In the absence of rootstocks meeting all these criteria, the management of the available diversity and the selection of the desirable traits are necessary. -
Section 3417. Mexican Fruit Fly Interior Quarantine
Section 3417. Mexican Fruit Fly Interior Quarantine A quarantine is established against the following pest, its hosts and possible carriers: A. Pest. Mexican fruit fly (Anastrepha ludens) B. Area Under Quarantine. 1. An area shall be designed as under quarantine when survey results indicate an infestation is present, the Department has defined the infested area and the local California County Agricultural Commissioner(s) is notified and requests the quarantine area be established. The Department shall also provide electronic and/or written notification of the area designation(s) to other California County Agricultural Commissioners and other interested or affected parties and post the area description to its website at: https://www.cdfa.ca.gov/plant/mexfly/regulation.html. An interested party may also go to the above website and elect to receive automatic notifications of any changes in the regulated or quarantine areas through the list serve option. 2. If an area is not undergoing the sterile insect technique, an infestation is present when eggs, a larva, a pupa, a mated female or five or more male or unmated female Mexican fruit fly adults are detected within three miles of each other and within one life cycle. In an area undergoing sterile insect technique the criteria for an infestation are the same except a single mated female does not constitute an infestation but counts towards an adult for five or more. 3. The initial area under quarantine shall be a minimum of 4.5 mile radius surrounding the qualifying detections being used as an epicenter. Commercial host properties shall not be split by the quarantine boundary line and the boundary line shall be expanded beyond the 4.5 miles as necessary to encompass such host material in its entirety. -

Long Flexuous Threads Associated with Hassaku Dwarf Disease of Citrus Trees
Title Long Flexuous Threads Associated with Hassaku Dwarf Disease of Citrus Trees Author(s) SHIKATA, Eishiro; SASAKI, Atsushi Citation Journal of the Faculty of Agriculture, Hokkaido University, 56(2), 219-224 Issue Date 1969-07 Doc URL http://hdl.handle.net/2115/12847 Type bulletin (article) File Information 56(2)_p219-224.pdf Instructions for use Hokkaido University Collection of Scholarly and Academic Papers : HUSCAP LONG FLEXUOUS 'IHREADS ASSOCIATED WITH HASSAKU DWARF DISEASE OF CITRUS TREES Eishiro SHlKATA (Department of Botany, Faculty of Agriculture, Hokkaido University, Sapporo, Japan) and Atsushi SASAKI (Citrus Branch of Hiroshima Agriculture Experiment Station, Mihara, Hiroshima, Japan) Received March 7, 1969 INTRODUCTION A dwarf disease of Hassaku orange trees (Citrus hassaku HORT. et Y. TANAKA), first described by TANAKA et al. (1960) in Japan, was assumed to be caused by the citrus tristeza virus (SASAKI 1963, 64, 67, TANAKA and YAMADA 1964) on the basis of host range and symptomatology studies. CHEN, MIYAKAWA and MATSUI (1967) briefly reported that long threads of lO to 13 mp in diameter of variable length were found in the dip preparations and thus the causal virus of Hassaku dwarf may be identical with tristeza. As for the tristeza virus, electron microscopic studies by KIT A]lMA et al. (1964, 1965), SILVA et al. (1965), and PRICE et al. (1966) established its average length of 2000 mp and the intracellular accumulation in phloem cells of diseased lime plants. To confirm the causal virus of Hassaku dwarf, attempts were made to observe the virus morphology in ultrathin sections of diseased plants under an electron microscope. -

Reaction of Types of Citrus As Scion and As Rootstock to Xyloporosis Virus
ARY A. SALIBE and SYLVIO MOREIRA Reaction of Types of Citrus as Scion and as Rootstock to Xyloporosis Virus THEVIRUS of xyloporosis (cachexia) (2,4, 10) is widespread in many commercial varieties of citrus ( 1, 5, 6, 8).For this reason, it is of special interest to know the reaction between it and various types of citrus that are presently used as rootstocks or may eventually be so used. This paper reports the results of tests conducted to determine this reaction for a number of different types of citrus. Materials and Methods In September, 1960, 2-year-old Cleopatra mandarin [Citrus reshni (Engl.) Hort. ex Tanaka] seedlings in the nursery were inoculated with xyloporosis virus by budding each seedling with three buds from a single old-line Bargo sweet orange [C. sinensis (L.) Osbeck] tree on Dancy tan- gerine (C. tangerina Hort. ex Tanaka) rootstock exhibiting the gummy- peg and wood-pitting type of xyloporosis symptoms. This tree was known to be carrying both xyloporosis and tristeza viruses but neither psorosis nor exocortis viruses. Two months later, each of two of these seedlings was budded just above the inoculating bud with one or another of 122 different types of citrus, each bud being taken from a tree of a nucellar line, except in the case of the monoembryonic types. Identical numbers of non-inocu- lated Cleopatra mandarin seedlings were budded with these citrus types to serve as control plants. All seedlings were cut back to allow the buds to sprout. They were inspected periodically by taking out a strip of bark at the bud-union, the last inspection being made 33 months after inocula- tion. -
Replication/Accumulation and Symptom Expression of Citrus Viroids on Some Species of Citrus and Related Genera
Fifteenth IOCV Conference, 2002—Viroids Replication/Accumulation and Symptom Expression of Citrus Viroids on Some Species of Citrus and Related Genera C. J. Barbosa, J. A. Pina, L. Navarro, and N. Duran-Vila ABSTRACT. Plants of 32 species of Citrus and related genera grafted on rough lemon root- stock were inoculated with an artificial mixture of citrus viroids containing Citrus exocortis viroid, Citrus viroid I, Citrus viroid II, Citrus viroid III and Citrus viroid IV. Infection and viroid titers were determined by sPAGE and molecular hybridization analysis. Plants in which viroid infection could not be detected were further indexed by inoculation on Etrog citron 861 S1. Under the conditions of this assay most of the species were symptomless carriers. Only Citrus excelsa, C. ichangensis, C. karna, C. latifolia, C. meyeri and C. pyriformis developed symptoms as a result of viroid infection. Comparative analysis of nucleic acid extracts from bark versus leaf blade tis- sues indicated that in 10 species, viroid that were readily detectable from bark were undetectable from leaf blade tissues by sPAGE.
