Huanglongbing (HLB), caused by ‘Candidatus Liberibacter’ spp. and transmitted the Asian citrus psyllid Diaphorina citri (ACP), is an important threat to industries worldwide, causing significant yield loss. The current recommended strategies manage HLB are eliminate HLB-symptomatic trees reduce sources of bacterial inoculum apply insecticides vector populations. objective this study was assess effectiveness importance both applied within young plots (local management), in different...
Huanglongbing (HLB) is a disease associated with the bacteria “Candidatus Liberibacter spp.” and has been devastating citrus orchards around world. Its management involves control of insect vector, Asian psyllid Diaphorina citri Kuwayama. However, indiscriminate use chemicals caused pest outbreaks eliminated natural enemies such as parasitoid Tamarixia radiata (Waterston), main agent for biological D. citri. This study assessed lethal sublethal effects insecticides recommended integrated...
COVID-19 causes more than million deaths worldwide. Although much is understood about the immunopathogenesis of lung disease, a lot remains to be known on neurological impact COVID-19. Here, we evaluated immunometabolic changes using astrocytes in vitro and dissected brain areas SARS-CoV-2 infected Syrian hamsters. We show that alters proteins carbon metabolism, glycolysis, synaptic transmission, many which are altered diseases. Real-time respirometry evidenced hyperactivation further...

IntroducaoHuanglongbing (HLB), ou Greening, e a doenca mais importante destrutiva da citricultura mundial (Bove, 2006; Gottwald et al., 2007a). Presente de forma endemica nos continentes asiatico africano ha varias decadas, essa foi recentemente detectada dois principais paises produtores citros, Brasil Estados Unidos (Colleta Filho...
The psyllid Diaphorina citri Kuwayama is one of the most important pests citrus, mainly because it vector bacterium that causes huanglongbing (HLB) or 'Greening' disease. To study spatial distribution nymphs and adults this pest, an experiment was carried out in two 'Valencia' sweet orange orchards, four 12 years age, established Matão, central area São Paulo state, Brazil. following dispersion indices were used to pest aggregation citrus plants: variance/mean relationship (I), index...
Abstract BACKGROUND Chemical control is the method most used for management of Diaphorina citri , vector phloem‐limited bacteria associated with citrus huanglongbing ( HLB ) disease. The objectives this study were to determine influence soil‐drench applications neonicotinoids (thiamethoxam and imidacloprid) on probing behaviour D. nursery trees, using electrical penetration graph EPG technique, measure settling after trees that had received these neonicotinoid treatments. RESULTS drench...
The application of artificial intelligence (AI) such as deep learning in the quality control grains has potential to assist analysts decision making and improving procedures. Advanced technologies based on X-ray imaging provide markedly easier ways insect infestation stored products, regardless whether features are visible surface grains. Here, we applied contrast enhancement algorithms peripheral equalization calcification emphasis images improve detection Sitophilus zeamais maize In...
Citrus Sudden Death (CSD), a new, graft-transmissible disease of sweet orange and mandarin trees grafted on Rangpur lime rootstock, was first seen in 1999 Brazil, where it is present the southern Triângulo Mineiro northwestern São Paulo State. The serious threat to citrus industry, as 85% 200 million State are lime. After showing general decline symptoms, affected suddenly collapse die, manner similar sour rootstock when by tristeza caused infection with virus (CTV). In tristeza-affected...
The relationship of the citrus canker bacterium Xanthomonas axonopodis pv citri with leafminer (CLM), Phyllocnistis citrella Stainton was investigated. experiment conducted under laboratory conditions at 28±2ºC, 70±10% RH and 14h photophase in a greenhouse. Sweet orange (Citrus sinensis L. Osbeck) "Caipira"cv used to rear CLM. Plants inoculated 2nd 3rd instar larvae or pupae showed high percentages (94.3, 98.3 100%, respectively) bacterium-infected leaves. damage caused by this insect...
Abstract A phylogeographic analysis inferred from the partial mitochondrial cytochrome oxidase subunit I gene (433 bp) was performed with 22 populations of Diaphorina citri Kuwayama collected in Americas and one Pacific. Eight four countries South America, 14 North Hawaii were analyzed. Twenty-three haplotypes (hp) identified they fell into two groups: hp1–8 America (group 1) hp9–23 2). Hp1 nine present highest frequencies within each population their group, 81 85% for group 1 2,...
