The Isolation, Genetic Characterisation And
The isolation, genetic characterisation and biological activity of a South African Phthorimaea operculella granulovirus (PhopGV-SA) for the control of the Potato Tuber Moth, Phthorimaea operculella (Zeller) A thesis submitted in fulfilment of the requirements for the degree of MASTER OF SCIENCE At RHODES UNIVERSITY By MICHAEL DAVID JUKES February 2015 i Abstract The potato tuber moth, Phthorimaea operculella (Zeller), is a major pest of potato crops worldwide causing significant damage to both field and stored tubers. The current control method in South Africa involves chemical insecticides, however, there is growing concern on the health and environmental risks of their use. The development of novel biopesticide based control methods may offer a potential solution for the future of insecticides. In this study a baculovirus was successfully isolated from a laboratory population of P. operculella. Transmission electron micrographs revealed granulovirus-like particles. DNA was extracted from recovered occlusion bodies and used for the PCR amplification of the lef-8, lef- 9, granulin and egt genes. Sequence data was obtained and submitted to BLAST identifying the virus as a South African isolate of Phthorimaea operculella granulovirus (PhopGV-SA). Phylogenetic analysis of the lef-8, lef-9 and granulin amino acid sequences grouped the South African isolate with PhopGV-1346. Comparison of egt sequence data identified PhopGV-SA as a type II egt gene. A phylogenetic analysis of egt amino acid sequences grouped all type II genes, including PhopGV-SA, into a separate clade from types I, III, IV and V. These findings suggest that type II may represent the prototype structure for this gene with the evolution of types I, III and IV a result of large internal deletion events and subsequent divergence. -
ENDOCRINE CONTROL of VITELLOGENESIS in BACTERICERA COCKERELLI (HEMIPTERA: TRIOZIDAE), the VECTOR of 'ZEBRA CHIP' a Dissertat
ENDOCRINE CONTROL OF VITELLOGENESIS IN BACTERICERA COCKERELLI (HEMIPTERA: TRIOZIDAE), THE VECTOR OF ‘ZEBRA CHIP’ A Dissertation by FREDDY ANIBAL IBANEZ-CARRASCO Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Cecilia Tamborindeguy Committee Members, Ginger Carney Patricia Pietrantonio Robert Coulson Head of Department, David Ragsdale August 2017 Major Subject: Entomology Copyright 2017 Freddy Ibanez-Carrasco ABSTRACT The potato psyllid, Bactericera cockerelli (Šulc), is a phloem-feeding insect with preference for Solanaceae. This insect species transmits the pathogenic bacteria ‘Candidatus Liberibacter solanacearum’ (Lso) the causative agent of zebra chip, an important disease of commercial potatoes in several countries worldwide. The classification of psyllids among the most dangerous vectors has promoted their study, but still many biological processes need to be investigated. As a first step towards the elucidation of vitellogenesis in B. cockerelli, two candidate vitellogenin transcripts were identified and its expression was analyzed in different life stages. Our results showed that in virgin females, BcVg1-like expression increased up to 5 days old; while mating significantly upregulated its expression in 5- and 7-day-old females and also induced oviposition. BcVg6-like transcript was expressed at similar level between females and males and it was not up-regulated by mating. To elucidate the role of juvenile hormone in B. cockerelli Vgs expression, topical applications of juvenile hormone III (JH III) were performed on virgin females, resulting in an upregulation of BcVg1-like expression and an increase in the number of mature oocytes observed in female reproductive organs. -
Tecia Solanivora Y Symmetrischema Tangolias
Caracterización de la actividad amilásica presente en extractos larvarios de dos polillas plagas de la papa: Tecia solanivora y Symmetrischema tangolias Patricia Mora-Criollo, Andrea Rodríguez-Guerra y Carlos A. Soria Laboratorio de Bioquímica, Escuela de Ciencias Biológicas, Pontificia Universidad Católica del Ecuador, Quito, Ecuador [email protected] Recibido: 11, 05, 2013; aceptado: 09, 10, 2013 RESUMEN.- Las polillas Tecia solanivora y Symmetrischema tangolias (Lepidoptera: Gelechiidae) ocasionan daños significativos a los tubérculos de Solanum tuberosum. El objetivo de este estudio fue aislar y caracterizar bioquímicamente las amilasas presentes en los diferentes estadios larvales de estas polillas. Para efectos comparativos se extrajo las proteínas solubles de estadios larvales criados en el laboratorio para determinar espectrofotométricamente diferencias en la concentración de cada extracto. Se calculó el peso promedio de cada larva: T. solanivora resultó ser más pesada y de ella se obtuvo más proteína soluble en comparación con S. tangolias. La actividad amilásica en los extractos proteicos fue identificada mediante degradación de almidones. Extractos de los estadios IV de ambas polillas, incubados a diferentes intervalos de tiempo, presentaron actividades amilásicas diferentes, aunque resultaron bastante similares cuando se leyeron los resultados de cada extracto tarde a las 72 h. Mediante electroforesis de los extractos proteicos de las larvas de las dos especies, migraron alrededor de 11 bandas proteicas entre 225 y 10 kDa. Entre estas bandas, las amilasas fueron reconocidas en ambas especies y en los 4 estadios como bandas de 50 kDa. La(s) banda(s) probablemente isofórmicas de esta enzima aparecieron muy definidas en los estadios I y II, en contraste con las formas difusas encontradas en los estadios III y IV. -

Wingnut (Juglandaceae)
83 Wingnut (Juglandaceae) as a new generic host for Pityophthorus juglandis (Coleoptera: Curculionidae) and the thousand cankers disease pathogen, Geosmithia morbida (Ascomycota: Hypocreales) Stacy M. Hishinuma, Paul L. Dallara, Mohammad A. Yaghmour, Marcelo M. Zerillo, Corwin M. Parker, Tatiana V. Roubtsova, Tivonne L. Nguyen, Ned A. Tisserat, Richard M. Bostock, Mary L. Flint, Steven J. Seybold1 Abstract—The walnut twig beetle (WTB), Pityophthorus juglandis Blackman (Coleoptera: Curculionidae), vectors a fungus, Geosmithia morbida Kolařík, Freeland, Utley, and Tisserat (Ascomycota: Hypocreales), which colonises and kills the phloem of walnut and butternut trees, Juglans Linnaeus (Juglandaceae). Over the past two decades, this condition, known as thousand cankers disease (TCD), has led to the widespread mortality of Juglans species in the United States of America. Recently the beetle and pathogen were discovered on several Juglans species in northern Italy. Little is known about the extra-generic extent of host acceptability and suitability for the WTB. We report the occurrence of both the WTB and G. morbida in three species of wingnut, Pterocarya fraxinifolia Spach, Pterocarya rhoifolia Siebold and Zuccarini, and Pterocarya stenoptera de Candolle (Juglandaceae) growing in the United States Department of Agriculture-Agricultural Research Service, National Clonal Germplasm Repository collection in northern California (NCGR) and in the Los Angeles County Arboretum and Botanic Garden in southern California, United States of America. In two instances (once in P. stenoptera and once in P. fraxinifolia) teneral (i.e., brood) adult WTB emerged and were collected more than four months after infested branch sections had been collected in the field. Koch’s postulates were satisfied with an isolate of G. -

EPPO Categorization: A1 list more photos... view more categorizations online... EU Categorization: RNQP (Annex IV) EPPO Code: LIBEPS Notes on taxonomy and nomenclature This bacterium was first described from solanaceous plants and psyllids, almost simultaneously in New Zealand and the USA. The name ‘Candidatus Liberibacter psyllaurous (Hansen et al., 2008) was initially proposed, but ‘ Candidatus Liberibacter solanacearum’ (Liefting et al., 2009c) was finally retained as the validly published name. Until now, ‘Ca. L. solanacearum’ has not been cultivated in axenic medium to allow the Koch’s postulates to be verified, hence its ‘Candidatus’ status. The bacterium is genetically diverse and ten haplotypes of ‘Ca. L. solanacearum’ have been described (Nelson et al., 2011, 2013; Teresani et al., 2014; Swisher Grimm and Garczynski, 2019; Haapalainen et al., 2018b; Mauck et al., 2019; Haapalainen et al., 2019; Contreras-Rendón et al., 2019). These haplotypes also differ in their host ranges, psyllid vectors and geographical distributions. In particular, four haplotypes (A, B, F and G) are associated with diseases of potatoes and other solanaceous plants, whereas four others (C, D, E and H-European) are associated with diseases of carrots and other apiaceous crops. Haplotype H European was also described in plants of the family Polygonaceae. -

Discrimination Between Eggs from Stink Bugs Species in Europe Using MALDI-TOF MS
insects Article Discrimination between Eggs from Stink Bugs Species in Europe Using MALDI-TOF MS Michael A. Reeve 1,* and Tim Haye 2 1 CABI, Bakeham Lane, Egham, Surrey TW20 9TY, UK 2 CABI, Rue des Grillons 1, CH-2800 Delémont, Switzerland; [email protected] * Correspondence: [email protected] Simple Summary: Recent globalization of trade and travel has led to the introduction of exotic insects into Europe, including the brown marmorated stink bug (Halyomorpha halys)—a highly polyphagous pest with more than 200 host plants, including many agricultural crops. Unfortunately, farmers and crop-protection advisers finding egg masses of stink bugs during crop scouting frequently struggle to identify correctly the species based on their egg masses, and easily confuse eggs of the invasive H. halys with those of other (native) species. To this end, we have investigated using matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) for rapid, fieldwork-compatible, and low-reagent-cost discrimination between the eggs of native and exotic stink bugs. Abstract: In the current paper, we used a method based on stink bug egg-protein immobilization on filter paper by drying, followed by post-(storage and shipping) extraction in acidified acetonitrile containing matrix, to discriminate between nine different species using MALDI-TOF MS. We obtained 87 correct species-identifications in 87 blind tests using this method. With further processing of the unblinded data, the highest average Bruker score for each tested species was that of the cognate Citation: Reeve, M.A.; Haye, T. reference species, and the observed differences in average Bruker scores were generally large and the Discrimination between Eggs from errors small except for Capocoris fuscispinus, Dolycoris baccarum, and Graphosoma italicum, where the Stink Bugs Species in Europe Using average scores were lower and the errors higher relative to the remaining comparisons.
