Bacterial reproductive manipulators in rice planthoppers

Archives of Insect Biochemistry and Physiology, 2019
AbstractRice planthoppers (Hemiptera: Delphacidae) are notorious pests for rice (Oryza sativa) in Asia, posing a serious threat to rice production and grain security. Rice planthoppers harbor diverse bacterial symbionts, including Wolbachia, Cardinium, Spiroplasma, and Arsenophonus, which are known to manipulate reproduction in arthropod hosts.

Chromosomal‐level genomes of three rice planthoppers provide new insights into sex chromosome evolution

Molecular Ecology Resources, 2020
The brown planthopper Nilaparvata lugens, white‐backed planthopper Sogatella furcifera, and small brown planthopper Laodelphax striatellus are three major insect pests of rice. They are genetically close; however, they differ in several ecological traits

Efficacy of Benzpyrimoxan 10SC Against Rice Planthoppers

Indian Journal of Entomology, 2022
The efficacy of foliar application of benzpyrimoxan 10SC @ 50, 75, 100, 125 and 150 g a.i./ ha besides the insecticidal checks imidacloprid 17.8SL @ 25 g a.i./ha and buprofezin 25SC @ 187.5 g a.i./ha was evaluated against the brown planthopper (BPH) Nilaparvata lugens (Stal.) and the white backed planthopper (WBPH) Sogatella furcifera (Horvath) on rice

Sequential sampling: planthoppers in rice

Crop Protection, 1986
Abstract A sequential sampling plan was developed for the brown planthopper, Nilaparvata lugens Stal, and the whitebacked planthopper, Sogatella furcifera Horvath in rice. The plan was tested in several different areas in the Philippines and compared with a more intensive sampling technique.

Evolution and functional analysis of odorant-binding proteins in three rice planthoppers: Nilaparvata lugens, Sogatella furcifera, and Laodelphax striatellus.

Pest Management Science, 2019
BACKGROUND The white-backed planthopper (WBPH) Sogatella furcifera, the brown planthopper (BPH) Nilaparvata lugens, and the small brown planthopper (SBPH) Laodelphax striatellus are three notorious rice pests that cause annual losses in rice yield ...

A novel negative thermotaxis behavior in rice planthoppers is regulated by TRPA1 channel.

Pest Management Science, 2020
BACKGROUND In the field, we observed that many white-backed planthoppers (Sogatella furcifera, WBPH) stayed at the top region of rice plants exposed to direct sunshine. It was known that WBPH frequently took flight when the ground temperature is about 25°

Current understanding of the molecular players involved in resistance to rice planthoppers.

Pest Management Science, 2019
Rice planthoppers are the most widespread and destructive pest of rice. Planthopper control depends greatly on the understanding of molecular players involved in resistance to planthoppers.

Rice Resistance to Planthoppers and Leafhoppers

Critical Reviews in Plant Sciences, 2012
For over 50 years, host-plant resistance has been regarded as an efficient method to reduce yield losses to rice caused by delphacid and cicadelid hoppers. Already a number of resistant rice varieties have been developed and deployed throughout Asia. To date, over 70 hopper resistance genes have been identified in rice; however, less than 10 genes have

Pesticide-Induced Planthopper Population Resurgence in Rice Cropping Systems

Annual Review of Entomology, 2020
Planthoppers are serious rice pests in Asia. Their population resurgence was first reported in the early 1960s, caused mainly by insecticides that indiscriminately killed beneficial arthropods and target pests. The subsequent resurgence involved two mechanisms, the loss of beneficial insects and insecticide-enhanced planthopper reproduction.
