A review of physiological resistance to insecticide stress in Nilaparvata lugens

3 Biotech, 2022
Insecticides are widely used in agriculture as effective means to control pests. However, pests have not been completely mitigated with the increased use of insecticides. Instead, many side effects have arisen, especially the '3Rs' (resistance, resurgence, and residue).

Characterization of a novel superoxide dismutase in Nilaparvata lugens

Archives of Insect Biochemistry and Physiology, 2021
AbstractThe brown planthopper (Nilaparvata lugens) is a major agricultural pest of rice crops. Analysis of the enzymes produced by N. lugens is important to develop pest‐control methods. Superoxide dismutase (SOD) is a detoxification enzyme that catalyzes the conversion of superoxide anions (reactive oxygen species) into oxygen and hydrogen peroxide ...

Characterization of nitenpyram resistance in Nilaparvata lugens (Stål)

Pesticide Biochemistry and Physiology, 2019
Nitenpyram is very effective in controlling Nilaparvata lugens (brown planthopper, BPH), and its resistance has been reported in field populations; however, the resistance mechanism remains unclear. In the present study, cross-resistance and resistance mechanisms in nitenpyram-resistant BPH were investigated.

The influence of temperature on the toxicity of insecticides to Nilaparvata lugens (Stål)

Pesticide Biochemistry and Physiology, 2019
The toxicity of insecticides is associated with a variety of factors including temperature, and global warming is bound to lead to the outbreak of pests; therefore, it is important to study the influence of temperature on insecticide toxicity and pest control.

Are Outbreaks of Nilaparvata lugens (Stål) Associated With Global Warming?

Environmental Entomology, 2010
Outbreaks of the Nilaparvata lugens (Stål), have occurred frequently in China during the past few years, resulting in a broad and significant reduction in rice yield. N. lugens immigrate into China each spring from Southeast Asia, and the Guangxi Zhuang Autonomous Region is the first area affected.

Troponin C is required for copulation and ovulation in Nilaparvata lugens

Insect Biochemistry and Molecular Biology
Troponin C (TnC) is a calcium-binding subunit of the troponin complex that regulates muscle contraction in animals. However, the physiological roles of TnC, especially in insect development and reproduction, remain largely unknown. We identified seven TnC genes encoding four EF-hand motif protein in the rice pest, the brown planthopper Nilaparvata ...

Wing Morphism in the Brown Planthopper, Nilaparvata Lugens

International Journal of Tropical Insect Science, 1980
Changes in the physiological status of the host rice plant had a profound effect on wing morphism in the brown planthopper, Nilaparvata lugens (Stal). Significant increases in macroptery in the hopper progenies reared on senescent or hopperburned hosts occurred mainly because of a general decline in the host’s nutritional status and allelochemic ...

Characteristics of the draft genome of "Candidatus Arsenophonus nilaparvatae", a facultative endosymbiont of Nilaparvata lugens.

Insect science, 2017
There exists a kind of symbiotic bacterium named "Candidatus Arsenophonus nilaparvatae" in the brown planthopper (BPH), Nilaparvata lugens. After being filtered and assembled from the BPH genome sequencing project, the genome sequence of this bacterial symbiont was obtained.

Overexpression of CYP6ER1 associated with clothianidin resistance in Nilaparvata lugens (Stål)

Pesticide Biochemistry and Physiology, 2019
The brown planthopper, Nilaparvata lugens (Stål), is one of the most economically important rice pests in Asia and has become resistant to various kinds of insecticides, including neonicotinoid insecticides. In this study, an N. lugens clothianidin-resistant (CLR) strain and a susceptible (CLS) strain were established, and the potential resistance ...

Pymetrozine activates TRPV channels of brown planthopper Nilaparvata lugens

Pesticide Biochemistry and Physiology, 2019
The commercial insecticide pymetrozine has been extensively used for brown planthopper control in East Asia. The transient receptor potential vanilloid (TRPV) channel, which consists of two proteins, Nanchung (Nan) and Inactive (Iav), has recently been shown to be the molecular target of pymetrozine in the fruit fly (Drosophila melanogaster) and pea ...
