Abstract
Drosophila suzukii, a significant sweet cherry pest, has traditionally been controlled using broad-spectrum insecticides. Various yeasts are known to attract and stimulate flies to feed on yeast-covered surfaces. We investigated an attract-and-kill formulation based on the yeast Hanseniaspora uvarum and the insecticide spinosad, applied to an 80–100 cm wide canopy strip at 1-m height in six field trials across Italy and Germany to manage D. suzukii infestation in cherry. The attract-and-kill formulation, applied at a dose ranging from 21.6 to 34.9 g per hectare of spinosad, according to the training system, decreased the percentage of D. suzukii infested cherries by 41.74–84.26% and the average number of deposited eggs by 79.51–95.56%. The efficacy was comparable to the conventional application of spinosad alone, which was applied at a dose ranging from 84 to 216 g per hectare. The conventional application decreased the percentage of infested cherries by 53.00–92.00% and reduced the number of deposited eggs by 77.10–92.96%. The attract-and-kill technique led to a reduction of up to 90% of insecticide use by targeting the application on limited section of the cherry tree. The targeted approach not only minimized insecticide quantities per hectare, but also resulted in lower residue levels on treated fruits.
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.
