Rearing leafhopper (Hemiptera: Cicadellidae) vectors free of Xylella fastidiosa is a requirement for studies of various aspects of vector-pathogen interactions. The selection of a plant that allows vector development but not bacterial multiplication is desirable to produce healthy vectors. In this study, two leafhopper hosts, Vernonia condensata ('boldo') and Aloysia virgata ('lixeira') were needle inoculated with citrus and coffee strains of X. fastidiosa to evaluate if these plants support pathogen colonization. The inoculated plants did not present symptoms and the pathogen was not detected by culture and PCR tests, neither soon after inoculation (7-14 days) nor later, at 1, 4, 6 and 12 months after inoculation. To obtain healthy adults of the...

Número de ínstares larvais de Tuta absoluta (Meyrick) em genótipos de tomateiro
Provedor de dados: 63
Autores: Giustolin,Teresinha Augusta; Vendramim,José Djair; Postali Parra,José Roberto.
A traça Tuta absoluta (Meyrick) é uma das principais pragas do tomateiro no Brasil e tem sido controlada quase que exclusivamente com inseticidas, o que é indesejável tanto por motivos econômicos quanto ambientais. Esses problemas podem ser minimizados com métodos alternativos de controle, tal como a resistência varietal que é uma alternativa interessante, mas que ainda precisa ser mais estudada. Visando obter mais informações sobre a relação inseto-planta, estudou-se o número de instares da traça em dois genótipos de tomateiro Lycopersicon hirsutum f. glabratum (PI 134417 -- resistente) e L. esculentum (`Santa Clara' - suscetível). O experimento foi desenvolvido em câmara climatizada em duas temperaturas (26 ± 0,5 e 30 ± 0,5ºC). As lagartas...

ABSTRACT Diachasmimorpha longicaudata is an Old World parasitoid of tephritid fruit flies that was widely introduced in the Americas to control pest species such as the Mediterranean fruit fly Ceratitis capitata. Augmentative releases in irrigated coffee plantations in semiarid regions of Brazil are under consideration and dispersal capacity of D. longicaudata in this habitat are important to develop release strategies. Approximately 2,000 individuals of D. longicaudata (5 to 7 days old) were released in the center of a fruiting coffee plantation every two weeks from Dec. 2009 to Apr. 2010. Dispersal from the central release point was monitored to the north, south, east, west, northeast, northwest, southeast and southwest at 11 distances, beginning at 4.6...
