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. -
Candidatus Liberibacter Solanacearum'
EPPO Datasheet: 'Candidatus Liberibacter solanacearum' Last updated: 2020-04-22 Only Solanaceae haplotypes of ‘Candidatus Liberibacter solanacearum’ are included in the EPPO A1 List. IDENTITY Preferred name: 'Candidatus Liberibacter solanacearum' Authority: Liefting, Perez-Egusquiza & Clover Taxonomic position: Bacteria: Proteobacteria: Alphaproteobacteria: Rhizobiales: Phyllobacteriaceae Other scientific names: Liberibacter psyllaurous Hansen,Trumble, Stouthamer & Paine, Liberibacter solanacearum Liefting, Perez- Egusquiza & Clover Common names: zebra chip disease view more common names online... 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. -
Monitoring Bactericera Cockerelli and Associated Insect Populations in Potatoes in South Auckland
Tomato-potato psyllid 269 Monitoring Bactericera cockerelli and associated insect populations in potatoes in South Auckland G.P. Walker1, F.H. MacDonald1, N.J. Larsen1 and A.R. Wallace2 1he New Zealand Institute for Plant & Food Research Limited, Private Bag 92169 Auckland 1142, New Zealand 2he New Zealand Institute for Plant & Food Research Limited, Private Bag 4704, Christchurch 8140, New Zealand Corresponding author: [email protected] Abstract Bactericera cockerelli (the tomato-potato psyllid; TPP) and associated insects were monitored weekly in unsprayed potatoes at Pukekohe by using yellow sticky traps and sampling plants from late July 2009 until mid March 2010. TPP adult catches and egg and nymphal infestations were absent or low until mid December. Other exotic and native psyllid species dominated trap catches until TPP populations increased markedly in mid January and peaked at 120 adults per trap in late February, with egg numbers reaching 520 per plant a week later. TPP nymphs peaked at 260 per plant in early February. Micromus tasmaniae (brown lacewing) was common in spring and summer, but Melanostoma fasciatum (small hover fly) became the dominant predator, peaking at 162 eggs and 35 larvae per plant in mid January. Naturally occurring predators appear to be important biological control agents of aphids, small caterpillars and probably TPP on potatoes at Pukekohe. Keywords tomato-potato psyllid, Bactericera cockerelli, sticky traps, plant sampling, potatoes, Melanostoma fasciatum, Micromus tasmaniae. INTRODUCTION Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), (Liefting et al. 2009). It has been associated with most commonly known in New Zealand as foliar symptoms similar to those of zebra chip but tomato-potato psyllid (TPP), is a new invasive the insect vector in potatoes is unclear. -

Interspecific Interactions Within a Vector-Borne Complex Are Influenced by a Co-Occurring Pathosystem
www.nature.com/scientificreports OPEN Interspecifc interactions within a vector‑borne complex are infuenced by a co‑occurring pathosystem Regina K. Cruzado‑Gutiérrez1,2,7, Rohollah Sadeghi2,7, Sean M. Prager3, Clare L. Casteel4, Jessica Parker2, Erik J. Wenninger5, William J. Price6, Nilsa A. Bosque‑Pérez2, Alexander V. Karasev2 & Arash Rashed1,2* Potato virus Y (PVY) and zebra chip (ZC) disease are major threats to solanaceous crop production in North America. PVY can be spread by aphid vectors and through vegetative propagation in potatoes. ZC is associated with “Candidatus Liberibacter solanacearum” (Lso), which is transmitted by the tomato/potato psyllid, Bactericera cockerelli Šulc (Hemiptera: Triozidae). As these two pathosystems may co‑occur, we studied whether the presence of one virus strain, PVY°, afected the host preference, oviposition, and egg hatch rate of Lso‑free or Lso‑carrying psyllids in tomato plants. We also examined whether PVY infection infuenced Lso transmission success by psyllids, Lso titer and plant chemistry (amino acids, sugars, and phytohormones). Lso‑carrying psyllids showed a preference toward healthy hosts, whereas the Lso‑free psyllids preferentially settled on the PVY‑infected tomatoes. Oviposition of the Lso‑carrying psyllids was lower on PVY‑infected than healthy tomatoes, but Lso transmission, titer, and psyllid egg hatch were not signifcantly afected by PVY. The induction of salicylic acid and its related responses, and not nutritional losses, may explain the reduced attractiveness of the PVY‑infected host to the Lso‑carrying psyllids. Although our study demonstrated that pre‑existing PVY infection can reduce oviposition by the Lso‑carrying vector, the preference of the Lso‑carrying psyllids to settle on healthy hosts could contribute to Lso spread to healthy plants in the presence of PVY infection in a feld. -

APP201955: an Application to Release Tamarixia Triozae As a Biological Control for the Tomato Potato Psyllid (Bactericera Cockerelli)
Staff Assessment Report APP201955: An application to release Tamarixia triozae as a biological control for the tomato potato psyllid (Bactericera cockerelli) April 2016 Purpose To release from containment the psyllid parasitoid Tamarixia triozae into New Zealand to assist with the biological control of the tomato potato psyllid (Bactericera cockerelli) Application number APP201955 Application type Notified, full release Applicant Horticulture New Zealand Inc. Date formally received 27 January 2016 2 EPA advice for application APP201955 Executive Summary and Recommendation In January 2015, Horticulture New Zealand Inc. applied to the Environmental Protection Authority (EPA) to introduce the psyllid parasitoid Tamarixia triozae as a biological control agent (BCA) for the tomato potato psyllid (TPP; Bactericera cockerelli). The application was submitted on behalf of Potatoes New Zealand Inc., Tomatoes NZ Inc., Heinz-Wattie’s NZ Ltd, Vegetables NZ Inc., and NZ Tamarillo Growers Association Inc. We examined the efficacy of T. triozae to control TPP and curb transmission of Candidatus Liberibacter solanacearum, the causal agent of Zebra Chip disease, to horticulture crop plants, and the beneficial and adverse effects on the environment, market economy and on Māori and their relationship to the environment. Our assessment found that we consider it likely that the release of T. triozae will improve management of TPP which will support development of new integrated pest management (IPM) programmes. We consider it likely that IPM programmes will reduce applications of broad-spectrum insecticides which will improve the environmental impact of horticulture practices. We also consider the use of T. triozae will benefit Māori who use traditional (organic) pest control methods to cultivate taewa, kūmara and poroporo.
