Genetic control and evolution of acoustic signals in planthoppers (Homoptera: Delphacidae)
Population Ecology, 1995AbstractAcoustic signals are part of the specific mate recognition system of planthoppers. The genetic control of acoustic signal characters was studied in the planthopperRibautodelphax imitans. Artificial selection for interpulse interval in the female call revealed a large additive genetic component for this polygenic character.

AbstractPlanthoppers are important worldwide crop pests as well as vectors of numerous diseases. Different species transmitMal de Río Cuarto virus, which causes the most economically important corn disease in central Argentina. Epidemiological studies rely on the accurate identification of the species present in the field.

Rice planthoppers are notorious plant sap‐feeding pests which cause serious damage. While several microbes in rice planthoppers have been broadly characterized, the abundance and diversity of bacteria and fungi in field planthoppers are largely unknown ...

Flight Behaviour in the Brown Planthopper, Nilaparvata lugens (Stål) (Homoptera: Delphacidae) [PDF]
In 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.

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.

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 ...

ABSTRACT. The occurrence of pseudogamous triploid females in populations of the diploid species Ribautodelphax pungens (Ribaut) was studied throughout Europe. Considerable differences in triploid frequencies were found between populations but no regular geographic pattern was discerned.

The white-backed planthopper, Sogatella furcifera (Horváth), causes substantial damage to crops by direct feeding or virus transmission, especially southern rice black-streaked dwarf virus, which poses a serious threat to rice production.

Field studies on rice planthoppers (Horn., Delphacidae) and their natural enemies in Indonesia
Journal of Applied Entomology, 1989AbstractField studies were conducted on rice planthoppers in West Java, Indonesia, during 1985/86 and 1986/87 wet seasons (December‐February).Two pest species, the brown planthopper, Nilaparvata lugens (Stal), and the whitebacked planthopper, Sogatella furcifera (Horvath) were present in both seasons, and two minor species, Sogatodes pusanus (Distant ...

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 ...
