摘要

气候变化引起的温度升高可能会促进害虫向新的地区传播,这就需要调整害虫管理策略。铜基杀菌剂广泛应用于葡萄栽培中防治真菌病害,但也可能对非目标害虫产生影响。本研究在模拟当前(2002-2021年)和未来(2081-2100年)气候情景下,研究了波尔多混合药剂对葡萄害虫botrana Lobesia产卵行为和卵存活的影响。通过实验室选择实验和无选择实验来评估波尔多混合剂的产卵偏好、潜在威慑作用及其对卵的毒性。在选择实验中,在两种气候条件下,植物分枝杆菌雌性对未经处理的葡萄均表现出显著的偏好。然而,在无选择实验中,波尔多混合物在两种情况下都没有显著阻止产卵,也没有影响卵的孵化率。虽然波尔多混合物对产卵行为的影响很小,但未来的气候条件显著降低了雌性的寿命和繁殖力。这种繁殖产量的减少可能表明有害生物压力降低,但在较温暖的条件下,加速的世代更替和增加的伏虫性可能在长期内放大有害生物压力。该研究提供了在未来气候情景下波尔多混合物对L. botrana的附带效应的见解,并强调需要进一步研究其对其他关键生活史性状(如发育,繁殖)的潜在影响。这些发现强调了将气候变化预测纳入虫害管理战略以确保可持续葡萄栽培做法的重要性。

Current and future perspectives on Lobesia botrana pest oviposition behavior in the context of climate change and fungicide applications

Current and future perspectives on Lobesia botrana pest oviposition behavior in the context of climate change and fungicide applications
Climate change-induced temperature increases are likely to promote the spread of insect pests into new regions, requiring adaptations in pest management strategies. Copper-based fungicides are widely used in viticulture to manage fungal diseases, but may also impact non-target insect pests. This study investigated the effects of Bordeaux mixture on the oviposition behavior and egg survival of the grapevine pest Lobesia botrana, under simulated current (2002–2021) and future (2081–2100) climatic scenarios. Laboratory choice and no-choice experiments were conducted to assess oviposition preferences, potential deterrent effects of Bordeaux mixture, and its toxicity to eggs. In the choice experiment, L. botrana females showed significant preference for untreated grapes under both climatic conditions. However, in the no-choice experiment, Bordeaux mixture neither significantly deterred oviposition nor affected egg hatching rate in either scenario. While Bordeaux mixture had minimal influence on oviposition behavior, future climatic conditions significantly reduced female longevity and fecundity. This reduction in reproductive output may suggest lower pest pressure, but accelerated generation turnover and increased voltinism under warmer conditions could amplify pest pressure in the long term. This study provides insights on the collateral effects of Bordeaux mixture on L. botrana under a future climatic scenario and emphasizes the need for further research on its potential impacts on other key life history traits (e.g., development, reproduction). These findings highlight the importance of integrating climate change projections into pest management strategies to ensure sustainable viticultural practices.

期刊介绍: The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
