}BACKGROUND
Japanese beetle (JB), Popillia japonica Newman, is a severe pest of grapes in the southeastern USA where viticulture is a growing industry. This study evaluated the impact of foliar injury from JB field populations on growth, fruit ripening, berry composition and yield of young vines of six cultivars from vineyard establishment through the first year of production. Three spray regimes, carbaryl applied every 7 or 14 days, or no insecticide, were used to manipulate levels of…

Evaluation of Kaolin Clay as an Alternative Management Tactic for Japanese Beetle Feeding Damage in Grape Vineyards
- Biology
- 2016
Kaolin clay is an alternative, non-insecticide management tactic that can be employed by grape growers to minimize feeding damage by Japanese beetle adults and reduce the amount of conventional insecticide input needed to maintain grape quality.
Japanese Beetle Defoliation Reduces Primary Bud Cold Hardiness during Vineyard Establishment

Insect defoliation could reduce winter hardiness of young grapevines, but such effects have not previously been quantified for field-grown vines. The impact of Japanese beetle (JB) defoliation on…

Assessing the effects of apple cultivar on season-long abundance of adult P. japonica and their defoliation may help growers determine which apple cultivars should be prioritized for scouting and management efforts and provide an estimate of potential biological control by I. aldrichi in agricultural areas in the Midwest.

Several coleopteran foliar feeders are associated with grape in eastern North America. The most important of these is the JB, often responsible for extensive defoliation. This defoliation is very…

Influence of Japanese beetle (Coleoptera: Scarabaeidae) foliar feeding on Seyval Blanc grapevines in Virginia
- Biology
- 1989
In 1985, the natural infestation level of Japanese beetle in the Shenandoah Valley of Virginia failed to reduce fruit quality, yield, or shoot growth in a commercial vineyard, suggesting control measures may not be warranted in some years.
Phenology-Dependent Effects of Foliar Injury and Herbivory on the Growth and Photosynthetic Capacity of Nonbearing Vitis labrusca (Linnaeus) var. Niagara
- Biology
- 2003
Measurements of growth, single-leaf photosynthesis, and whole-vine photosynthesis indicated a higher tolerance to foliar injury late in the season than early in theseason, and measurements of beetle feeding on growth parameters compared to vines injured mechanically indicated qualitatively similar impacts.
Phenological resistance of grapes to the green June beetle, an obligate fruit‐eating scarab
- Biology

Phenological resistance, the use of cultivars that ripen before or after peak pest activity, for reducing injury to grapes by the green June beetle (GJB) (Cotinis nitida), an obligate feeder on soft, ripe fruits is evaluated.
Japanese Beetles Facilitate Feeding by Green June Beetles (Coleoptera: Scarabaeidae) on Ripening Grapes

Assays showed C. nitida generally are unable to bite into intact ripe grape berries, whereas Japanese beetles readily do so, and Phenological resistance, i.e., planting cultivars that ripen after peak flight, could be an effective management strategy.
Role of Feeding–Induced Plant Volatiles in Aggregative Behavior of the Japanese Beetle (Coleoptera: Scarabaeidae)
- Biology
- 1996
The hypothesis that feeding-induced plant volatiles are responsible for aggregation of Japanese beetles, Popillia japonica Newman, on leaves was tested using clonal grape plants and the low number of beetles attracted to vines with nonfeeding beetles or freshly damaged vines provided evidence against the existence of a putative aggregation pheromone.

Establishment and spread of JB throughout fruit-growing regions of the United States is likely to elevate the pest status of GJB and other pests of ripening fruits in vineyards and orchards.

Results indicate that during the establishment phase vines are more tolerant of injury during veraison than during bloom and that foliar injury early in the season can significantly reduce a vine9s ability to tolerate subsequent foliar injuries.
