ON THE GRAPE LEAFHOPPERS IN KYUSHU
Kyushu Plant Protection Research, 1963 Erythroneura apicalis, NAWA (nom. jap. Futaten-hime-yokobai) has been known as only one Japanese species of grape leafhopper. In 1961, however, one of the authors recognized another leafhopper, Erythroneura suzukii MATS. (nom. jap. Suzuki-hime-yokobai), attacking grape leaves in Fukuoka district. This may be a new record of damage caused by the species,

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge
Insect Science, EarlyView.Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Insect Science, EarlyView.This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Surveying: Leafhopper populations [PDF]
California Agriculture, 1965 Rapid and accurate surveying for grape leafhopper population levels is essential to a decision for necessity of insecticide treatment within an integrated pest control program. These Tulare County studies indicate that counting the nymphs on only two leaves per acre gives as accurate an estimate of the population as did counting the nymphs on fifty ...

Journal of Applied Entomology, EarlyView.ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

Plant Breeding, EarlyView.ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.
