Manyof the members, however, got together on Thursday eveming, in various parts of the city ,notably in the homes of Dr~ B. Hocking and Dr. G. E. Ball; aild, after an executive meeting, in the suite of the President, Mr. J. W. Edmunds. The attendance at the 1961 meeting was excellent. A total of fifty-three memberswere registered and of this number five came from Sa.skatoon. It was most gratifying that these memberscame to the meeting from another province and it is hoped that they will continue to do so. Twenty-eight papers were sub~itted for the meeting following a trend that has developed in recent years of an increasing participation by the membersresult ing in a program of papers which were short and to the point and which covered a variety of subjects. This type of program appeared to be enjoyed by all since the problem of keeping to the scheduled times was minimized with the presentation o£ papers o£ £rom ten to fif'teen minutes length and attention never had a chance to lag •. The Minual Banquet was held on Friday evening and this was followed by a most interesting account of a trip made downthe entire length of Africa by Dr. B. Hocking. Slides were shown of vartous su.bjects from localities including the Upper Nile, Tanganyika, !anwibar, Victoria Falls and Capetown•• Tape recordings of the tribal music of the inhabitants of western Tanganyika were also heard by the membersin a;.ddition to a commentaryby Dr. Hocking on the types of instruments used.• AUI in all, it was a very enjoyable evening •• On Saturday morning the Annual Insect Collection Competition judging took place. A number of new entrants were noted this year and some of' the collections were extremely good. The prize winners are noted on a later page. 2 PRESIDENTIAL ADDRESS This has been a very, very busy year. I say this without any hesitancy. Perhaps not for this organization as an organization, but one 'bas no hesitancy in suggesting for the organization's members, it has been a busy year. kriyone (exc'eptir.ig a few) not busy in'this age is either too young, too old, ill, unimaginative, or lazy. A few and T stress a few are intelligent enough or strong enough to limit themselves to the things that need doing. I make few apologies for the inactivity of our organization this past· year. Wehave left undone somethings that should have beelldone. I am certain by the end of this meetil'lg we will be amazed at now muchhas been accorrplished by the membersof this fraternity. Before continuing fUrther, I would like to welCOmethe Saskatchewan visitors, new COmersto our organi7lation and Dr. Hocking, who has just returned from a year's absence. I am sure that we as aspiring scientists must take time out periodicalIy- to assess the objectives and motiveS behind our activities. It is interesting to note that to get an accurate compass reading, one must starid still. Having a compass is no assurance one is not lost. Few of us are presently doing what we intended to do. Wehave been sidetracked by unforeseen problems cropping up, by unexpected opening or closing of doors, so that nOWwe may find ourselves going at varying angles to the original course we charted. let me stress this is not necessarily good or bad. Of 'one thing I am certain, it is relevant that we kilowour present position,!) and that we have a course planned for our work. I should like at this time to review, renew or state a few facts. 1. We like to think of ourselves as scientists. As such our obligations are to attempt to transfer items from the field of theory, philosophy or unknownto the field of fact to discover new theories or philosophies. 2. We require, tb be usefuls inquisitive" imaginative minds. W'emust train ourselves to constantly wonder (hence you are excused if you ' appear to be in a daze, unless the reason goes back to John Barleycorn)., to ask continuous ly "why,\lwhy,\lwhy~or in Indian Language "Howa". 3. I am not so naive to think we can go on forever asking why or how• without getting a few ideas or theories. This is good. 4. The scientist w111 allow himself to think and work, far into the night or early morning (for which he will get no overtime - he may collect some rewarding criticism from his wife or family). Ii. scientist cannot turn off his ability to wonder. 3 5. IJs I said earlier ~ we must attempt to transfer our thinking, our theories into facts. 6. One of the highest tributes which can be made to a manis that he is an honest recorder of facts. 7. Honesty and integrity and very high morals are absolutely essential, if we are to be classed with the scientists who are worth remembering. 4 ~STRACTSOFPAPERS PRESENTED Biology of the sugar beet root maggot9 Tetanops myopaeformis (R8der) (Diptera$ Ortalidae) lA.

[Chenopodiaceae]) fields in southern Idaho; this contrasts with the approximately equal sex ratio typically observed within fields. Peak observation of mating pairs coincided with peak diurnal abundance of flies. Volatiles released by individual male and female flies were sampled from 08:00 to 24:00 hours in the laboratory using solid-phase microextraction and analyzed using gas chromatog- raphy/mass spectrometry (GC/MS). Eleven compounds were uniquely detected from males.

  • Abstract Wallace, Charles Reid. A
    ABSTRACT WALLACE, CHARLES REID. A Molecular and Morphological Analysis of Ulidiidae (Diptera: Tephritoidea). (Under the direction of Brian M. Wiegmann). Ulidiidae (Diptera: Tephritoidea) is a relatively small family of true flies, called the “picture-winged flies” for their patterned wings. Its relationship to the other members of Tephritoidea, and its monophyly, has been well established, through both morphological and molecular analysis. Its subfamilial relationships, however, have received limited molecular analysis, having had a significant cross-section of the family’s taxa represented in only two molecular studies (Galinskaya et al. 2014, Han and Ro 2016). The most contemporary treatment of the classification of the family is by Kamenev and Korneyev (2006), according to which the Ulidiidae is divided into two subfamilies (Otitinae, Ulidiinae), each of which is further delineated into tribes (Cephaliini, Myennidini, Otitini; Lipsanini, Pterocallini, Seiopterini, Ulidiini, respectively), with an additional incertae sedis group of genera within the Otitinae. These classifications are based solely on morphological analysis, and there remain multiple outstanding questions of the placement and monophyly regarding the tribes or several large, diverse, or enigmatic genera. Here, using the next-generation sequencing method of anchored hybrid enrichment, I investigate the phylogeny of Ulidiidae with particular attention paid to the constituency and monophyly of hypothesized tribes, monophyly of the two sub-families, and placement of genera. Through maximum likelihood analysis, my results establish strong support for the separation of Ulidiidae into two monophyletic subfamilies, but challenges the assignment of Myennidini to the Ulidiidae, and potentially of Seiopterini to the Ulidiinae. It additionally suggests the paraphyly of the tribe Pterocallini with respect to both Myennidini and Lipsanini, but supports the monophyly of all other tribes.

Central Avenue, Sidney, MT 59270 and 4Plant Sciences Department, North Dakota State University, Fargo, ND 58108 Abstract: The sugarbeet root maggot, Tetanops myopaeformis (Röder), is a major insect pest of sugarbeet, Beta vulgaris L., in North Dakota, Minnesota, and Idaho. Three biocontrol field trials using the insect pathogen Metarhizium anisopliae (Metch.) Sorok. ATCC 62176 in conjunction with cover crops were conducted in 2002-2004. Granular and aqueous spray formulations of M. anisopliae were applied in furrow to replicated plots at 8 x 1012 viable conidia/ha. Oat (Avena sativa L.) and rye (Secale cereale L.) cover crops were planted prior to sugarbeet at three rates to create different microenvironments for the fungus. Soil samples were collected at 0, 30, or 60 d after treatment (DAT). Significantly higher numbers of conidia were detected in soil samples collected immediately after application in fungus spray plots compared to granule plots. This suggested delayed activation and proliferation of M. anisopliae conidia on granules, which has also been observed in the laboratory. Soil sampling and dilution plating results indicated a 90% decline in conidial viability for the aqueous formulation within 30 DAT. In 2002, a 1.5 to 7.7-fold increase in conidial density per gram of soil occurred between 0 and 60 DAT in plots treated with M.

  • Sugar Beet Root Maggot: Identification, Biology, and Management*
    BUL 942 Sugar Beet Root Maggot: Identification, Biology, and Management* Erik J. Wenninger Tucker B. Daley Oliver T. Neher Edward J. Bechinski Contents 1 Introduction 2 Pest Description 3 Life Cycle 4 Host Plants and Damage 5 Designing an IPM Program Introduction 9 Additional Reading THE SUGAR BEET ROOT MAGGOT, Tetanops myopaeformis 9 About the Authors (von Röder), occurs wherever sugar beet is grown in Idaho. It is native to North America but did not become a serious pest in Idaho until the 1960s. Infestations historically have been the most damaging in Minidoka and Cassia Counties. However, localized infestations also may occur around Filer in Twin Falls County, near Notus and the Dry Lake area of Canyon County, and near American Falls in Power County. Infestations seldom reach damaging levels in other areas. This publication will help you to design an integrated pest management (IPM) program for the sugar beet root maggot. The IPM approach combines cultural controls with field scouting and thresholds to ensure that insecticide controls are used only when needed. Beet growers who use IPM can increase profits while reducing potential harmful effects associated with pesticides. *Modified from a previous publication written by Bechinski et al. (1994). Pest Description Sugar beet root maggots develop through four life stages: egg, larva, pupa, and adult. • Eggs are white, slightly curved, and about 1/25-in (1-mm) long (Figure 1). • Larvae are whitish legless maggots without distinct heads. The body grows to 1/3-in (8-mm) long, tapering to a cone at the head (Figure 2). • Pupae are brown with a hard-shelled capsule and are slightly smaller than full-grown larvae (Figure 3).

  • Screening for Resistance Against the Sugarbeet Root Maggot, Tetanops Myopaeformis (Diptera: Ulidiidae), Using a Greenhouse Bioassay
    Journal of Insect Science, (2018) 18(3): 11; 1–8 doi: 10.1093/jisesa/iey051 Research Screening for Resistance Against the Sugarbeet Root Maggot, Tetanops myopaeformis (Diptera: Ulidiidae), Using a Greenhouse Bioassay Tucker B. Daley and Erik J. Wenninger1 Department of Entomology, Plant Pathology, and Nematology, University of Idaho, Kimberly Research & Extension Center, Kimberly, ID 83341, and 1Corresponding author, e-mail: [email protected] Subject Editor: Junwei (Jerry) Zhu Received 7 March 2018; Editorial decision 7 May 2018 Abstract The sugarbeet root maggot, Tetanops myopaeformis (von Röder) (Diptera: Ulidiidae), is a major pest of sugar beet Beta vulgaris L. (Carophyllales: Amaranthaceae)in the United States and Canada. Larval feeding on roots can reduce both stand and yield. Current management practices are heavily reliant on chemical control. However, the carbamate and organophosphate insecticides that are commonly used against T. myopaeformis are being phased out of use. Host plant resistance against this pest shows promise, but difficulties with maintainingT. myopaeformis in culture have largely limited such studies to the field. A primary objective of this study was to develop protocols for rearing a laboratory colony of T. myopaeformis that would expedite assays aimed at screening for host plant resistance. Third (final) instar larvae were collected from the field and reared to the adult stage. These laboratory-reared adults laid eggs and ultimately produced a second generation of third-instar larvae in the lab. Adult flies reared from field-collected larvae were used to examine the modality of resistance of a known resistant variety by performing no-choice and paired-choice experiments alongside a susceptible variety in the greenhouse.

    The Effect of Aldicarb on Sugarbeet Insects and Yield U.S. Departme'rit of Agriculture Agricultural Research Service Agricultural Research Results•ARR-W-231July1982 ABSTRACT Approximately 450 species of insects were collected in sugarbeet fields in south-central Idaho over the 4-year period 1974 to 1977. Fifty-four species or species groups were taken from 50 percent or more of the fields sampled; 18 were classed as destructive or poten- tially destructive, 14 as beneficial, and 22 of unknown function. Of the 54, 18 were collected more commonly by sweep net, 34 were collected more commonly by pitfall traps, and 2 were collected equally by the two methods. Fourteen of the 54 were taken exclusively by pitfall traps. The apparent effect of aldicarb on insect populations varied widely with an overall reduction of about 20 percent. The effect of aldicarb treatment an the sugarbeet root maggot, curly top disease, lygus, and leaf miners in relation to plant stand and yield is pre- sented.

C. Blickenstaff INTRODUCTION In the United States, no systematic survey of the insects present in sugarbeet fields has been previously reported, and there are no reports on the effects of insecticide applications on beneficial insects. Data regarding economic threshold levels for the more commonly encountered destructive insects are also sparse. The frequency of occurrence and relative abundance of both de- structive and beneficial insects are of importance to the development of an integrated pest management program.
