In another study, Milanez et al (2003) reported 40 Ð 62% mortality in adult males and females D. costalimai and O. facialis caged on potted sweet orange, Citrus sinensis (L.), for 96 h (no-choice test situation). Sweet orange is a common Þeld host of these cicadellids.…”

The glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), is a major pest of grapevine (Vitis vinifera L.) in Texas and California. It is a known vector of Pierce's disease and is considered the most significant insect pest threatening the grape industry in the United States. We evaluated the preference of four host plants for feeding and oviposition by H. vitripennis adult females. We also measured the suitability of nine host plants for the growth and development of eggs and nymphs under greenhouse and laboratory conditions, respectively. Embryonic survival exceeded 85% on all tested host plants, with the exception of sweet potato, Ipomoea batatas (L.) Lam. More than 80% of the nymphs successfully reached adulthood on sweet potato, black-eyed pea [Vigna unguiculata unguiculata (L.) Walp.], and eggplant (Solanum melongena L). Developmental time of immature H. vitripennis nymphs was significantly affected by the plants on which they fed. The nymphs were more likely to die during the first instar on host plants such as Texas mountain laurel Evonymus japonica (Thunb.), or citrange Citrus sinensis × Poncirus trifoliata. Host suitability (nutrients) and stem and leaf texture, which varied among host plant species selected, seem to both play a significant role in nymphal development. Adult females were able to feed on woody plants, but a preference for black-eyed pea and sweet potato was observed. In captivity and given the plant choices offered, they deposited more egg masses on hibiscus (Hibiscus rosa-sinensis L.) and black-eyed pea.

“…Concluíram, também, que esse grupo de insetos necessita de hospedeiros alternativos para sobreviver no campo. Milanez et al (2003) verificaram que, num período de 24h, fêmeas de D. costalimai e O. facialis, alimentando-se em plantas de falso boldo, excretaram um volume líquido correspondente a 292 e 430 vezes seus volumes corpóreos, respectivamente. A mortalidade de adultos após 96 h foi menor em hospedeiros onde houve maior excreção, indicando uma relação direta entre a taxa de excreção e a adequação nutricional ao hospedeiro.…”

“…O local de alimentação na planta (Lopes, 1996), a baixa taxa de ingestão observada em citros em relação a outras plantas hospedeiras (Milanez et al, 2003) e as condições hídricas do solo que influenciam na sobrevivência e alimentação da cigarrinha na planta hospedeira (Pereira et al, 2005), possivelmente, afetam a eficiência com que diferentes espécies de cigarrinhas adquirem ou inoculam X. fastidiosa.…”

RESUMO--A cigarrinha Bucephalogonia xanthophis (Berg) (Hemiptera: Cicadellidae) é um importante vetor da bactéria Xylella fastidiosa, agente causal da clorose variegada dos citros. Este trabalho teve como objetivo identificar o local preferido de alimentação e o período de maior atividade alimentar desta cigarrinha em citros, no sentido de elucidar o comportamento alimentar relacionado à transmissão da bactéria. O local de alimentação foi estudado em ensaio de escolha, no qual 30 insetos adultos foram liberados em gaiolas de observação (n = 10) contendo uma muda de laranja-doce [Citrus sinensis (L.) Osbeck]. Após 1; 15; 21; 25; 39; 45 e 49 h da liberação, contaram-se os insetos na parte superior (ramos com brotações) e inferior (haste principal, até H"40 cm de altura) da muda. Nos ramos da parte superior, avaliou-se a preferência entre a haste, o pecíolo e o limbo foliar. Em um segundo ensaio, 20 machos e 20 fêmeas de B. xanthophis foram confinados individualmente sobre a haste de 'seedlings' de laranja-doce para determinar os períodos de alimentação, quantificando-se a excreção de 'honeydew' (medida indireta da ingestão) em períodos sucessivos de dia e noite, durante 48 h. A maioria dos indivíduos de B. xanthophis preferiu a haste dos ramos novos (62%), na parte superior da muda cítrica (91%). Nos 'seedlings', observou-se maior volume de excreção e proporção de indivíduos excretando durante a fotofase, independentemente do sexo. Portanto, em estudos de transmissão de X. fastidiosa, deve-se considerar a preferência de B. xanthophis pela haste de brotações cítricas e sua maior atividade alimentar durante a fotofase.

FEEDING SITES AND FOOD INTAKE OF Bucephalogonia xanthophis (BERG) (HEMIPTERA: CICADELLIDAE), A SHARPSHOOTER VECTOR OF Xylella fastidiosa, ON CITRUS PLANTSABSTRACT -The sharpshooter Bucephalogonia xanthophis (Berg) (Hemiptera: Cicadellidae) is an important vector of Xylella fastidiosa, a bacterium that causes citrus variegated chlorosis. This study aimed to identify the preferred feeding sites and periods of this vector on citrus, in order to improve our understanding of the feeding behavior related to the transmission of this pathogen. The feeding sites were determined in a choice experiment, in which 30 adults were released inside observation chambers (n = 10) containing a sweet orange seedling [Citrus sinensis (L.) Osbeck]. One, fifteen, twenty-one, twenty-five, thirty-nine, forty-five, and forty-nine hours after the release, the number of insects on the upper (stem with sprouts) and bottom (primary stem, up to 40 cm above soil) parts of the plant was recorded. To determine the feeding periods, 20 males and 20 females of B. xanthophis were individually confined on the stems of sweet orange seedlings, and the honeydew excretion (indirect measure of ingestion) was quantified for 48 hours, during periods of day and night. Most B. xanthophis individuals (91%) were observed on the upper part of the plant, mainly o...
