Higher Fertilizer Inputs Increase Fitness Traits of Brown Planthopper in Rice. [PDF]

open access: yes, 2017
Rice (Oryza sativa L.) is the primary staple food source for more than half of the world's population. In many developing countries, increased use of fertilizers is a response to increase demand for rice.

Influences of chlorpyrifos on antioxidant enzyme activities of Nilaparvata lugens

open access: yesEcotoxicology 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 ...

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.

Uji Ketahanan Galur Padi Terhadap Wereng Coklat Biotipe 3 Melalui Population Build-up [PDF]

open access: yes, 2013
Screening of rice lines resistance to brown planthopper (BPH) through mass screening, filtering line resistance and the population build-up are essential for the release of resistant rice varieties.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

open access: yesInsect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

The Role of Turnera Subulata and Cosmos Sulphureus Flowers in the Life of Anagrus Nilaparvatae (Hymenoptera: Mymaridae) [PDF]

open access: yes, 2018
Anagrus nilaparvatae is a potential egg parasitoid to control the rice brown planthopper (Nilaparvata lugens Stal.) The parasitoid needs to consume suitable food to maximize its biotic potential and parasitizing ability. This study was aimed to determine

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

open access: yesInsects, 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

Double‐Stranded DNA Reduces dsRNA Degradation in the Saliva and Significantly Enhanced RNAi‐Mediated Gene Silencing in Halyomorpha halys

open access: yesAdvanced Biology, Volume 9, Issue 9, September 2025.
The invasive pest Halyomorpha halys causes significant crop losses requiring innovative pest control strategies such as RNA interference (RNAi). However, oral RNAi is largely ineffective in H. halys. This study shows that double‐stranded DNA (dsDNA) stabilizes dsRNA in saliva by inhibiting a highly expressed nuclease.
