Abstract

This review focuses on biological control interactions in arid areas and is motivated by the need to devise sustainable agricultural practices for a warming and drying world. Parasitoids, important natural enemies of crop pests, are diverse and abundant in natural arid habitats. Dryland croplands, which are usually irrigated, are also rich in local parasitoids. Nevertheless, biological control projects in arid croplands mostly involve imported parasitoids (classical biological control) rather than the conservation of native species. Dryland parasitoids experience heat, drought, low relative humidity, sparse vegetation, and low host densities. Heat resistance combines local genetic adaptations, behavioral and physiological flexibility, and microbial symbioses, but how parasitoids cope with other aridity-related challenges is insufficiently understood. How dryland conditions impact host–parasitoid population dynamics also requires further study.

旱地农业生态系统中用于生物防治的寄生虫。

这篇综述的重点是干旱地区的生物防治相互作用，其动机是需要为气候变暖和干旱的世界制定可持续的农业措施。寄生虫是农作物害虫的重要天敌，在自然干旱生境中种类繁多，数量巨大。通常进行灌溉的旱地农田也有丰富的本地寄生虫。然而，干旱农田的生物防治项目大多涉及进口寄生虫（传统生物防治），而不是保护本地物种。旱地寄生虫经历过高温、干旱、相对湿度低、植被稀疏和寄主密度低的环境。抗热性结合了当地的遗传适应性、行为和生理灵活性以及微生物共生，但寄生虫如何应对其他与干旱有关的挑战还没有得到充分了解。旱地条件如何影响寄主-寄生虫种群动态也需要进一步研究。

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.
