Online Mapping Of Sweet Corn Pests What’s New In 2000 Chris Harding and Shelby Fleisher, Department of Enthomology Penn State During the past eight years, Pennsylvania has used phero mone lures to monitor for the three “worm” pests of sweet com: European com borer, com earworm, and the fall ar my worm. Traditionally, this in formation has been available via telephone (1-800-PEN-NIPM) or fax-back reporting. Proper monitoring allows growers to increase spray fre quency when populations are high and decrease spray fre quency when populations are low. Using trap counts to adjust spray frequency often results in fewer total sprays, offering a benefit in both dollar savings on pesticide and time saved by not spraying. Using maps to illustrate re gional pest pressure has many advantages over telephone or fax-back reporting. Maps enable intuitive comparisons of trap counts. This regional view bene fits all participants by increasing awareness of nearby pest densi ties. For example, the fall ar myworm and com earworm im migrate into Pennsylvania from the south. Maps from the 1999 season illustrate that before these pests immigrate into Penn sylvania, their densities increase in Delaware and Maryland. This provides Pennsylvania growers with a two-week warning before serious immigration of these pests occur in Pennsylvania. A website to display maps of the pheromone trap captures was launched last year with good results. One hundred farms in four states Delaware, Mary land, New York and Pennsylva nia participated. The Website providing maps of the trap cap tures was accessed approxi mately 1,200 times during the season. The Website provides access to both current and historical pheromone and blacklight trap captures and includes informa tion on integrated pest manage ment (IPM). Data is reported in a buffer point format with larger circles representing higher moth captures. Clicking on any of the capture points links to a time series for that pest at that loca tion. Users can also access the time series for all pests at a given location. The sweetcorn pest monitor ing website can be accessed at http://www.ento.p su.edu/vegetable/sweetcom/ If you access the site now, you will see maps for 1999. The last nlap created at the end of the season in 1999 will be the de fault. Try going to earlier dates to see more valuable informa tion. For example, go to the CEW maps from Aug. 14, 1999 to Sept. 11,1999 to see the major CEW immigration in 1999.

We anticipate new maps from the 2000 growing season to be coming on-line in early to mid-June. The 2000 growing season will see an increased number of trap ping locations, the addition of European corn borer phenology and improvements to the re sources materials. New Jersey is joining the regional trap catch program, and new sites are being added in Pennsylvania, which will increase the total trap sites to approximately 215. Phenology modeling (predict ing the time of occurrence of specific life stages based on ac cumulated degree days) for the European corn borer will help provide advanced warning on the timing of both first and second generation European cornborer flight. The phenology models will be included with the time series. Resource materials have been developed with the goal of improving access to IPM information. Many of the resources devel oped as part of this project were formerly only accessible through the county extension office. For example the Pennsylvania com mercial vegetable production Heavy Duty Bale Movers • Available with either quick attacl (specify make or model) or 3PT hitch/loader boom mounting hardware • Easily change spear confii • Designed to move either round 01 3 PT Hitch Bale Movers • Easily change spear configurat Lancaster Fanning, Saturday, May 27, 2000-A29 • 2500 lb. capacity • 1500 lb. capacity PL F4 PLF 2500 (for compact tractors) recommendations, a ten-dollar purchase at the county exten sion office will also be available online at no cost. Following are some additional resources available from this site: •Vegetable insect pest sheets: Penn States pest sheets for vege table insect pests found in Penn sylvania. •Vegetable Gazette on-line: An on-line version of the popu lar horticultural magazine. This link includes access to back issues. •IPM references: Some of the best and most recent IPM guides available. •CDMS: A privately held cor poration which provides pesti cide labels and MSDA for most agricultural chemicals. These educational resources along with the sweetcorn trap ping network are accessible from the following site; http://www.ento.psu.edu/ vegetable/ If you are interested in being involved in the trap capture pro gram or have ideas as to how we can improve these resources, contact me, Chris Harding, at cxh4o2@psu.edu.
