“…In addition, SoMV has been reported to be transmitted by the onion thrips Thrips tabaci [ 27 ]. A bird cherry-oat aphid Rhopalosiphum padi has been identified as the vector of CnMoV in New Zealand, where no beetle vector has been recorded [ 28 ]. A blueberry aphid Illinoia pepperi is the only known vector of Blueberry shoestring virus (BSSV) [ 29 ].…”

The genus Sobemovirus, unassigned to any family, consists of viruses with single-stranded plus-oriented single-component RNA genomes and small icosahedral particles. Currently, 14 species within the genus have been recognized by the International Committee on Taxonomy of Viruses (ICTV) but several new species are to be recognized in the near future. Sobemovirus genomes are compact with a conserved structure of open reading frames and with short untranslated regions. Several sobemoviruses are important pathogens. Moreover, over the last decade sobemoviruses have become important model systems to study plant virus evolution. In the current review we give an overview of the structure and expression of sobemovirus genomes, processing and functions of individual proteins, particle structure, pathology and phylogenesis of sobemoviruses as well as of satellite RNAs present together with these viruses. Based on a phylogenetic analysis we propose that a new family Sobemoviridae should be recognized including the genera Sobemovirus and Polemovirus. Finally, we outline the future perspectives and needs for the research focusing on sobemoviruses.

“…For example, in a pasture species trial, King et al (1982) found that black beetle decreased the ryegrass component and white fringed weevil (Graphognathus leucoloma) reduced clover yield. Another example of this type of biotic interaction is that the stress response by plants to root loss can improve food quality for aboveground pests like aphids (Masters et al 1993), which in turn are vectors of plant viruses (e.g., Mohamed 1978). However, in some situations, damage by one pest may render plants an unsuitable food resource for another.…”

New Zealand pastures are host to a range of native and exotic invertebrates. Many of these are pests that feed on the sown plant species, often causing plant death and deterioration in the productivity and persistence of the sward. While most research has focused on pest biology and control, studies of plant productivity show dramatic acute (short-medium term) and chronic (longterm) effects. For example, grass grub has been reported to cause 50% losses to ryegrass swards and Argentine stem weevil can cause a 20% loss of productivity, but the long term effects through loss of the sown species and changes in composition can be even more severe. Insect damage can be exacerbated by other biotic (e.g. weed invasion, grazing animals, plant pathogens) or abiotic factors (e.g. climate, soil fertility) to further reduce plant persistence. Some biotic and abiotic factors may interact with insect pests to have positive effects on pasture persistence, e.g. biocontrol agents that reduce pest density or addition of fertiliser to enable plants to recover from insect damage. For many pasture pests, knowledge of their ecology is based on research from over 20 years ago that, while still valid, needs to be updated to account for modern intensive pasture management practices, such as intensive grazing with a lack of reseeding, and new cultivars. To improve pasture persistence, integrated research programmes are needed that examine the relative importance of all factors contributing to plant survival and develop strategies to mitigate their effects. Keywords: Argentine stem weevil, black beetle, clover root weevil, drought, grass grub, grazing pressure, manuka beetle, nematodes, pasture persistence, pasture quality, pasture yield, porina, soil fertility, striped chafer.

“…There is little information available regarding the length of time the virus has been present in New Zealand. A comprehensive nationwide survey in 1976 found no evidence of RgMV infection, suggesting that RgMV has probably become established within the last 2 decades (Mohamed 1978).…”

Ryegrass mosaic virus (RgMV) is a mite-transmitted member of the Potyviridae that can seriously affect yield and persistence of ryegrass in pastures. To determine the incidence and distribution of RgMV in New Zealand, perennial ryegrass pastures were surveyed by indirect ELISA. RgMV was detected in all seven mature ( 4 years) North Island pastures and 60% of 20 mature South Island pastures, indicating that RgMV is established throughout New Zealand. A reverse transcriptasepolymerase chain reaction (RT-PCR) assay was developed to confirm the identity of RgMV. This assay was 200 times more sensitive than the indirect ELISA. A possible correlation between numbers of the eriophyid mites and the incidence of RgMV was observed in South Island pastures. Our results suggest that mite transmission may be more significant than ryegrass cultivar, pasture age, endophyte infection, or mechanical transmission in defining the incidence and distribution of RgMV. Options for the control of RgMV in New Zealand pastures are discussed.
