13. Dinâmica populacional de afídeos (Hemiptera: Aphididae) em árvores cítricas no município de Nova Granada - SP / Population dynamics of aphids (Hemiptera: Aphididae) on citrus trees in Nova Granada County, São Paulo State, Brazil
Because aphids are possibly involved in the spread of viruses associated with a new and destructive disease, citrus sudden death (CSD), it is important to know their population dynamics in order to understand disease epidemiology. The goal of this research was to determine the main aphid species that colonize citrus groves [Citrus sinensis (L.) Osbeck] in CS

14. Alternative production methods of containergrown citrus nursery trees related to prevention of citrus sudden death disease. / Métodos alternativos de produção de mudas cítricas em recipientes na prevenção da morte súbita dos citros.
Citrus Sudden Death (CSD) is a new disease detected in the citrus industry in São Paulo State, Brazil. It affects all citrus varieties budded on Rangpur Lime (Citrus limonia Osbeck), causing lost of vigor and leaf brightness, root system destruction, yield reduction, degeneration of rootstock phloem tissue and death of plants in few months. CSD has a gr

15. Survey of leafhopper (hemiptera: cicadellidae) vectors of Xylella fastidiosa in citrus groves of the north coast of Bahia state. / Levantamento de cigarrinhas (Hemiptera: Cicadellidae) vetoras de Xylella fastidiosa em pomares cítricos do litoral norte da Bahia.
This study was carried out to identify vectors or potential vectors of Xylella fastidiosa Wells et al. in citrus groves of the north coast of Bahia State, Brazil, based on a faunistic survey and determination of predominant sharpshooter leafhoppers (subfamily Cicadellinae). The survey was carried out from March/2002 to February/2003 in five old sweet orange

16. Espécies de cigarrinhas (Hemiptera, Cicadellidae, Cicadellinae) em pomares de citros da região de Bebedouro, SP, com descrição de uma espécie nova de Acrogonia Stål
Sharpshooter leafhoppers (Hemiptera, Cicadellidae, Cicadellinae) in citrus groves of the area of Bebedouro, SP, with description of a new species of Acrogonia Stål. Sixteen species of Cicadellidae, subfamily Cicadellinae, were collected and identified: 11 of the tribe Cicadellini and five of the tribe Proconiini. The ten most common species, together with a

17. Resistance of Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) to the acaricide hexythiazox in citrus. / Resistência de Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) ao acaricida hexitiazox em citros.
The objective of this study was to collect baseline information for implementing an acaricide resistance management program of Brevipalpus phoenicis (Geijskes, 1939) to hexythiazox in citrus. The egg susceptibility of B. phoenicis to hexythiazox was measured by a direct contact bioassay. It was observed a significant effect of the egg developmental stage on

18. Sub-lethal effects of a copper sulfate fungicide on development and reproduction in three coccinellid species.
Copper-based fungicides reliably control various foliar diseases in citrus production, although they are suspected to exacerbate mite problems through various mechanisms. Studies have shown negative effects of various copper formulations on entomopathogenic fungi, nematodes, and parasitoids, but few have sought to measure its impact on the biology of predato
