Advances in Taxonomy and Systematics of Platygastroidea (Hymenoptera)
Advances in Taxonomy and Systematics of Platygastroidea (Hymenoptera) Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Charuwat Taekul, M.S. Graduate Program in Evolution, Ecology, and Organismal Biology ***** The Ohio State University 2012 Dissertation Committee: Dr. Norman F. Johnson, Advisor Dr. Johannes S. H. Klompen Dr. John V. Freudenstein Dr. Marymegan Daly Copyright by Charuwat Taekul 2012 ABSTRACT Wasps, Ants, Bees, and Sawflies one of the most familiar and important insects, are scientifically categorized in the order Hymenoptera. Parasitoid Hymenoptera display some of the most advanced biology of the order. Platygastroidea, one of the significant groups of parasitoid wasps, attacks host eggs more than 7 insect orders. Despite its success and importance, an understanding of this group is still unclear. I present here the world systematic revisions of two genera in Platygastroidea: Platyscelio Kieffer and Oxyteleia Kieffer, as well as introduce the first comprehensive molecular study of the most important subfamily in platygastroids as biological control benefit, Telenominae. For the systematic study of two Old World genera, I address the taxonomic history of the genus, identification key to species, as well as review the existing concepts and propose descriptive new species. Four new species of Platyscelio are discovered from South Africa, Western Australia, Botswana and Zimbabwe. Four species are considered to be junior synonyms of P. pulchricornis. Fron nine valid species of Oxyteleia, the new species are discovered throughout Indo-Malayan and Australasian regions in total of twenty-seven species. The genus Merriwa Dodd, 1920 is considered to be a new synonym. -

However, use of insecticides, whether biological or synthetic compounds, is Pesticide often detrimental to natural enemies. By definition toxic to insects, insecticides may cause direct mortality of Physiological selectivity natural enemies, reduce food resources (prey/host), or disrupt behavioral and biological processes. Therefore, Ecological selectivity choosing a selective insecticide or selectively applying are important decisions for conserving natural enemies if Soybean insecticide is required. In situations where both insecticide and natural enemy do not share the same target pest, Cotton an additive outcome is expected and CBC can minimize pest outbreaks and resurgence. Given that new, selective insecticides are usually more expensive than older ones, using the former typically adds cost per treated area. Therefore, choosing a selective insecticide becomes a matter of benefits and costs, considering the cost compared to other available treatments and potential pest problems. Beyond the differential toxicity of selective in- secticides to natural enemy and target pest species, some human decisions may produce insecticide selectivity, including application of minimal effective rates, and spatiotemporal separation of nonselective insecticides and natural enemies. -
Egg Parasitoids of Stink Bugs (Hemiptera: Coreidae and Pentatomidae) on Soybean and Cowpea in Brazil Antonio De Almeida Paz-Neto1, Ranyse B
Egg parasitoids of stink bugs (Hemiptera: Coreidae and Pentatomidae) on soybean and cowpea in Brazil Antonio de Almeida Paz-Neto1, Ranyse B. Querino2,*, and Cecilia B. Margaría3 Abstract Parasitoids naturally attacking stink bug (Hemiptera: Coreidae and Pentatomidae) eggs and interactions with their hosts were recorded on soybean (Glycine max [L.] Merril; Fabales: Fabaceae) and cowpea (Vigna unguiculata [L.] Walp.; Fabales: Fabaceae) host plants in Brazil. Egg masses of stink bugs collected from plant structures were observed daily until emergence of either parasitoids or bugs. Stink bugs were parasitized by 8 species of egg parasitoids: Trissolcus urichi Crawford, Trissolcus teretis Johnson, Trissolcus bodkini Crawford, Telenomus podisi Ashmead, Phanuropsis semiflaviven- tris Girault (Hymenoptera: Platygastridae), Neorileya flavipes Ashmead (Hymenoptera: Eurytomidae), Ooencyrtus anasae (Ashmead) (Hymenoptera: Encyrtidae), andAnastatus sp. (Hymenoptera: Eupelmidae). Trissolcus urichi, Te. podisi, O. anasae, and N. flavipes parasitized eggs of 2 or more spe- cies of stink bugs, andTr. urichi and Te. podisi were the most generalist. Phanuropsis semiflaviventris, Tr. teretis, Tr. bodkini, and Anastatus sp. showed specialist behavior, because each of them parasitized only 1 species of stink bug.

The first meeting was in Hawaii – USA during January 2002, followed by the Davos - Switzerland meeting during September 2005, and the Christchurch – New Zealand meeting during February 2009. The goal of these symposia is to create a forum where biological control researchers and practitioners can meet and exchange information, to promote discussions of up to date issues affecting biological control, particularly pertaining to the use of parasitoids and predators as biological control agents. -
Telenomus Podisi: One Species, Or More?
Telenomus podisi: one species, or more? THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Kelsey Rae Bowers Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2015 Master's Examination Committee: Dr. Norman F. Johnson, advisor Dr. Marymegan Daly Dr. John V. Freudenstein Copyright by Kelsey Rae Bowers 2015 Abstract Parasitoid wasps are a collection of hymenopterans whose larvae feed on the body of a host, eventually killing it (Godfray 1994). The parasitoid wasp Telenomus podisi Ashmead (Hymenoptera: Platygastridae, Telenominae) parasitizes the eggs of both phytophagous and predaceous pentatomids, including a number of important agricultural pests (e.g., Temerak and Whitcomb 1984, Schaefer and Panizzi 2000). Comparisons of strains from Maryland and Brazil has begun to raise questions as to whether T. podisi is a single species (Borges et al. 2003). This study considers populations of T. podisi throughout the species range to determine if there is evidence to support the hypothesis of T. podisi as more than one species. Cytochrome oxidase I is sequenced for 50 specimens of T. podisi from Saskatchewan, Ohio, Tennessee, Arkansas, Nebraska, Panama, Brazil and the Dominican Republic, along with one specimen each of Telenomus sechellensis Kieffer, Telenomus grenadensis Ashmead, and Trissolcus basalis Wollaston. A number of species delimitation methods are considered, including DNA barcoding with pairwise distances, the General Mixed Yule Coalescent Model (GMYC) and Poisson Tree Process Model (PTP) (Fujisawa and Barraclough 2013, Zhang et al. 2013). DNA barcoding attempts to detect the transition between interspecific and intraspecific variation by a gap in the distribution of genetic distances, and this gap is clear in the histogram of p- distances (Hebert et al., 2004). -
