Fitness costs of resistance to insecticide pymetrozine combined with antimicrobial zhongshengmycin in Nilaparvata lugens (Stål)

Frontiers in Physiology, 2023
The brown planthopper, Nilaparvata lugens (Stål), is a major pest of rice crops, and its control is critical for food security. Pymetrozine has been recommended as an alternative to imidacloprid for controlling N.

Overexpression of a cytochrome P450 monooxygenase, CYP6ER1, is associated with resistance to imidacloprid in the brown planthopper, Nilaparvata lugens [PDF]

, 2011
The brown planthopper, Nilaparvata lugens, is an economically significant pest of rice throughout Asia and has evolved resistance to many insecticides including the neonicotinoid imidacloprid. The resistance of field populations of N.

Recent advances in molecular biology research of a rice pest, the brown planthopper

Journal of Integrative Agriculture, 2019
The brown planthopper, Nilaparvata lugens Stål, has become a major threat in tropical Asian and China since the rice green revolution of the 1960s. Currently, insecticide application remains the primary choice for controlling this rice insect pest, but ...

Can tropical insects stand the heat? A case study with the brown planthopper Nilaparvata lugens (Stål). [PDF]

PLoS ONE, 2012
The brown planthopper Nilaparvata lugens (Stål) is the most serious pest of rice across the world, especially in tropical climates. N. lugens nymphs and adults were exposed to high temperatures to determine their critical thermal maximum (CT(max)), heat ...

Comparative iTRAQ proteomic profiling of proteins associated with the adaptation of brown planthopper to moderately resistant vs. susceptible rice varieties.

PLoS ONE, 2020
The brown planthopper (BPH), Nilaparvata lugens (Stål), is a destructive pest that poses a significant threat to rice plants worldwide. To explore how BPHs adapt to the resistant rice variety, we analyzed proteomics profiles of two virulent N.
