Insects as alternative hosts for phytopathogenic bacteria [PDF]

open access: yesFEMS Microbiology Reviews, 2011
Phytopathogens have evolved specialized pathogenicity determinants that enable them to colonize their specific plant hosts and cause disease, but their intimate associations with plants also predispose them to frequent encounters with herbivorous insects, providing these phytopathogens with ample opportunity to colonize and eventually evolve ...

Alternative Host Model To Evaluate Aeromonas Virulence [PDF]

open access: yesApplied and Environmental Microbiology, 2007
ABSTRACT Bacterial virulence can only be assessed by confronting bacteria with a host. Here, we present a new simple assay to evaluate Aeromonas virulence, making use of Dictyostelium amoebae as an alternative host model.

New Records of Leaf-Feeding for Adult \u3ci\u3eDiabrotica Barberi\u3c/i\u3e (Coleoptera: Chrysomelidae) [PDF]

open access: yes, 2017
The first records of leaf-feeding on Iva xanthifolia (marsh elder) and Helianthus annuus (common sunflower) by adult Diabrotica barberi are reyorted. During September 1992, beetles were observed feeding on leaves 0 these plants, despite the availability ...

Identification of three Berberis species as potential alternate hosts for Puccinia striiformis f. sp. tritici in wheat-growing regions of Xinjiang, China

open access: yesJournal of Integrative Agriculture, 2019
Since the recent discovery of barberry (Berberis spp.) as an alternate host for the stripe rust pathogen Puccinia striiformis, many Chinese Berberis species have been identified as alternate hosts for P. striiformis f. sp. tritici.

Host Plant Suitability and a Test of the Feeding Specialization Hypothesis Using \u3ci\u3ePapilio Cresphontes\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

open access: yes, 2017
The concept that host plant favorites would be used for more rapid and/or efficient growth of the locally adapted individuals was tested in a preliminary way using the giant swallowtail butterfly, Papilio cresphontes.
