Male Killing Caused by a Spiroplasma Symbiont in the Small Brown Planthopper, Laodelphax striatellus

Journal of Heredity, 2013
Spiroplasma-mediated late male killing was found in the small brown planthopper, Laodelphax striatellus. Female-biased colonies (maternal lines, N = 4) were established from planthoppers collected in Taiwan and Japan. This sex ratio distortion was maternally inherited (sex ratio of total number of progenies [female:male]: 488:0 in F1, 198:7 in F2, 407 ...

ARGONAUTE SUBFAMILY GENES IN THE SMALL BROWN PLANTHOPPER, Laodelphax striatellus (HEMIPTERA: DELPHACIDAE)

Archives of Insect Biochemistry and Physiology, 2015
Argonaute (AGO) proteins are essential catalytic components of the RNA‐induced silencing complex and play central roles in RNA interference. Using a combination of bioinformatics and rapid amplification of cDNA ends (RACE) methods, putative AGO subfamily members, ls‐AGO1 and ls‐AGO2, were cloned and characterized from the small brown planthopper ...

Optimal use of insecticide against the small brown planthopper, Laodelphax striatellus, effectively reduces the damage caused by Rice stripe virus.

Plant Disease
Rice stripe virus disease is one of the most devastating diseases of rice (Oryza sativa) in East Asia. The causal virus, Rice stripe virus (RSV), is persistently transmitted by the small brown planthopper (Laodelphax striatellus, SBPH). Since there is no

Application of a dual-loop double-stranded RNA to control small brown planthopper.

Insect Science
RNA interference, induced by double-stranded RNA (dsRNA), has emerged as a biopesticide for pest control. However, the stability of dsRNA remains a challenge in topical delivery, preventing widespread agricultural application.

Insecticidal and synergistic activity of dsRNAs targeting buprofezin-specific genes against the small brown planthopper, Laodelphax striatellus.

Archives of Insect Biochemistry and Physiology, 2020
The small brown planthopper, Laodelphax striatellus, is a dangerous pest in rice fields. Although buprofezin has been used to control L. striatellus for more than a decade, the occurrence of buprofezin-resistant L. striatellus has been recently reported.

Organ-specific transcriptome response of the small brown planthopper toward rice stripe virus

Insect Biochemistry and Molecular Biology, 2016
Rice stripe virus (RSV) causes rice stripe disease and is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH) in a persistent, circulative, and propagative manner. The alimentary canal and salivary gland of SBPH play important roles in viral replication and transmission.

High temperature determines the ups and downs of small brown planthopper Laodelphax striatellus population

Insect Science, 2012
AbstractSmall brown planthopper, Laodelphax striatellus (Fallén) numbers usually drop sharply in the summer and revive quickly in the autumn. However, it is unclear whether and how the high temperature plays a role in this process. The effects of durations of heat exposure (33°C) on life‐history traits were examined here.

Allozyme Polymorphism and Geographic Variation in the Small Brown Planthopper, Laodelphax striatellus (Homoptera: Delphacidae)

Biochemical Genetics, 1997
The small brown planthopper, Laodelphax striatellus, immigrates annually into Japan over the East China Sea from the Asian mainland. It is not known whether this long-distance dispersal has any effect on the genetic structure of Japanese L. striatellus populations. The dispersal of L.

Effect of Rice Sowing Date on Occurrence of Small Brown Planthopper and Epidemics of Planthopper-Transmitted Rice Stripe Viral Disease

Agricultural Sciences in China, 2009
To understand the relationship between rice sowing date and occurrence of the rice small brown planthopper (SBPH) Laodelphax striatellus Fallen and the epidemics of the planthopper-transmitted rice stripe viral (RSV) disease, four sowing dates of rice were evaluated in 2006 and 2007. The results showed that the peak density of SBPH and RSV incidence in
