Exotic Pests Keep Your Eyes Open for Invasive Pests Des Moines’ Pesticide Recertification Training 2/05/15 Michael Bush, Ph.D. WSU Extension- Yakima WA State Exotic Pest Team • Members consist of WSU Extension & Researchers PLUS • WA State Dept. of Agriculture Exotic Pests • Exotic species are not native to Washington State. • Plant, animal, microbes • The impact of each exotic species on agriculture (& forestry) varies • If they survive, their numbers can explode.

WSU Exotic Pest Team seeks to get ahead of this invasion curve. How to accomplish this • Recruit more eyes (& photo lenses) to detect exotic pests sooner • Invasive pests detected over past 20 years in WA State (n~ 60) • Survey target = WSDA- funded projects • Private citizens = ag consultants, growers, homeowners, Master Gardener volunteers. An Insect Pest of Concern Brown marmorated stink bug, Halyomorpha halys • Emerge as a crop pest • It will impact vegetable & fruit production • Emerge as a nuisance pest • It will impact local residents. Brown Marmorated Stink Bug Distribution in 2009 1st detection – Ø In 2010, reported in Allentown, PA 2001 Ø Michigan Ø Ohio Ø Researchers feel that it is only a matter of time. 1st Detection in Washington • Brown Marmorated Stink Bug • Sept. 2010- Vancouver, WA • Maple & deciduous trees (Tree of Heaven) 2013 Detections in Washington • Established populations (= two life stages): • Clark & Skamania • Detections: Klickitat, Yakima, Walla Walla and Thurston Co. Wiman, OSU 2013 For Each Exotic Pest . Can we recruit extra “eyes” & detect these pests sooner making prevention easier? For Each Exotic Pest . Early Detection = Applicators More rapid assessment = Exotic Pest Team If we can detect these pests sooner, will it allow for a more rapid response? Applicator Recruitment Starts Here Invasive = BMSB- Look for unique damage • Vegetable crops: tomatoes, green bean, asparagus, pepper, squash & pumpkin. • Agronomic crops: soybean, corn. • Fruit crops: peach, Asian pear, pear, apple, cherry, raspberry, grape, currant. Watch out for BMSB Adults As Well • Overwinters as adults that emerge in May • Goes through 1 to 2 generations per season Remember BMSB Life Cycle • Keep your eyes open for unusual bug nymphs as well! What to do if you suspect or catch Brown Marmorated Stink Bug ? 1) Take it to your local WSU Extension Office (or Diagnostic clinic) 2) Call WSDA Pest Program 360 902-2070 1 877-9-INFEST Brown Marmorated Stink Bug (BMSB) Impacts on homeowners Winter aggregaons! Brown Marmorated Stink Bug (BMSB) Impacts on homeowners Apple Soybean Wanted Poster Dead or Alive Stink Bugs At Large in Washington State Adult Stink Bugs are a well-known family easily recognized by shield-like shape, five-segmented antennae, and for producing a most disagreeable odor when provoked. They can come in various shades of green, brown and black. There are a number of species in this family that are known for unwanted feeding and vandalism of plant crops like raspberries, apples, tomatoes and peppers. They may attack and damage ornamental plants en mass. Boring to search for invasive pests especially if they are not out there yet! • Other common stink bugs found in Eastern Washington • Rough stink bug • Consperse stink bug • Green stink bug • Red-shouldered stink bug • Consolation prize This will give researchers a snapshot of diversity. Results to date: • Wanted Poster out August ‘14 • Initially, distributed by WSU Statewide Master Gardener Program (Cisco Morris) • Over 135 samples have been submitted as photos or as physical samples from 17 Counties. 2014 BMSB Detections in Washington • Established populations (= two life stages): • 2013-Clark, Skamania • 2014- Yakima & Walla Walla • New Detections: Franklin, Cowlitz, Pierce, King & Snohomish.

  • Phylogenetic Relationships and Distribution of the Rhizotrogini (Coleoptera, Scarabaeidae, Melolonthinae) in the West Mediterranean
    Graellsia, 59(2-3): 443-455 (2003) PHYLOGENETIC RELATIONSHIPS AND DISTRIBUTION OF THE RHIZOTROGINI (COLEOPTERA, SCARABAEIDAE, MELOLONTHINAE) IN THE WEST MEDITERRANEAN Mª. M. Coca-Abia* ABSTRACT In this paper, the West Mediterranean genera of Rhizotrogini are reviewed. Two kinds of character sets are discussed: those relative to the external morphology of the adult and those of the male and female genitalia. Genera Amadotrogus Reitter, 1902; Amphimallina Reitter, 1905; Amphimallon Berthold, 1827; Geotrogus Guérin-Méneville, 1842; Monotropus Erichson, 1847; Pseudoapeterogyna Escalera, 1914 and Rhizotrogus Berthold, 1827 are analysed: to demonstrate the monophyly of this group of genera; to asses the realtionships of these taxa; to test species transferred from Rhizotrogus to Geotrogus and Monotropus, and to describe external morphological and male and female genitalic cha- racters which distinguish each genus. Phylogenetic analysis leads to the conclusion that this group of genera is monophyletic. However, nothing can be said about internal relationships of the genera, which remain in a basal polytomy. Some of the species tranferred from Rhizotrogus are considered to be a new genus Firminus. The genera Amphimallina and Pseudoapterogyna are synonymized with Amphimallon and Geotrogus respectively. Key words: Taxonomy, nomenclature, review, Coleoptera, Scarabaeidae, Melolonthinae, Rhizotrogini, Amadotrogus, Amphimallon, Rhizotrogus, Geotrogus, Pseudoapterogyna, Firminus, Mediterranean basin.

  • Effects of Climate Change on the Dispersion of White Grub Damages in the Austrian Grassland
    1st Scientific Conference within the framework of the 8 th European Summer Academy on Organic Farming, Lednice na Morav ě, Czech Republic, September 3–5, 2008 Effects of climate change on the dispersion of white grub damages in the Austrian grassland Hann, P. 1, Grünbacher 1, E.-M., Trska, C. 1 & Kromp, B. 1 Key words: grassland, white grub damage, climate change, drought, Austria Abstract Recent changes in occurrence of agricultural pests in Austria might already reflect climate change phenomena. In this study, an inventory of white grub (Melolontha melolontha, Amphimallon solstitiale and Phyllopertha horticola) damages in Austrian grassland including organic cultivation was performed by questioning plant protection consultants of 74 Agricultural County Chambers. Altogether, a cumulated 14.800 hectares of white grub damages were recorded. From 2000 onwards, a steady increase of white grub damages occurred with a climax in the year of heat and drought 2003. The infested fields extended along the alpine main ridge from Vorarlberg up to the alpine foreland. Additionally, southern slopes of the Danube valley in Upper and Lower Austria were affected. Very likely, the damages were mainly due to the garden chafer P. horticola. From 2004 to 2006, the extent of damages decreased again all over Austria. By studying meteorological data, it became obvious that the damaged areas were mainly situated in regions with a strong precipitation deficit. On-farm investigations performed in 2007 strengthened the hypothesis that drought and elevated soil temperatures might be the decisive factors for a strong development of grub populations and subsequent feeding damages. Additionally, drought can increase the effects of grub damage by delaying the regeneration of the damaged sward.
