1. Evaluation of Lignins of Trunk and Roots from Citrus sinensis L. Osbeck: A Large Available Brazilian Biomass
Citrus biomass is a source of biobased products and presents extensive chemical diversity. Among the structural macromolecules, lignins have been used in resins, bioplastics, and nanoencapsulation. Brazil has a large source of lignins, which are orange trees removed from groves that need to be renewed. However, the knowledge about these lignins is limited an

2. Thermal hygrometric requirements for the rearing and release of Tamarixia radiata (Waterston) (Hymenoptera, Eulophidae)
Thermal hygrometric requirements for the rearing and release of Tamarixia radiata (Waterston) (Hymenoptera, Eulophidae). Tamarixia radiata is the main agent for the biological control of Diaphorina citri in Brazil with a parasitism rate ranging from 20 to 80%. This study investigated the influence of temperature on the development, fecundity and longevity of

3. First Report of Citrus Aleurocanthus woglumi Ashby (Hemiptera: Aleyrodidae) in the State of Paraná, Brazil
The citrus blackfly Aleroucanthus woglumi Ashby, (Hemiptera Aleyrodidae) is an important pest that occurs in citrus groves, native to south-east Asia. In Brazil, according to the Ministry of Agriculture, this is a quarantine pest (A2) under official control IN 52, 2007 (MAPA) and is not widespread in the country. The insect can infest more than 300 host plan

4. Fitoextração em solo contaminado com metais pesados / Phytoextraction of soil contaminated with heavy metals
The industrial and urban progress associated with increased production of consumer goods has resulted in the generation of waste, which, for a long time, was indiscriminately discarded in the environment, causing damage usually irreversible to recover. Two experiments were conducted in soils contaminated with heavy metals: the first aimed at the disposal of

5. Synthetic sex pheromone of citrus leafminer in Brazilian citrus groves.
Abstract ? The objective of this work was to determine the best conditions of use of the synthetic sex pheromone of Phyllocnistis citrella Stainton for monitoring this species in citrus groves in northeastern Brazil. Pheromone doses (0.0, 0.1, 1, 10 and 100 µg) and longevity (1, 15, 29, 43 and 57-day-old lures) and trap height (0.5, 1.5 and 2.5 m), color (g

6. Synthetic sex pheromone of citrus leafminer in Brazilian citrus groves.
O objetivo deste trabalho foi determinar as melhores condições de uso do feromônio sexual sintético de Phyllocnistis citrella Stainton para o monitoramento dessa espécie em pomares de citros no Nordeste do Brasil. Foram avaliados: doses (0,0, 0,1, 1, 10 e 100 µg), duração (1, 15, 29, 43 e 57 dias de exposição do feromônio sexual sintético), altur

7. DRIS norms for 'Valencia' sweet orange on three rootstocks.
Diagnosis and Recommendation Integrated System (DRIS) applies nutrient ratios instead of the isolated concentration values of each nutrient in interpretation of tissue analysis. The objectives of this research were to establish adequate DRIS norms for 'Valencia' sweet orange irrigated commercial groves budded on three rootstocks and correlate indexes of nutr

8. Calda sulfocálcica em pomares de citros: evolução da resistência em Brevipalpus phoenicis (Acari: Tenuipalpidae) e impacto sobre Iphiseiodes zuluagai (Acari: Phytoseiidae) / Lime sulfur in citrus groves: resistance evolution in Brevipalpus phoenicis (Acari: Tenuipalpidae) and impact on Iphiseiodes zuluagai (Acari: Phytoseiidae)
The use of the lime sulfur as an alternative product for controlling Brevipalpus phoenicis (Geijskes) has intensified in Brazilian citrus groves. The lime sulfur is the only efficient product used to control B. phoenicis and certified by organic producers with an average of 11 sprayings per year. Due to intense use of this product, the major objectives of th

9. Distribuição espacial e temporal, inimigos naturais e tabela de vida ecológica de Diaphorina citri Kuwayama (Hemiptera: Psyllidae) em citros em São Paulo / Spatial and seasonal distribution, natural enemies and ecological life table of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) in citrus groves in São Paulo
O "huanglongbing" (HLB), ou "greening" dos citros, tem sido considerada a pior e mais destrutiva doença que ocorre em cultivares comerciais de citros do mundo. Até hoje, não se conhecem medidas eficientes para o controle da doença. Apesar disso, são recomendadas três medidas que podem reduzir a disseminação da mesma, (1) propagação de material sadi

10. Incidência de cancro cítrico (Xanthomonas axonopodis pv. citri) em pomares de laranjeiras 'Valencia' com poda sanitária e pulverizações com produtos cúpricos, abamectin e calda sulfocálcica / Incidence of citrus canker (Xanthomonas axonopodis pv. Citri) in 'Valencia' groves after sanitary prunings, copper, abamectin and lime sulfur sprays
O cancro cítrico (Xanthomonas axonopodis pv. citri Vauterin et al.) está presente em praticamente todos os continentes, causando prejuízos, por vezes expressivos à produção de citros. O estudo de medidas de controle assume grande importância, principalmente em áreas onde a doença atingiu o nível endêmico. O objetivo deste trabalho foi estudar form

11. Resistance of Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) to acaricides that inhibit cellular respiration in citrus groves / Resistência de Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) a acaricidas inibidores da respiração celular na cultura dos citros
Acaricides that affect the cellular respiration process, specifically in the energy production (ATP), have been an important component in acaricide resistance management programs. Basically, these acaricides interfere in the oxidative phosphorilation or electron transportation in the mitochondria, by inhibiting or disrupting some specific process. This group

12. Establishment of a trap cropping strategy for controlling sharpshooter vectors of Xylella fastidiosa in citrus groves / Estudos básicos para a utilização de plantio-isca visando ao controle de cigarrinhas vetoras de Xylella fastidiosa em pomares cítricos
Clorose Variegada dos Citros (CVC), causada pela bactéria Xylella fastidiosa Wells et al., tem causado grandes perdas na citricultura do estado de São Paulo, afetando cerca de 40% das plantas de laranja doce. A bactéria é transmitida por 12 espécies de cigarrinhas sugadoras de xilema (Hemiptera: Cicadellidae) da subfamília Cicadellinae. O manejo da CVC
