Transgenic rice lines with enhanced resistance to the small brown planthopper
Crop Protection, 2002Abstract Transgenic rice lines containing the snowdrop ( Galanthus nivalis ) lectin gene (GNA) were investigated for the stability of expression of the GNA gene in the sixth (R6) generation. Western blot analysis revealed that GNA was stably expressed among the R6 individual plants at comparable levels with those from their parental lines.

Genetic evidence of transoceanic migration of the small brown planthopper between China and Japan
Pest Management Science, 2022AbstractBACKGROUNDThe small brown planthopper, Laodelphax striatellus (Fallén), is an important pest of rice. It is suspected of migrating over the sea from China to Japan. However, where in China it comes from and how it affects Japanese populations remain unclear.RESULTSHere, we studied the genetic structure of 15 L.

Magnetic fields markedly affect the growth and development of many species of organisms potentially due to cryptochrome and endogenous presence of magnetic materials. Sensitivity to magnetic fields can also be involved in geomagnetic orientation by some long-distance migratory insects.

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.

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 ...

AbstractBacteria symbionts in herbivores play an important role in host biology and ecology, and are affected by environmental factors such as temperature, diet, habitat, antibiotics and so on. However, the effects of antibiotics on the microbiome of the small brown planthopper Laodelphax striatellus (SBPH) remain unclear.

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 ...

New record of small brown planthopper Laodelphax striatellus from Delhi
Indian Journal of Entomology, 2019The small brown planthopper Laodelphax striatellus (Fallen), an important pest as well as vector of rice diseases, is brought out as a new record from the National Capital Region (NCR) Delhi. Recent field surveys in the rice fields of NCR revealed this. Adetailed redescription along with illustrations is provided, along with mtCO1 analysis enabling its

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.

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.
