Some taxonomic observations on the British Delphacidae (Hemiptera)

Proceedings of the Royal Entomological Society of London. Series B, Taxonomy, 1964
SynopsisThe identity of the genus Delphacodes is discussed and 30 British species formerly referred to that genus are transferred to 12 different genera; of these, two are redefined, each comprised of two subgenera; the characters distinguishing these are given in two keys.

Hybridization studies in the planthopper genus Ribautodelphax (Homoptera, Delphacidae)

Genetica, 1988
Seven known Ribautodelphax species and four recently discovered taxa were crossed. Forty-three percent of the interspecific crosses were successful. Interspecific crosses generally resulted in low numbers of hybrids. In some combinations prolonged larval development of the hybrid males was observed.

Biosystematics of the Muellerianella complex (Homopters, Delphacidae), hybridization studies

Genetica, 1982
Crosses were made between three closely related species of the planthopper genus Muellerianella, M. brevipennis, M. extrusa and M. fairmairei. Most hybrids are produced in crosses between M. extrusa and M. fairmairei. Most of the hybrid females in these crosses and some of the hybrid males are fertile and can be successfully backcrossed with the ...

Genetic control and evolution of acoustic signals in planthoppers (Homoptera: Delphacidae)

Population Ecology, 1995
AbstractAcoustic 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.
