Motion to accept the Agenda: Wise/Harris CARRIED 3.0 Appointment of Resolutions Committee Hugh Philip volunteered to Chair. 4.0 Approval of 2003 Minutes Motion to accept the Minutes: Philip/Gavloski CARRIED 5.0 Business arising from 2003 minutes 5.1 Archiving of WCCP minutes Owen Olfert has compiled three complete sets of WCCP minutes from the inception of the meetings to date. One set will be stored at Agriculture and Agri-Food Canada, Saskatoon. The other two sets of minutes need to be stored elsewhere. After discussion it was decided that Scott Meers would arrange to have one set go to Alberta, archived at the University of Alberta or Alberta Agriculture, Food and Rural Development Edmonton office. Failing either of these two options, AAFC Lethbridge would be approached to be a repository. Owen Olfert will arrange to have the final set stored at the University of Saskatchewan Archives. 6.0 Provincial Insect Pest Summaries See Appendix Ia-d for reports from British Columbia, Alberta, Saskatchewan, and Manitoba. Following the Saskatchewan Provincial Entomologist’s Report is the Provincial Fruit Specialist’s Report on Pests of Fruits 2004, Appendix Ic.1. This report was not presented at the WCCP 1 meeting, but is included in the Minutes to provide a complete picture of pests of agriculture in Saskatchewan in 2004. Appointment of summarizers - to remain as for 2003. 7.0 Provincial Entomology Research Summaries See Appendix IIa-d for reports from British Columbia, Alberta, Saskatchewan, and Manitoba. Hugh Philip gave the BC report for Bob Vernon. Scott Meers gave the AB report for Hector Cárcamo. Chrystél Olivier has replaced M. Erlandson in Saskatchewan. 8.0 WCCP Guide - The question arose as to the handling of updates if the Guide is moved to the Western Forum website. Chapter editors will send changes to Section Editors, then to Ralph Lange (WF Webmaster). A definite date for yearly changes is necessary, although editors can make changes at any time. December 31 was decided as the deadline for Chapter changes to be posted on the Web. Therefore, Chapter editors must have their revisions in to the Section editors well before that date, preferably by the WCCP meeting. Motion by Olfert/Philip that we contact Ralph Lange to place the WCCP on the Western Forum website. CARRIED It is recommended that ‘Last Updated’ be added to the bottom of Chapters as they are edited, so that readers have an idea of the date of the information. 8.1 Appointment of Guide and section editors. See Appendix III for 2005 WCCP Chairs. Section editors to remain as J. Gavloski (Domestic), H. Philip (Horticulture), and I. Wise (Agriculture). 9.0 Canadian Food Inspection Agency Quarantine Update - Brian Rex See Appendix IV for the CFIA report from Brian Rex. 10.0 PMRA Report - Mike Fagan See Appendix V for the PMRA report from Mike Fagan 11.0 Ottawa research Centre Update - Peter Mason, read by Scott Hartley See Appendix VI for research report. 12.0 Sponsor Updates - Rod McLeod, Bayer Crop Life gave a presentation on Poncho and Prosper. Neil Wagner, Peacock Industries - gave handout on EcoBran grasshopper bait. Currently the company is working towards registration of the product for cutworm control. There was no representation from Crop Life Canada 13.0 Special reports - Appendix VII. 13.1 Wheat Stem Sawfly - Tom Shanower, USDA, Sidney, Montana. See Appendix VII.a. 13.2 Swede Midge - Rebecca Hallett, University of Guelph, Guelph, Ontario. See Appendix VII.b. 13.3 Update of West Nile Virus in Saskatchewan 2004 - Phil Curry, Sask. Health, Regina. See Appendix VII.c. 14.0 Election of 2005 WCCP Chair 2 Scott Meers, AAFRD elected Chair. Secretary to be appointed. 15.0 Resolutions None. However, because there was no response to last year’s resolution, the Committee decided to resubmit the resolution, this time to the federal Minister of Agriculture. See Appendix VIII. 16.0 Other business. Funds solicited by Western Forum - because neither WCCP nor WCPD is generating funds (the Guides, their chief form of income generation, are now available free on the Web), discussion occurred on possibly acquiring some of the funds solicited by WF to invite speakers to Committee meeting as well as to WF. One suggestion was that assets at the end of the meeting above $6500 be divided three ways for speaker costs. The Weed Science Society of Canada informally inquired about having a joint meeting with WF at some time, suggesting BC in 2006. According to the current rotation, Western Forum will be held in Manitoba in 2006. Date is also a problem, with weed meetings usually in early December. Although the two groups have some points of mutual interest, such as weed biocontrol and IPM that includes weeds, no ready solution for a joint meeting was found. 17.0 Adjournment 3 Appendix I - Provincial insect pest summaries Appendix Ia. British Columbia BRITISH COLUMBIA MINISTRY OF AGRICULTURE, FOOD & FISHERIES 2004 INSECT PEST REPORT to the WESTERN COMMITTEE ON CROP PESTS Compiled by: Hugh Philip, PAg Food Safety and Quality Branch BC Ministry of Agriculture, Food & Fisheries 200 -1690 Powick Road Kelowna, BC, V1X 7G5 [email protected] SUMMARY: 2004 followed the on-going trend of significant agricultural and horticultural insect pest problems in BC. Isolated infestations of grasshoppers required control on some rangeland from the Peace River region to southern BC. Alfalfa weevil infestations continue to require chemical control in the Southern Interior. Wireworms again caused injury to various row crops in the Fraser Valley and on Vancouver Island, and to forage corn in the Okanagan. Apple leaf midge is suspected to be present in the Okanagan Valley, likely arriving on infested soil from the Fraser Valley. Shothole borer infestations were once again a problem in many Okanagan Valley sweet cherry orchards late in the season. Climbing cutworms continue to cause damage to emerging buds on grape plants in many vineyards in the South Okanagan. An agromyzid leafminer attacking hellebore was detected for the first time in Canada. FORAGE CROPS Alfalfa weevil (Hypera postica) continues to be a problem in alfalfa crops in the Souhern Interior. Affected growers target larvae feeding on the regrowth following first cut. This on-going problem may be a result of growers harvesting first cut later than previously recommended. Delaying harvest may increase available regrowth upon which the larvae can feed, causing greater yield reduction and delaying crop development. Grasshoppers required control in several isolated areas from the Peace River region to southern BC, mainly on Crown rangeland and adjacent forage crops. The cooler, wetter August and September will hopefully have reduced grasshopper mating and egg-laying activity. HORTICULTURAL CROPS Shothole borer (Scolytus rugulosus): several reports of severe infestations again in sweet cherry blocks in August. Speculation is the trees suffered frost injury last fall or late this spring that may have impaired upward water movement during the hot weather in July and early August. This stress attracts wood borers. Maintaining healthy trees and sanitation (destruction of dead or dying branches and trees, wood piles) is the only way to minimize attack by these beetles and ambrosia beetles, another group of wood borers. 4 Apple leaf midge (Dasineura mali), first detected in the Fraser Valley in 1992, is possibly present in the Okanagan Valley. Pathway of introduction is unknown but one scenario is that some overwintering pupae entered the valley in soil on the roots of apple nursery stock grown in the Fraser Valley. The distribution is currently restricted to apple orchards adjacent to the Agriculture and Agri-Food Canada Pacific Agri- Food Research Centre (Summerland) where the midge’s presence went unreported in 2003. This insect poses a risk to apple nursery stock and young apple trees because it attacks the terminals leaves, reducing limb extension which is important in developing proper limb structure of young trees. Plans are underway to introduce a larval parasitoid from Europe released a few years ago in Nova Scotia where it has effectively controlled the midge. Wireworms continue to plaque potato, corn and other row crop producers in the Fraser Valley and on Vancouver Island. Crows have learned to pull up strawberry, corn and cole crop seedlings in search of wireworms, causing considerable crop loss in some cases. Similar damage occurred in the North Okanagan where seagulls, ravens and crows destroyed about 30% of a seedling silage corn crop. Growers are looking forward to Poncho-treated seed to protect next year’s young crops. Cherry bark tortrix (Enarmonia formosana) may not be present in the Salmon Arm area as reported in 2003. The moths collected on CBT pheromone-baited traps may be another species of Tortricidae associated with native sumac. This could explain why investigating AA-FC entomologists could not locate host trees infested with larvae. Further investigation is underway. Scientists suspect up to 7 species of climbing cutworms are responsible for damaging developing wine grape buds in the spring.

    HORTICULTURAL ENTOMOLOGY Influence of Plant Parameters on Occurrence and Abundance of Arthropods in Residential Turfgrass 1 S. V. JOSEPH AND S. K. BRAMAN Department of Entomology, College of Agricultural and Environmental Sciences, University of Georgia, 1109 Experiment Street, GrifÞn, GA 30223-1797 J. Econ. Entomol. 102(3): 1116Ð1122 (2009) ABSTRACT The effect of taxa [common Bermuda grass, Cynodon dactylon (L.); centipedegrass, Eremochloa ophiuroides Munro Hack; St. Augustinegrass, Stenotaphrum secundatum [Walt.] Kuntze; and zoysiagrass, Zoysia spp.], density, height, and weed density on abundance of natural enemies, and their potential prey were evaluated in residential turf. Total predatory Heteroptera were most abundant in St. Augustinegrass and zoysiagrass and included Anthocoridae, Lasiochilidae, Geocoridae, and Miridae. Anthocoridae and Lasiochilidae were most common in St. Augustinegrass, and their abundance correlated positively with species of Blissidae and Delphacidae. Chinch bugs were present in all turf taxa, but were 23Ð47 times more abundant in St. Augustinegrass. Anthocorids/lasiochilids were more numerous on taller grasses, as were Blissidae, Delphacidae, Cicadellidae, and Cercopidae. Geocoridae and Miridae were most common in zoysiagrass and were collected in higher numbers with increasing weed density. However, no predatory Heteroptera were affected by grass density. Other beneÞcial insects such as staphylinids and parasitic Hymenoptera were captured most often in St. Augustinegrass and zoysiagrass. These differences in abundance could be in response to primary or alternate prey, or reßect the inßuence of turf microenvironmental characteristics. In this study, SimpsonÕs diversity index for predatory Heteroptera showed the greatest diversity and evenness in centipedegrass, whereas the herbivores and detritivores were most diverse in St. Augustinegrass lawns. These results demonstrate the complex role of plant taxa in structuring arthropod communities in turf.

  • 197 Section 9 Sunflower (Helianthus
    SECTION 9 SUNFLOWER (HELIANTHUS ANNUUS L.) 1. Taxonomy of the Genus Helianthus, Natural Habitat and Origins of the Cultivated Sunflower A. Taxonomy of the genus Helianthus The sunflower belongs to the genus Helianthus in the Composite family (Asterales order), which includes species with very diverse morphologies (herbs, shrubs, lianas, etc.). The genus Helianthus belongs to the Heliantheae tribe. This includes approximately 50 species originating in North and Central America. The basis for the botanical classification of the genus Helianthus was proposed by Heiser et al. (1969) and refined subsequently using new phenological, cladistic and biosystematic methods, (Robinson, 1979; Anashchenko, 1974, 1979; Schilling and Heiser, 1981) or molecular markers (Sossey-Alaoui et al., 1998). This approach splits Helianthus into four sections: Helianthus, Agrestes, Ciliares and Atrorubens. This classification is set out in Table 1.18. Section Helianthus This section comprises 12 species, including H. annuus, the cultivated sunflower. These species, which are diploid (2n = 34), are interfertile and annual in almost all cases. For the majority, the natural distribution is central and western North America. They are generally well adapted to dry or even arid areas and sandy soils. The widespread H. annuus L. species includes (Heiser et al., 1969) plants cultivated for seed or fodder referred to as H. annuus var. macrocarpus (D.C), or cultivated for ornament (H. annuus subsp. annuus), and uncultivated wild and weedy plants (H. annuus subsp. lenticularis, H. annuus subsp. Texanus, etc.). Leaves of these species are usually alternate, ovoid and with a long petiole. Flower heads, or capitula, consist of tubular and ligulate florets, which may be deep purple, red or yellow.

The progressive restrictions in the matter of efficient synthetic chemicals for health and environmental care brought out the need for alternative management techniques. This paper summarizes the main potential tools that have been studied up to now and that could be applied together in integrated pest management systems and suggests guidelines for future research. Keywords: wireworms; click beetles; Agriotes; integrated pest management 1. Introduction Wireworms are the larvae of click beetles (Coleoptera: Elateridae). They consist of more than 9,000 species distributed worldwide, [1] and some are important pests of a wide variety of crops, such as potato, cereals, carrot, sugar beet, sugarcane and soft fruits (e.g., [2±6]). In Europe, damages due to wireworm infestation are mainly attributed to the genus Agriotes Eschscholtz, as witnessed by the numerous studies aiming at their management.

  • Inventory and Review of Quantitative Models for Spread of Plant Pests for Use in Pest Risk Assessment for the EU Territory1
    EFSA supporting publication 2015:EN-795 EXTERNAL SCIENTIFIC REPORT Inventory and review of quantitative models for spread of plant pests for use in pest risk assessment for the EU territory1 NERC Centre for Ecology and Hydrology 2 Maclean Building, Benson Lane, Crowmarsh Gifford, Wallingford, OX10 8BB, UK ABSTRACT This report considers the prospects for increasing the use of quantitative models for plant pest spread and dispersal in EFSA Plant Health risk assessments. The agreed major aims were to provide an overview of current modelling approaches and their strengths and weaknesses for risk assessment, and to develop and test a system for risk assessors to select appropriate models for application. First, we conducted an extensive literature review, based on protocols developed for systematic reviews. The review located 468 models for plant pest spread and dispersal and these were entered into a searchable and secure Electronic Model Inventory database. A cluster analysis on how these models were formulated allowed us to identify eight distinct major modelling strategies that were differentiated by the types of pests they were used for and the ways in which they were parameterised and analysed. These strategies varied in their strengths and weaknesses, meaning that no single approach was the most useful for all elements of risk assessment. Therefore we developed a Decision Support Scheme (DSS) to guide model selection. The DSS identifies the most appropriate strategies by weighing up the goals of risk assessment and constraints imposed by lack of data or expertise. Searching and filtering the Electronic Model Inventory then allows the assessor to locate specific models within those strategies that can be applied.
