RNA interference of tyrosine hydroxylase caused rapid mortality by impairing cuticle formation in Nilaparvata lugens (Hemiptera: Delphacidae).

Pest Management Science, 2020
BACKGROUND The application of RNA interference (RNAi) technique in controlling agricultural insect pests has been receiving much attention since the discovery of RNAi.

Biology of Delphacodes campestris (Homoptera: Delphacidae)1

Annals of the Entomological Society of America, 1980
In the laboratory, development from egg to adult of the planthopper Delphacodes campestris (Van Duzee) was 31 days for males and 35 days for females, with both sexes undergoing 5 nymphal stages. Longevity of mated females ranged from 18–55 days and egg production ranged from 213–919.

Molecular characterization of insulin‐like peptides in the brown planthopper, Nilaparvata lugens (Hemiptera: Delphacidae)

Insect molecular biology (Print), 2020
Insulin‐like peptides (ILPs) including insulin, insulin‐like growth factor (IGF) and relaxin are evolutionarily conserved hormones in metazoans, and they are involved in diverse physiological processes.

Similarities and spatial variations of bacterial and fungal communities in field rice planthopper (Hemiptera: Delphacidae) populations

Insect Science, 2020
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 ...

Biology of Delphacodes lutulenta (Homoptera: Delphacidae)1

Annals of the Entomological Society of America, 1983
The biology of Delphacodes lutulenta (Van Duzee) was studied in a greenhouse and laboratory under controlled conditions. Eighteen different species or cultivars of plants proved to be host plants; the planthopper produced more progeny on Triticum aestivum L. var. Abe than on any other plant tested. Fifteen females produced an average of 243 progeny per

The distribution and abundance of Delphacidae (Homoptera) in central Argentina

Journal of Applied Entomology, 1999
A 3‐year field study has been carried out on the distribution and abundance of Delphacidae in central Argentina. Insects were collected along a 300 km transect of seven equally spaced sampling sites. At each sampling station there was one sticky trap 6 m above the ground and five sticky traps 1.5 m above the ground.

Radiation Sterilization of Sugar-cane Leafhoppers of the Family Delphacidae

Nature, 1966
WE are at present investigating the possibility of eradicating sugar-cane leafhoppers of the genus Perkinsiella by the sterile male technique as suggested by Knipling1. Insects of this genus are economic pests, because they are the vectors of Fiji disease2 of sugar-cane.

Genome-wide assessment and development of molecular diagnostic methods for imidacloprid-resistance in the brown planthopper, Nilaparvata lugens (Hemiptera; Delphacidae).

Pest Management Science, 2020
BACKGROUND The brown planthopper, Nilaparvata lugens (Stål), is one of the most notorious pests of rice throughout Asia. The brown planthopper have developed high resistance to imidacloprid, a member of neonicotinoid insecticides.
