Effect of transgenic Bt rice on dispersal of planthoppers and leafhoppers as well as their egg parasitic wasps

open access: yes浙江大学学报. 农业与生命科学版, 2003
Effects of TT9-3 and TT9-4, which are two homozygous strains of transgenic Bt rice, on the dispersal of planthoppers and leafhoppers as well as their egg parasitic wasps were evaluated in the field.

Dynamical modeling of the control of brown planthoppers by Beauveria bassiana and Cyrtorhinus lividipennis

open access: yesAdvances in Difference Equations, 2019
In this work, the control of brown planthopper, a major pest of rice, when a biological control agent (Cyrtorhinus lividipennis) and a pathogen (Beauveria bassiana) are utilized is investigated mathematically.

Necessity of rice resistance to planthoppers for OsEXO70H3 regulating SAMSL excretion and lignin deposition in cell walls

open access: yesNew Phytologist, 2022
Summary The planthopper resistance gene Bph6 encodes a protein that interacts with OsEXO70E1. EXO70 forms a family of paralogues in rice. We hypothesized that the EXO70‐dependent trafficking pathway affects the excretion of resistance‐related proteins ...

Compatibility of Insecticides with Rice Resistance to Planthoppers as Influenced by the Timing and Frequency of Applications

open access: yesInsects, 2022
Simple Summary The brown planthopper, Nilaparvata lugens (Stål)(BPH) is a pest of rice in Asia. Varietal resistance is proposed as an alternative to insecticides that reduces BPH densities.

Genomics of interaction between the brown planthopper and rice

open access: yesCurrent Opinion in Insect Science, 2017
Rice (Oryza sativa L.) and the brown planthopper (Nilaparvata lugens (Stål)) form a model system for dissection of the mechanism of interaction between insect pest and crop. In this review, we focus on the genomics of BPH-rice interaction. On the side of rice, a number of BPH-resistance genes have been identified genetically.

Effect of insecticide on the population dynamics of brown planthoppers and Cyrtorhinus lividipennis: a modeling approach

open access: yesAdvances in Difference Equations, 2019
In this paper, we investigate the effect of insecticide on the population dynamics of brown planthoppers (a major insect pest of rice) and Cyrtorhinus lividipennis (one of the natural enemies of brown planthoppers) by developing an impulsive mathematical

The molecular mechanisms of silica nanomaterials enhancing the rice (Oryza sativa L.) resistance to planthoppers (Nilaparvata lugens Stal).

open access: yesScience of the Total Environment, 2021
Herein, fluorescent silica (F-SiO2) ENMs (50 nm) were synthesized, which could be taken up and translocated from rice root to shoot, promoting the plant growth and resistance to planthopper compared with Si ion fertilizers under hydroponic conditions ...

The Effectiveness of Lemongrass Oil Against Brown planthopper Nilaparvata lugens Stal. (Hemiptera: Delphacidae) on Rice Plant

open access: yesJTPP: Journal of Tropical Plant Protection, 2021
Rice (Oryza sativa) is the primary food crop in the world. The use of natural pesticides made from essential plants has begun to be developed because it is useful in controlling some plant pests.
