Diversity and transmissibility of RNA viruses in the small brown planthopper, <i>Laodelphax striatellus</i>. [PDF]

J Virol
ABSTRACT While a considerable number of viruses have been recently discovered in hematophagous insects, there remains insufficient research on virus diversity and their association with phytophagous insect hosts.

Classification of rice planthoppers based on shape descriptors

The Journal of Engineering, 2019
Here, classification of rice planthopper (RPH) based on shape descriptors was addressed to solve the low semantics problem of shape features in traditional RPH (mainly including the whiteback planthopper (Sogatella furcifera (Horváth)), the brown ...

Description of the immature stages of the planthopper Lacertinella australis (Hemiptera: Delphacidae) [PDF]

, 2014
The five immature stages of the planthopper Lacertinella australis(Remes Lenicov and Rossi Batiz) (Hemiptera: Delphacidae: Saccharosydnini) are described and illustrated. The main characters that al-lowed us to distinguish the various

Investigation of Viruliferous Insect Rate of Planthoppers Captured by Smart Sky Net Trap (SSNT) in Korea during 2015-2017

Research in Plant Disease, 2018
Major viruses infecting rice are transmitted by planthoppers such as small brown planthopper (SBPH), brown planthopper (BPH) and white-backed planthopper (WBPH).

Silencing of two insulin receptor genes disrupts nymph-adult transition of alate brown citrus aphid [PDF]

, 2017
Insulin receptors play key roles in growth, development, and polymorphism in insects. Here, we report two insulin receptor genes (AcInR1 and AcInR2) from the brown citrus aphid, Aphis (Toxoptera) citricidus.

Higher Fertilizer Inputs Increase Fitness Traits of Brown Planthopper in Rice. [PDF]

, 2017
Rice (Oryza sativa L.) is the primary staple food source for more than half of the world's population. In many developing countries, increased use of fertilizers is a response to increase demand for rice.

Unusual characteristics of dicistrovirus-derived small RNAs in the small brown planthopper, Laodelphax striatellus

Journal of General Virology, 2014
In this study, sequences of small RNA (sRNA) libraries derived from the insect vector Laodelphax striatellus were assembled into contigs and used as queries for database searches. A large number of contigs were highly homologous to the genome sequence of an insect dicistrovirus, himetobi P virus (HiPV). Interestingly, HiPV-derived sRNAs had a wide size

Rice Black-streaked Dwarf Virus Preparation and Infection on Rice

Bio-Protocol, 2017
Rice black-streaked dwarf virus (RBSDV), a member of genus Fijivirus in the family Reoviridae, infects rice, maize, barley and wheat, and can seriously affect crop yields. RBSDV is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH)

Fungicides Reduce the Abundance of Yeast-like Symbionts and Survival of White-Backed Planthopper Sogatella furcifera (Homoptera: Delphacidae)

Insects, 2020
The white-backed planthopper (WBPH) Sogatella furcifera is one of the most harmful pests of rice in Southeast Asia. The fat body of WBPH harbors intracellular yeast-like symbionts (YLS).

Rice stripe virus-derived siRNAs play different regulatory roles in rice and in the insect vector Laodelphax striatellus

BMC Plant Biology, 2018
Background Most plant viruses depend on vector insects for transmission. Upon viral infection, virus-derived small interfering RNAs (vsiRNAs) can target both viral and host transcripts.
