BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Larvae ‘Mine’ Ash Phloem/Cambium Tissues Die, Bark Dries and Peels Off
Adults are difficult to monitor; No good way to detect early Can fly 1-3 miles? More? Infestations--’girdling’ a trap tree?

BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Leah Bauer, bugwood.org Impacts of EAB Visual, Property Values, Costs of Treatment, Removal*
Major expense for cities. Add suburbs and $$$.
That’s YOUR tax dollars!
Toledo, OH neighborhood: ‘Before’ = June, 2006; ‘After’ = August, 2009
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu More Impacts From EAB Infestation State & federal quarantines
Costs of surveys, tree marking, treatment or removal on city/county land (tax $$)
Nurseries---no sales of ash trees ---production fields worthless
Public Debates---treat or not? $$$, gamble
Loss of shade trees, ash can represent 20% or more of urban forest
Loss of shade, air conditioners work harder
Water consumption increases---$$$
No ash wood tool handles, baseball bats, etc.
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu White Fringetree, Chionanthus virginicus (Oleaceae) ---EAB verified on it in Ohio---
A shrub-tree native to the Southeastern US
Increasingly popular? In Midwest, elsewhere
Delicate blooms = name
Are there members of the Oleaceae native to NM or the Southwest that could be at risk of EAB infestation?
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Other Oleaceae in NM: Could These Host EAB? EAB has targeted green, white & velvet ash in US
Forestiera pubescens: NM Olive Fraxinus lowellii, Lowell Ash *Fraxinus spp. = trees *Forestiera = shrub Menodora = perennial herb ___ *Possible to Very Likely Hosts? Fraxinus velutina
BE BOLD. Shape the Future. Velvet Ash New Mexico State University aces.nmsu.edu Menodora scabra Back to Colorado---Where is EAB? Boulder Co., 5 communities since 2013
Fort Collins is NE of here (41mi as crows fly)
16mi
‘Gunbarrel’? YIKES!!!
Flights of 1-3 miles? Riding inside firewood? Adults hitchhiking on ? Denver is SE of here (27mi from Boulder)
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Is EAB a Knock-out Punch for Ash in New Mexico?

Redheaded ash borer
Lilac-Ash Borer Cosmetic to Killer? Ash gall mites
Ash twig beetle Ash leaf-curl aphid
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Ash Whitefly, Siphoninus phillyreae

Hosts in NM: ash, pomegranate, lilac, apple, crabapple, pear, Bradford pear, chitalpa, crape myrtle, hawthorne, quince, pyracantha
Copious honeydew, leaf loss; immatures ringed by stalks with waxy exudate; late summer
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Ash Borers & Lilac-Ash Borer

BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Twig Beetles on Ash Trees Coleoptera, Curculionidae, Hylesinus spp. 3mm
Twig damage is cumulative; canopy reduced Dead twigs ‘cage’ struggling ‘sprouts’
These pests are already widely distributed in NM.
Adults mine buds, twigs; larval ‘breathing & escape holes’
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Remember the MG & the Dying Tree Story?
D-shaped His Evidence-Photographs & Samples! emergence holes!
Skinny, shiny beetles stuck died under peeling bark!
Peeling bark; larval tunnels criss-cross Tree dying from top down! vascular system! Water sprouts at base!

Graeme Davis, Lynda Garvin---CES Connie Jones, Bill Segura--NMDA
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu RESULTS! Jennifer Shaughney, NMSU Arthropod Museum Host tree was a ‘Honey Locust’
Insect WAS Agrilus difficilis (attacks honey locust) D What A. difficilis does to honey locust mirrors what EAB does to ashkills it See?
Previous record of A. difficilis in NM (Nelson, et al. 2008.) More difficilis found in honey locust since 7/2015 in ABQ, Santa Fe, Farmington & Portales
Sutherland’s ID confirmed by USDA-APHIS,PPQ-James Zablotny
BE BOLD. Shape the Future. Congrats from USDA, APHIS, PPQ- Washington DC_ New Mexico State University aces.nmsu.edu Best Ever Field Trip
EAB: bell-shaped segments Honey Locust: rounded segments
VS
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu My Challenge to YOU!!! Find, Document & Report Other Honey Locusts with Agrilus difficilis
Probably travels in/on trees in nursery trade; possible movement in infested honey locust firewood
It’s likely where you work, too!
Look AGAIN at dead honey locust When you’re removing one…..
BE BOLD. Shape the Future. New Mexico State University aces.nmsu.edu Oak Trees & Kermesid Scale Insects in NM
Damage is cumulative. Twigs, then branches die---whole tree! Mature females Adult male Female & eggs
Euclemensia schwarziella (Lepidoptera, Cosmopterygidae), AZ & TX. Larvae are internal parasitoids of Allokermes scales! Are they in NM?

Mystery Wasp---abt 3-4mm long
I suggested Eurytoma tumoris---this or something similar mentioned in Western Forest Insects (Furniss & Carolin)
So far, no alternative ID
Other tiny wasps in this family are parasitoids
This one is a plant pest?
No insecticides labeled specifically for it
