“…Genotypic patterns did not support the hypothesis that founders of leaf galls were the products of sexual reproduction between root galling insects (Corrie et al, 2002). Instead, the patterns were consistent with the hypothesis that root populations largely reproduced by parthenogenesis.…”

“…To enable patterns of genotypic distribution to be examined on a microgeographic scale, the presence of multiple lineages of grape phylloxera at the study sites was required. Previous sampling revealed the presence of several (Z7) multilocus genotypes at each site (Corrie et al, 2002).…”

“…vitifoliae sample collection and microsatellite amplification Two vineyards, which exhibited leaf galls in the year prior to this study (Corrie et al, 2002), were examined for the presence of leaf galls during December-January 2001. Leaf galls were only observed at one site restricting the leaf galling experiment to a single vineyard located in Glenrowan in northeastern Victoria, Australia (designated as GR-1 block A).…”

“…Recently, four microsatellite markers were developed for grape phylloxera to investigate the incidence of sexual and asexual reproduction in commercial vineyards in Australia (Corrie et al, 2002). Genotypic patterns did not support the hypothesis that founders of leaf galls were the products of sexual reproduction between root galling insects (Corrie et al, 2002).…”

“…We tested if lineages are randomly distributed or if there is spatial structure within a block. Insects were collected from the roots of two vineyard blocks in which asexual lineages were known to be present (Corrie et al, 2002). Clone diversity was determined by microsatellite analysis, and a joincount spatial autocorrelation approach (Cliff and Ord, 1981;Epperson, 1993) was used to test for spatial patterns.…”

Patterns of variation at microsatellite loci suggest that root populations of the pest grape phylloxera (Daktulosphaira vitifoliae) are largely parthenogenetic in Australian vineyards. To investigate reproduction in leaf galling phylloxera and the association between these individuals and phylloxera on roots, we examined in detail genetic variation in phylloxera from a vineyard block. Some genotypes found on leaf galls within this block were not present on roots, whereas others spanned both zones. There was no evidence that genotypes on roots were the product of sexual reproduction in leaf galls. mtDNA variation was not associated with the location of the phylloxera clones. The spatial distribution of genotypes within a root population was further investigated by intensively sampling phylloxera from another vineyard block. Joincount spatial autocorrelation statistics were used to explore fine-scale spatial structure. Clones were nonrandomly distributed within the block and there was evidence that the distribution of clones followed rows. These findings suggest firstly that there is limited dispersal of root and leaf feeding phylloxera, and secondly that factors, other than vine host, are likely to be important and contribute to clonal structure within populations.

Cyclical Parthenogenesis and Viviparity in Aphids as Evolutionary Novelties

Evolutionary novelties represent challenges to biologists, particularly those who would like to understand the developmental and genetic changes responsible for their appearance. Most modern aphids possess two apparent evolutionary novelties: cyclical parthenogenesis (a life cycle with both sexual and asexual phases) and viviparity (internal development and live birth of progeny) in their asexual phase. Here I discuss the evolution of these apparent novelties from a developmental standpoint. Although a full understanding of the evolution of cyclical parthenogenesis and viviparity in aphids can seem a daunting task, these complex transitions can at least be broken down into a handful of steps. I argue that these should include the following: a differentiation of two developmentally distinct oocytes; de novo synthesis of centrosomes and modification of meiosis during asexual oogenesis; a loss or bypass of any cell cycle arrest and changes in key developmental events during viviparous oogenesis; and a change in how mothers specify the sexual vs. asexual fates of their progeny. Grappling with the nature of such steps and the order in which they occurred ought to increase our understanding and reduce the apparent novelty of complex evolutionary transitions.

Targeting surveillance strategies based on local-scale spatial heterogeneity can decrease the time to detection without increasing the survey cost, and surveillance that targets highly suitable soil is the most efficient strategy for detecting new incursions. In addition, combining targeted surveillance strategies with buffer zones and hygiene procedures, and updating surveillance strategies as additional species information becomes available, will further decrease the risk of pest spread. © 2018 Society of Chemical Industry.
