Life history responses of the small brown planthopper Laodelphax striatellus to temperature change
Journal of Thermal Biology, 2023Temperature is a key environmental factor in ectotherms and influences many life history traits. In the present study, the nymphal development time, sex ratio and wing dimorphism of the small brown planthopper Laodelphax striatellus were examined under the conditions of constant temperatures, naturally varying temperatures (or different generations ...

Male Killing Caused by a Spiroplasma Symbiont in the Small Brown Planthopper, Laodelphax striatellus
Journal of Heredity, 2013Spiroplasma-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 ...

The small brown planthopper (Laodelphax striatellus) as a vector of the rice stripe virus
Archives of Insect Biochemistry and Physiology, 2022AbstractThe small brown planthopper, Laodelphax striatellus, is a destructive pest insect found in rice fields. L. striatellus not only directly feeds on the phloem sap of rice but also transmits various viruses, such as rice stripe virus (RSV) and rice black‐streaked dwarf virus, resulting in serious loss of rice production.

Musashi orchestrates melanism in Laodelphax striatellus
Insect ScienceAbstractIn insects, melanism, a fundamental pigmentation process, is of significant importance in evolutionary biology due to its complex genetic foundation. We investigated the role of the RNA‐binding gene Musashi (msi) in melanism in Laodelphax striatellus, a Hemiptera species. We identified a single L.

The brown planthopper (BPH, Nilaparvata lugens), the small brown planthopper (SBPH, Laodelphax striatellus), and the white-backed planthopper (WBPH, Sogatella furcifera) are problematic insect pests and cause severe yield losses through phloem sap-sucking and virus transmission.

Abstract Several forms of carboxylesterase were observed in a malathion-resistant small brown planthopper, Laodelphax striatellus Fallen, by isoelectrofocusing. To study the mechanisms of increased esterase activity, esterases were purified and their biochemical characteristics were investigated in five active esterase isozymes of two resistant ...

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 ...

Lethal and sublethal effects of sulfoxaflor on the small brown planthopper Laodelphax striatellus
Journal of Asia-Pacific Entomology, 2016Abstract Laodelphax striatellus (Fallen), as an important pest of gramineous crops, has developed resistance to multiple classes of insecticides, impairing control efficiency. However, the application of insecticides is still the main control measure for it.

Wolbachia are the most common symbionts in arthropods; antibiotic treatment for eliminating the symbionts from their host is necessary to investigate the functions. Tetracycline antibiotics are widely used to remove endosymbiont Wolbachia from insect hosts.
