Grape Phylloxera is the number one threat to grapevines in Australia. Phylloxera (fil-ox-er-a) is a very small, yellow insect that feeds on the roots, and sometimes the leaves, of grapevines. It can also move to the soil surface and up into the canopy and the fruit. A fungal disease that causes black stains to appear on grapevine leaves. Most prevalent in warm and wet conditions Bleeding The phenomenon of sap being expelled from an open pruning wound on the grapevine that often happens during early spring. This is often a sign of good health for the vine.

The physiological response of plants to any stress is often the same , and the challenge to remote sensing is to develop a mapping strategy for vineyards that is based solely on vine response.
Pesticide application is ineffective for phylloxera control, due to the deep rooting zones characteristic of grapevines, and to the high rate of phylloxera reproduction. No effective biological control agent is known.
Intervention practices (more severe pruning, additional irrigation, and fertilization) may serve to lessen phylloxera impact in the short. They program was nicknamed GRAPES Grapevine Remote Sensing Analysis of Phylloxera Early Stress. A slightly later NASA/Ames Ecosystem Science and Technology Branch (ECOSAT) collaboration with Robert Mondavi Winery (Oakville CA) and Wine Grow Consulting (Healdsburg CA) began in to evaluate the technical and economic feasibility of using.
Grapevine phylloxera (Daktulosphaira vitifoliae Fitch) is a significant threat to the Australian viticulture industry, with over 80% of grapevines planted on highly susceptible, ungrafted Vitis Vinifera detection of phylloxera is critical as it can spread unnoticed in the early years of infestation when vine foliar symptoms may not reflect subterranean root damage.
A range of control options exist which could be integrated into an improved management system for grape phylloxera.
Priority areas for future evaluation and further development include early detection techniques, investigation into the use of biological control agents and development of an integrated approach to grapevine phylloxera management. Remote sensing (RS) of biotic stress is based on the assumption that stress interferes with photosynthesis and physical structure of the plant at tissue and canopy level, and thus affects the absorption of light energy and alters the reflectance by: Description of the Pest.
Grape phylloxera is a tiny aphidlike insect that feeds on roots of Vitis vinifera grape and certain rootstocks, stunting growth of vines or killing them. This pest prefers heavy clay soils that are found in the cooler grape-growing regions of the state such as Napa, Sonoma, Lake, Mendocino, and Monterey counties, as well as the Sacramento Delta and the foothills.

The results of projects like GRAPES (Grapavine Remote-sensing Analysis of Phylloxera Early Stress), CRUSH (Canopy for Remote-sensing Uniformly Segmented Harvest) or VINTAGE (Viticultural for Integration of NASA Assessment ot the Grapevine Environment), showed that it is possible to know the soil, microclimate and vegetable material of the vine.
Abstract: The Grapevine Remote sensing Analysis of Phylloxera Early Stress (GRAPES) Project of NASA Ames Research Center measured the effects of the phylloxera root-louse on California vineyards.
Leaf spectral differences were observed with the CASI sensor. Data was correlated by GIS to locate active infestation and predict future spread of. Catchy names like CRUSH (Canopy Remote sensing for Uniformly Segmented Harvest) and GRAPES (Grapevine Remote sensing Analysis of Phylloxera Early Stress) were projects that used remote sensing devices to test the "vigor" (qualities and ripeness of the berries), and detecting the spread of phylloxera infestation.

Remote-Sensing Options. Color infrared photography from aircraft flying above the vineyard is a form of remote sensing that has been in use for decades.
Color infrared film records reflectance in the green and red wavelengths of visible light, and in the near infrared (NIR) range. It does not react to heat or temperature differences in plants.

The morning fog acts as a kind of natural air conditioning and helps make the narrow, mile-long gap in the Mayacamas Mountains below us America's premier wine-grape region.
From the air, Napa Valley is a crazy quilt of fields, scattered small towns, and the occasional estate. Grape phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera Phylloxeridae) is a damaging pest of grapevines (Vitis spp.) around the world, and the management of this pest requires early detection of infestations.
Here, we describe the development and validation of a sensitive DNA test for grape phylloxera that can be applied to soil. Species-specific primers were developed for grape Cited by: As the name implies, the Grapevine Remote-sensing Analysis of Phylloxera Early Stress (GRAPES) project was initiated in response to the grape phylloxera (Daktulosphaira vitifoliae [Fitch]) infestation, which affects a number of California grape-growing regions and is pronounced in the North Coast (California Agriculture March-April ).
The insect (Biotype B) is a form of plant lice that debilitates. 1. Introduction. Recent advances in remote sensed imagery and geospatial image processing using unmanned aerial vehicles (UAVs) have enabled the creation of rapid and ongoing monitoring tools for crop management [1,2,3,4] and the detection/surveillance of insect r, there are still challenges in remote sensing applications, such as detecting early incursions of cryptic Cited by: Grapevine Remote Sensing Analysis of Phylloxera Early Stress project – better known as GRAPES – could buy much-needed time.
The first signs of phylloxera generally appears years after the. Consistent with this idea was the early application of remote sensing in viticulture, which was initially focussed on identification of vineyard areas in California affected by phylloxera (Daktulosphaira vitifoliae; Johnson et al., ).
Thus, vines affected by phylloxera tend to have smaller, more stressed canopies and so areas in imagery Cited by: Grapevine phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera: Phylloxeridae), is an insect pest of Vitis spe-cies.
It has forms that feed on leaves (gallicolae) and roots (radicicolae). On Vitis species native to North America, D. vitifoliae induces galls on leaves and feeds on roots without evident injury.

Weak rootstocks have often failed; strong ones have not. We have no reliable backup management tactics if strong rootstocks were to fail.
We will determine this risk by studying rootstock failures. We will then use weak links in phyl-loxera and associated pathogen biology to develop management tactics and tactics to delay root-stock failure. The seasonal characterization of spatial variability in water requirements across and within vineyards could assist the viticulturist to fine-tune irrigation management for quality optimization.
Remotely sensed crop water stress index (CWSI) is related to crop water status, but it is not known how applicable it is to different grape varieties at different times of the by: Phylloxera was imported to Europe from the northeast United States in the mids, and the root form of this pest devastated European vinifera vineyards growing on their own roots.
Most native American grape species are resistant or tolerant to root feeding, and eventually the European grape industry recovered by replanting vinifera on. To assess how phylloxera feeding and development affected host phenotype, we compared the number of phylloxera to plant physiological and morphological traits.
The number of phylloxera within each gall was not correlated with gall size (R 2 =F =P = ), nightly adaxial CO 2 efflux (R 2 =F =P = ), or adaxial Cited by: Reflectance studies of healthy, maize dwarf mosaic virus-infected, and helminthosporium maydis-infected corn leaves.

Remote Sensing, 11(15), ; doi: /rs . Grapevine phylloxera, Daktulosphaira vitifoliae, is a small (up to 1 mm long) aphid-like insect that lives and feeds exclusively on the roots of grapevines and occasionally in distinctive galls on grapevine leaves.
Phylloxera originates from eastern North America, where it lives on native grapevines. However, the insect is now present in most of the world’s viticultural regions as a result.
