The Ecology of Insect Mediated Transmission of the Fire Blight Pathogen, Erwinia Amylovora, by Orchard Dwelling Dipterans
THE ECOLOGY OF INSECT MEDIATED TRANSMISSION OF THE FIRE BLIGHT PATHOGEN, ERWINIA AMYLOVORA, BY ORCHARD DWELLING DIPTERANS A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Matthew T. Boucher August 2020 © 2020 Matthew T. Boucher THE ECOLOGY OF INSECT MEDIATED TRANSMISSION OF THE FIRE BLIGHT PATHOGEN, ERWINIA AMYLOVORA, BY ORCHARD DWELLING DIPTERANS Matthew T. Boucher, Ph. D. Cornell University 2020 Fire blight, caused by the bacterial pathogen Erwinia amylovora, is a devastating disease of pome fruit with worldwide distribution. The disease gets its name from the scorched appearance of diseased tissue and infects all tissue types of pomaceous fruit. Tissue in the early stages of infection exude a bacterial ooze containing the bacteria in a polysaccharide matrix, which acts as primary and secondary inoculum. Insects have been implicated in the transmission of E. amylovora since the pathogen was first discovered, with various mechanisms for insect mediated transmission proposed. The goal of this research was to further define the role of insects in transmission of E. amylovora by identifying its most important potential vectors in New York State and advancing our knowledge of the ecology of transmission by insects. In chapter 1, we describe field surveys used to identify key insect vectors over the course of a growing season, showing that while pollinating hymenopterans historically received attention as springtime disease disseminators, dipterans have an understudied and potentially outsized role in transmission throughout the entire season. Various families of Diptera were observed feeding on bacterial ooze and could shed bacteria for at least six days following an acquisition event from ooze. -
Oystershell Scale
Quick IPM Facts W289-R Oystershell Scale Lepidosaphes ulmi Host Plants Oystershell scale attacks 85 plant genera from 33 plant families including: • Birch Mother scale • Boxwood • Crabapple • Dogwood • Elm Dead crawlers • Hawthorn • Lilac Live crawlers • Linden Description • Magnolia • Maple Oystershell scale gets its name from the oystershell appearance • Ornamental cherry of its waxy coating. This armored scale insect has two forms: the • brown/apple form and the lilac form. It is an economically important pest Pear in nurseries, landscapes and orchards. The oystershell scale is mainly a • Redbud northern species and is commonly found in most states except those • Smoketree bordering Mexico and the Gulf of Mexico. • Viburnum • Willow Life Cycle Oystershell scale overwinter as white eggs protected beneath the waxy covering of the adult female scale. The crawlers hatch in the spring and then move a small distance from their mother before settling on the bark to feed (live and dead crawlers and adult scale are circled above). Crawlers form their own protective wax coating about a week later. Because of this narrow window, coordinating spray applications with crawler emergence is very important for achieving good control. Depending on the host and geographic location, oystershell scale may produce one to two generations per year. Monitoring Adult scale Look on the bark for the oystershell-shaped scale covers. Check beneath the scale covers for healthy, white eggs in the spring to estimate the effectiveness of previous control strategies. In late May, begin scouting for crawlers from the first-generation egg hatch, then again in late July when eggs from the second generation hatch. -
Aphis Spiraecola
Rapid Pest Risk Analysis (PRA) for Aphis spiraecola STAGE 1: INITIATION 1. What is the name of the pest? Aphis spiraecola Patch (Hemiptera, Aphididae) – Spiraea aphid (also Green citrus aphid). Synonyms: many, due to historic confusion over its identity; most common is Aphis citricola van der Goot (see CABI, 2013). 2. What initiated this rapid PRA? The UK Plant Health Risk Register identified the need to update the first UK PRA (MacLeod, 2000), taking into account recent information on hosts, impacts, vectored pathogens and UK status. 3. What is the PRA area? The PRA area is the United Kingdom of Great Britain and Northern Ireland. STAGE 2: RISK ASSESSMENT 4. What is the pest’s status in the EC Plant Health Directive (Council Directive 2000/29/EC1) and in the lists of EPPO2? Aphis spiraecola is not listed in the EC Plant Health Directive, not recommended for regulation as a quarantine pest by EPPO and it is not on the EPPO Alert List. 5. What is the pest’s current geographical distribution? Aphis spiraecola probably originates in the Far East. It is now very widespread around the world in temperate and tropical regions, occurring across every continent except Antarctica (CABI, 2013). In Europe, A. spiraecola is found around the Mediterranean, with a patchy Balkan distribution and it is absent from Scandinavia and the Baltic states. It is stated as present in: Spain, Portugal, France, Switzerland, Italy, Slovenia, Croatia, Serbia, Hungary, Bulgaria, Greece, Cyprus, Malta, and Russia (west of the Urals) (CABI 2013). It is not confirmed as being established in the Netherlands, either outdoors or under protection. -

Abstract The cabbage looper moth (CLM), Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) is an agricultural pest that has developed resistance to many frequently used insecticides, so alternative methods are required to reduce greenhouse CLM populations. Host plant volatile organic chemicals (VOCs) are used by female CLMs as cues for host location and oviposition. I hypothesized that changes in host plant VOC production, through genetic modification, could alter host location behaviour by CLMs. These changes in VOCs have potential to give rise to highly attractive transgenic trap crops. -

Using a meta- 8 analysis approach, we aimed to advance understanding of how increased drought 9 incidence will affect this ecologically and economically important insect group, and to 10 characterise the underlying mechanisms. 11 Location 12 Global. 13 Time period 14 1958–2020. 15 Major taxa studied 16 Aphids. 17 Methods 18 We used qualitative and quantitative synthesis techniques to determine whether 19 drought stress has a negative, positive, or null effect on aphid fitness. We examined 20 these effects in relation to 1) aphid biology, 2) the aphid-plant. species combination. 21 We compiled two datasets: 1) a “global” dataset (n = 55 from 55 published studies) 22 comprising one pooled effect size per study, and 2) an “expanded” dataset (n = 93) 23 containing multiple datapoints per study, separated into different measures of aphid 24 fitness but pooled across aphid-plant combinations. Where reported, we extracted 25 data on the effect of drought on plant vigour, and plant tissue concentrations of 26 nutrients and defensive compounds, to capture the potential causes of aphid 27 responses. -
