Insects on the Move!!! 2014 Version What’s Here? What’s Coming? Dr. Carol Sutherland Extension Entomologist, NMSU & State Entomologist, NM Dept. Agriculture Alien arthropods have arrived in the US throughout our history, traveling as we have….ships, wagons, trains, planes, automobiles or by their own power. The earliest arrived with settlers who brought familiar crops & livestock from their homelands. Long Established Invasive Pests in U.S. Hessian Fly—small grains Codling Moth—apple, pear European Gypsy Moth German Cockroach Japanese Beetle Hardwood trees Homes, building Soybeans, landscapes Laws, Regulations, Inspections & Enforcement Since 1912---and still…. • About 1 in 7 species entering the U.S. become established • Invasive species cost the U.S. economy >$150 billion/yr • Impacts: negative economic, environmental, health, & productivity; surveys, control & suppression costs=$$$ US Customs & Border Protection At U.S. ports But they can put monkey wrenches into landscape management & IPM programs. What crops/plants/sites are affected? How? Impact? Can be an additional pest to scout, evaluate, manage What methods/treatments control the pest/damage? Keys to Alien Arthropod ‘Success’…. -Avoid detection, well hidden -Broad host ranges -Can survive in a variety of habitats -Can survive ‘genetic bottlenecks,’ small populations -Mobility, including hitchhiking -Efficiently & highly prolific -No effective natural enemies -Invasive, competitive Which Exotics Are Close to NM or Recently Established? Which ones could I see? What are they? Description? What do they do? Emerald Ash Borer: Asian Invader First Find in US-- 2002, SE Michigan COLORADO Positive for EAB Sept., 2013 Means of Travel? New Movement of Mexico infested firewood Emerald Ash Borer---Buprestidae: Agrilus planipennis Metallic green above & below ½” Larvae feed in phloem D-shaped emergence hole Bushy regrowth, dieback How Do I Know If I Have EAB? Ash tree has limb/trunk die back. Watersprouts on trunk OR limbs. Bark inspection on dead/ dying part has D-shaped emergence holes. (Cut out this sectionCo. Agent! If the bark is peeling, see the tunnels on the wood. Good luck at seeing larvae or adults. Capture larvae/adults for IDCo.

Brown Marmorated Stink Bugs ---Top & Bottom--- Dk brown Punctures Ivory tone underneath BMSB---Damaging Plant Pest • Host range: 60-300 spp. • Recent estimates from PA (fruit crops) – 25% fruit damage (2009)—NJ & PA – PA peach growers lost $15 million, 2010 – U.S. Apple Assn., 2010---Mid-Atlantic growers lost $37 million (18% of crop) More Plant Damage by BMSB • Large size; long enough MPs • Feed on ‘fruit’ (s.l.), nutlets (pecan) • Digestive enzymes certainly damage other hosts • Timing • Opportunity, ‘motive’ (food) ?? Brown Marmorated Stink Bug Inside door on a Pick-up Look up here Common NM Stink Bugs (Hemiptera, Pentatomidae) Euschistus sp. Chinavia Chlorochroa ligata Chlorochroa sayi Brown Stink Bug ‘Green’ ‘Conchuela’ ‘Say’s Stink’ Bug Generalist Generalist Generalist; Common Generalist Sucking MPs, gradual/simple metamorphosis; bodies flattened (think ‘thumb nail’); stink when Disturbed or handled (glands on top of abdomen). Above spp. are plant feeders (there ARE Predatory stink bugs, too). Stink bugs can be serious pests of cotton, sorghum & alfalfa et al. Conchuela has very broad host range---fruit, nuts, veggies, range plants; toxins in saliva cause dimpling in fruit; woody, dry, shrunken fruit; brown, bitter spots on nuts; fruit, seed loss If I Suspect BMSB, Now What? Catch the suspect, put it into a vial of rubbing alcohol--- --OR-- Bag it and freeze it overnight While We’re on Stink Bugs… Bagrada hilaris is in NM, too Adult and Egg Feeding Damage on Crucifer Origin: E & S Africa, S Europe & Asia Established in CA---2008; in AZ, then NM (2010) Host Preferences?
