中文摘要:
植物与植食性昆虫、植食性昆虫与昆虫杆状病毒之间的两营养级互作关系,至今已有超过半个世纪的研究历史,但这三营养级的互作研究,在近20年才引起科学家的兴趣。在查阅并理解国内外相关文献的基础上,本文主要从植物的物理性状、营养物质和次生代谢物质三个角度出发,剖析植物调控昆虫响应病毒感染的生态生理及免疫机制,阐明植物影响病毒增殖、病毒组分及其感染过程和致病力的机理。此外,本文就植物、植食性昆虫和昆虫杆状病毒互作的研究方向、研究方法,进行了初步展望,以期为更好研究多营养级共存系统的食物网关系,提供理论依据。
英文摘要:
Although bi-trophic interactions between host plants and herbivorous insects, and
between herbivorous insects and baculoviruses, have been studied for more than
half a century, tri-trophic interactions have only attracted interest in the
last two decades. Based on reviews of both domestic and foreign literature, we
here describe the eco-physiological and immune mechanisms that insects use to respond
to baculovirus infection, and elucidate the mechanisms that plants use to
resist the pathogenicity of baculoviruses carried by host insects. We mainly
focus on three aspects: plant physical characteristics, nutrient metabolites
and secondary metabolites. Finally, we take a rough glance at the future of
direction of research, and the kinds of tri-trophic interactions between
plants, herbivorous insects and baculoviruses, in order to provide a
theoretical basis for understanding the co-existence of multi-trophic groups in
the food web.
