Evaluation of interception traps for capture of Xylotrechus arvicola (Coleoptera: Cerambycidae) in vineyards varieties from Protected Denomination of Origin León

Abstract

Xylotrechus arvicola (Coleoptera: Cerambycidae) is a pest in vineyards (Vitis vinifera) in the main Spain wine-producing regions with Protected Denomination of Origin (PDO). The action of the larvae, associated to the spreading of wood fungi, causes damage especially in important varieties of V. vinifera. X. arvicola females lay eggs concentrated in cracks or under the rhytidome in the wood vines, which allows the emerging larvae to get into the wood and make galleries inside the plant being then necessary to prune intensively or to pull up the bored plants (1). The objective of the study was to evaluate captures of X. arvicola insects in five varieties of V. vinifera in PDO León. In 2022, trapping experiments were conducted in the wine-producing region of Spain (PDO León) in five varieties of V. vinifera (Tempranillo, Prieto Picudo, Albarín, Mencía and Verdejo), using interception traps (CROSSTRAP®) with a ethanol (2), in a completely randomized design. The traps were checked every few days and the number of mean adults captured in traps were compared using one-way ANOVA followed by Fisher´s LSD post-hoc test (P<0.05). The greatest days of insects captures were from 1-June to 13-June (25 in Tempranillo, 26 in Prieto Picudo, 21 in Albarín, 17 in Mencía and 6 in Verdejo). Tempranillo and Prieto Picudo varieties had more insects captured per trap (2.75 and 2.66 insects, respectively) during all the evaluation period in the vineyards, significantly different from insects captured per trap in Albarín variety (1.83 insects), Mencía variety (1.58 insects) and Verdejo variety (0.66 insects). Tempranilloand Prieto Picudo were the varieties more attacked by X. arvicola. The first days of June were capture the highest number of X. arvicola adults.

INTEGRAPE guidelines and tools: an effort of COST Action CA17111

INTEGRAPE was a European interdisciplinary network for “data integration to maximize the power of omics for grapevine improvement” (CA17111, https://integrape.eu/), funded by the European COST Association from September 2018 to 2022. This Action successfully developed guidelines and tools for data management and promoted the best practices in grapevine omics studies with a holistic future vision of: “Imagine having all data on grapevine accessible in a single place”.

The weak role of organic mulches in shaping bacterial communities in grapevine

The interest in sustainable and ecologic agricultural practices in grapevine has grown significantly in recent years in the context of ecological transition. Organic mulches are treatments that support the circular economy and positively affect the soil and the plant. They are an alternative to herbicides and other conventional practices since they may influence soil moisture, erosion, structure and weed control. However, their effects on the soil and must microbiota remain unknown.

Impact of polyclonal selection for abiotic stress tolerance on the yield and must quality traits of grapevine varieties

The effects of climate change in viticulture are currently a major concern, with heat waves and drought affecting yield, wine quality, and in extreme cases, even plant survival. Ancient grapevine varieties have high intravarietal genetic variability that so far has been explored successfully to improve yield and must quality. Currently, there is little information available on intravarietal variability regarding responses to stress. In the current work, the intravarietal genetic variability of several Portuguese varieties was studied for yield, must quality, and tolerance to abiotic stress, through indirect, rapid, and nondestructive measurements carried out in the field.

Irrigation frequency in four grapevine red varieties in Spain. Effect on must volatile composition

The irrigation water management in the vineyard is a crucial aspect to obtain sustainable quality production over time. Previous studies have set the water requirements to be applied in the vineyard at 30 % of the reference evapotranspiration (ET0), although there are no studies that settle the effects of the frequency of irrigation application on red varieties in Spain. The present study contemplates the application of deficit irrigation (30 % ET0) applying a weekly dose in a single irrigation (T07) or in two irrigation events (T03) per week. The study has been carried out in 2021-2022 with four red varieties in different Spanish wine regions: Garnacha Tinta (Badajoz), Tempranillo (Valladolid), Syrah (Albacete) and Mencía (Lugo). The effects of irrigation frequency on must volatile composition have been evaluated through GC-MS.

Extreme vintages affect grape varieties differently: a case study from a cool climate wine region

Eger wine region is located on the northern border of grapevine cultivation zone. In the cool climate, terroir selection is one of the foundations of quality wine making. However, climate change will have a significant impact on these high value-added vineyards. This study presents a case study from 2021 and 2022 with the investigation of three grape varieties (Kadarka, Syrah, Furmint). The experiment was conducted in a steep-sloped vineyard (Nagy-Eged hill) with a southern exposure.
