“…Arthropod vectors are not considered important factors [although, interestingly, mite associations with some Fusarium species have been reported (e.g. Kemp et al, 1996)]. In the case of FHB, different epidemic roles for different crop species mean that cropping systems influence disease risk, as one host species can provide a 'green bridge' when other host species are not available for the pathogen.…”

Complexity in climate‐change impacts: an analytical framework for effects mediated by plant disease

et al. 2011

The impacts of climate change on ecosystem services are complex in the sense that effective prediction requires consideration of a wide range of factors. Useful analysis of climate-change impacts on crops and native plant systems will often require consideration of the wide array of other biota that interact with plants, including plant diseases, animal herbivores, and weeds. We present a framework for analysis of complexity in climate-change effects mediated by plant disease. This framework can support evaluation of the level of model complexity likely to be required for analysing climate-change impacts mediated by disease. Our analysis incorporates consideration of the following set of questions for a particular host, pathogen, host-pathogen combination, or geographic region. 1. Are multiple biological interactions important? 2. Are there environmental thresholds for population responses? 3. Are there indirect effects of global change factors on disease development? 4. Are spatial components of epidemic processes affected by climate? 5. Are there feedback loops for management? 6. Are networks for intervention technologies slower than epidemic networks? 7. Are there effects of plant disease on multiple ecosystem services? 8. Are there feedback loops from plant disease to climate change? Evaluation of these questions will help in gauging system complexity, as illustrated for fusarium head blight and potato late blight. In practice, it may be necessary to expand models to include more components, identify those components that are the most important, and synthesize such models to include the optimal level of complexity for planning and research prioritization.

“…The involvement of arthropods in the dispersal of inoculum in small‐grained cereal crops and maize has been proposed previously (Parry et al ., ; Munkvold, ), although the exact role played by arthropods in fusarium disease epidemiology is not well understood and has only been studied in a limited number of species‐specific situations. For example, there are documented cases where insects and mites have been observed to transmit Fusarium inoculum between host plants (Kemp et al ., ; Sobek & Munkvold, ), and where the activity of pests has been correlated with infection by Fusarium spp. (Mongrain et al ., ; Saladini et al ., ).…”

“…Microscopic examination of S. avenae feeding on F. poae cultures revealed the presence of sporothecae containing microsporidia of the fungus. This close association between the mite and fungus is considered responsible for causing Fusarium glume spot on wheat in South Africa (Kemp et al 1996).…”

The role of eriophyoids in fungal pathogen epidemiology, mere association or true interaction?

et al. 2009

A considerable number of plant feeding mites representing different families such as Acaridae, Siteroptidae, Tydeidae, and Tarsonemidae interact with plant pathogenic fungi. While species within the Eriophyoidea appear to be the most common phytophagous mites vectoring virus diseases, little is known of their role in fungal pathogen epidemiology. In the present article, we present two studies on eriophyoid-fungal relationships. The first focusing on the association between Aceria mangiferae and the fungal pathogen Fusarium mangiferae in mango is presented as a case study. The second, as the research is still in a preliminary phase, reports on quantitative and descriptive associations between the cereal rust mite Abacarus hystrix and rusts caused by Puccinia spp. Mango bud tissue colonized with F. mangiferae, and wheat and quackgrass leaves colonized with Puccinia spp., supported significantly higher populations of eriophyoid mites. Both mite species were observed bearing the spores of the respective pathogens on their body integument. Aceria mangiferae vectored the pathogen's spores into the bud, the sole port of entry for the fungal pathogen and the frequency and severity of fungal infection increased in the presence of A. mangiferae. While it appears that eriophyoids are playing a role in fungal epidemiology, clearly further research is needed to enhance our understanding of direct and indirect (plant mediated) interactions between plant pathogens and eriophyoid mites in different plant-pathogen systems.
