(Pentatomidae) DISSERTATION Presented
Genome Evolution During Development of Symbiosis in Extracellular Mutualists of Stink Bugs (Pentatomidae) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Alejandro Otero-Bravo Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2020 Dissertation Committee: Zakee L. Sabree, Advisor Rachelle Adams Norman Johnson Laura Kubatko Copyrighted by Alejandro Otero-Bravo 2020 Abstract Nutritional symbioses between bacteria and insects are prevalent, diverse, and have allowed insects to expand their feeding strategies and niches. It has been well characterized that long-term insect-bacterial mutualisms cause genome reduction resulting in extremely small genomes, some even approaching sizes more similar to organelles than bacteria. While several symbioses have been described, each provides a limited view of a single or few stages of the process of reduction and the minority of these are of extracellular symbionts. This dissertation aims to address the knowledge gap in the genome evolution of extracellular insect symbionts using the stink bug – Pantoea system. Specifically, how do these symbionts genomes evolve and differ from their free- living or intracellular counterparts? In the introduction, we review the literature on extracellular symbionts of stink bugs and explore the characteristics of this system that make it valuable for the study of symbiosis. We find that stink bug symbiont genomes are very valuable for the study of genome evolution due not only to their biphasic lifestyle, but also to the degree of coevolution with their hosts. i In Chapter 1 we investigate one of the traits associated with genome reduction, high mutation rates, for Candidatus ‘Pantoea carbekii’ the symbiont of the economically important pest insect Halyomorpha halys, the brown marmorated stink bug, and evaluate its potential for elucidating host distribution, an analysis which has been successfully used with other intracellular symbionts. -
A Review of Sampling and Monitoring Methods for Beneficial Arthropods
insects Review A Review of Sampling and Monitoring Methods for Beneficial Arthropods in Agroecosystems Kenneth W. McCravy Department of Biological Sciences, Western Illinois University, 1 University Circle, Macomb, IL 61455, USA; [email protected]; Tel.: +1-309-298-2160 Received: 12 September 2018; Accepted: 19 November 2018; Published: 23 November 2018 Abstract: Beneficial arthropods provide many important ecosystem services. In agroecosystems, pollination and control of crop pests provide benefits worth billions of dollars annually. Effective sampling and monitoring of these beneficial arthropods is essential for ensuring their short- and long-term viability and effectiveness. There are numerous methods available for sampling beneficial arthropods in a variety of habitats, and these methods can vary in efficiency and effectiveness. In this paper I review active and passive sampling methods for non-Apis bees and arthropod natural enemies of agricultural pests, including methods for sampling flying insects, arthropods on vegetation and in soil and litter environments, and estimation of predation and parasitism rates. Sample sizes, lethal sampling, and the potential usefulness of bycatch are also discussed. Keywords: sampling methodology; bee monitoring; beneficial arthropods; natural enemy monitoring; vane traps; Malaise traps; bowl traps; pitfall traps; insect netting; epigeic arthropod sampling 1. Introduction To sustainably use the Earth’s resources for our benefit, it is essential that we understand the ecology of human-altered systems and the organisms that inhabit them. Agroecosystems include agricultural activities plus living and nonliving components that interact with these activities in a variety of ways. Beneficial arthropods, such as pollinators of crops and natural enemies of arthropod pests and weeds, play important roles in the economic and ecological success of agroecosystems. -

Bird Predation on Periodical Cicadas in Ozark Forests: Ecological Release for Other Canopy Arthropods?
Studies in Avian Biology No. 13:369-374, 1990. BIRD PREDATION ON PERIODICAL CICADAS IN OZARK FORESTS: ECOLOGICAL RELEASE FOR OTHER CANOPY ARTHROPODS? FREDERICK M. STEPHEN, GERALD W. WALLIS, AND KIMBERLY G. SMITH Abstract. Population dynamics of canopy arthropods were monitored in two upland forests in the Arkansas Ozarks during spring and summer of 1984-1986 to test whether the emergence of adult 13-year periodical cicadas on one site during late spring in 1985 would disrupt normal patterns of bird predation on canopy arthropods, resulting in ecological release for those prey populations. Canopy arthropods on foliage of oak, hickory, and eastern redcedar were sampled weekly beginning in June 1984, and April 1985 and 1986, and continuing through August in all years. We classed arthropods into four broad guilds based on foraging mode (chewers, suckers, spiders, and lepidopterous larvae) and expressed densities as number of individuals per kg of foliage sampled. Two-way analysis of variance revealed no significant treatment effects for densities of chewing, sucking, or lepidopteran larval guilds. A significant interaction of mean density between sites among years was detected for the spider guild, but not when cicadas were present, indicating that ecological release did not occur. We trace the development of the notion that bird populations are capable of affecting prey population levels, and discuss those ideas in light of our results, which suggest that birds have little impact upon their arthropod prey in Ozark forests.

Richman2 Introduction Distribution The predatory stink bug, Euthyrhynchus floridanus (Lin- Euthyrhynchus floridanus is primarily a Neotropical species naeus) (Figure 1), is considered a beneficial insect because that ranges within the southeastern quarter of the United most of its prey consists of plant-damaging bugs, beetles, States. and caterpillars. It seldom plays a major role in the natural control of insects in Florida, but its prey includes a number Description of economically important species. Adults The length of males is approximately 12 mm, with a head width of 2.3 mm and a humeral width of 6.4 mm. The length of females is 12 to 17 mm, with a head width of 2.4 mm and a humeral width of 7.2 mm. Euthyrhynchus floridanus (Figure 2) normally can be distinguished from all other stink bugs in the southeastern United States by a red- dish spot at each corner of the scutellum outlined against a blue-black to purplish-brown ground color. Variations occur that might cause confusion with somewhat similar stink bugs in several genera, such as Stiretrus, Oplomus, and Perillus, but these other bugs have obtuse humeri, or at least lack the distinct humeral spine that is present in adults of Euthyrhynchus. In addition, species of these genera Figure 1.

Phylogenetic Relationships of Tachinid Flies in Subfamily Exoristinae Tachinidae: Diptera) Based on 28S Rdna and Elongation Factor-1A
Systematic Entomology *2002) 27,409±435 Phylogenetic relationships of tachinid flies in subfamily Exoristinae Tachinidae: Diptera) based on 28S rDNA and elongation factor-1a JOHN O. STIREMAN III Department of Ecology and Evolutionary Biology,University of Arizona,Tucson,U.S.A. Abstract. The phylogenetic relationships within the largest subfamily of Tachi- nidae,Exoristinae,were explored using nucleotide sequences of two genes *EF-1 a and 28S rDNA). A total of fifty-five and forty-three taxa were represented in the analyses for each gene,respectively,representing forty-three genera. Neighbour joining,parsimony and maximum likelihood inference methods were employed to reconstruct phylogenetic relationships in separate analyses of each gene,and parsimony was used to analyse the combined dataset. Although certain taxa were highly mobile,phylogenetic reconstructions generally supported recent clas- sification schemes based on reproductive habits and genitalia. Generally,the monophyly of Tachinidae and Exoristinae was supported. Tribes Winthemiini, Exoristini and Blondeliini were repeatedly constructed as monophyletic groups, with the former two clades often occupying a basal position among Exoristinae. Goniini and Eryciini generally clustered together as a derived clade within Exoristinae; however,they were never reconstructed as two distinct clades. These results suggest that the possession of unembryonated eggs is plesiomorphic within the subfamily and that there may have been multiple transitions between micro- type and macrotype egg forms. Introduction 1987; Williams et al.,1990; Eggleton & Belshaw,1993), and the wide variety of mechanisms by which they attack Tachinidae is generally regarded as a relatively recent, them *O'Hara,1985). These oviposition strategies include actively radiating clade of parasitic flies *Crosskey,1976). -
The Isolation and Identification of Pathogenic Fungi from Tessaratoma Papillosa Drury (Hemiptera: Tessaratomidae)
The isolation and identification of pathogenic fungi from Tessaratoma papillosa Drury (Hemiptera: Tessaratomidae) Xiang Meng1, Junjie Hu2 and Gecheng Ouyang1 1 Guangdong Key Laboratory of Animal Conservation and Resource Utilization, Guangdong Public Laboratory of Wild Animal Conservation and Utilization, Guangdong Institute of Applied Biological Resources, Guangzhou, Guangdong, China 2 College of Life Science, Guangzhou University, Guangzhou, Guangdong, China ABSTRACT Background. Litchi stink-bug, Tessaratoma papillosa Drury (Hemiptera: Tessarato- midae), is one of the most widespread and destructive pest species on Litchi chinensis Sonn and Dimocarpus longan Lour in Southern China. Inappropriate use of chemical pesticides has resulted in serious environmental problems and food pollution. Generating an improved Integrated Pest Management (IPM) strategy for litchi stink- bug in orchard farming requires development of an effective biological control agent. Entomopathogenic fungi are regarded as a vital ecological factor in the suppression of pest populations under field conditions. With few effective fungi and pathogenic strains available to control litchi stink-bug, exploration of natural resources for promising entomopathogenic fungi is warranted. Methods & Results. In this study, two pathogenic fungi were isolated from cadavers of adult T. papillosa. They were identified as Paecilomyces lilacinus and Beauveria bassiana by morphological identification and rDNA-ITS homogeneous analysis. Infection of T. papillosa with B. bassiana and P. lilacinus occurred initially from the antennae, metameres, and inter-segmental membranes. Biological tests showed that the two entomopathogenic fungi induced high mortality in 2nd and 5th instar nymphs of Submitted 1 March 2017 nd Accepted 13 September 2017 T. papillosa. B. bassiana was highly virulent on 2 instar nymphs of T. -

Climate-Related Transboundary Pests and Diseases
HLC/08/BAK/4 CLIMATE-RELATED TRANSBOUNDARY PESTS AND DISEASES TECHNICAL BACKGROUND DOCUMENT FROM THE EXPERT CONSULTATION HELD ON 25 TO 27 FEBRUARY 2008 FAO, ROME CLIMATE CHANGE AND PEST DISEASES The movement of plant pests, animal diseases and invasive alien aquatic organisms across physical and political boundaries threatens food security and creates a global public concern across all countries and all regions. Countries allocate large resources to limit the spread and control of transboundary pests and diseases 1 such as avian influenza, foot-and-mouth disease and locust. They also adapt animal and plant health services and activities and cooperate regionally and globally for prevention, early warning and control. There is clear evidence that climate change is altering the distribution, incidence and intensity of animal and plant pests and diseases such as Bluetongue, a sheep disease that is moving north into more temperate zones of Europe. Cannon (see Annex 1) found examples of plant pests whose distribution is shifting in the United Kingdom and other parts of Europe, most likely due to climatic factors. For example, migrant moths of the Old World bollworm ( Helicoverpa armigera) had a phenomenal increase in the United Kingdom from 1969-2004 and there have been outbreaks at the northern edge of its range in Europe; cottony cushion scale ( Icerya purchasi) populations appear to be spreading northwards perhaps as a consequence of global warming; and cottony camellia scale ( Pulvinaria – Chloropulvinaria – floccifera) has become much more common in the United Kingdom, extending its range northwards in England and increasing its host range in the last decade or so, which is almost certainly in response to climate change. -
