Analysis of the Evolutionary Relationship and Geographical Patterns of Genetically Varied Populations of Diamondback Moth, Plutella Xylostella (L.)
Analysis of the evolutionary relationship and geographical patterns of genetically varied populations of diamondback moth, Plutella xylostella (L.) by Shijun You MSc., The University of British Columbia, 2010 A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Botany) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) October 2017 © Shijun You, 2017 Abstract The diamondback moth (DBM), Plutella xylostella, is well known for its extensive adaptation and distribution, high level of genetic variation and polymorphism, and strong resistance to a broad range of synthetic insecticides. Although understanding of the P. xylostella biology and ecology has been considerably improved, knowledge on the genetic basis of these traits remains surprisingly limited. Based on data generated by different sets of molecular markers, we uncovered the history of evolutionary origin and regional dispersal, identified the patterns of genetic diversity and variation, characterized the demographic history, and revealed natural and human-aided factors that are potentially responsible for contemporary distribution of P. xylostella. These findings rewrite our understanding of this exceptional system, revealing that South America might be a potential origin of P. xylostella, and recently colonized across most parts of the world resulting possibly from intensified human activities. With the data from selected continents, we demonstrated signatures of localized selection associated with environmental adaptation and insecticide resistance of P. xylostella. This work brings us to a better understanding of the regional movement and genetic bases on rapid adaptation and development of agrochemical resistance, and provides a solid foundation for better monitoring and management of this worldwide herbivore and forecast of regional pest status of P. -
Is Diadegma Insulare Or Microplitis Plutellae a More Effective Parasitoid of the Diamondback Moth, Plutella Xylostella ?
War of the Wasps: Is Diadegma insulare or Microplitis plutellae a More Effective Parasitoid of the Diamondback Moth, Plutella xylostella ? ADAMO YOUNG 108 Homestead Street, Ottawa Ontario K2E 7N6 Canada; email: [email protected] Young, Adamo. 2013. War of the wasps: is Diadegma insulare or Microplitis plutellae a more effective parasitoid of the Dia - mondback Moth, Plutella xylostella ? Canadian Field-Naturalist 127(3): 211–215. Parasitism levels by Diadegma insulare (Muesebeck) (Hymenoptera: Ichneumonidae) and Microplitis plutellae (Haliday) (Hymenoptera: Braconidae) at various densities of their host, Plutella xylostella (L.) (Lepidoptera: Plutellidae), were assessed. Cages with densities of 10 hosts, 20 hosts, and 40 hosts were set up, with the cage volume (40 500 cm 3) and number of wasps (2 females) remaining constant. The host populations were also exposed to the wasps for two different exposure times: 1 day and 3 days. The study showed that D. insulare was a better parasitoid overall, achieving a level of parasitism equal to or higher than M. plutellae at all densities. Microplitis plutellae performed best at a lower host density (76% ± 9% of 10 hosts vs. 43% ± 3% of 40 hosts). Diadegma insulare performed similarly at all densities tested (75% ± 5% of 10 hosts, 83% ± 4% of 20 hosts, and 79% ± 6% of 40 hosts). This suggests that D. insulare may be the better parasitoid overall and should be applied in severe, large-scale infestations, while M. plutellae may be better for small-scale infestations. Key Words: Diamondback Moth; Plutella xylostella; Microplitis plutellae; Diadegma insulare; parasitoids; biological control Introduction ical control can provide better control than pesticides. -
Lepidoptera in Cheshire in 2002
Lepidoptera in Cheshire in 2002 A Report on the Micro-Moths, Butterflies and Macro-Moths of VC58 S.H. Hind, S. McWilliam, B.T. Shaw, S. Farrell and A. Wander Lancashire & Cheshire Entomological Society November 2003 1 1. Introduction Welcome to the 2002 report on lepidoptera in VC58 (Cheshire). This is the second report to appear in 2003 and follows on from the release of the 2001 version earlier this year. Hopefully we are now on course to return to an annual report, with the 2003 report planned for the middle of next year. Plans for the ‘Atlas of Lepidoptera in VC58’ continue apace. We had hoped to produce a further update to the Atlas but this report is already quite a large document. We will, therefore produce a supplementary report on the Pug Moths recorded in VC58 sometime in early 2004, hopefully in time to be sent out with the next newsletter. As usual, we have produced a combined report covering micro-moths, macro- moths and butterflies, rather than separate reports on all three groups. Doubtless observers will turn first to the group they are most interested in, but please take the time to read the other sections. Hopefully you will find something of interest. Many thanks to all recorders who have already submitted records for 2002. Without your efforts this report would not be possible. Please keep the records coming! This request also most definitely applies to recorders who have not sent in records for 2002 or even earlier. It is never too late to send in historic records as they will all be included within the above-mentioned Atlas when this is produced. -

We analyse patterns of variation among 532 P. xylostella genomes, representing a worldwide sample of 114 populations. We find evidence that suggests South America is the geographical area of origin of this species, challenging earlier hypotheses of an Old-World origin. -

Successful overwintering was not demonstrated at either site for any life stage under a variety of tillage and organic matter treatments, using either laboratory-reared or field-acclimated specimens of diamondback moth. Diamondback moth infestations in western Canada evidently originate primarily from southern U.S.A. or Mexico when strong winds carry adults northward in spring. To provide early warning predictions of infestations, air parcel trajectories into western Canada were investigated for monitoring long-range movement of P. xylostella early in the season. Using wind fields generated by the Canadian Meteorological Centre’s Global Environmental Multiscale model, three-dimensional air parcel trajectories were calculated using time-forward (prognostic) and time-backward (diagnostic) modes for several sites in North America. The model predicted strong northerly airflow in May 2001 which coincided with the occurrence of massive infestations of diamondback moth in canola in western Canada. -

Botolph's Bridge, Hythe Redoubt, Hythe Ranges West And
Folkestone and Hythe Birds Tetrad Guide: TR13 G (Botolph’s Bridge, Hythe Redoubt, Hythe Ranges West, and Nickolls Quarry) The tetrad TR13 G contains a number of major local hotspots, with Nickolls Quarry, the Botolph’s Bridge area and part of Hythe Ranges located within its boundaries. As a consequence the tetrad has the richest diversity of breeding birds in the local area, with 71 species having a status of at least possible in the latest BTO Atlas survey. It also had the highest total of species (125) in the winter Atlas survey. Sadly a major housing development is now in progress at the Nickolls Quarry site and much of the best habitat is now being disturbed or lost. Nickolls Quarry has been watched since the late 1940s, though early coverage was patchy, particularly in the 1960s and 1970s. As a working quarry the site has undergone significant changes during this time, expanding from two small pits to a much larger area of open water, some of which has since been backfilled. During 2001 to 2004 a series of shallow pools were created which proved particularly attractive to waders. Nickolls Quarry in 1952 Nickolls Quarry in 1998 Looking roughly northwards across the 'old pit' Looking south-west across the site towards the Hythe Roughs towards Dungeness Although a major housing development is underway on the site it still contains some interesting habitats. The lake is easily the largest area of open water in the local area and so remains one of the best areas for wildfowl, particularly during cold weather, for example in December 2010 when there were peak counts of 170 Wigeon, 107 Coot, 104 Pochard, 100 Teal, 53 Tufted Duck, 34 Gadwall, 18 Mute Swan, 12 Pintail, 10 Bewick’s Swan, 8 Shoveler, singles of Goldeneye and Goosander, and 300 White-fronted Geese flew over. -

November 2005 Genera Paraswammerdamia Friese and Eidophasia Stephens recorded in Israel (Lepidoptera: Yponomeutoidae, Plutellidae) Zlata GERSHENSON, Tomáš PAVLÍČEK & Eviatar NEVO Abstract: Two species of moths belonging to the families Yponomeutidae and Plutellidae were newly recorded in Israel: Paraswammerdamia conspersella (Tengström) and Eidophasia messingiella (Fischer v. Röeslerstamm). The first species was believed to be present in central and northern Europe only, whereas the second one is known also from Europe, the Caucasus, the Trans-Caucasus, and Asia Minor. Zusammenfassung: Zwei Schmetterlingsarten, die den Familien Ypono- meutidae und Plutellidae angehören, wurden erstmals in Israel festge- stellt: Paraswammerdamia conspersella (Tengström) und Eidophasia messingiella (Fischer v. Röeslerstamm). Von der ersten Art wurde ange- nommen, dass sie nur in Zentral- und Nord-Europa vorkomme, während die zweite auch von Europa, dem Kaukasus, dem Transkaukasus und Kleinasien bekannt ist. Key words: Lepidoptera, Yponomeutidae, Plutellidae, Paraswammer- damia , Eidophasia, Israel Introduction Yponomeutoid moths represent a worldwide distributed phyto- phagous group which occurs in very different landscapes such as forests, steppes, mountains, lowlands, deserts, and agricultural coenoses and which is trophically connected to 23 plant families (GERSHENSON & ULENBERG 1998). In spite of the ecological significance of this group, the fauna of the superfamily Yponomeutoidea of Israel has been insuf- ficiently known until recent time.
