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 ...

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]
, 1998 Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Planthopper salivary sheath protein LsSP1 contributes to manipulation of rice plant defenses
Nature Communications, 2023 Salivary elicitors secreted by herbivorous insects can be perceived by host plants to trigger plant immunity. Here, the authors show that the small brown planthopper salivary sheath protein LsSP1 binds to salivary sheath proteins and contributes to ...

Food assimilated by two sympatric populations of the brown planthopper Nilaparvata lugens (Delphacidae) feeding on different host plants contaminates insect DNA detected by RAPD-PCR analysis. [PDF]
, 2012 Contamination of insect DNA for RAPD-PCR analysis can be a problem because many primers are non-specific and DNA from parasites or gut contents may be simultaneously extracted along with that of the insect.
