Characterization of nitenpyram resistance in Nilaparvata lugens (Stål)
Pesticide Biochemistry and Physiology, 2019Nitenpyram 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.

Characterization of a novel superoxide dismutase in Nilaparvata lugens
Archives of Insect Biochemistry and Physiology, 2021AbstractThe 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 ...

Molting-related proteases in the brown planthopper, Nilaparvata lugens
Insect Biochemistry and Molecular Biology, 2023Digestion and absorption of old cuticles during insect molting are necessary for new cuticle formation, during which complicated enzyme catalysis is essential. To date, a few carboxypeptidases, aminopeptidases and serine proteases (mostly trypsins) connected with cuticle digestion, zymogen activation and histological differentiation during the ecdysis ...

Contribution of UDP-glycosyltransferases to chlorpyrifos resistance in Nilaparvata lugens
Pesticide Biochemistry and Physiology, 2023As a multigene superfamily of Phase II detoxification enzymes, uridine diphosphate (UDP)-glycosyltransferases (UGTs) play important roles in the metabolism of xenobiotics including insecticides. In this study, 5-nitrouracil, an inhibitor of UGT enzyme activity, effectively increased the toxicity of chlorpyrifos to the chlorpyrifos-resistant strain of ...

Effects of triflumezopyrim on the reproduction of brown planthopper, Nilaparvata lugens
Journal of Asia-Pacific Entomology, 2021Abstract The brown planthopper, Nilaparvata lugens Stal (Hemiptera: Delphacidae), is a notorious pest on rice in Asia and has evolved serious resistance to traditional chemical insecticides in recent years. Triflumezopyrim, a newly commercialized mesoionic insecticide, exhibited an excellent control effect on sucking insects, including N.

Wing Morphism in the Brown Planthopper, Nilaparvata Lugens
International Journal of Tropical Insect Science, 1980Changes 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 ...
