“…This group may include other plant species from the Fabaceae family (such as the common bean; Pereira et al, ) as well as the Solanaceae family, as already observed by Toscano et al () in tomato and by Moura et al () in cucumber plants, where B. tabaci adults also prefer to feed and oviposit in the upper parts of the plants. The same behavior has been observed in cotton plants (Campos et al, ).…”

To control whiteflies on soybean crops in an effective and economically viable way, it is necessary to quantify the occurrence and density of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) on the leaflets. Estimating the number of B. tabaci cm‐2 on leaflets is difficult, because its distribution pattern on the various parts of the plant canopy and on the leaflet surface is unknown. The aim of this study was to evaluate the distribution of B. tabaci nymphs on soybean plants and leaflets, under greenhouse and field conditions. One hundred soybean plants infested with all nymph stages were randomly selected in a greenhouse, and 25 in a field. Of each plant, a trifoliate leaf of the middle third of the plant’s height was selected and its central leaflet was collected (greenhouse experiment), or a trifoliate leaf of each third layer (upper, middle, and lower), of which the left, central, and right leaflets were collected (field experiment). The collected leaflets were divided into 32 sections (1 cm2 per section), arranged in an array of eight rows and four columns to count whitefly nymphs. The Morisita index (Iδ), the negative binomial parameter k, and the dispersion index (I) were calculated for each leaflet, using the number of nymphs as variable. The highest population densities of whitefly nymphs were found in the middle third of the soybean plants. In leaflets from the middle third, the nymphs concentrated in the middle and bottom parts of the leaflets, whereas in the upper and lower thirds of the plant, they were randomly distributed on the leaflets.

“…The increasing number of adults per leaf, and therefore the number of eggs, might extrapolate the capacity of leaves support, causing their premature loss, and not allowing the full development of the nymphs, which did not occur on this experiment (Bellotti et al 2012). Toscano et al (2002) and Campos et al (2005) studying B. tabaci biotype B in tomato and cotton plants, observed that there was not a significant difference in the mean number of eggs in the densities of 100 and 150 insects per cage (40 cm diameter x 60 cm height). These authors also noted that the best density would be of 100 insects per cage.…”

El objetivo de este estudio fue desarrollar un método de cría de Bemisia tuberculata en plantas de yuca para la producción y el mantenimiento continuo de una colonia. La población inicial de B. tuberculata se obtuvo a partir de hojas recogidas de la planta con alta infestación de ninfas. Los adultos obtenidos fueron transferidos de la taza de plástico para jaulas de tul, en diferentes densidades. La densidad de 125 adultos de B. tuberculata por hojas fue el más adecuado para la cría. El método que se propone en este estudio ha demostrado ser eficaz y se recomienda, ya que el nivel de la población se mantuvo estable durante los experimentos.

MORAES CARBONELL ( 4 ); CESAR PAGOTTO STEIN ( 4 ); RAFAEL MAJOR PITTA ( 2 ); ALISSON FERNANDO CHIORATO ( 4 ) RESUMO Avaliou-se o comportamento de genótipos de feijoeiro sob a infestação de Bemisia tabaci (Genn.) biótipo B e Caliothrips phaseoli (Hood) em condições de campo, nas épocas de cultivo "de inverno", "das águas" e "da seca". Adotou-se o delineamento de blocos casualizados em esquema de parcelas sub-subdividida (19x3x6), com 19 genótipos (IAC Tybatã, IAC Una, FT Nobre, Pérola, Gen 96A98-15-3-32-1, Gen 96A45-3-51-52-1, IAC Alvorada, IAC Diplomata, Gen 96A3-P1-1-1, LP 98-122, LP 02-130, LP 01-38, LP 9979, BRS-Pontal, BRS-Requinte, BRS-Triunfo, BRS-Grafite, CV-48 e Z-28), três épocas de cultivos (inverno, águas e seca) e seis períodos de avaliação. As avaliações foram realizadas semanalmente, contando-se o número de ovos e ninfas de B. tabaci e ninfas de C. phaseoli em dez folíolos por parcela. Os genótipos IAC Una, Pérola, Gen 96A45-3-51-52-1, Gen 96A98-15-32-1, FT Nobre, IAC Tybatã, IAC Alvorada, LP 02-130, LP 01-38, LP 98-122, IAC Diplomata e Gen 96A3P1-1-1 foram menos ovipositados por B. tabaci no cultivo "das águas". Os genótipos Pérola, Gen 96A45-3-51-52-1, IAC Una, Gen 96A98-15-32-1, IAC Tybatã e FT Nobre foram menos infestados por C. phaseoli. A maior incidência de ninfas de mosca-branca ocorreu no fim de janeiro no cultivo "das águas" e início de maio no cultivo "da seca"; para tripés, foi em junho durante o cultivo "de inverno". A maior incidência da população de B. tabaci e C. phaseoli, ocorreu dos 46 aos 60 dias após a emergência das plantas. Palavras-chave:Phaseolus vulgaris, mosca-branca, tripes, resistência de plantas. ABSTRACT INFESTATION OF BEMISIA TABACI BIOTYPE B AND CALIOTHRIPS PHASEOLI ON BEAN GENOTYPESThe response of bean genotypes to infestation of Bemisia tabaci (Genn.) biotype B and Caliothrips phaseoli (Hood) in field conditions on the winter, rainy and dry seasons was evaluated. The experiment was arranged in a randomized blocks design with 19 genotypes (IAC Tybatã, IAC Una, FT Nobre, Pérola, Gen 96A98-15-3-32-1, Gen 96A45-3-51-52-1, IAC Alvorada, IAC Diplomata, Gen 96A3-P1-1-1, LP 98-122, LP 02-130, LP 01-38, LP 9979, BRS-Pontal, BRS-Requinte, BRS-Triunfo, BRS-Grafite, CV-48 and Z-28) Three crops seasons of (winter, rainy and dry seasons) and six periods of evaluations were considered. The evaluations consisted on counting eggs and nymphs of B. tabaci biotype B and nymphs of C. phaseoli in 10 leaflets per plot. The genotypes IAC Una, Pérola, Gen 96A45-3-51-52-1, Gen 96A98-15-32-1, FT Nobre, IAC Tybatã, IAC Alvorada, LP 02-130, LP 01-38, LP 98-122, IAC Diplomata e Gen 96A3P1-1-1 were the least oviposited by B. tabaci biotype B, in rainy season. The least presence of C. phaesoli was observed on Gen 96A45-3-51-52-1, IAC Una, Gen 96A98-15-32-1, IAC Tybatã and FT Nobre. The highest occurrence of whitefly nymphs was observed during rainy season and beginning of the dry season, while the thrips preferred the winter season. The highest incidence of the population of B. tabaci biotype B ...
