Summary:
We are submitting a three year Extension project to establish an insect trapping network in Kentucky and Tennessee with plans to add sites in Illinois and Missouri during the second year. Our four state study area of western Kentucky and Tennessee, southern Illinois and southeastern Missouri is located in a unique ecological situation. Our four-state study area lies south of the colder winters extending from the Cumberland Plateau to the east across the northern prairies to the Ozark Plateau in the west; and north of the very mild winters of the deepsouth below the Appalachian fall line. Within this area is the confluence of several major rivers of the Mississippi Drainage (Ohio, Cumberland, Tennessee, and Mississippi Rivers.). It is in the northern sweep of the USDA Plant Hardiness Zone 6.
The project will focus on four species of foliar feeders (armyworm, black cutworm, corn earworm, fall armyworm) and the stalk boring pests European corn borer and southwestern corn borer. These species occur in the four states and threaten a large variety of crops including corn (field, pop, and sweet) cotton, grain sorghum, pasture and hay grasses, peppers (bell and hot) and wheat. Sex pheromones are available as commercial lures and data sets describing temperature dependent development are available.
Data from the traps will be used to alert producers to potentially damaging pest outbreaks, warning them that crops need to be checked for infestations. This will enable them to make more accurate applications when needed and to reduce the potential for unneeded applications. Increasing the availability and usefulness of this information by the production sector can reduce potential human and environmental exposure while providing an economic benefit to the producer.
Objectives: Goals: Increase the availability and use of PBT trap data by clientele in making timely pest management decisions. Reduce the number of inappropriate insecticide applications, and increase time management efficiency. Objective: Increase the utility of the information Allow comparison of data on an area basis. This will allow one to see information from an area that may be expected to have a population increase earlier than the local location e.g. IL looking at TN data for armyworm or vise versa for black cutworm. Method standardize trapping methods across state locations. Allow comparison of current year data with past year(s) data. This will provide a general idea of risk in the current year. Method Archive data in a standard data base format, and utilize the data on the clientele interface. Allow comparison of current year data with data from outbreak year. This (when available) will provide a better notion of risk in the current year. Method Archive data in a standard data base format, and utilize the data on the clientele interface. Objective: Increase the ease of use of this data: Display data for all states, locations, and pests on a single web site. Display the data in graphic rather than numeric form. Show data for 1.) current year, 2) past year, and 3) outbreak year. |

Results From report submitted by the PI to USDA CRIS report system PROGRESS: 2007/08 TO 2008/07 OUTPUTS: The Kentucky IPM program has been monitoring the moth flights of major field crop pests, developing sets of data and trapping techniques that will allow entomologists to make inferences about when and if insect populations will develop into economically important populations. This information can save time and money by alerting producers and consultants to critical periods they will need to be in fields looking for the insect and if they are relatively more or less abundant. Finding the pest early allows more time for spray decisions, and if an application is needed it can be done in a timely fashion to allow for an economic benefit. Two statewide news articles mailed to all weekly and daily newspapers announced the formation of the Insect Trapping Network. To increase knowledge, use and awareness of the data provided by the network, two trainings were held for County Extension Agents as well as two presentations for the members of the Kentucky Agriculture Chemical Dealers Association. In Tennessee, additional presentations were made at county-based meetings. To facilitate usage, the IPM insect data Web pages (http://www.uky.edu/Ag/IPM/ipm.htm) we presented the insect trap counts in a graphic format to increase ease of use. Insect traps at four sites, two in Kentucky and two in Tennessee, were checked weekly, and the data collected were made available each Friday from March 1 through September 30 on the Kentucky IPM web site as well as being published weekly in Kentucky Pest News. Twenty-five articles relating to the use of the insect trap data were published in Kentucky Pest News. The articles included two alerts/warnings for potential damage from armyworms based on the numbers from the insect trap counts as well as alerts for corn earworms and fall armyworms. Alerts/warnings were also sent via e-mail to County Extension Agents and Extension Specialists. Extension entomologists were available by phone and e-mail to any agent, specialist, producer or consultant who had questions concerning the use of the trap data or the alerts issued. Displays describing the project and the alerts were set up at the University of Kentucky Field Days for western and central Kentucky. To collect information on this project, pre- and post-season surveys were conducted involving active certified crop advisors. Both traditional paper and electronic web based surveys were developed and used to collect information on how the information from alerts/warnings was used. PARTICIPANTS: P. Lucas and D. Johnson provided overall coordination of the project. Lucas operated the trap line located in Princeton, managed collection and archiving of data from all sites, maintained web pages, developed project logic model, and developed and conducted surveys. Johnson provided entomological expertise for Kentucky. This included involvement in educational efforts, use of data to make predictions and issue alerts/warnings for Kentucky. Johnson also disseminated predictions and recommendations to end users. R. Patrick responsibilities included operation of trap lines in Tennessee, entomological expertise and educational efforts for Tennessee. The University of Tennessee was a sub-contractor for this project. Two training sessions held for County Extension Agents offered four professional development hours. Four meeting presentations offered continuing education hours in Pest Management for Certified Crop Advisors. TARGET AUDIENCES: Target audience served by the project included producers, agricultural businesses, crop advisors and Extension employees in Kentucky, Tennessee, Indiana, Ohio and Illinois. Formal classroom instruction on how to use insect traps and insect trap data included two trainings for County Extension Agents, two presentations for the members of the Kentucky Agriculture Chemical Dealers Association and two presentations at IPM Training Schools. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period. IMPACT: 2007/08 TO 2008/07 A pre-season survey of active Certified Crop Advisors found that 74% had looked at or used the information provided by the IPM Trapping Network. Sixty-eight percent have used the information to decide they needed to check fields for a pest, and 44% have used the information to help make a decision to spray a crop. At the end of the growing season, certified crop advisors were again asked to complete a survey. Thirty-one percent said the information provided alerted them to a problem they would otherwise have missed. Fifty-six percent said using the information saved them an average of 2.5 hours with the average value of their time being $21 an hour. When ask to rate on a scale of 1 to 5 their knowledge of how insect traps work, post season survey values increased to 3.6 from 3.2. When ask to rate their understanding of how to use the data provided by the insect trapping network, post-season values increased to 3.4 compared to a pre season value of 3.1. The ability to use this knowledge was demonstrated by 24 percent of those responding indicating they used the trap data to help them make a decision not to spray a crop resulting in 20,875 acres of field crops not being sprayed with an insecticide. In the spring of 2008, the Kentucky IPM Trapping Network, using record trap counts for armyworm moths at locations in Princeton and Lexington, was able to issue an alert that the probability was high that armyworm populations could reach economically important populations. This information not only benefited Kentucky but also was used by Extension Specialists at the University of Illinois, Purdue, The Ohio State University and a Canadian Entomologist to issue warnings for producers in their areas to be alert and checking their crops. Fifteen counties in Kentucky responded to an electronic survey seeking information about damages caused by armyworms. In the fifteen responding counties, 3,700 acres were checked as a result of the issued warnings. The warning saved approximately 64,250 bushels of corn, 150 tons of pasture and 5,875 bushels of wheat, or approximately $342,973.00. PUBLICATIONS (not previously reported): 2007/08 TO 2008/07 1.
