“…Tanto ninfas como adultos alimentam-se da seiva do floema das plantas de centenas de espécies vegetais, causando danos diretos como manchamento, amarelecimento e queda das folhas, reduzindo o vigor das plantas, e também danos indiretos, devido à excreção de honeydew que favorece o desenvolvimento de fungos, e à transmissão de vírus (Lenteren & Noldus 1990, Byrne & Bellows 1991.…”

-Whitefly control using resistant cultivars can be considered the ideal option in integrated pest management programs. Squash cultivars and lines with different genealogies have been developed and released by private and public research institutions. However, little information is available about the resistance or susceptibility of those genotypes to insects. The main squash (Cucurbita spp.) cultivars available in the Brazilian market were evaluated as to Bemisia tabaci biotype B resistance, under greenhouse conditions. The cultivar 'Golden Delight' was the most attractive to adults, while 'Menina Brasileira', 'Bárbara' and 'Atlas' presented the lowest numbers of adults on the abaxial leaf surfaces. Oviposition was evaluated in free-choice and no-choice tests. 'Novita', 'Exposição' and 'Caserta' behaved as resistant and showed oviposition nonpreference as the resistance mechanism. The cycle from egg to adult emergence was determined in six genotypes. In 'Golden Delight', the duration of this cycle was the shortest one (24.9 days), and the percentage of adult emergence, the highest one (93.8%), thus indicating that this cultivar is suitable to the insect. On the other hand, 'Exposição' and 'Menina Brasileira' prolonged this cycle (35.8 and 33.5 days, respectively) and reduced the adult emergence (46.3 and 58.1%), showing to be resistant.

“…Many attempts have been made to control B. tabaci. Because of their high reproductive rate, multiple generations per year (Byrne & Bellows, 1991;Brown et al, 1995), and ability to rapidly develop resistance to insecticides (Palumbo et al, 2001), the whitefly is very difficult to control through conventional approaches. Thus, biological control becomes the primary method to suppress whitefly populations in agroecosystems.…”

Abstract. The relative suitability of three prey organisms, Bemisia tabaci (Gennadius) eggs, B. tabaci nymphs, and Myzus persicae (Sulzer), to the ladybird Propylea japonica (Thunberg) was evaluated under laboratory conditions. The larvae developed fastest when fed M. persicae, and slowest on B. tabaci eggs. When fed M. persicae, all larvae successfully developed into adult with a growth index (i.e., percent pupation/larval period in days) of 13.16 and development rate of 0.096. The longevity of starving adults was 4.7 ± 0.2 days. In contrast, when fed B. tabaci eggs, all larvae survived to the second instars, 56.7% of which survived to the third instars, 13.3% to the fourth instars; only 6.7% of larvae survived to the pupal stage and the pupae developed into abnormal adults that died shortly. When fed B. tabaci nymphs, all larvae survived and successfully developed into adults with a growth index of 10.71 and development rate of 0.083. The adult body mass was greater when larvae fed M. persicae, compared to adults eclosing from larvae fed B. tabaci nymphs. On the basis of these findings, the order of suitability of three prey organisms for P. japonica is M. persicae > B. tabaci nymph > B. tabaci egg. This is the first record that P. japonica can complete its development when feeding exclusively on whitefly nymphs.

“…Fatores como temperatura, vento, chuva e umidade relativa podem explicar por que cultivares pilosas abrigam altas populações de mosca-branca (Byrne & Bellows, 1991). Folhas mais pilosas podem interferir no deslocamento do ar, aumentando a umidade na superfície inferior das folhas (Chu et al, 1995).…”

Resumo -O objetivo deste trabalho foi avaliar a preferência de Bemisia tabaci biótipo B para oviposição em cultivares de algodoeiro. Em teste com chance de escolha, a cultivar Deltapine Acala 90, pilosa, foi a mais preferida para oviposição (6,11 ovos/cm 2 de folha) em relação a Antares, glabra, (0,49 ovos/cm 2 de folha). A preferência para oviposição da mosca-branca não foi influenciada pelas cultivares em teste sem chance de escolha. Considerando o índice de preferência para oviposição, a cultivar Deltapine Acala 90 foi classificada como estimulante, e Antares como deterrente, demonstrando resistência do tipo não-preferência para oviposição a B. tabaci biótipo B.Termos para indexação: algodão, resistência a agente daninho, inseto nocivo, infestação, reprodução. Preference of Bemisia tabaci biotype B oviposition in cotton cultivarsAbstract -The objective of this work was to evaluate the oviposition preference to Bemisia tabaci biotype B in cotton cultivars. In free choice test, Deltapine Acala 90, pilose cultivar, was the most preferred for oviposition (6.11 eggs/cm 2 of leaf) in relation to Antares, smooth leaf, (0.49 eggs/cm 2 of leaf). The oviposition preference of whitefly was not influenced by cultivars in no-choice test. The oviposition preference index classified Deltapine Acala 90 as stimulant, while Antares was classified as deterrent to insect oviposition, showing oviposition non-preference type to B. tabaci biotype B.
