<br />
<b><span style="color: red;">Important</span> - Re-Subscribe to receive our Weekly Updates</b><br />
Visit our new site <span style="color: red;">and signup to receive the timely insect pest information</span> you’ve come to expect from us, as well as the Insect of the Week, delivered to your inbox. [Due to <a href="https://www.fightspam.gc.ca/eic/site/030.nsf/eng/home" target="_blank">Canada's Anti-Spam Legislation</a> and just plain good manners, we cannot copy your subscription to the Blog over to our new website.]<br />
<br />
<b>Same great information</b><br />
The new website is organized like the Blog to keep information including monitoring protocols and risk maps easy to find. But, the website is a work in progress so some information might not be available there yet. Rest assured, the PPMN Blog will stick around so you can look through our past posts and find other information; however, no new information will be posted there after this week (July 10, 2020).<br />
<br />
<b>You made us a success</b><br />
Thank you for using the Blog since it was launched in 2015! We are able to transition to a website now because the Blog is so popular. The new website overcomes some of the Blog shortcomings (e.g., data storage limits). In the future, we hope to introduce new tools to improve insect pest monitoring and insect pest management. Over the coming months, we will work to add information, pictures and links.<br />

Each week, we'll pick a crop and list the insects that attack it along with additional helpful information. The insect list is based on the information found in the <a href="https://prairiepest.ca/wp-content/uploads/2019/01/AAFC-Field-Guide_ENGLISH_HQ_Print_new-cover_June-2018.pdf">Field Crop and Forage Pests and their Natural Enemies in Western Canada: Identification and Management</a> field guide.

Happy Birthday Canada!<br />
<br />
Warmer temperatures last week continue to move our growing season forward and there are more insects to prioritize on scouting lists again this week. Bertha armyworm pheromone monitoring numbers are coming in as cooperators work with their provincial networks to help assess risk levels in the form of cumulative moth counts. We are also poised for wheat midge emergence across the prairies and we dedicate this Weekly Update and <a href="http://prairiepestmonitoring.blogspot.com/2020/07/john-frederick-doane-14-april-1930-21.html" target="_blank">remember Dr. John Doane</a>, an entomologist whose research on this pest and many other species contributed significantly to insect pest management on the Canadian prairies.<br />

<br />
John Frederick Doane quietly passed away on May 21, 2020, in his home in Saskatoon, at the age of 90 years. Having grown up on a farm north of Toronto, John developed an interest in entomology at a young age, and began collecting insect specimens common to southern Ontario. John received his B.S.A. in 1954 from the Ontario Agricultural College, now the University of Guelph; specializing in entomology. Pursuing these interests, John immediately enrolled in graduate studies at the University of Wisconsin, completing both his M.Sc. (1956) and his Ph.D. (1958). Shortly after graduating, he began a research career in agricultural entomology, receiving an Research Scientist position at the Agriculture Canada Research Station in Saskatoon that same year. Interestingly, this cadre of Research Scientists at the Centre still had a significant number of first generation entomologists appointed to the Dominion Entomological Laboratory at Saskatoon.<br />

John adapted very quickly to the agricultural industry on the prairies, and his research over the years has significantly contributed to insect population monitoring. His first research assignment was to assess and describe the ecology and behaviour of wireworms, a major pest of field crops at the time. John began by investigating the ovipositional behaviour and fecundity of adults, as well as the effects of soil moisture and temperature on wireworm egg survival. His studies, related to the response of wireworm larvae to carbon dioxide levels, contributed to the development of trapping and monitoring tools for larval populations. In the early 1980s, Saskatchewan experienced an unexpected outbreak of wheat midge (<i>Sitodiplosis mosellana</i>). John was asked to assemble a multidisciplinary research team with the objectives to determine the biology and ecology of this new threat to wheat production in the prairies. His research promptly yielded important contributions: (i) the discovery of a significant biological control insect (<i>Macroglenes penetrans</i>), and (ii) the development of a sound wheat midge population monitoring protocol. Through the successful implementation of conservation techniques, <i>M. penetrans</i> now controls an average of >30% of the wheat midge across Saskatchewan annually. A study in the 1990s, showed that the dollar value of the parasitoid to the agriculture industry over the 10 years, was in excess of $248.3 million (equivalent of $422.5 million today). The second highlight, a soil extraction protocol for wheat midge larval cocoons, provided a unique population density and distribution monitoring tool for both the pest wheat midge and it’s biological control agent. This tool is still utilized today to forecast the risk to wheat production; the survey results being provided as mapped forecasts for producers on an annual basis. Given the success of biological control agent (<i>M. penetrans</i>), John collaborated with international colleagues at CABI in Switzerland, to assess the viability of importing a second biocontrol agent for control of wheat midge. This resulted in the successful introduction and establishment of <i>Platygaster tuberosula</i>. In the late 1980s, wheat production south of the USA border was seriously threatened by Russian wheat aphid (<i>Diuraphis noxia</i>). In response to this new threat, John manufactured and installed a series of suction traps as an early-warning system, from southern to northern Saskatchewan. The 30ft high traps were designed to collect migratory aphid adults being transported north on wind currents from infestations in the USA. The results indicated that southwest SK was occasionally at low risk, but the threat was significantly less than south of the border.<br />
<br />
John was appointed Head of the Integrated Pest Management Section of the Saskatoon Research Station in 1982, and the Head of the amalgamated Cereals Protection Section in 1989. John served as E.S.S. President in 1967 and 1978, and served a term as a member of the E.S.C. Governing Board. He will also be remembered as a founding member of the national AAFC Biological Control Working Group, a group that is still very active in 2020. He retired in 1993, taking an extended self-guided tour of south east Asia, including India and Malaysia. Upon his return, John remained active in retirement, co-authoring several scientific articles, most recently a bio-climate modelling paper on wheat midge in 2020.<br />

Soil moisture conditions in May and June can have significant impact on wheat midge emergence. Adequate rainfall promotes termination of diapause and movement of larval to the sol surface where pupation occurs. Insufficient rainfall in May and June can result in delayed movement of larvae to the soil surface. Elliott et al. (2009) reported that wheat midge emergence was delayed or erratic if rainfall did not exceed 20-30 mm during May. Olfert et al. (2016) ran model simulations to demonstrate how rainfall impacts wheat midge population density. Our wheat midge model (Olfert et al. 2020) indicates that dry conditions may result in:</span><br />

Pea leaf weevil resembles the sweet clover weevil (<i>Sitona cylindricollis</i>) but the former is distinguished by three light-coloured stripes extending length-wise down thorax and sometimes the abdomen. <i>All species of Sitona, including the pea leaf weevil, have a short snout</i>. </span></span><br />

<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>Larvae</b> develop under the soil and are “C” shaped and milky-white with a dark-brown head capsule ranging in length from 3.5-5.5 mm (Figure 2). Larvae develop through five instar stages. After hatching, larvae seek and enter the roots of a pea plant. Larvae will enter and consume the contents of the nodules of the legume host plant. It is the nodules that are responsible for nitrogen-fixation which affect yield plus the plant’s ability to input nitrogen into the soil. Consumption of or damage to the nodules (Figure 3) results in partial or complete inhibition of nitrogen fixation by the plant and results in poor plant growth and low seed yields.</span><br />

Aphids can cause significant damage to fields and increase crop losses but low densities in a grain field sometimes have little economic impact on production. This is especially true if the aphid’s natural enemies (beneficial insects) are present in the field because they can keep the aphids under control.<br />

<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="font-family: "arial" , "helvetica" , sans-serif;"><b><br /></b></span><b><span style="font-family: "arial" , "helvetica" , sans-serif;">Wind trajectory and cereal rust risk assessment and need for in-crop scouting in the Prairie region, June 23-29, 2020</span></b></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b><span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></b><b>1. Pacific Northwest</b></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>i. </b>There were a moderate number of reverse wind trajectories that passed over the PNW region and into the prairies. Locations with the highest number of days with events (4-5) with reverse trajectories from the PNW included: Lethbridge (5), AB; and Gainsborough (5), Kindersley (4), and Regina (5) SK. The remaining locations in Alberta, Saskatchewan and Manitoba had 1-2 days with events, except for Fort Vermilion, Grande Prairie, Manning, Sedgewick and Wanham, AB, which had no events from June 23-29, 2020 (Table 1). </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>ii. </b>Currently there appears to be relatively low levels of stripe rust development on commercial winter wheat crop in the PNW. The spring wheat crop is somewhat smaller in acreage and appears to have limited stripe rust development, while fungicide applications may limit further stripe rust development in PNW spring wheat crops. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>iii. </b>Prairie temperatures were warmest in MB and eastern SK and seven day cumulative varied across the prairies (Figure 7). Average 7 day temperatures continue to be warmest across MB and eastern SK and coolest across most of AB (Figure 7) . The weekly average temperature at Winnipeg (20.8 °C</span><span style="font-family: "arial" , "helvetica" , sans-serif;">) was 6</span><span style="font-family: "arial" , "helvetica" , sans-serif;"> °C</span><span style="font-family: "arial" , "helvetica" , sans-serif;"> warmer than Grande Prairie. Cumulative rainfall for the past 7 days was variable (Figure 9). Cumulative 30 day rainfall was greatest across central regions of AB. Rainfall amounts were lower across the southern prairies (Figure 10). </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>iv. </b>Winter wheat crops are progressing into flowering or are finishing flowering, while Prairie spring wheat development ranges from tillering to booting/head emergence. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>v. </b>There have been reports of stripe rust in western Idaho and on June 16 and June 30, 2020 from southern Alberta, specifically the Counties of Lethbridge, Cardston, and Forty-Mile. On June 19, 2020 there was a report in Alberta with the observation of stripe rust in winter wheat yield trials at AAFC Beaverlodge. Stripe was also just observed in wheat plots at the University of Saskatchewan in Saskatoon (Randy Kutcher, personal communication). Given the appearance of stripe rust in three counties in southern Alberta, at Beaverlodge in the Country of Grande Prairie, and the first observations in the Saskatoon area of Saskatchewan, farmers in these regions should be on the look out for stripe rust in wheat. Special focus should be on wheat fields seeded to varieties rated as susceptible or moderately susceptible. These recent observations indicate that Prairie regional sources of inoculum may become more important with further crop and disease development. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>vi. Thus, as of June 29, 2020 the risk of stripe rust appearance from the PNW or from regional sources is low to moderate (Figure 12)</b>. However, some locations may be at an increased stripe rust risk, especially where there were 4-5 reverse trajectory events from the PNW or in Prairie regions where stripe rust has been reported.</span><br />
<div>
<br /></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<b style="font-family: Arial, Helvetica, sans-serif;">2. Texas-Oklahoma corridor</b><br />
<div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>i. </b>Currently, farmers in Texas and Oklahoma have or will soon be finished harvesting their winter wheat crops, and thus no longer represents a significant source of cereal rust inoculum for movement into the Prairie region.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>ii. Thus, as of June 29, 2020 the risk of leaf and stripe rust appearance from the Texas-Oklahoma corridor is nil and scouting for these diseases is not urgent.</b> </span></div>
<div>
<br /></div>
<div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>3. Kansas to Nebraska corridor </b></span></div>
<div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>i. </b>Currently there appears to be relatively low levels of stripe rust development in the Kansas to Nebraska. Looking at specific locations in Prairie region and reverse trajectories, only 8 of 29 locations had only 1-2 days each with reverse trajectories originating over the states of Kansas and Nebraska from June 23-29, 2020, with the remaining locations having zero. Locations with 1-2 days with events included: Gainsborough (2), and Yorkton (1), SK; and one event each for Brandon, Carman, Dauphin, Portage, Russell, and Selkirk, MB. The remaining locations had no events from June 23-29, 2020 (data not shown). </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>ii. </b>Prairie temperatures were warmest in MB and eastern SK and seven day cumulative varied across the prairies (Figure 7). Average 7 day temperatures continue to be warmest across MB and eastern SK and coolest across most of AB (Figure 7) . The weekly average temperature at Winnipeg (20.8C) was 6C warmer than Grande Prairie. Cumulative rainfall for the past 7 days was variable (Figure 9). Cumulative 30 day rainfall was greatest across central regions of AB. Rainfall amounts were lower across the southern prairies (Figure 10).</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>iii. </b>Winter wheat crops are progressing into flowering or are finishing flowering, while Prairie spring wheat development ranges from tillering to booting/head emergence. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>iv. </b>In Kansas the winter wheat crop is rapidly maturing with harvesting occurring in some areas, and thus no longer represents a significant source of rust inoculum. The Nebraska winter wheat crop has mostly headed and in some areas is starting to turn with harvest 1-2 weeks away. With the Nebraska winter wheat crop progressing towards maturity and harvest, and given limited reports of disease, this state is becoming less of a potential source of rust inoculum. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>v. Thus, as of June 29, 2020 the risk of leaf and stripe rust appearance from the Kansas-Nebraska corridor is limited and scouting for these diseases is not urgent (Figure 13).</b></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b><br /></b></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>vi. </b>There continue to be reports of low levels of stripe rust in South Dakota and Wisconsin. Thus, given the proximity to the Prairie region, these reports serve as a warning that farmers and crop scouts in the central to eastern Prairie region of Canada should be on the look out for stripe rust, especially in winter wheat fields.</span></div>

<div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b><span style="font-family: "arial" , "helvetica" , sans-serif;">4. </span>Rust appearance in the Prairie region</b></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>i. </b>Where farmers or consultants noticed stripe rust development on winter wheat in the fall of 2019, it is recommended to scout winter wheat fields that have resumed growth in spring 2020. Scouting is especially critical where the variety being grown is susceptible to stripe rust. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><b>ii. </b>Currently, there have been five reports of the initial appearance of stripe rust on Alberta winter wheat on June 5, 16, 19, and 30, 2020 in the Counties of Lethbridge, Cardston, and Forty-Mile in southern Alberta and in the County of Grande Prairie in the Peace Region of Alberta (Figure 2). On July 2, 2020 there was also an initial report of stripe rust in the Saskatoon region (R. Kutcher, personal communication). <b><span style="color: red;">Given the appearance of stripe rust, farmers in these regions should be on the look out for stripe rust in wheat.
