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.

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.

ALARY POLYMORPHISM IN THE SMALL BROWN PLANTHOPPERLAODELPHAX STRIATELLUS(HOMOPTERA: DELPHACIDAE)
Entomologia Experimentalis et Applicata, 1980Environmental and genetic factors which influence alary polymorphism inLaodelphax striatellus(Fallén) were studied. It has been found that alary polymorphism inL. striatellusis determined by quality and quantity of food, and crowding. There is also a clear genetic basis for polymorphism.ZUSAMMENFASSUNGFLÜGELPOLYMORPHISMUS BEILAODELPHAX STRIATELLUS ...
