The Genetic Structure of Nilaparvata lugens (Stal.) in Java Populations

Hayati Journal of Biosciences, 2020
The brown planthopper Nilaparvata lugens (Stal.) causes hopperburn in the rice field. The wing macropterous adults of this insect have capability for long distance flight. We aimed to analyze the genetic structure of six N.

Inter-Alpha-Trypsin Inhibitor Heavy Chain 4 Plays an Important Role in the Development and Reproduction of Nilaparvata lugens

Insects, 2022
The brown planthopper, Nilaparvata lugens, is a difficult-to-control insect pest affecting rice yields in Asia. As a structural component of the inter-alpha-trypsin inhibitor (ITI), the inter-alpha-trypsin inhibitor heavy chain (ITIH) has been reported ...

Impact of Abamectin on Anagrus nilaparvatae, An Egg Parasitoid of Nilaparvata lugens

Jurnal Perlindungan Tanaman Indonesia, 2018
Anagrus nilaparvatae (Hymenoptera: Mymaridae) is an egg parasitoid potential for controlling the major pests on rice, the brown planthopper (Nilaparvata lugens [Hemiptera: Delphacidae]).Abamectin is one of insecticides registered for N. lugens. The research was aimed to investigate the impact of contact application of abamectin on the parasitism level ...

Molecular Characterization and RNA Interference Analysis of SLC26A10 From Nilaparvata lugens (Stål)

Frontiers in Physiology, 2022
SLC26A10 is a member of the SLC26 gene family, but its role in insects is still unclear. We cloned the SLC26A10 gene of Nilaparvata lugens (NlSLC26A10) and found NlSLC26A10 contained 11 transmembrane regions and a STAS domain. Expression pattern analysis

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Sensitivity Test of Nilaparvata lugens Stall to Pymetrozine Insecticide

IOP Conference Series: Earth and Environmental Science, 2023
Abstract Brown planthopper (BPH) Nilaparvata lugens Stall is a major pest of rice that often causes outbreaks in several rice production centers in Indonesia. The use of insecticides is still the choice of farmers to control attacks due to weak mitigation efforts in an area.

Chromosome-level genome assembly of the planthopper Nilaparvata muiri

Scientific Data
The Nilaparvata muiri (Hemiptera: Delphacidae) is a sibling species of a destructive rice insect pest, the brown planthopper (BPH), Nilaparvata lugens. Here, we generated a high-quality chromosome-level genome assembly of N.

Studies on active chemicals in the saliva of the rice brown planthopper (Nilaparvata lugens) that elicit the production of rice volatiles

浙江大学学报. 农业与生命科学版, 2005
Active chemicals were found to be present in the rice brown planthopper Nilaparvata lugens head extract that induced rice plants to release volatiles attractive to Anagrus nilaparvatae, an egg parasitoid of N.

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Outbreaks of the brown planthopper Nilaparvata lugens (Stål) in the Yangtze River Delta: immigration or local reproduction? [PDF]

PLoS ONE, 2014
An effective control strategy for migratory pests is difficult to implement because the cause of infestation (i.e., immigration or local reproduction) is often not established.
