Occurrence of Aleurothrixus aepim (Goeldi, 1886) on cassava in Western Paraná.

Abstract

This paper work recorded the occurrence of Aleurothixus aepim Goeldi in cassava plants in the West of Parana, Brazil. The species was first found in February, 2009, in an experimental area at Universidade Estadual do Oeste do Paraná (UNIOESTE), in cassava leaves of the white starch variety. The samples were collected by gathering leaves infested with whitefly nymphs, which are characterized for presenting body coated by white waxy filaments. The material was preserved in 70% ethanol, in glass bottles, and sent for identification. New outbreaks have been recorded in the beginning of 2010 and 2011 in different rural properties located in the city of Marechal Candido Rondon. However, the precise cause of the occurence of A. aepim in this region is not completely clear. In the other production regions of the State, this species has not yet been detected.
