Insight into phenotypic plasticity in planthoppers

Current Opinion in Insect Science, 2023
Planthoppers possess an impressive ability to exhibit phenotypic plasticity, which allows them to adjust their morphology for migration, overwintering, and adaptation to different environmental conditions. The wing and color polyphenism are the two most outward morphologies.

Pesticide-Induced Planthopper Population Resurgence in Rice Cropping Systems.

Annual Review of Entomology, 2020
Planthoppers are serious rice pests in Asia. Their population resurgence was first reported in the early 1960s, caused mainly by insecticides that indiscriminately killed beneficial arthropods and target pests.

Dual oxidase-dependent reactive oxygen species are involved in the regulation of UGT overexpression-mediated clothianidin resistance in the brown planthopper, Nilaparvata lugens.

Pest Management Science, 2021
BACKGROUND Uridine diphosphate-glycosyltransferases (UGTs) are phase II metabolic enzymes involved in metabolism of toxins and resistance to insecticides in insect pests.

Current susceptibilities of brown planthopper Nilaparvata lugens to triflumezopyrim and other frequently used insecticides in China

Insect Science, 2020
The brown planthopper is a notorious rice pest in many areas of Asia. The evolution of insecticide resistance in Nilaparvata lugens has become a serious problem in the effective control of this pest in the paddy field.

Sequential sampling: planthoppers in rice

Crop Protection, 1986
Abstract A sequential sampling plan was developed for the brown planthopper, Nilaparvata lugens Stal, and the whitebacked planthopper, Sogatella furcifera Horvath in rice. The plan was tested in several different areas in the Philippines and compared with a more intensive sampling technique.

Rice Resistance to Planthoppers and Leafhoppers

Critical Reviews in Plant Sciences, 2012
For over 50 years, host-plant resistance has been regarded as an efficient method to reduce yield losses to rice caused by delphacid and cicadelid hoppers. Already a number of resistant rice varieties have been developed and deployed throughout Asia. To date, over 70 hopper resistance genes have been identified in rice; however, less than 10 genes have

REARING OF PLANTHOPPERS ON A HOLIDIC DIET

Entomologia Experimentalis et Applicata, 1971
Planthoppers and leafhoppers (Delphacidae and Deltocephalidae) were reared on a holidic diet for eight generations. On the holidic diet, nymphal stages were prolonged, but they became shorter after the fourth generation. The resulting adults showed no difference in sizes compared with the controls.

A Flatid Planthopper, Metcalfa pruinosa1

Journal of Economic Entomology, 1961
Observations on the lire history of a f1atid planthopper, Metcalfa pruinosa (Say), were made in the Lower Rio Grande Valley of Texas. Photographs of various stages are included. Eggs were found to hatch during March. Adults were first observed during May. Only one generation each year was found from 1956 through 1960.

Antibiotic exposure perturbs the bacterial community in the small brown planthopper Laodelphax striatellus

Insect Science, 2020
Bacteria symbionts in herbivores play an important role in host biology and ecology, and are affected by environmental factors such as temperature, diet, habitat, antibiotics and so on.
