Plant, Cell &Environment, EarlyView.ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...

Molecular mechanisms of Tetranychus urticae chemical adaptation in hop fields [PDF]
Scientific Reports, 2015 AbstractThe two-spotted spider mite,Tetranychus urticaeKoch is a major pest that feeds on >1,100 plant species. Many perennial crops including hop (Humulus lupulus) are routinely plagued byT. urticaeinfestations. Hop is a specialty crop in Pacific Northwest states, where 99% of all U.S. hops are produced. To suppressT.

Plant, Cell &Environment, EarlyView.ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Genome wide gene-expression analysis of facultative reproductive diapause in the two-spotted spider mite Tetranychus urticae [PDF]
, 2013 Background: Diapause or developmental arrest, is one of the major adaptations that allows mites and insects to survive unfavorable conditions. Diapause evokes a number of physiological, morphological and molecular modifications.

Plant, Cell &Environment, EarlyView.ABSTRACT Entomopathogenic nematodes (EPNs) are key biological control agents in agriculture, but their direct effects on plant metabolism and resistance to herbivory remain underexplored. By combining transcriptomic, metabolomic, and herbivore assays, this study aimed at providing a holistic description of maize root responses to EPNs and to assess ...

, 2017 Mortality of Tetranychus urticae caused by fenbutatin oxide The ratios of reduction (mortality ratios) of T. urticae were significantly different between sampling dates (F = 2.39; df = 19; P = 0.006) (Figure 2). One day after the first application, fenbutatin oxide produced 42.6 % reduction of T. urticae.

Emerging Viral Threats in Rice: A Decade of Discovery and Implications for Crop Protection
Plant, Cell &Environment, EarlyView.ABSTRACT Rice viral diseases pose severe threats to global food security, with over 20 viruses identified in China alone. The advent of high‐throughput sequencing has accelerated the discovery of novel viruses in cultivated and wild rice, unveiling previously undetected threats.
