A whole ecosystem approach to pear psyllid (Cacopsylla pyri) management in a changing climate

Journal of Pest Science, Journal Year: 2024, Volume and Issue: 97(3), P. 1203 - 1226

Published: April 2, 2024

Abstract Whole ecosystem-based approaches are becoming increasingly common in pest management within agricultural systems. These strategies consider all trophic levels and abiotic processes an ecosystem, including interactions between different factors. This review outlines a whole ecosystem approach to the integrated of pear psyllid ( Cacopsylla pyri Linnaeus) Pyrus communis L.) orchards, focusing on potential disruptions as result climate change. Pear is estimated cost UK industry £5 million per annum has significant economic impact production globally. Pesticide resistance well documented psyllids, leading many growers rely biological control using natural enemies during summer months. In addition, multiple insecticides commonly used have been withdrawn from Europe, emphasising need for alternative methods. There growing concern that change could alter phenological events agroecosystems. For example, warmer temperatures lead earlier flowering emergence, faster insect development rates altered activity levels. If impacts differently enemies, then mismatches occur, impacting populations. aims evaluate current C. management, discuss this agroecosystem highlight changes top-down bottom-up provides recommended identifies evidence gaps areas future research.

Volatile communication in Actinobacteria: a language for secondary metabolism regulation

Microbial Cell Factories, Journal Year: 2024, Volume and Issue: 23(1)

Published: June 18, 2024

Abstract Background Volatile compounds are key elements in the interaction and communication between organisms at both interspecific intraspecific levels. In complex bacterial communities, emission of these fast-acting chemical messengers allows an exchange information even a certain distance that can cause different types responses receiving organisms. The changes secondary metabolism as consequence this arouse great interest field searching for bioactive since they be used tool to activate silenced metabolic pathways. Regarding potential Actinobacteria group presents production with attractive properties, we evaluated reply emitted volatile generate other individuals same group. Results We recently reported released by streptomycete species trigger modulation biosynthetic gene clusters Streptomyces spp. which finally leads activation/repression metabolites recipient strains. Here present application rationale broader community evaluate volatiles signaling effectors drive activation biosynthesis members Using cocultures actinobacteria (where only reach strain) were able modify drives overproduction (e.g., granaticins, actiphenol, chromomycins) and/or de novo collismycins, skyllamycins, cosmomycins) belonging important biological activities. Conclusions This work shows how vary significantly when exposed co-culture phylum-shared bacteria, effects being variable depending on strains culture media. approach applied new drug discovery increase battery produced bacteria potentially treatments humans animals.

Biogenic secondary organic aerosol participates in plant interactions and herbivory defense

Science, Journal Year: 2024, Volume and Issue: 385(6714), P. 1225 - 1230

Published: Sept. 12, 2024

Biogenic secondary organic aerosols (SOAs) can be formed from the oxidation of plant volatiles in atmosphere. Herbivore-induced (HIPVs) elicit defenses, but whether such ecological functions persist after they form SOAs was previously unknown. Here we show that Scots pine seedlings damaged by large weevils feeding on their roots release HIPVs trigger defenses neighboring conspecific plants. The biological activity persisted had been oxidized to SOAs, which indicated receivers displaying enhanced photosynthesis, primed volatile and reduced weevil damage. elemental composition quantity likely determines functions. This work demonstrates plant-derived mediate interactions between plants, highlighting significance ecosystems.
