Pengaruh cendawan endofit terhadap biologi dan statistik demografi wereng batang cokelat Nilaparvata lugens Stál (Hemiptera: Delphacidae)

open access: yesJurnal Entomologi Indonesia, 2015
Endophytic fungi is an endosymbiont that lives within host plant tissues and does not necessary cause any harm to plants. This type of fungus are important as mediators in plant-herbivore interactions. One of the endophytic fungi in rice is Nigrospora sp.

Regulatory Functions of Nilaparvata lugens GSK-3 in Energy and Chitin Metabolism

open access: yesFrontiers in Physiology, 2020
Glucose metabolism is a biologically important metabolic process. Glycogen synthase kinase (GSK-3) is a key enzyme located in the middle of the sugar metabolism pathway that can regulate the energy metabolism process in the body through insulin signaling.

Psyllid Cysteine Cathepsins Directly Cleave the Outer Membrane Protein BamD of Citrus Huanglongbing Pathogen

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3989-4004, June 2026.
ABSTRACT Candidatus Liberibacter asiaticus (CLas), the causative agent of citrus Huanglongbing (HLB), is transmitted by Asian citrus psyllid, Diaphorina citri; however, the role of the insect's immune effectors in defending against CLas remains poorly understood. This study reveals that D.

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

open access: yesHeterocyclic 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

open access: yesnpj 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 ...

Plant Peptides on the Rise: From Historical Insight to Future Applications

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3777-3802, June 2026.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

Do rice hybrids have heterosis for insect resistance? A study with Nilaparvata lugens (Hemiptera: Delphacidae) and Marasmia patnalis (Lepidoptera: Pyralidae)

open access: yes, 2003
: Antibiosis-based resistance to two insect pests of rice, Nilaparvata lugens (Stal) (Hemiptera: Delphacidae) and Marasmia patnalis Bradley (Lepidoptera: Pyralidae), was compared in 11 F-1 hybrids and their parental lines.

Sulfakinin Signaling Sense Circulating Fructose and Suppresses Food Consumption via Insulin‐Like Peptide in Bactrocera Dorsalis

open access: yesAdvanced Science, Volume 13, Issue 29, 22 May 2026.
This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.
