1. Biology of Bactrocera carambolae (Diptera: Tephritidae) on four hosts
ABSTRACT Bactrocera carambolae is a quarantine pest found in Brazil, restricted to the states of Amapá, Pará and Roraima. This fruit fly can potentially cause extensive socioeconomic and environmental damage in the country, if it disperse into areas where fruit is grown for exporting. The objective of this work was to study the biology of B. carambolae on

2. A Rapid and Reliable Method for Molecular Detection of Fusarium guttiforme, the Etiological Agent of Pineapple Fusariosis
Abstract Pineapple (Ananas comosus var. comosus) fusariosis is an economically important fungal disease affecting the plant and its fruit. A rapid and reliable diagnosis is the base of integrated disease management practices. Fusariosis has resulted in quarantines for pineapple products in Central America, Africa and Asia. Difficulties diagnosing and correc

3. Genome sequencing of four strains of Phylotype I, II and IV of Ralstonia solanacearum that cause potato bacterial wilt in India
Abstract Ralstonia solanacearum is a heterogeneous species complex causing bacterial wilts in more than 450 plant species distributed in 54 families. The complexity of the genome and the wide diversity existing within the species has led to the concept of R. solanacearum species complex (RsSC). Here we report the genome sequence of the four strains (RS2, RS2

4. Observations on the gall rust fungus Prospodium transformans, a potential biocontrol agent of Tecoma stans var. stans (Bignoniaceae) in South Africa
Tecoma stans var. stans, a tree originating from the Americas, is emerging as an invasive weed in South Africa. A microcyclic gall inducing rust fungus, Prospodium transformans, has been investigated as a biological control agent against this plant. Development of germinating teliospores and symptoms on host plants are described, and the optimum temperature

5. First report and characterization of Fusarium circinatum, the causal agent of pitch canker in Brazil
Pitch canker is one of the most important diseases of pine trees worldwide, including South America. The causal agent of this disease is Fusarium circinatum, a member of the Gibberella fujikuroi complex (GFC). In South America, the species is reported from Colombia, Uruguay and Chile, but is considered a quarantine organism in Brazil. In this study we charac

6. Experimental host range of Citrus leprosis virus C (CiLV-C)
Citrus leprosis (CL) is a serious threat to the citrus industry, especially for sweet oranges. For a long time, Citrus spp. were considered the only susceptible hosts. However, other plant species were also found either experimentally or naturally to be susceptible to Citrus leprosis virus C (CiLV-C). To assess the experimental host range of CiLV-C, a large

7. The need to carry out re-inventory of plant pathogenic fungi
Plant pathogenic fungi have long been documented through concerted efforts of mycologists and plant pathologists; these records have served as the basis for regional and countrywide checklists which have since been put into databases listing hosts and associated fungi. They are used by governments and scientists to formulate trade quarantine policies and det

8. A quarentena e o intercambio de germoplasma vegetal no Brasil: a atuacao do CENARGEN.
A quarentena vegetal visa prevenir a entrada de organismos nocivos em areas indenes. E apoiada por leis nacionais e fundamentada em principios biologicos. O CENARGEN executa a quarentena de germoplasma vegetal introduzido no Brasil e destinado aos programas de melhoramento genetico do SNPA. As primeiras atividades de defesa vegetal tiveram lugar no Brasil em

9. Desenho de primers e clonagem do gene do capsídeo de fitovírus para uso como controles positivos na diagnose por RT-PCR
The frequent exchange of plant material for propagation, provides a good performance of agriculture in Brazil, but exposes the country to the risk of introducing unwanted pathogens. To prevent this, the early diagnosis of pathogens of both quarantine and the non-quarantine viruses is essential. Regarding to viruses, the establishment of efficient techniques

10. Efeito dos extratos do albedo de Citrus sinensis, Lentinula edodes, Agaricus blazei e dos compostos orgânicos voláteis produzidos por Saccharomyces cerevisiae no controle da mancha preta dos citros / Effect of albedo extracts of Citrus sinensis, Lentinula edodes, Agaricus blazei and volatile organic compounds produced by Saccharomyces cerevisiae in the control of citrus black spot
The citrus black spot is a disease that restricts the export of Brazilian oranges to the countries in Europe. Except for Citrus aurantium and its hybrids, all other varieties are susceptible to the pathogen. Thus, there is great interest that this disease does not occur, since it is considered a quarantine A1 disease. Problems associated with the acquisition

11. Sistemática morfológica e molecular de ácaros fitófagos do gênero Brevipalpus Donnadieu de importância econômica e quarentária para o Brasil / Morphological and molecular systematics of phytophagous mites of brevipalpus donnadieu genus of economic and quarantine importance to Brazil
Brevipalpus Donnadieu is the most importante genus in the Tenuipalpidae family. This genus presents about 300 species distributed around the world. Brevipalpus mites present agricultural importance because they are pests of several crops and especially due to their role as vectors of serious plant viroses. In Brazil, the main Brevipalpus species are B. phoen

12. UTILISATION OF THE GAMMA RADIATION OF COBALTO - 60 AS QUARANTINE TREATMENT OF THE MEDICINAL PLANT, AROMATIC AND SEASONING PLANTS DEHYDRATED INFESTED BY LASIODERMA SERRICORNE (FABRICIUS, 1792) (COLEOPTERA, ANOBIIDAE) E PLODIA INTERPUNCTELLA (HUBNER, 1813) (LEPIDOPTERA, PYRALIDAE). / Utilização da radiação gama do Cobalto-60 como tratamento quarentenário de plantas medicinais, aromáticas e condimentares desidratadas infestadas por lasioderma serricorne (fabricius, 1792) (coleoptera, anobiidae) e plodia interpunctella (hubner, 1813) (lepidoptera, pyralidae)
The research had as objective the use of the gamma radiation of the Cobalto-60 as quarantine treatment of the medicinal plant, aromatic and seasoning plants dehydrated infested by Lasioderma serricorne and Plodia interpunctella determining the desinfestation doses to attend the criterion in the not emergency of adults of the species in study and analysing th
