Landscape Diversity and Crop Vigor Influence Biological Control of the Western Grape Leafhopper (E. elegantula Osborn) in Vineyards
This study evaluated how the proportional area of natural habitat surrounding a vineyard (i.e. landscape diversity) worked in conjunction with crop vigor, cultivar and rootstock selection to influence biological control of the western grape leafhopper (Erythroneura elegantula Osborn). The key natural enemies of E. elegantula are Anagrus erythroneurae S. Trjapitzin & Chiappini and A. daanei Tria...
متن کاملSpider and Leafhopper (Erythroneura spp.) Response to Vineyard Ground Cover
Ground cover is used in some vineyards to improve soil structure and help manage insect pests; previous studies have shown lower leafhopper (Erythroneura spp.) densities on vines grown with ground cover. We undertook a 2-yr study to determine why ground cover is associated with reduced leafhopper densities. Ground cover consisted of a fall-planted cover crop of purple vetch (Vicia benghalensis)...
متن کاملInfluence of intensity and duration of regulated deficit irrigation on Erythroneura elegantula (Hemiptera: Cicadellidae) on grape.
We conducted studies in a Paso Robles, CA, grape (Vitis vinifera L.) vineyard in 2002 and 2003 to estimate the impact of regulated deficit irrigation (RDI) intensity and duration on western grape leafhopper, Erythroneura elegantula Osborn. Treatments were based on deficit intensity, 50 and 25% of standard irrigation (moderate and severe deficits, respectively), and deficit duration, 3 or 6 wk t...
متن کاملRegulated deficit irrigation and density of Erythroneura spp. (Hemiptera: Cicadellidae) on grape.
This study looked at regulated deficit irrigation (RDI) on leafhoppers in the genus Erythroneura (Erythroneura elegantula Osborn, or western grape leafhopper, and Erythroneura variabilis Beamer) (Hemiptera: Cicadellidae), which are serious pests of cultivated grape (Vitis vinifera L.) in California. RDI is an irrigation strategy that reduces irrigation during a critical point in the phenology o...
متن کاملBiological Control: Insect Pathogens, Parasitoids, and Predators
Stored product insects cause millions of dollars per year in losses in stored wheat. Traditionally, storedproduct pest management has relied on chemicals to control insects. In some cases, pest management has been improved by applying chemicals only when needed. An increasing effort is being made to reduce or eliminate pesticide residues in the food supply. This trend has increased since the in...
