A recent identification of the two-component aggregation pheromone invasive stink bug species, Halyomorpha halys (Stål), in association with a synergist, has greatly improved ability to accurately monitor seasonal abundance and distribution this destructive pest. We evaluated attraction H. black pyramid traps baited lures containing alone, synergist methyl (2 E ,4 ,6 Z )-decatrienoate (MDT) two combination. Traps were deployed around areas agricultural production including fruit orchards,...
Reliable monitoring of the invasive Halyomorpha halys abundance, phenology and geographic distribution is critical for its management. adult nymphal captures on clear sticky traps in black pyramid were compared 18 states across Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest Western regions United States. Traps baited with commercial lures containing H. pheromone synergist, deployed at field sites bordering agricultural or urban locations host plants. Nymphal greater than those...
Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled annual seasonal common pest, Helicoverpa zea (Boddie), based on three suitability zones throughout North America using four decades soil temperatures: southern range (able persist through winter),...
Abstract As part of an insect resistance management plan to preserve Bt transgenic technology, annual monitoring target pests is mandated detect susceptibility changes toxins. Currently Helicoverpa zea (Boddie) involves investigating unexpected injury in crop fields and collecting larvae from non-Bt host plants for laboratory diet bioassays determine mortality responses diagnostic concentrations To date, this approach has not detected any significant change the known range baseline toxins,...
Field tests in 2010–2011 were performed New York, Minnesota, Maryland, Ohio, and Georgia to compare Bt sweet corn lines expressing Cry1A.105 + Cry2Ab2 Cry1Ab with their non-Bt isolines, without the use of foliar insecticides. The primary insect pest all locations during trial years was Heliocoverpa zea (Boddie), which is becoming most serious United States. At harvest, ears measured for marketability according fresh market processing standards. For processing, least squares regression showed...
Abstract Mean daily progeny production by Trichogramma minutum (“Maine strain”) was 15.2 in Choristoneura fumiferana and 10.9 Sitotroga cerealella eggs. Total higher S. , but not significantly different from that of C. Significantly more eggs were deposited T. the first day than subsequent days regardless host. We found no significant relationship between produced females male death as previously reported. Ratio females:males decreased with increasing age opposition activity mother. The...
Bell peppers are a valuable vegetable crop in the U.S. Management of pepper insects and diseases relies on chemical control options. Because there relatively few options available for pest management, it is critical to make efficacious application pesticides. Foliar spray coverage retention middle bottom bell canopies were compared using fluorescent dyes food coloring, respectively. Several delivery systems evaluated, including air-induction twin-fan nozzles, air-assisted with conventional...
Invasive species threaten the productivity and stability of natural managed ecosystems. Predicting spread invaders, which can aid in early mitigation efforts, is a major challenge, especially face climate change. While ecological niche models are effective tools to assess habitat suitability for such have rarely been created invasive pest with rapidly expanding ranges. Here, we leveraged national monitoring effort from 543 sites over 3 years factors mediating occurrence abundance brown...
Populations of the European red mite (ERM), Panonychus ulmi (Koch), from apple orchards throughout New York State were evaluated by laboratory bioassays to assess range susceptibility cyhexatin. As an indicator cyhexatin adult ERM, a 72-h open-leaf residual bioassay was more sensitive than 24-h slide-dip bioassay. At 100 ppm, 12-fold difference in residues found between resistant ERM population commercial orchard and susceptible field population. The same populations at 75 ppm only 3-fold....
Seedling debarking damage in plantations of various conifer species Maine was found to be caused by Hylobius congener Dalla Torre, Schenkling, and Marshall. H. has not been reported the literature as a pest living trees. During 1982 1983, influences duff, slash, intrasite location, stumps, site preparation methods on seedling were investigated weevil populations at sites compared. Debarking black spruce, Picea mariana (Mill.) B.S.P., lower: 1) when duff scraped back from bases, 2) interior...

A simulation model of the sterile insect release (SIR) method population suppression was developed as a modeling exercise by advanced students integrated pest management (IPM). Objectives were to create an instructional that would demonstrate principles and operation SIR technique undergraduate IPM students, allow users see effects relaxing or violating various assumptions basic model. In particular, influence dispersal, spatial distribution wild insects, uncertainty about initial density,...
The North Central Consumer Horticulture Integrated Pest Management Working Group developed an online learning module entitled, “Introduction to Diagnostics for Master Gardener Volunteers: Approaches Plant Diagnosis.” is in the campus or learn section of eXtension and composed three parts: part 1 covers difficulties diagnosing plant problems; 2 discusses how gather information necessary diagnostic process; 3 Ohio State Fact Sheet, “20 Questions on Diagnostics.” self-paced takes a minimum...
Laboratory bioassay techniques were developed for testing the susceptibility to hexythiazox of European red mite (ERM), Panonychus ulmi (Koch). These used establish baseline eggs and larvae a New York population ERM. Winter summer tested by both contact ovicidal residual larvicidal exposure. Summer nine times more susceptible than winter (LC50 values 2.2 20.0 ppm, respectively). Susceptibility decreased when treated within 2 d hatch. When exposed residues, mites usually died in...
A pilot project focused on IPM for home gardens was conducted by establishing demonstration trials at public garden sites in three cities (Wooster, Stow and Twinsburg) northeastern Ohio, USA. Three strategies disease insect pest management were compared: 1) “low maintenance” with emphasis cultural practices, a style common among gardeners lacking time laborintensive gardening; 2) “integrated biorational”, utilizing integrated biorational tactics, pesticides applied only when needed; 3)...
The North Central Consumer Horticulture Working Group developed and distributed a 14-question survey to determine the confidence of north-central U.S. extension Master Gardeners (MGs) in making integrated pest management (IPM) recommendations their use IPM. online was completed by 3842 MGs Illinois, Indiana, Kansas, Michigan, Minnesota, Missouri, Nebraska, Dakota, Ohio, South Wisconsin. indicated they personally engaged range IPM practices, including prevention, monitoring, cultural,...
Infestation of European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), a key pest peppers (Capsicum annuum L.), was studied to explore the cause infestation differences in pungent versus sweet types peppers. Our objectives were determine whether O. adults show an ovipositional preference or larval development effects among pepper that vary levels capsaicin and dihydrocapsaicin, which is measured Scoville heat units (SHU). Five with range hotness tested: bell (0 SHU),...
