• Abstract

  The whitefly (Bemisia tabaci) is one of the most important pests in the world, especially being a vector of plant viruses. B. tabaci is classified in a complex of cryptic species. In Brazil, the invasive species Middle East-Asia Minor 1, MEAM1 (known as biotype B) and Mediterranean, MED (known as biotype Q) are the main responsible for great yield losses. MEAM1 was first reported in 1992 …

• Abstract

  The whiteflies (Bemisia tabaci) are recognized as one of the most important pest of the century, mainly because they are vectors of begomoviruses. They are insects with high biological variability and are classified as a complex of species sub-divided into 11 sub groups containing at least 29 species morphologically indistinguishable. Between these species, only Middle East-Asia Minor 1 (…

• Abstract

  Potato is an essential source of food worldwide, being the third most consumed after rice and wheat. The crinivirus tomato chlorosis virus (ToCV), transmitted by whiteflies, can cause significant damage to solanaceous, mainly to tomato crops, with significant losses. This crinivirus has already been reported infecting potatoes. However, there is a lack of information about the occurrence,…

• Abstract

  Soybean (Glycine max L.) is one of the main agricultural commodities in Brazil as a source of vegetal oil and protein. In the last years, soybean production has been highly attacked by the whitefly Bemisia tabaci, that is a pest and vector of important viruses such as the Carlavirus Cowpea Mild Mottle Virus (CPMMV), causal agent of the soybean stem necrosis, diseased reported in Brazil in…

• Abstract

  The recent introduction of of Bemisia tabaci cryptic species Mediterranean, also known as biotype Q, has been causing big problems to bell pepper production in São Paulo State. Trying to get around this, producers are adopting cucumber as an alternative for bell pepper production, but high incidence of whiteflies have been observed on bell pepper. Therefore, this study aims to analyze the…
