affected by a given pest under a given scenario.

Influences of chlorpyrifos on antioxidant enzyme activities of Nilaparvata lugens

Ecotoxicology and Environmental Safety, 2013
The brown planthoppers (Nilaparvata lugens, BPH) resistant to chlorpyrifos were selected in laboratory for eight generations. In the full course, the successive changes of activities of SOD, CAT and POD were analyzed. The analyses revealed that increasing of LD50 value was parallel to increasing of SOD, CAT, and POD, all of which increased gradually ...

High migratory potential of fall armyworm in West Africa despite stable temperatures and widely available year‐round habitats

Insect Science, Volume 33, Issue 1, Page 313-324, February 2026.
Despite the minimal annual temperature variation and the widespread distribution of potential year‐round habitats in Ghana, the migratory potential of the local fall armyworm remains strong and is indistinguishable from that of the fall armyworm in China, which undergo seasonal migration.

Transcriptional Response of ATP-Binding Cassette (ABC) Transporters to Insecticide in the Brown Planthopper, Nilaparvata lugens (Stål)

Insects, 2020
The ATP-binding cassette (ABC) transporter superfamily is one of the largest groups of proteins and plays a non-negligible role in phase III of the detoxification process, which is highly involved in the response of insects to environmental stress (plant

Emerging Viral Threats in Rice: A Decade of Discovery and Implications for Crop Protection

Plant, Cell &Environment, Volume 48, Issue 12, Page 8702-8711, December 2025.
ABSTRACT Rice viral diseases pose severe threats to global food security, with over 20 viruses identified in China alone. The advent of high‐throughput sequencing has accelerated the discovery of novel viruses in cultivated and wild rice, unveiling previously undetected threats.

Pancreatic triglyceride lipase is involved in the virulence of the brown planthopper to rice plants

Journal of Integrative Agriculture, 2020
The brown planthopper (BPH), Nilaparvata lugens, an important rice insect pest, can enhance its virulence to BPH-resistant rice within as short a span as several generations.
