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 ...

Host‐Associated Bacterial Community Changes After Laboratory Introduction Vary With Wolbachia Presence

Environmental Microbiology, Volume 28, Issue 3, March 2026.
The endosymbiont Wolbachia promotes homogenisation and delays the microbial community response of the parasitic wasp Asobara japonica after a significant environmental change. This suggests that key microbial taxa can mediate community shifts and has important implications for experimental design in microbial ecology, particularly in translating lab ...

Influences of two coexisting endosymbionts, CI‐inducing Wolbachia and male‐killing Spiroplasma, on the performance of their host Laodelphax striatellus (Hemiptera: Delphacidae)

Ecology and Evolution, 2019
The small brown planthopper Laodelphax striatellus (Hemiptera: Delphacidae) is reported to have the endosymbiont Wolbachia, which shows a strong cytoplasmic incompatibility (CI) between infected males and uninfected females. In the 2000s, female‐biased L.

The Zma‐miRNA319‐ZmMYB74 Module Regulates Maize Resistance to Stalk Rot Disease by Modulating Lignin Deposition

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1598-1619, March 2026.
ABSTRACT Stalk rot, primarily caused by Fusarium graminearum (Fg) and Pythium inflatum (Pi), is a major maize disease responsible for significant yield losses. The molecular mechanisms governing defence against these pathogens remain poorly understood. To uncover key miRNAs and their regulatory genes, small RNA, degradome, and transcriptome sequencing ...

Driving by a Publicly Available RGB Image Dataset for Rice Planthopper Detection and Counting by Fusing Swin Transformer and YOLOv8-p2 Architectures in Field Landscapes

Agriculture
Rice (Oryza sativa L.) has long been threatened by the brown planthopper (BPH, Nilaparvata lugens) and white-backed planthopper (WBPH, Sogatella furcifera).

Validation of Reference Genes for Quantitative Real-Time PCR in Laodelphax striatellus

Journal of Integrative Agriculture, 2014
The normalization of quantitative real-time PCR (qPCR) is important to obtain accurate gene expression data, and the most common method for qPCR normalization is to use reference genes. However, reference genes can be regulated under different conditions.

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, Volume 13, Issue 8, 9 February 2026.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

Seasonal fluctuation of small brown planthopper, Laodelphax striatellus FALLEN, and percentage of infective planthoppers in Chikugo, Fukuoka

Kyushu Plant Protection Research, 1968
In 1967, the adult immigration period of the first generation, estimated by the yellow pan water traps, began from about May 20 and continued until about June 20, showing several minor peaks, in seedling beds and early transplanted paddy fields (Fig.1).
