“…Butter & Vir (1989) suggested that densely haired genotypes may offer a more appropriate microhabitat for oviposition to B. tabaci females, which prefer to lay their eggs at the base of the trichome insertion (Omram & El-Khidir 1978, Berlinger 1986). This behavior may be an evolutionary response to selection pressure exerted by predators and parasitoids (Butter & Vir l989), as natural enemies are more ef icient on glabrous or on less-hairy leaves than on densely haired ones (Li et al 1987).…”

“…In horticultural crops, enormous losses caused by this biotic constraint have been widely recognized (Berlinger, 1986;Lapidot and Friedmann, 2002;Morales, 2011;Borah and Dasgupta, 2012). Literature available have documented that in pepper, host resistance to B. tabaci is mainly mediated by morphological traits of plants, such as leaf trichomes and leaf thickness (Firdaus et al, 2011).…”

“…Studies of plant resistance to the vector B. tabaci have found that this phytophagous is affected mainly by the external/physical characteristics of the leaf surface, such as hairiness, glandular trichomes, leaf shape and cuticle thickness (Berlinger, 1986;Boiça et al, 2007;Oriani and Vendramim, 2010;Oriani et al, 2011). Resistance to B. tabaci and its relation to plant morphological traits has been well documented in other crops, such as tomato, cotton, and cassava (Bellotti and Arias, 2001;Boiça et al, 2007;Oriani and Vendramim, 2010).…”

The high diversity of chili pepper (Capsicum annuum L.) in Mexico offers an excellent alternative to search for wild and semi-domesticated genotypes as sources of resistance to the complex Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae)-Begomovirus, which has caused enormous losses in commercial production of various horticultural crops. The goal of the present work was to characterize ex situ 18 genotypes of C. annuum from southern Mexico through 47 morphological descriptors, and to evaluate its response to the B. tabaci-Begomovirus complex. Morphological characterization showed the variables calyx annular constriction (CAC), number of branch bifurcation (NBB), and calyx pigmentation (CP) had the highest variation. Principal components analysis (PCA) of 47 morphological characteristics showed that 12 components were selected as meaningful factors. These components explained 94% of the variation. Cluster analysis showed three major clusters and seven sub-clusters. On the other hand, evaluation of the response to B. tabaci-Begomovirus showed that the genotypes have differential susceptibility to this vector-pathogen complex. Genotypes 'Chawa', 'Blanco', 'Maax' and 'X´catic' were into the low susceptibility to B. tabaci and low severity of viral symptoms. Surprisingly, the genotype 'Simojovel' showed high susceptibility to whitefly, but was grouped into genotypes with low symptom severity. This study shows the potential of native germplasm of pepper to explore sources of resistance to the B. tabaci-Begomovirus complex.

“…Entre os fatores que influenciam a preferência do inseto para oviposição estão as características físicas da superfície foliar, tais como a pilosidade, a cor e a forma da folha, o microclima da folha, além da presença de tricomas glandulares (Mound 1962, Ohnesorge et al 1980, Berlinger 1986). Os tricomas podem interferir mecanicamente na oviposição, na fi xação e na alimentação de insetos em razão de quatro principais características: densidade, ângulo de inserção, comprimento e tipo (Channarayappa et al 1992).…”

-The objective of this work was to evaluate the infl uence of the leaf surface, the insect geotropic behavior and the type of foliar trichome on Bemisia tabaci (Genn.) biotype B oviposition on tomato leaves. Bemisia tabaci females were confi ned in acrylic boxes in which tomato leafl ets were fi xed at the bottom and top part of the boxes to allow insects to access the leaf surface to be tested (adaxial and/or abaxial) in both no-choice and free choice tests. Oviposition was always higher when the leaf was offered at the top of the box and preferably at the abaxial leaf surface. The effects of leaf trichomes (glandular and non glandular) on B. tabaci oviposition was evaluated by offering the abaxial surface of tomato leafl ets to females after a 70% ethanol wash to remove glandular exsudates against a control treatment (without a ethanol wash). Oviposition was concentrated mostly near to non glandular trichomes, showing whitefl y females can discriminate among the trichomes.KEY WORDS: Host selection, oviposition preference, glandular trichome, trichome exsudate RESUMO -Avaliou-se a infl uência da face foliar, do comportamento geotrópico do inseto e do tipo de tricoma foliar sobre a oviposição de Bemisia tabaci (Genn.) biótipo B em folhas de tomateiro. Para avaliação desses efeitos foram realizados vários ensaios nos quais as fêmeas foram confi nadas em caixas de acrílico. Folíolos de tomateiro foram fi xados no topo e na base das caixas, de tal forma a permitir o acesso dos insetos às faces adaxial e abaxial de maneira isolada e concomitante (com e sem chance de escolha). Os insetos sempre depositaram maior número de ovos quando a superfície foliar se encontrava no topo da caixa e, de maneira geral, preferiram depositar seus ovos na face abaxial dos folíolos. Para avaliar o efeito do tipo de tricoma (glandular e não-glandular) sobre a oviposição de B. tabaci, a face abaxial dos folíolos de tomateiro foi oferecida a cerca de 30 fêmeas para oviposição em cada caixa de acrílico. Foram oferecidos folíolos previamente lavados com etanol a 70% (de forma a eliminar os exsudatos glandulares) e sem lavagem prévia. A maior parte da oviposição ocorreu ao lado dos tricomas não-glandulares, demonstrando que o inseto discrimina o tipo de tricoma. PALAVRAS-CHAVE: Seleção hospedeira, preferência para oviposição, tricoma glandular, exsudato do tricoma A mosca-branca Bemisia tabaci (Genn.) biótipo B é atualmente uma das principais pragas do tomateiro, difícil de ser controlada devido ao seu hábito de permanecer na face abaxial das folhas (Villas Boas et al 1997). Os danos desse biótipo são mais intensos em função da sua maior agressividade, que resulta da maior fecundidade, ampla gama de hospedeiros, alta resistência aos inseticidas e capacidade de causar desordens fi siológicas nas plantas (Costa & Brown 1990, Prabhaker et al 1998.As fêmeas de B. tabaci depositam seus ovos preferencialmente na face abaxial das folhas mais novas (Simmons 1994(Simmons , 1999, talvez pelo fato de a face abaxial apresentar cutícula geralmen...
