Abstract

The spirea aphid Aphis citricola Van der Goot is a serious fruit trees pest in China. Sulfoxaflor is a novel sulfoximine insecticide that has been widely used to control sucking insect pests. This study aimed to investigate the transgenerational sublethal effects of sulfoxaflor on the biological traits and metabolic enzymes activities of A. citricola. Our results showed that sublethal concentrations of sulfoxaflor (LC10 and LC20) significantly reduced the adult longevity and fecundity of the F0 generation. Furthermore, the development time of the first instar nymph and the pre-adult of F1 generation were significantly prolonged. The total prereproductive period (TPRP) and the mean generation time (T) of the F1 generation were also significantly extended. Consequently, the fecundity, intrinsic rate of increase (rm), and finite rate of increase (λ) of the F1 generation were significantly diminished. Additionally, the activities of cytochrome P450 monooxygenases (P450) and carboxylesterase (CarE) in A. citricola were enhanced following treatment with sublethal concentrations of sulfoxaflor, indicating their involvement in the detoxification of sulfoxaflor. These results indicate that sublethal concentrations of sulfoxaflor inhibited the development and reproduction of A. citricola in both the exposed generation and the subsequent generation, leading to a suppression of population growth over two consecutive generations. This research provides a foundation for a deeper understanding of the intergenerational sublethal effects of sulfoxaflor and suggests that sulfoxaflor has promising potential for controlling A. citricola.

亚砜氟对柑桔蚜的跨代亚致死效应（半翅目：蚜科）

citricola Van der Goot是中国严重的果树害虫。亚砜虫胺是一种新型的亚砜亚胺类杀虫剂，已广泛用于防治吸虫。本研究旨在探讨亚砜氟对柑橘蚜生物学性状和代谢酶活性的跨代亚致死效应。结果表明，亚致死浓度（LC10和LC20）显著降低了F0代成虫寿命和繁殖力。此外，F1代一龄若虫和预成虫的发育时间也显著延长。F1代的总预繁殖期（TPRP）和平均世代时间(T)也显著延长。因此，F1代的繁殖力、内在增长率（rm）和有限增长率（λ）显著降低。此外，亚致死浓度的亚致死浓度的亚硫酸盐处理后，柠檬酸橙细胞色素P450单加氧酶（P450）和羧酸酯酶（CarE）活性增强，表明它们参与了亚硫酸盐的解毒作用。这些结果表明，亚致死浓度的亚砜对暴露代和后代的柠檬酸单胞螨的发育和繁殖都有抑制作用，导致连续两代的种群增长受到抑制。本研究为深入了解亚致死效应提供了基础，并提示亚致死效应在柑桔蚜防治中具有广阔的应用前景。

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.
