Western Forum for Pest Management Meeting 2016 Western Committee on Crop Pests Date: October 20, 2016 Location: Wanuskewin Heritage Park, Saskatoon, SK, Canada Chair: Scott Hartley Secretary: Meghan Vankosky 1. Meeting called to order by the Chair at 8:20 am; all attendees welcomed to the meeting. -approximately 35-45 in attendance; all attendees present at the beginning of the meeting introduced themselves 2. Chair outlined agenda for the meeting; no changes or discussion of agenda. 3. Minutes from 2015 meeting in Abbotsford, BC briefly summarized. No comments or additions made to 2015 minutes. 4. No new business arose from 2015 meeting. 5. Resolutions from 2015 meeting discussed, with no outstanding Resolutions identified. John Gavloski and Owen Olfert volunteered for 2016 Resolutions Committee. 6. Insect Pest Summaries Saskatchewan: Presented by Scott Hartley; report appended. Report concluded at 8:45. Questions: i. Q: Are survey results available on SaskAg website? A: Most maps will be available online in January 2017, PLW map already published. Alberta: Presented by Scott Meers with pictures by Shelley Barkley; report appended. Report concluded at 9:17 Questions: i. What was the incidence of wheat curl mite and wheat streak mosaic. A: ‘Big’ year for those in AB, also widespread in MB (input from John Gavloski) ii. What were tent caterpillar populations like? It was a big year in SK, were outbreaks observed in AB? A: Some activity, with a more significant pocket in Peace Region. Manitoba: Report presented by John Gavloski; report appended. Report concluded at 10:02. Questions: i. Were there flax and hemp surveys in 2016? A: John was called out to look at flax and hemp crops for different issues, but never found any of the insects of concern in the fields; did find natural enemies; no formal survey of those crops was conducted. ii. How much wheat midge resistant wheat is planted in MB? A: Less than 5%; uptake has not been great because midge populations are so low and there have been no bad years. iii. Have you observed Lygus movement from alfalfa to canola when alfalfa is cut? A: Have observed quick build-up of Lygus populations in canola in July that seems to coincide with drying cereals and some alfalfa being cut, but not sure that is the source. British Columbia: Report presented by Susanna Acheampong; report appended. Report concluded at 10:58. Questions: Scott Meers commented that it was unusual, suspect, that many pheromone traps were not as efficient for monitoring purposes this year as in the past, and that all provinces experienced some issues, albeit with different pest targets; Scott suggested this might be something to look into going forward. Summarizers for 2017 will be the same as in 2016. 7. Provincial Entomology Research Summaries for 2016 Saskatchewan: Report of 10 research projects and one research program under establishment summarized by Tyler Wist with input from SK researchers in attendance (Owen Olfert, Meghan Vankosky, Boyd Mori). -Erl Svendsen briefly discussed the AAFC Field Guide that is now available in hard copy and electronically; the guide will be updated as needed; four new insects have been added in 2016: brown marmorated stink bug, pea weevil, sugar beet root aphid and the bronzed blossom pollen beetle Alberta: Report of 23 research projects presented by Hector Carcamo with input from Jennifer Otani on projects in the Alberta Peace Region.

The international trade name for the product is Inscalis and a joint submission for registration has been made by Canada, USA, Mexico, and Australia; expect at least 3 years before product will be available for use in Canada BASF also undergoing nematode production and testing in Ontario and is working on a new strain of Beauveria that has been submitted to the EPA for mite control in addition to other insects already targeted by Beauveria products. 9. Special Reports Todd Kabaluk, AAFC Agassiz: “Toward a comprehensive approach to wireworm biocontrol” -discussed work using two strains of Metarhizium (fungal entomopathogen) to control wireworm in BC Questions: i. Is Met52 product registered for blackvine weevil? Are pheromones known for Agriodes species? A: Yes to both questions. ii. What impact does fungal infection have on consumption of food by larvae? A: Wireworms feed in stages, but some feeding reduction is observed. iii. Are pheromone granules grain based? A: They are cellulose base, not sure about grain. iv. Do click beetles have parasitoids that might be affected by the fungal pathogen? A: Some parasitoids have been found in adult click beetles, also larvae have been found infected with nematodes, and adult click beetles are eaten by ground beetles; most of these natural enemies seem unaffected by the fungal pathogen.

  • 1 Biological Control of Wireworm (Agriotes Lineatus) Damage To

    1 Biological Control of Wireworm (Agriotes Lineatus) Damage To

    1 Biological Control of Wireworm (Agriotes lineatus) damage to potato with Metarhizium brunneum Isabel Aida Stewart [email protected] Kwantlen Polytechnic University 100298609, AGRI 4299, Mike Bomford, 12/11/2017 2 Abstract The larval stage of Agriotes lineatus, wireworm, is a challenging agricultural pest with a broad host range. It is a soil-dwelling arthropod that may live up to 5 years before pupating. Wireworms negatively affect crop yields and render produce un-saleable. Organic production systems have few means of managing this pest and this study explores the use of an entomopathogenic fungus, Metarhizium brunneum, as a bio-control. Three treatments - M. brunneum, M. brunneum with oats, and a non-treated control - were applied beneath seed potatoes. Damage to the tubers was classified by counting tuber hole abundance (Brandl et al., 2017). No statistically significant treatment effects were observed, but the proportion of potatoes that suffered wireworm damage was 33% lower in the M. brunneum and oat treatment than the control treatment and was numerically trending towards significance. Key words: Metarhizium, biocontrol, potato, wireworm, Agriotes lineatus, entomopathogenic fungi 3 Introduction Pest development of resistance to chemical insecticides is currently a pervasive issue in agriculture and it is paramount to advance alternatives that do not threaten the environment or our future capacity for agriculture. One solution to this issue that will be explored through this study is the use of non-persistent, non-toxic biological controls, often in the form of bacterial, fungal or nematode microbial agents. The pest that our research targets is the wireworm (Agriotes lineatus), the larval stage of the click beetle, which has a broad host range including carrots, cucurbits, rutabagas, onions, sweet corn, potatoes, sugar-beets, beans and peas (Chaput, 2000).

Concluding Remarks Acknowledgments Glossary Bibliography Biographical Sketch Summary In this chapter we describe the current state of tropical insect chemical ecology in Latin America with the aim of stimulating the use of this important tool for future generations of technicians and professionals workers in insect pest management. Sex pheromones of tropical insectsUNESCO that have been identified to– date EOLSS are mainly used for detection and population monitoring. Another strategy termed mating disruption, has been used in the control of the tomato pinworm, Keiferia lycopersicella, and the Guatemalan potato moth, Tecia solanivora. Research into other semiochemicals such as kairomones in tropical insects SAMPLErevealed evidence of their presence CHAPTERS in coleopterans. However, additional studies are necessary in order to confirm these laboratory results. In fruit flies, the isolation of potential attractants (kairomone) from Spondias mombin for Anastrepha obliqua was reported recently. The use of semiochemicals to control insect pests is advantageous in that it is safe for humans and the environment. The extensive use of these kinds of technologies could be very important in reducing the use of pesticides with the consequent reduction in the level of contamination caused by these products around the world.

Med ökad majs odling finns det en möjlighet att problem med knäpparlarver ökar i denna produktion. Knäpparlarver är vanliga i Sverige och de arter som räknas som skadegörare är Agriotes lineatus (L.), Agriotes obscurus (L.) och Agriotes sputator (L.). I Sverige har ingen forskning gjorts på knäppares livscykel. Detta kan vara problematiskt när kontroll av dessa larver behövs. Knäppare gynnas i gräsmarker, exempelvis i vallar, där de har stor tillgång på underjordiska växtdelar som de äter, i denna typ av marker är också markfuktigheten högra vilket är viktigt för att egg och larver ska kunna utvecklas.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Pea leaf weevil, Sitona lineatus (L.), native to Europe and North Africa, has been introduced into many other countries around the world, including the USA and Canada. Adults are oligophagous pests on leguminaceous plants. Sitona lineatus was first recorded in Canada in 1997, near Lethbridge, Alberta. Since then, it has spread north in Alberta and west into Saskatchewan in 2007. Bioclimatic simulation models were used to predict the distribution and extent of establishment of S. lineatus in Canada based on its current geographic range, phenology, relative abundance, and empirical data.

In addition, any quotation or extract must include full attribution. 1 Molecular Phylogenetics of the Superfamily Curculionoidea (Insecta: Coleoptera) Conrad Paulus Dias Trafford Gillett March 2014 Thesis abstract This thesis examines higher-level evolutionary history within the superfamily Curculionoidea, the most speciose family-level taxon, which includes beetles commonly known as weevils. This is achieved using a phylogenetic approach incorporating the largest datamatrix yet employed for weevil molecular systematics, and includes an investigation into the prospect of obtaining short phylogenetically informative amplicons from archival museum specimens. Newly obtained DNA sequence data is analysed from a variety of mitochondrial and nuclear loci, including 92 mitogenomes assembled through the approach of next-generation sequencing of pooled genomic DNA. The resulting trees are used to test previous morphological- and molecular-based hypotheses of weevil relationships and classification schemes. Mitogenomic-derived trees reveal topologies that are highly congruent with previous molecular studies, but that conflict with some morphological hypotheses. Strong nodal support strengthens inferences into the relationships amongst most weevil families and suggests that the largest family, the Curculionidae, is monophyletic, if the subfamily Platypodinae is excluded.

However, these areas are vulnerable to destructive invasive pest species. Of these, three of the most damaging pests are weevils (Coleoptera: Curculionidae) that have relatively recently been controlled by three different introduced parasitoids, all belonging to the genus Microctonus Wesmael (Hymenoptera: Braconidae). Arguably that these introduced parasitoids have been highly effective is probably because they, like many of the exotic pest species, have benefited from enemy release.

When speaking about entomolo- gy, he will laugh and say the interest began “in the womb.” Driven by his passion for science and technology, he strives for eco- nomic security, which can be largely attributed to his upbringing in communist Poland. How do you become economically stable according to Darek? By building a company that is customer focused: embracing honesty, respect, trust and support, the rest are details. When discussing what characteristics Alpha Scents, Inc. reflects, it’s clear that the vision for the company is shaped by a desire to be loyal to all stakeholders, including customers, vendors, and his employees. Since childhood, Darek was involved with biology clubs and interest groups, fueling his passion for the sciences and leading him to study forestry and entomology during his undergraduate and master’s studies. In 1985 he started studying and experimenting with insect traps, in particular bark beetle traps baited with ethanol lures. This is how Darek started honing his speciali- zation and began asking the intriguing question of, “How could we use scents to manage insects?” In 1989, right before the fall of Communism, Darek emi- grated to Canada and in 1993 started his PhD program in the field of Insect Chemical Ecology in Syracuse, New York. After his graduation in 1998, one of his professors recommended Darek to a company in Portland, Oregon.
