Overview: biotic signalling for smart pest management

摘要

Biotic signalling refers to species or phylogenetic-clade-specific signals that elicit adaptive and acceptable responses within and among organisms. It is not only the molecular basis of the ecological relationships among different species, such as parasitism, symbiosis and predation, but also serves as ideal targets that can be used to manipulate these ecological relationships. This concept was proposed by a group of scientists from the Chinese Academy of Sciences (CAS) and actively pursued in a five-year research project in 2014 funded by the CAS ($40 million), entitled 'Decoding biotic interactions and mechanism for target management of agricultural pests'. The multidisciplinary project aimed at a systematic investigation of the intra-species and inter-species and interactions via biotic signalling, with the ultimate goal being the development of novel methods to manage the pest insects and diseases. We hereby propose a topic 'Biotic signalling sheds light on smart pest control' as a theme issue for the Philosophical Transactions of the Royal Society B. It contains a total of 18 reviews and research articles under the topic of signalling manipulation for pest management. Unravelling these complex interactions among plants, microbial pathogens and insects holds promise for developing novel strategies to protect crop plants without compromising agricultural productivity and environmental health.
