Screening of Brown Planthopper Resistant miRNAs in Rice and Their Roles in Regulation of Brown Planthopper Fecundity

Rice Science, 2022
MicroRNAs (miRNAs) can participate in plant-insect interactions, which regulate plant defense networks. In this study, we analyzed the miRNA expression profiles of six rice varieties before and after brown planthopper (BPH)-feeding. We identified 45 differentially expressed miRNAs between BPH- susceptible and BPH-resistant rice varieties and 144 miRNAs

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

Advances 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

Adaptation by the Brown Planthopper to Resistant Rice: A Test of Female-Derived Virulence and the Role of Yeast-like Symbionts

Insects, 2021
The adaptation by planthoppers to feed and develop on resistant rice is a challenge for pest management in Asia. We conducted a series of manipulative experiments with the brown planthopper (Nilaparvata lugens (Stål)) on the resistant rice variety IR62 ...

Response of planthoppers to novel margin management in arable systems

, 2007
Planthoppers (Hemiptera: Auchenorrhyncha) form one of the most abundant groups of phytophagous above-ground invertebrates in agroecosystems. Planthoppers have potential as a useful indicator of the effects of management in agroecosystems due to their ...

Notes on Immigrant Delphacid Planthoppers in Hawaii (Homoptera: Fulgoroidea) [PDF]

, 1990
Immigrant delphacid planthoppers which have become established in Hawaii since 1960 are discussed, and a revised key to Hawaiian Delphacini (sensu Zimmerman 1948) is ...

The snapping organ likely evolved once in the planthoppers.

, 2019
(A) Systematic distribution of the snapping organ (green, Fulgoromorpha) indicates a single origin at the root of planthopper phylogeny. White spaces within planthoppers indicate modification of snapping organs in the non-Asiracinae delphacids and the ...

Testing Seven Hypotheses to Determine What Explains the Current Planthopper (Fulgoridae) Geographical and Species Richness Patterns in China

Insects, 2020
Although many hypotheses have been proposed to understand the mechanisms underlying large-scale richness patterns, the environmental determinants are still poorly understood, particularly in insects.

Blue Light Receptor PHR2‐Mediated Spectrum Antiviral Immunity

Advanced Science, EarlyView.
Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

Pest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...
