Japanese beetle Popillia japonica Newman: foliar feeding on wine grapes in Virginia
… level for 1985 of the Japanese beetle, Popillia japonica Newman, in the Shenandoah Valley of Virginia failed to reduce berry quality, yield or shoot growth in a commercial vineyard. Intensive postveraison foliage feeding by Japanese beetle resulted 1n fruit with lower soluble solids and …

Interaction Between Insects and Apple (Malus X Domestica Borkh.): Insect Behavior, Genotypic Preference, and Plant Phenolics With Emphasis on Japanese Beetle (Popillia Japonica Newman)
Leaves and fruit of nine apple (Malus x domestica Borkh.) genotypes were evaluated for insect injury in 1998 and 1999. Foliar and fruit injury from 12 insect species was inconsistently affected by genotype. Spraying trees with oil affected neither fruit insect injury nor fruit phytotoxicity. In …

Parasitism of Scarabaeidae by Parasitoid Flies in British Columbia and Western USA: Informing Biological Control Programs Against Popillia japonica with Crowd-sourced Records of Non-target Scarab Beetles
… a population of the invasive scarab beetle Popillia japonica, I used crowd-sourced online data (44,200 observations in BC and Western USA) to determine: scarab species occurrence; which species may be attacked by parasitoid flies; whether any bore eggs that resemble I. aldrichi; and the …

Impact of elevated carbon dioxide and increased temperature on Japanese beetle herbivory
… field conditions. Japanese beetles (Popilla japonica Newman) were enclosed on foliage for 24 hours, after which the beetle survivorship, total and per capita leaf consumption, and leaf protease inhibitor activity was measured. The direct effect of temperature on beetle consumption and …

Aktivierung und Inaktivierung des Cry8C-Toxins von Bacillus thuringiensis japonensis Stamm Buibui im Darmsystem von Engerlingen (Scarabaeidae)
… eine geringe Wirkung, während Anomala-Arten und Popillia japonica empfindlich sind. Zur Identifizierung der Ursachen für die unterschiedliche Wirksamkeit, wurde die Darmphysiologie der Larven von P. japonica und M. melolontha untersucht. Ergebnisse: Das Spektrum der Darmproteasen: Im Darmsaft von …

QTL discovery for Japanese beetle resistance in aphid-resistant germplasm, stacking aphid-resistant genes, and metabolite profiling studies in soybean
… germplasm for resistance to Japanese beetle (<Popillia japonica> Newman), a population was derived from a cross between E06906 (MSU) and another aphid-resistant source, LD05-16060 (Uni. of Illinois) that showed lower susceptibility to Japanese beetle. A QTL (Quantitative Trait Loci) mapping …

Damage-Induced Spatial Heterogeneity of Photosynthesis: Mechanisms and Analysis
… and inhibition of photosynthesis. Herbivory by Popillia japonica and Helicoverpa zea (Boddie) caused a 20--90% increase in transpiration from soybean leaflets without affecting carbon assimilation rates or photosynthetic efficiency (phiPSII). The depression of phiPSII caused by fungal infections …

Interactions of insecticides, entomopathogenic fungi, and earthworms as they relate to white grub IPM in turfgrass systems
… in June. In the greenhouse, Japanese beetle, Popillia japonica Newman females laid a significantly reduced number of eggs in turf treated with lower rate of imidacloprid either applied as a single treatment or as part of a combined treatment compared with untreated control. In an …

The Spatial Trends of Japanese Beetles in Illinois Soybean Fields and Their Effects on Sampling and Production
… the spatial trends of Japanese beetles, Popillia japonica Newman, and to measure their impact on soybean production. Commercial soybean fields were sampled intensively or extensively. Densities and distributions of Japanese beetles within fields were measured with two different sampling …

Impacts of climate change on herbivore induced plant signaling and defenses
… in the leaves affected by Japanese beetle (JB; Popillia japonica) herbivory was greater when plants were grown under elevated CO2, O3 and the combination of both compared to ambient atmosphere. The effect of herbivory on transcription diminished strongly with time, and elevated CO2 interacted …

Pest Management of Japanese Beetle (Coleoptera: Scarabaeidae) and a Study of Stink Bug (Hemiptera: Pentatomidae) Injury on Primocane-bearing Caneberries in Southwest Virginia
Field experiments (2007-2009) and laboratory bioassays (2009) tested the efficacy of insecticides with short pre-harvest intervals, caneberry cultivar susceptibility, and geranium toxicity for reducing Japanese beetle (JB) activity on primocane-bearing caneberries. Deltamethrin, …
