Gram‐Negative Bacteria Across Spatial Scales: A Meta‐Analysis of Ant‐Associated Bacterial Communities Under Distinct Environmental Conditions

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Using a meta‐analysis, we estimated the proportion of Gram‐negative (GN) bacteria in ant microbiota across different environments, focusing on habitat and climate influences. Our findings show that ants from temperate regions and arboreal habitats harbor higher proportions of GN bacteria, potentially offering adaptive advantages in variable ...

Landscape and Climate‐Associated Selection in the Native and Widespread Bumblebee, Bombus terrestris

Molecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT Anthropogenic land‐use and climate change pose novel selection pressures on bees, yet their evolutionary responses in terms of morphological or physiological adaptations remain unclear. While adaptive responses are expected, these may be constrained by gene flow when changes in selection pressures are spatially heterogeneous.

Calibration of a suitable enzyme-linked immunosorbent assay (ELISA) for Nilaparvata lugens (stal) antigen detection

浙江大学学报. 农业与生命科学版, 2002
Direct, indirect and double antibody sandwich methods of enzyme-linked immunosorbent assay (ELISA) were examined with the monoclonal antibodies against Nilaparvata lugens (Stal), 3B2 and 4B8, for their ability to detect the antigen of N.

Quantification of Serotonin in Rice and Insect Pest and its Functional Analysis in Insects Using Artificial Diet Feeding

Bio-Protocol, 2019
Rice is one of the world’s most important crops, but its production suffers from insect pests. Rice brown planthopper (BPH; Nilaparvata lugens Stål) and striped stem borer (SSB, Chilo suppressalis Walker) are the two most serious pests in rice production.

Pathways of Amino Acid Degradation in Nilaparvata lugens (Stål) with Special Reference to Lysine-Ketoglutarate Reductase/Saccharopine Dehydrogenase (LKR/SDH).

PLoS ONE, 2015
Nilaparvata lugens harbors yeast-like symbionts (YLSs). In present paper, a genome-wide analysis found 115 genes from Ni. lugens and 90 genes from YLSs that were involved in the metabolic degradation of 20 proteinogenic amino acids.

Differentially Spliced Mitochondrial Cyp419a1 Contributes to Ethiprole Resistance in Nilaparvata Lugens

Insect Biochemistry and Molecular Biology
The brown planthopper Nilaparvata lugens is one of the most economically important pests of cultivated rice in Southeast Asia. Extensive use of insecticide treatments, such as imidacloprid, fipronil and ethiprole, has resulted in the emergence of multiple resistant strains of N. lugens.

Chromosome-level genome assembly from a single planthopper Nilaparvata muiri (Hemiptera: Delphacidae)

Scientific Data
The planthopper Nilaparvata muiri is a sister species to N. lugens (Hemiptera: Delphacidae), a notorious insect pest in Asian rice fields. N. muiri and N. lugens have a different host preference despite the similarities in many biological features.
