Abstract

Parasitoids constantly evaluate their environment to optimise oviposition host utilisation based on their life history parameters and host characteristics, including density. Any factors impairing chemosensory perception, learning and memory of oviposition decisions negatively impact fitness. In the Anthropocene, stressors, for example, elevated temperatures, Wolbachia infection (likely modulated by temperature), pesticides, light pollution and water deficits in plants that provide resources for parasitoid hosts, impact parasitoid oviposition. Such physiological stressors often induce superparasitism since parasitoids are unable to remember prior oviposition on hosts or cause impaired offspring sex ratio. While the effect of these stressors on parasitoid oviposition has been examined individually, their combined effects remain unexplored. Since parasitoids are exposed to these stressors simultaneously, future work must examine their cumulative impact.

寄生虫在环境诱导的生理压力下的产卵决定。

寄生虫会根据其生活史参数和寄主特征（包括密度）不断评估环境，以优化对产卵寄主的利用。任何有损于化感感知、学习和记忆产卵决定的因素都会对适应能力产生负面影响。在人类世，温度升高、沃尔巴克氏体感染（可能受温度调节）、杀虫剂、光污染以及为寄生虫宿主提供资源的植物缺水等压力因素都会影响寄生虫的产卵。由于寄生虫无法记住先前在寄主身上的产卵情况，此类生理压力通常会诱发超寄生现象，或导致后代性别比例受损。虽然这些应激因素对寄生虫产卵的影响已被单独研究过，但它们的综合影响仍有待探索。由于寄生虫会同时受到这些应激因素的影响，因此未来的工作必须研究它们的累积影响。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
