Journal of Asia-Pacific Entomology, 2002
Abstract Annual change in insecticide susceptibility of the long-range migrating rice insects, the brown planthopper (BPH) and the white backed planthopper (WBPH), monitored by topical application was reviewed covering temperate and tropical Asia. Monitoring in Japan revealed consistent increase in topical LD50 of BPH for various insecticides during ...

Brown planthopper infestations alter sugar metabolism in the rice plant as well as brown planthopper
Physiological Entomology, 2021AbstractCarbohydrate plays an important role in rice resistance or tolerance to pests, and also affects the continuous feeding of brown planthoppers (BPHs) on rice. However, the change in the sugar metabolism of BPH and rice plant after BPH infestation is not well studied.

Predator—Planthopper Interactions
1994Parasitoids have been selected often over predators in classical biological control programs because they are generally more host-specific and possess life history traits such as high fecundity, high larval survival, high searching efficiency, short handling time, and low mutual interference, which are thought to be more conducive to pest suppression ...

Characterization of sulfoxaflor resistance in the brown planthopper, Nilaparvata lugens (Stål).
Pest Management Science, 2019BACKGROUND Sulfoxaflor is a new insecticide for controlling Nilaparvata lugens in the field. This study was conducted to investigate the risk of resistance development, the cross-resistance spectrum and the mechanisms of sulfoxaflor resistance in N ...

Rice planthoppers are notorious plant sap‐feeding pests which cause serious damage. While several microbes in rice planthoppers have been broadly characterized, the abundance and diversity of bacteria and fungi in field planthoppers are largely unknown ...

Intra- and Inter-specific Effects of the Brown Planthopper and White Backed Planthopper on Their Population Performance [PDF]
Journal of Asia-Pacific Entomology, 2001 Intra- and inters-specific effects of Nila parvata lugens (Stal) and Sogatella furcifera (Hor vath) (Homoptera: Delphacidae) on their population performances on Indica Zhe 852, Japonica XiuShui 11 and Hybrid XY 9308 were studied in the labora tory. Intra-specific crowding did not influence the performance of N.

Bacterial reproductive manipulators in rice planthoppers
Archives of Insect Biochemistry and Physiology, 2019AbstractRice 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.

How does saliva function in planthopper-host interactions?
Archives of Insect Biochemistry and Physiology, 2019Planthoppers are highly destructive pests that damage rice plants by feeding and transmitting viruses. They feed on phloem sap using specialized mouthparts and secrete saliva during feeding.

Evolution of the planthoppers (Insecta: Hemiptera: Fulgoroidea)
Molecular Phylogenetics and Evolution, 2007The planthopper superfamily Fulgoroidea (Insecta: Hemiptera) comprises approximately 20 described insect families, depending on which classification is followed. Multiple competing hypotheses of fulgoroid phylogeny have been published, based on either morphological character coding or DNA sequence data; however, those hypotheses disagree in several key
