Abstract

Systena frontalis (Fabricius) is a serious pest in containerized ornamental nurseries affecting >50 plant species, including panicled hydrangea (Hydrangea paniculata Siebold) in the eastern USA. The drench application of cyclaniliprole has proven effective in reducing the emergence of adult S. frontalis from infested containers; however, the effects of winter application and lower rates of cyclaniliprole are poorly understood. Thus, the objectives of this study were to determine the effects of 1) single and repeated drench application of cyclaniliprole in the winter and 2) reduced label rates of cyclaniliprole on the adult S. frontalis emergence and feeding damage in the containerized panicled hydrangea. In the winter of 2023 and 2024, cyclaniliprole was drenched in February, March, and April as a single and repeated application. Three repeated drench applications of cyclaniliprole reduced the emergence of adult S. frontalis by 94–100 % and feeding damage compared to nontreated plants. The emerging adults and feeding damage during February, March, or April were similar to repeated applications, suggesting that a single drench of cyclaniliprole during the winter can effectively reduce adult emergence and is comparable to repeated applications. In addition, results showed that 0.25 × and 0.5 × rates of maximum label rate of cyclaniliprole applied as a drench did not consistently reduce adult S. frontalis emergence and feeding damage on panicled hydrangea as compared to the maximum label rate of cyclaniliprole. Thus, the maximum label rate of cyclaniliprole is needed to manage S. frontalis in ornamental nurseries.

环虫腈对集装箱绣球冬喷施及用量的影响

frontalis （Fabricius）是集装箱观赏苗圃中的一种严重害虫，影响50种植物，包括美国东部的圆锥绣球（hydrangea paniculata Siebold）。经证明，环磷酰胺淋施可有效减少受感染容器中成虫的出现；然而，冬季施用和较低剂量环虫酰胺的效果尚不清楚。因此，本研究的目的是确定1)冬季单次和多次淋施环虫酰胺和2)降低环虫酰胺标记率对集装箱圆锥绣球成虫出苗和取食损害的影响。在2023年和2024年冬季，环aniilprole在2月、3月和4月进行单次和重复施用。与未处理植物相比，三次重复施用环虫腈可使成虫的出苗率降低94 - 100%，并减少取食损害。2月、3月和4月的成虫羽化和取食损害与重复施药相似，说明冬季单次施药可有效减少成虫羽化，与重复施药效果相当。此外，结果表明，0.25倍和0.5倍的环甲酰胺最大标记率与环甲酰胺最大标记率相比，并没有一致地减少成虫的出苗率和对圆锥绣球的取食伤害。因此，在观赏苗圃管理中，需要最大限度地使用环甲酰胺标记率。

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.
