Transmission of Citrus leprosis virus C by Brevipalpus phoenicis (Geijskes) to Alternative Host Plants Found in Citrus Orchards
(Amer Phytopathological Soc, 2012-07-01)
The equivalent of US$75 million is spent each year in Brazil to control Brevipalpus phoenicis, a mite vector of Citrus leprosis virus C (CiLV-C). In this study, we investigated the possibility that hedgerows and windbreaks ...
Unsuitability of indigenous South American Rutaceae as potential hosts of Diaphorina citri
(2019-07-01)
BACKGROUND: ‘Candidatus Liberibacter asiaticus’ is transmitted by Diaphorina citri, an insect with a wide range of hosts in Rutaceae. Species related to Citrus occur in Brazilian forests where they may serve as hosts for ...
Acaricides used in conventional and organic citrus orchard: leprosis and phytoseiid mites population control
(Soc Brasileira Fruticultura, 2010-12-01)
The citrus leprosis control in São Paulo state is performed exclusively by acaricides to control the vector mite, Brevipalpus phoenicis, which increases the production costs and may affect the beneficial organism's population. ...
Dispersion patterns of Diachasmimorpha longicaudata (Hymenoptera: Braconidae) in citrus orchards in southeast Brazil.
(Biocontrol Science and Technology, Oxford, v.17, n. 4, p. 375-385, 2007., 2015)
Factors affecting prevailing population levels of Brevipalpus yothersi (Acari: Tenuipalpidae) in citrus areas affected by citrus leprosis in the State of Sao Paulo, Brazil
(2018-04-01)
Brevipalpus yothersi Baker (Acari: Tenuipalpidae) was recently confirmed as one of the main vectors of citrus leprosis. Knowledge about this mite’s biology is essential to understand its population dynamics, in order to ...
Tabela de vida ecológica do minador-dos-citros, Phyllocnistis citrella stainton (Lepidoptera: Gracillariidae)
(2004-12-01)
The construction of ecological life tables is a useful tool to understand the population dynamics of insects in the field. In this work, ecological life tables were developed for Phyllocnistis citrella (Stainton) in an ...
Spatial distribution of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) in citrus orchards
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2010-10-01)
O psilídeo Diaphorina citri Kuwayama tornou-se nos últimos anos uma das mais importantes pragas na cultura de citros, principalmente pelos prejuízos causados às plantas por ser o transmissor da bactéria causadora da doença ...
Irrigation requirements and transpiration coupling to the atmosphere of a citrus orchard in Southern Brazil
(ELSEVIER SCIENCE BV, 2011)
Crop evapotranspiration (ETc) was measured as evaporative heat flux from an irrigated acid lime orchard (Citrus latifolia Tanaka) using the aerodynamic method. Crop transpiration (T) was determined by a stem heat balance ...
Spatial variability of leaf nutrient contents in a drip irrigated citrus orchardVariabilidade espacial dos teores foliares de nutrientes em um pomar de citros sob irrigação localizada
(Associação Brasileira de Engenharia Agrícola, 2012)
This study aimed to evaluate the spatial variability of leaf content of macro and micronutrients. The citrus plants orchard with 5 years of age, planted at regular intervals of 8 x 7 m, was managed under drip irrigation. ...
