Predation of Five Generalist Predators on Brown Planthopper (Nilaparvata Lugens Stål) [PDF]

, 2011
Two generalist predators of brown planthopper,Metioche vittaticollis and Anaxipha longipennis (Gryllidae) have not been much studied in Indonesia. This research was conducted to study and compare the predatory ability of M. vittaticollis, A. longipennis (

Generalist predators function as pest specialists: Examining diet composition of spiders and ladybeetles across rice crop stages

Journal of Applied Ecology, Volume 62, Issue 8, Page 1889-1901, August 2025.
By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

Co-infection of two reoviruses increases both viruses accumulation in rice by up-regulating of viroplasm components and movement proteins bilaterally and RNA silencing suppressor unilaterally

Virology Journal, 2017
Background Synergism between southern rice black-streaked dwarf virus (SRBSDV) and rice ragged stunt virus (RRSV) not only aggravates disease symptoms but also enhances their vector acquisition efficiencies by increasing both viruses’ titers in co ...

Fungicides Reduce the Abundance of Yeast-like Symbionts and Survival of White-Backed Planthopper Sogatella furcifera (Homoptera: Delphacidae)

Insects, 2020
The white-backed planthopper (WBPH) Sogatella furcifera is one of the most harmful pests of rice in Southeast Asia. The fat body of WBPH harbors intracellular yeast-like symbionts (YLS).

Toxins for Transgenic Resistance to Hemipteran Pests [PDF]

, 2012
The sap sucking insects (Hemiptera), which include aphids, whiteflies, plant bugs and stink bugs, have emerged as major agricultural pests. The Hemiptera cause direct damage by feeding on crops, and in some cases indirect damage by transmission of plant ...

A Markov Random Field Model for Image Segmentation of Rice Planthopper in Rice Fields

, 2016
It is meaningful to develop the automation segmentation of rice planthopper pests based on imaging technology in precision agriculture. However, rice planthopper images affected by light and complicated backgrounds in open rice fields make the ...

Non‐coding RNAs in plant stress responses: molecular insights and agricultural applications

Plant Biotechnology Journal, Volume 23, Issue 8, Page 3195-3233, August 2025.
Summary Non‐coding RNAs (ncRNAs) have emerged as crucial regulators in plant responses to environmental stress, orchestrating complex networks that finetune gene expression under both abiotic and biotic challenges. To elucidate this intricate ncRNA crosstalk, this review comprehensively summarizes recent advances in understanding the mechanisms of key ...

Farmer Perceptions and Management of Rice Planthoppers in Cambodia

Japan Agricultural Research Quarterly: JARQ, 2015
Solving big problems requires accurate information. Rice in the area of Cambodia near Vietnam was extensively damaged by the brown planthopper (BPH) from 2007 to 2009, with all districts in Takeo province in the area of Cambodia near Vietnam severely affected. How did farmers learn of methods to protect rice plants?
