Diversity in New World Stenocranine Planthoppers (Hemiptera: Delphacidae)

Transactions of the American Entomological Society, 2009
ABSTRACT. The diversity of stenocranine planthoppers and their reported host plants is reviewed and discussed with particular reference to the New World fauna. A new species of Obtusicranus and two new genera (Frameus n. g. with 5 new species, Tanycranus n. g. with 1 new species) are described and illustrated.

Field studies on rice planthoppers (Horn., Delphacidae) and their natural enemies in Indonesia

Journal of Applied Entomology, 1989
AbstractField 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 ...

Influence of crop husbandry on rice planthoppers (Hemiptera; Delphacidae) in the Solomon Islands

Agro-Ecosystems, 1974
Abstract Husbandry practices which led to the rice planthoppers Nilaparvata lugens Stal and Sogatella furcifera Horv. (Hemiptera; Delphacidae) becoming severe pests at Ilu on Guadalcanal are identified. In the system of two irrigated rice crops a year at Ilu, rice was grown in every month of each year from 1960 to 1966. Overlapping of an extended

A revision of the planthopper genus Chionomus Fennah (Hemiptera: Fulgoroidea: Delphacidae)

Zootaxa, 2020
The planthopper genus Chionomus Fennah, 1971 (Hemiptera: Fulgoroidea: Delphacidae) currently includes three Neotropical species, removed from the polyphyletic genus Delphacodes Fieber, 1866. Morphological and molecular evidence further redefine Chionomus to include ten additional species (eight species removed from Delphacodes, two described as new ...

A molecular framework for the identification of planthopper vectors (Hemiptera: Delphacidae) of central Argentina

Bulletin of Entomological Research, 2015
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.

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.
