Low polymorphism revealed in new microsatellite markers for Bemisia tabaci (Hemiptera: Aleyrodidae)

G. E. Valle, Lourenção, A. L., Zucchi, M. I., and Pinheiro, J. B., Low polymorphism revealed in new microsatellite markers for Bemisia tabaci (Hemiptera: Aleyrodidae), vol. 11, pp. 3899-3903, 2012.

The silverleaf whitefly (Bemisia tabaci) is actually a complex of morphologically indistinct species that vary in their capacity to transmit plant viruses and to induce physiological disorders in plants of economic importance. The worldwide impact of this whitefly has increased greatly, as it is a vector of various types of phytovirus, especially geminiviruses, in plants of economic importance. The adaptability of B. tabaci to many regions of the world has fostered the appearance of various biotypes that attack a broad spectrum of host plants.

MtDNA variability in whitefly (Bemisia tabaci) populations in Brazil

G. E. Valle, Lourenção, A. L., Zucchi, M. I., Pinheiro, J. B., and Abreu, A. G., MtDNA variability in whitefly (Bemisia tabaci) populations in Brazil, vol. 10, pp. 2155-2164, 2011.

Bemisia tabaci (Hemiptera: Aleyrodidae) consists of a complex of morphologically indistinct biotypes that vary mainly in their capacity to transmit plant viruses and to induce physiological disorders in plants of economic importance. The adaptability of B. tabaci to many regions of the world has fostered the appearance of various biotypes and has resulted in a broad spectrum of host plants. Our goal was to identify which biotypes were present in four B. tabaci populations in Brazil. We quantified genetic variability between and within populations.
