Calling signals of seven species and four recently discoverd taxa of the genus Ribautodelphax were recorded and analysed. Clear differences in calling variables were found between all Ribautodelphax studied which suggests that all taxa investigated are true species. Interspecific differences were distinct in males as well as females.

Genetic control and evolution of acoustic signals in planthoppers (Homoptera: Delphacidae)
Population Ecology, 1995Abstract Acoustic signals are part of the specific mate recognition system of planthoppers. The genetic control of acoustic signal characters was studied in the planthopper Ribautodelphax imitans .

The planthopper, Nilaparvata lugens Stål (Homoptera: Delphacidae), uses acoustic signals generated by abdominal vibration and transmitted through rice (Oryza sativa L.) plants to locate mates. The influence of temperature (20, 28, and 32°C) on abdominal vibration patterns of individual females and males, proportion of mated females, and responsivity ...

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 ...

Cell culture of the rice brown planthopper, Nilaparvata lugens Stål (Hemiptera: Delphacidae)
In Vitro Cellular & Developmental Biology - Animal, 2014The rice brown planthopper (BPH), Nilaparvata lugens (Stål), is one of the most destructive insect pests of rice in Asia. Although resistant rice varieties can be effective in managing planthopper populations, BPH has repeatedly been able to overcome resistant rice varieties. It is possible that BPH adaptation to resistant rice varieties may be related

Flight Behaviour in the Brown Planthopper, Nilaparvata lugens (Stål) (Homoptera: Delphacidae)
International Journal of Tropical Insect Science, 1987In order to evaluate the migratory potential of the brown planthopper, Nilaparvata lugens, under as near to normal environmental conditions as possible, adult macropterous insects were captured from the field whilst in the process of flight initiation at the times of their natural take-off peaks.

An orange-eye mutant of the brown planthopper, Nilaparvata lugens (Hemiptera: Delphacidae)
Journal of Asia-Pacific Entomology, 2011An orange-eye mutant of the brown planthopper (BPH), Nilaparvata lugens (Stal), was found in a green house and has since been maintained together with a normal-eye phenotype of BPH in an insectary. The orange color was expressed in all developmental stages of BPH: the eye spots of eggs and the eyes of nymphs and adults of both sexes and wing forms ...

OXALIC ACID AS A SUCKING INHIBITOR OF THE BROWN PLANTHOPPER IN RICE (DELPHACIDAE, HOMOPTERA)
Entomologia Experimentalis et Applicata, 1980Oxalic acid, isolated from leaf sheath extract of rice, has been identified as a potent sucking inhibitor against the brown planthopper. Potassium and sodium oxalate at concentrations of 0.1%–0.2% completely inhibited sucking on a 15% sucrose solution.
