Changes in Arthropod Abundance and Diversity with Invasive
CHANGES IN ARTHROPOD ABUNDANCE AND DIVERSITY WITH INVASIVE GRASSES A Thesis by ERIN E.

Henke, Ph.D. (Chair of Department) _________________________________ Ambrose Anoruo, Ph.D. (Associate VP for Research & Dean, College of Graduate Studies) August 2011 ABSTRACT Changes in Arthropod Abundance and Diversity with Invasive Grasses (August 2011) Erin E. Cord, B.S., University Of Delaware Chairman of Committee: Dr. Andrea R. Litt Invasive grasses can alter plant communities and can potentially affect arthropods due to specialized relationships with certain plants as food resources and reproduction sites. Kleberg bluestem (Dichanthium annulatum) is a non-native grass and tanglehead (Heteropogon contortus) is native to the United States, but recently has become dominant in south Texas. I sought to: 1) quantify changes in plant and arthropod communities in invasive grasses compared to native grasses, and 2) determine if grass origin would alter effects. I sampled vegetation and arthropods on 90 grass patches in July and September 2009 and 2010 on the King Ranch in southern Texas. Arthropod communities in invasive grasses were less diverse and abundant, compared to native grasses; I also documented differences in presence and abundance of certain orders and families. -

Linking Morphological and Molecular Taxonomy for the Identification of Poultry House, Soil, and Nest Dwelling Mites in the Weste
www.nature.com/scientificreports OPEN Linking morphological and molecular taxonomy for the identifcation of poultry house, Received: 27 October 2018 Accepted: 20 March 2019 soil, and nest dwelling mites in the Published: xx xx xxxx Western Palearctic Monica R. Young 1, María L. Moraza2, Eddie Ueckermann3, Dieter Heylen4,5, Lisa F. Baardsen6, Jose Francisco Lima-Barbero 7,8, Shira Gal9, Efrat Gavish-Regev 10, Yuval Gottlieb11, Lise Roy 12, Eitan Recht13, Marine El Adouzi12 & Eric Palevsky9 Because of its ability to expedite specimen identifcation and species delineation, the barcode index number (BIN) system presents a powerful tool to characterize hyperdiverse invertebrate groups such as the Acari (mites). However, the congruence between BINs and morphologically recognized species has seen limited testing in this taxon. We therefore apply this method towards the development of a barcode reference library for soil, poultry litter, and nest dwelling mites in the Western Palearctic. Through analysis of over 600 specimens, we provide DNA barcode coverage for 35 described species and 70 molecular taxonomic units (BINs). Nearly 80% of the species were accurately identifed through this method, but just 60% perfectly matched (1:1) with BINs. High intraspecifc divergences were found in 34% of the species examined and likely refect cryptic diversity, highlighting the need for revision in these taxa. These fndings provide a valuable resource for integrative pest management, but also highlight the importance of integrating morphological and molecular methods for fne-scale taxonomic resolution in poorly-known invertebrate lineages. DNA barcoding1 alleviates many of the challenges associated with morphological specimen identifcation by comparing short, standardized fragments of DNA – typically 648 bp of the cytochrome c oxidase I (COI) gene for animals – to a well-curated reference library. -
Distribution, Biology, Ecology and Control of the Psyllid Diaphorina Citri Kuwayama, a Major Pest of Citrus: a Status Report for China
International Journal of Pest Management, October – December 2006; 52(4): 343 – 352 Distribution, biology, ecology and control of the psyllid Diaphorina citri Kuwayama, a major pest of citrus: A status report for China YUEPING YANG1, MINGDU HUANG1, G.

Its status derives, not from the damage it causes, but from its role as the only known vector in China of huanglongbing, a phloem- limited bacterial disease of international importance. The disease can devastate orchards within a few years of planting. It also poses a major threat to endangered indigenous citrus germplasm in Asia and Australasia. The distribution, biology, ecology and control of the psyllid in China are reviewed in these contexts. Constraints and challenges related to control of the vector in China are discussed.

We hypothesized that organic matter such as straw mulch also favors the maintenance of predatory mites which visit strawberry plants at nighttime. We compared mite diversity in cereal straw exposed for different periods in strawberry fields and evaluated their possible migration to plants in two experiments with potted plants in 2019. An ‘Early season’ experiment compared no mulching (T1), oat straw mulch exposed in field since 2018 (T2), or 2017 (T3), while a ‘Mid-season’ experiment compared no mulching (T1), barley straw mulch from 2018 (T2), or a mix from 2017 and 2018 (T3). -

JULY 2019 EDITION: ABN 2019 - 4 AFRICAN (MAY AND JUNE 2019) THE LEPIDOPTERISTS’ BUTTERFLY SOCIETY OF AFRICA NEWS LATEST NEWS Welcome to July’s newsletter! Winter has arrived on the Highveld and not much is flying at the moment. This may be a positive development, as last season there appeared to be little variation in butterfly numbers between the winter and summer months. KwaZulu-Natal was good in May, but numbers seem to be tailing off now. A reminder that this year’s LepSoc Africa Conference will be held in Knysna on Sat 16 and Sun 17 November. Please contact Dave Edge ([email protected]) to confirm your attendance. In addition to the Conference, Mon 18 Nov has been set aside as a public day, where we intend to search for the Brenton Blue (Orachrysops niobe); the Brenton Blue Trust have put up a R20 000 reward, payable to the first person who rediscovers this critically endangered butterfly. Orachrysops niobe Subject to demand, LSA intend to host a two-day field trip to the Steve Woodhall Kammannassie, camping at Mannetjiesberg on the night of Fri 15 November. Corrections Steve Collins picked up a couple of errors in March’s newsletter: • Dave Richard’s photo of a Charaxes from Rwanda is Charaxes alticola, which I’d misidentified as Charaxes ansorgei ruandana. • The first butterfly in the Butterfly Identification plate (Heteropsis) was titled Heteropsis exocellata, but it is in fact a dry-season Heteropsis pauper. 1 Storage of Lepidoptera collections (Jeremy Dobson) There is an urgent need for LepSoc Africa to find a storage facility for lepidoptera specimens. -

Amber! Conrad C
AMBER! CONRAD C. LABANDEIRA! Department of Paleobiology, National Museum of Natural History, Smithsonian Institution Washington, D.C. 20013 USA ˂[email protected]! ˃ and! Department of Entomology, University of Maryland, College Park, MD 20742 USA ABSTRACT.—The amber fossil record provides a distinctive, 320-million-year-old taphonomic mode documenting gymnosperm, and later, angiosperm, resin-producing taxa. Resins and their subfossil (copal) and fossilized (amber) equivalents are categorized into five classes of terpenoid, phenols, and other compounds, attributed to extant family-level taxa. Copious resin accumulations commencing during the early Cretaceous are explained by two hypotheses: 1) abundant resin production as a byproduct of plant secondary metabolism, and 2) induced and constitutive host defenses for warding off insect pest and pathogen attack through profuse resin production. Forestry research and fossil wood-boring damage support a causal relationship between resin production and pest attack. Five stages characterize taphonomic conversion of resin to amber: 1) Resin flows initially caused by biotic or abiotic plant-host trauma, then resin flowage results from sap pressure, resin viscosity, solar radiation, and fluctuating temperature; 2) entrapment of live and dead organisms, resulting in 3) entombment of organisms; then 4) movement of resin clumps to 5) a deposition site. This fivefold diagenetic process of amberization results in resin→copal→amber transformation from internal biological and chemical processes and external geological forces. Four phases characterize the amber record: a late Paleozoic Phase 1 begins resin production by cordaites and medullosans. A pre-mid-Cretaceous Mesozoic Phase 2 provides increased but still sparse accumulations of gymnosperm amber. Phase 3 begins in the mid-early Cretaceous with prolific amber accumulation likely caused by biotic effects of an associated fauna of sawflies, beetles, and pathogens.
